Efficacy of pericapsular nerve group (PENG) block on perioperative pain management in elderly patients undergoing hip surgical procedures: a protocol for a systematic review with meta-analysis and trial sequential analysis

INTRODUCTION

An increasing number of elderly patients suffer from hip diseases associated with moderate to severe perioperative pain during the accelerating global ageing process. Optimal analgesia can decrease perioperative complications and facilitate elderly patients' perioperative recovery. Pericapsular nerve group (PENG) block is a relatively new, analgesia adequate and motor-sparing block technique for perioperative pain management of hip diseases. However, the efficacy of PENG block remains unclear as the limited clinical evidence. Then, we will perform a protocol for a systematic review and meta-analysis to identify the efficacy of PENG block for perioperative pain management.

METHODS AND ANALYSIS

PubMed, Ovid Medline, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, Chinese BioMedical Literature, Wanfang and VIP databases will be searched from inception to August 2022 to identify randomised controlled trials of elderly patients accepting PENG block for hip diseases. The primary outcome will be the pain intensity after pain management. Secondary outcomes will be quadriceps strength, perioperative rescue analgesia information and perioperative complications. Assessment of heterogeneity will be primarily inspected by forest plots. If there is no indication of funnel plot asymmetry, a random-effects meta-analysis will be performed. The Cochrane risk-of-bias tool, Grading of Recommendations Assessment, Development and Evaluation and trial sequential analysis will be conducted to evaluate the evidence quality and control the random errors. Funnel plots and Egger's regression test will be performed to evaluate publication bias.

ETHICS AND DISSEMINATION

Ethical approval was not required for this systematic review protocol. The results will be disseminated through peer-reviewed publications.

Fascia iliaca compartment block can reduce the incidence of early post-operative cognitive impairment in elderly patients with high-risk hip replacement

Objective

In this study, we aimed to observe the effects of ultrasound-guided fascia iliaca compartment block (FICB) combined with hypobaric spinal anesthesia on post-operative pain and cognitive function in elderly patients with high-risk hip replacement.

Methods

A total of 84 elderly patients-aged 65-85 years, with American Society of Anesthesiologists physical status III-IV, and scheduled for hip arthroplasty between September 2021 and May 2022-were selected. One or more organs with moderate to severe impairment were included in all patients. The patients were randomly divided into a hypobaric spinal anesthesia group (group C, control group) and an ultrasound-guided FICB combined with hypobaric spinal anesthesia group (group E, experimental group). Group C was given 3.5 mL of 0.32% ropivacaine hypobaric spinal anesthesia, and group E received ultrasound-guided FICB combined with 3.5 mL of 0.32% ropivacaine hypobaric spinal anesthesia. The patients were compared using the visual analog scale (VAS) for pain, Harris hip function score, and simple Mini-Mental State Examination (MMSE) scale. Blood β-amyloid (Aβ) and neuronal microtubule-associated protein (tau) levels were measured. We compared intraoperative conditions and post-operative complications between the two groups to assess the effects of FICB combined with hypobaric spinal anesthesia on post-operative pain and cognitive function in elderly patients with high-risk hip replacement.

Results

At 1 and 3 days after the operation, patients in group C had significantly higher VAS and lower MMES scores than those in group E. The differences were statistically significant at 1 (P < 0.01) and 3 (P < 0.05) days after the operation. At 1 day after operation, the Harris score of patients in group C was significantly lower than that of patients in group E (P < 0.05). The Aβ and tau levels of patients in group C were significantly higher than those of patients in group E at 1 day after the operation (P < 0.01). The Aβ levels of patients in group C were significantly higher than those of patients in group E at 3 days after the operation (P < 0.05). The intraoperative conditions and post-operative complication rates did not differ significantly between the two groups. At 1 day before and 5 days after the operation, there was no difference in any of the indicators.

Conclusion

By lowering pain and managing Aβ and tau protein concentrations, FICB can successfully lower the incidence of early post-operative cognitive impairment in elderly patients with high-risk hip replacement.

The Efficacy and Safety of Regional Nerve Blocks in Total Hip Arthroplasty: Systematic Review and Direct Meta-Analysis

BACKGROUND

Regional nerve blocks may be used as a component of a multimodal analgesic protocol to manage postoperative pain after primary total hip arthroplasty (THA). The purpose of our study was to evaluate the efficacy and safety of regional nerve blocks after THA in support of the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Management.

METHODS

We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials for studies published prior to March 24, 2020 on fascia iliaca, lumbar plexus, and quadratus lumborum blocks in primary THA. All included studies underwent qualitative and quantitative homogeneity testing followed by a systematic review and direct comparison meta-analysis to assess the efficacy and safety of the regional nerve blocks.

RESULTS

An initial critical appraisal of 3,382 publications yielded 11 publications representing the best available evidence for an analysis. Fascia iliaca, lumbar plexus, and quadratus lumborum blocks demonstrate the ability to reduce postoperative pain and opioid consumption. Among the available comparisons, no difference was noted between a regional nerve block or local periarticular anesthetic infiltration regarding postoperative pain and opioid consumption.

CONCLUSION

Local periarticular anesthetic infiltration should be considered prior to a regional nerve block due to concerns over the safety and cost of regional nerve blocks. If a regional nerve block is used in primary THA, a fascia iliaca block is preferred over other blocks due to the differences in technical demands and risks associated with the alternative regional nerve blocks.

Effects of fascia iliaca compartment block as an adjunctive management to parecoxib for pain control after total hip arthroplasty

BACKGROUND

This retrospective study investigated the effects of fascia iliaca compartment block (FICB) as an adjunctive management to parecoxib for pain control after total hip arthroplasty (THA).

METHODS

A total of 72 patient records of THA were included in this retrospective study. All patients received parecoxib and were allocated to either the treatment group (n = 36) or the control group (n = 36). In addition, patients in the treatment group underwent FICB. The primary outcome was pain intensity measured using a resting and moving visual analog scales (VASs). The secondary outcomes were inflammatory factors (interleukin 6 and C-reactive protein) and occurrence rate of adverse events.

RESULTS

Patients in the treatment group had better outcomes in the resting VAS (12 hours, P < .01; 24 hours, P < .01; 36 hours, P = .01; 72 hours, P = .03), moving VAS (12 hours, P < .01; 24 hours, P < .01; 36 hours, P = .02; 72 hours, P = .02), serum interleukin 6 (P < .01), and C-reactive protein (P < .01) than those in the control group at different time points. In addition, there were no significant differences in the occurrence rate of adverse events.

CONCLUSION

The findings of this study demonstrated that the effects of FICB as an adjunctive management to parecoxib are superior to those of parecoxib alone for pain control after THA.

Transmuscular Quadratus Lumborum Block versus Infrainguinal Fascia Iliaca Nerve Block for Patients Undergoing Elective Hip Replacement: A Double-blinded, Pilot, Randomized Controlled Trial

Purpose

Transmuscular quadratus lumborum (TQL) block has been described as an effective option for postoperative analgesia in patients undergoing hip replacement with single injection described as providing analgesia for up to 24 h. We hypothesize that a TQL block, when compared to fascia iliaca block (FIB), will provide better analgesia and less motor block in the initial 24-h postoperative period.

Patients and Methods

Fifty patients undergoing elective hip replacement surgery, ASA I–III, were included in the study. Patients were randomized into two groups. Patients in group A received spinal anesthesia followed by FIB. Patients in group B received spinal anesthesia followed by TQLB. Postoperative pain scores and motor block were assessed at 6 and 24 hours. The primary outcome measure was 24 h total morphine consumption. Secondary outcome measures included pain score (VNS) and motor block (modified Bromage scale) at 6 and 24 h postoperatively.

Results

There was no statistical difference in morphine consumption between the two groups (p-value 0.699). There was no difference in pain scores at 6 h (p-value 0.540) or 24 h (p-value 0.383). There was no difference in motor block at 6 h (p-value 0.497) or at 24 h (p-value 0.773).

Conclusion

Transmuscular quadratus lumborum block along with spinal anesthesia for patients undergoing elective hip replacement surgery does not reduce opioid consumption or motor weakness when compared to fascia iliaca block. The results and conclusion apply to a dose of 20 mL of 0.25% bupivacaine used in each group.

Effect of suprainguinal fascia iliaca compartment block on postoperative opioid consumption and functional recovery in posterolateral-approached total hip arthroplasty: a single-blind randomized controlled trial

INTRODUCTION

Posterolateral-approached total hip arthroplasty (PLTHA) is followed by moderate to severe postoperative pain. Suprainguinal fascia iliaca compartment block (SFICB) has been proposed as a promising analgesia technique.

METHODS

Data from 86 patients scheduled for PLTHA with spinal anesthesia were analyzed in this prospective randomized controlled trial. Patients were randomly divided into two groups of 43 patients each. As opposed to the control group (group C), ropivacaine group (group R) received additional SFICB using 40 mL of 0.375% ropivacaine. As primary endpoint, blind observers noted total morphine consumption at postoperative 48 hours. Secondary endpoints were pain at rest and mobilization on 0-10 Numeric Rating Scale (rest and dynamic NRS) at fixed time points (1 hour and 6 hours after surgery, and at day 1 and day 2 at 8:00, 13:00 and 18:00 hours), walking performance at day 1 and day 2; postoperative complications including morphine-related side effects or orthostatic intolerance symptoms such as dizziness, nausea, blurred vision or vasovagal syncope.

RESULTS

A 48-hour morphine consumption (mg; median (IQR)) was significantly lower in group R than in group C (11 (8.5-15.5)) vs 26 (21-33.5), p<0001), as well as incidence of morphine-related side effects such as nausea at day 1 (p=0.04) and day 2 (p<0.01). Rest and dynamic NRS were globally significantly lower in group R than in group C (p<0.01). Group R showed less orthostatic intolerance at day 1 (p<0.001) and day 2 (p<0.01) and better functional walking performance at day 1 (<0.001) and day 2 (<0.001).

DISCUSSION

In PLTHA, SFICB provides opioid sparing, improved postoperative pain control, and enhanced functional recovery.

Applicability and effectiveness of ultrasound combined with nerve stimulator-guided lumbosacral plexus block in the supine versus lateral position during surgeries for lower limb fracture-a prospective randomized controlled trial

BACKGROUND

Patients with lower limb fracture often have acute pain and discomfort from changes in position, and such pain affects early postoperative recovery. This study aimed to compare the applicability and effectiveness of ultrasound combined with nerve stimulator-guided lumbosacral plexus block (LSPB) in the supine versus lateral position during lower limb fracture surgery.

METHODS

We included 126 patients who underwent elective internal fixation for lower limb fracture who were divided into the S group and the L group by the random number table method and underwent LSPB guided by ultrasound combined with a nerve stimulator in the supine and lateral positions, respectively. The primary outcome was the dose of sufentanil used in surgery. The secondary outcomes were the maximum VAS (visual analogue scale) pain score at position placing for LSPB, the time of position placing, the time for nerve block,the number of puncture attempts,the haemodynamic indicators, the VAS score at 1, 12, and 24 h following surgery, postoperative satisfactory degree to analgesia and adverse events related to nerve block.

RESULTS

There was no statistically significant difference in dose of sufentanil used between the two groups(P = 0.142). The maximum VAS pain score at position placing(P < 0.01), the time of position placement(P < 0.01), the time for lumbar plexus block and the time of puncture attempts were significantly lower in the S group than in the L group (P < 0.01). However, the time for sacral plexus block was higher in the S group than in the L group (P = 0.029). There was no significant difference in haemodynamic indicators,number of puncture attempts for the sacral plexus, postoperative VAS scores, postoperative satisfactory degree to analgesia or adverse events related to nerve block between the two groups (all P > 0.05).

CONCLUSIONS

Our study provides a more comfortable and better accepted anaesthetic regimen for patients undergoing lower limb fracture surgery. LSPB in the supine position is simple to apply and has definite anaesthetic effects. Additionally, it has a high level of postoperative analgesia and therefore should be widely applied.

TRIAL REGISTRATION

The trial was registered prior to patient enrolment at the Chinese Clinical Trail Registry (Date:11/03/2021 Number: ChiCTR2100044117 ).

Effect of Ultrasound-Guided Fascia Iliac Compartment Block on Serum NLRP3 and Inflammatory Factors in Patients with Femoral Intertrochanteric Fracture

Objective

To investigate the effects of ultrasound-guided fascia iliac compartment block (FICB) on patients' postoperative pain and inflammatory factors as well as nucleotide-binding domain and leucine-rich repeat (NLR) family, pyrin domain-containing 3 (NLRP3) in femoral intertrochanteric fracture.

Methods

This single-blind randomized controlled study included 231 patients with femoral intertrochanteric fracture treated in our hospital from January 2017 to December 2020. All patients were randomized into two groups, the FICB group (n = 116) and the general anesthesia group (control group, n = 115). The serum NLRP3 levels and inflammatory factors were evaluated. The heart rate (HR), mean arterial pressure (MAP), and SpO₂ values were recorded. Pain condition was measured by the visual analogue scale (VAS) score. Harris score was performed for positive hip function.

Results

The values of HR and MAP were significantly lower after anesthesia induction in FICB groups compared with the control group. However, no significant difference was found for SpO₂. Compared with the control group, the VAS scores within 72 h after surgery were all markedly lower in the FICB group than in the control group and showed no significant difference at 1 week after surgery. The levels of NLRP3 and interleukin 6 (IL-6) were significantly lower in FICB patients at 1 h, 6 h, 24 h, 48 h, and 72 h after surgery compared with the control group. Tumor necrosis factor-α (TNF-α) showed a significant lower level in the FICB group at 1 h and 6 h after surgery, and significant lower levels of C-reactive protein (CRP) were found at 1 h and 24 h after surgery compared with the control group. Positive correlation was found between NLRP3 and IL-6, as well as CRP and VAS scores after 1 h of the surgery. No significant difference was found for both Harris score and postoperative complications between the two groups.

Conclusion

Fascia iliac compartment block could reduce the postoperative pain, which might be associated with the decrease of the serum levels of NLRP3, CRP, IL-6, and TNF-α in femoral intertrochanteric fracture patients.

Comparison Between Ultrasound-Guided Suprainguinal Fascia Iliaca Block and Anterior Quadratus Lumborum Block for Total Hip Arthroplasty: A Prospective, Double-Blind, Randomized Controlled Trial

BACKGROUND

Nerve block is a key technique in postoperative analgesia for total hip arthroplasty (THA). This study aimed to compare ultrasound-guided suprainguinal fascia iliaca block (SFIB) and anterior quadratus lumborum block (AQLB) in patients undergoing primary THA.

METHODS

In this prospective, double-blind, randomized controlled trial, 100 patients undergoing primary THA under general anesthesia were randomly allocated to receive an ultrasound-guided SFIB + sham AQLB (SFIB group), or an ultrasound-guided AQLB + sham SFIB (AQLB group). Before wound suture, all patients received periarticular infiltration analgesia which the local anesthetic was injected into joint capsule, exposed gluteal and abductor muscles, peritrochanteric zone, and subcutaneous tissue under the incision as multiple sites. The primary outcome was postoperative morphine consumption within 24 hours after surgery. Secondary outcomes were the time to first rescue analgesia, postoperative pain assessed on the visual analog scale, postoperative quadriceps strength, the time to hospital discharge, and the incidence of postoperative complications.

RESULTS

There were no significant differences between the 2 groups concerning morphine consumption within 24 hours after surgery (P = .774), the time to first rescue analgesia (P = .890), the time to hospital discharge (P = .532), and the incidence of postoperative complications (P > .05). The visual analog scale pain scores at rest and during motion also were similar at all time points (P > .05). Significantly more patients in the SFIB group experienced quadriceps muscle weakness at 2 hours (P = .008) and 6 hours (P = .009) after surgery.

CONCLUSION

Under the circumstances of this study, when combined with periarticular infiltration analgesia, the SFIB provided similar pain relief compared with AQLB in patients undergoing THA, but was associated with muscle weakness within 6 hours after surgery.

Pericapsular Nerve Group (PENG) Block versus Supra-Inguinal Fascia Iliaca Compartment Block for Total Hip Arthroplasty: A Randomized Clinical Trial

This study compared the effects of the pericapsular nerve group (PENG) block and supra-inguinal fascia iliaca compartment block (FICB) on postoperative analgesia and quadriceps strength following total hip arthroplasty under general anesthesia. A total of 58 patients were randomized to receive either PENG block (PENG group) or supra-inguinal FICB (FICB group) following anesthetic induction. The primary outcomes were the postoperative pain scores. Patients were randomized to receive either PENG block or supra-inguinal FICB following anesthetic induction. Pain scores at rest and with movement were assessed preoperatively, at the postanesthesia care unit (only at rest), and at 6, 24, 36, and 48 h postoperatively. Opioid consumption was also assessed for 48 h postoperatively. Quadriceps strength measurements were performed preoperatively, at 6, 24, and 36 h postoperatively. In total, 54 patients completed the study: 27 in the PENG group and 27 in the FICB group. Despite lower pain scores at rest in the PENG group at postoperative 6 and 24 h, there were no significant differences in the pain scores at rest and during movement between the two groups during postoperative 48 h in the linear mixed model analysis (p = 0.079 and p = 0.323, respectively). Cumulative opioid consumption up to postoperative 48 h was also similar in the two groups (p = 0.265). The changes in quadriceps strength measurements in the operative leg and the nonoperative leg were not significantly different between the groups (p = 0.513 and p = 0.523, respectively). The PENG block may have similar analgesic efficacy to the supra-inguinal FICB. No difference was detected in the quadriceps strength between the patients receiving these two blocks.

Preoperative pericapsular nerve group (PENG) block for total hip arthroplasty: a randomized, placebo-controlled trial

BACKGROUND

We hypothesized that the addition of a preoperative pericapsular nerve group (PENG) block to intra-articular local anesthetic injection would improve analgesia after total hip arthroplasty.

METHOD

In this double-blinded trial, 71 patients scheduled for primary total hip arthroplasty were randomized to receive preoperative PENG block with 20 mL 0.5% ropivacaine (PENG group) or 20 mL saline (placebo group). All the patients received an intra-articular injection of 20 mL 0.5% ropivacaine by surgeon after the completion of the procedure. The primary outcome was the highest pain score reported in the recovery room. The secondary outcomes included quadriceps strength, pain scores, opioid use, and opioid-related side effects up to 48 hours after surgery.

RESULTS

Seventy patients were included in the final analysis. The highest visual analog scale in the recovery room showed significant intergroup difference (placebo: 5.2±3.1 vs PENG: 3.3±2.7, p<0.01) but the difference did not persist after discharge from the recovery room. The two groups' postoperative pain scores at rest were similar. A lower intraoperative morphine equivalent dose and lower postoperative vomiting were found in the PENG group. There were no differences in the other outcomes.

CONCLUSION

The addition of a preoperative PENG block to intra-articular injections of local anesthetic provides a limited benefit to postoperative analgesia in the recovery room with no discernible benefits thereafter.

Ultrasound-guided supra-inguinal fascia Iliaca compartment block for older adults admitted to the emergency department with hip fracture: a randomized controlled, double-blind clinical trial

Background

Hip fracture is common in older adults, and can cause severe post-fracture pain. Fascia iliaca nerve block has consequently been used for preoperative analgesia.

Methods

We performed a randomized, controlled, double-blind clinical trial and recruited older patients with hip fractures. These patients were randomized into two groups and received ultrasound-guided fascia iliaca compartment block using either the supra-inguinal approach (group F) or the classical approach (group C). Heart rate, blood pressure, and resting and exercising visual analog scales were recorded before the procedure and at 30 min, and 6, 12, and 24 h after completion of the procedure. We recorded the duration of the procedure—as well as complications such as bleeding, hypotension, and intractable vomiting; the sleep duration in a 24 h period was also documented.

Results

A total of 38 patients completed the trial, and we observed no differences in the baseline characteristics or pre-procedural measurements between the two groups. Compared with the patients in group C, patients in group F exhibited significantly lower exercising VAS scores at 6 and 12 h after the procedure, faster heart rates at 6 and 24 h after the procedure, a longer procedural duration, and a longer sleep duration. There were no differences in the frequencies of complications between the two groups. The percentages of patients who took oral analgesics and the numbers of medications consumed were also not different between the two groups.

Conclusions

The supra-inguinal FICB provided effective analgesia and improved exercise tolerance compared with the classical approach.

Trial registration

The trial was registered at the Chinese Clinical Trial Registry (registration number: ChiCTR2100045644, registration date: 2021 April 20).

Short Communication: Lumbar Plexus Block versus Suprainguinal Fascia Iliaca Block to Provide Analgesia Following Hip and Femur Surgery in Pediatric-Aged Patients - An Analysis of a Case Series

Introduction

For surgical procedures involving the hip and femur, various regional anesthetic techniques may be used to provide analgesia. Although there has been an increase in the use of lumbar plexus block (LPB), the technique may be time consuming and associated with complications. Suprainguinal fascia iliaca compartment block (FICB) is a potentially easier and safer alternative. The current study prospectively compares LPB with suprainguinal FICB.

Methods

This prospective, double-blinded, randomized, study included patients undergoing elective orthopedic procedures of the hip and/or femur. All study patients received general anesthesia with randomization to either an LPB or suprainguinal FICB using 0.5% ropivacaine with epinephrine and dexamethasone. Postoperative pain control was achieved with intravenous hydromorphone delivered by patient-controlled analgesia with scheduled acetaminophen and ketorolac. Outcome data included time to perform the block, perioperative opioid consumption, postoperative pain scores (VAS) and hospital length of stay.

Results

The study cohort included 15 patients between the ages of 7 and 16 years (LPB N = 7, FICB N = 8). The median block time was 6 minutes (IQR: 4.11) for the LPB group and 3 minutes (IQR: 3.6) for the FICB group (p = 0.107). Median postoperative pain scores were 4 (IQR: 0.6) for the LPB group and 2 (IQR: 0.5) for the FICB group (p = 0.032). There were no differences in the intraoperative or postoperative opioid and NSAID use between the two groups.

Discussion

The suprainguinal FICB provides analgesia that is at least as effective as a LPB following hip and femur surgery. Time to perform the block was shorter with the FICB due to the supine patient position and limited needle trajectory. Although we noted no adverse effects, the superficial needle trajectory of the FICB offers a less invasive approach and the potential for decreased risks of adverse effects.

Comparison of supra-inguinal fascia iliaca versus pericapsular nerve block for ease of positioning during spinal anaesthesia: A randomised double-blinded trial

Background and Aims

Regional analgesic techniques such as supra-inguinal fascia-iliaca compartment block (S-FICB) and pericapsular nerve group (PENG) block have been found to be effective in providing good pain relief in hip-fracture patients. However, comparative studies between PENG and S-FICB are lacking. The aim of this study was to compare the analgesic efficacy of S-FICB and PENG block and assess their efficacy in optimal patient positioning for spinal anaesthesia.

Methods

A prospective randomised double-blind study was conducted in 66 patients randomly divided to receive either S-FICB or PENG block under ultrasound guidance. Primary outcome measures were numerical rating scale (NRS) pain score at rest and on passive 15° limb lifting, 30 minutes after the block and ease of spinal positioning. The secondary outcome measures were NRS over 24 hours, amount of tramadol used (number of rescue doses), patients' satisfaction and block-related complications. The results were analysed using statistical software (MedCalc version 19.2.1). Continuous and categorical data were analysed using appropriate statistical analysis and P < 0.05 was considered significant.

Results

Post-block, the NRS score decreased significantly in PENG and S-FICB groups at rest and movement (P < 0.0001). The EOSP score was significantly better in PENG group (P < 0.0001). First analgesic request and pain relief in the first 24-hour period were similar between the groups (P = 0.524).

Conclusion

PENG block provided better pain relief and ease of positing during SA in patients with fractured hip scheduled for hip surgery.

Combined fascia iliaca compartment block and monitored anesthesia care for geriatric patients with hip fracture: Two case reports

BACKGROUND

Major hip surgery usually requires neuraxial or general anesthesia with tracheal intubation and may be supplemented with a nerve block to provide intraoperative and postoperative pain relief.

CASE SUMMARY

This report established that hip surgical procedures can be performed with a fascia iliaca compartment block (FICB) and monitored anesthesia care (MAC) while avoiding neuraxial or general anesthesia. This was a preliminary experience with two geriatric patients with hip fracture, American Society of Anesthesiologists status III, and with many comorbidities. Neither patient could be operated on within 48 h after admission. Both general anesthesia and neuraxial anesthesia were high-risk procedures and had contraindications. Hence, we chose nerve block combined with a small amount of sedation. Intraoperative analgesia was provided by single-injection ultrasound-guided FICB. Light intravenous sedation was added. Surgical exposure was satisfactory, and neither patient complained of any symptoms during the procedure.

CONCLUSION

This report showed that hip surgery for geriatric patients can be performed with FICB and MAC, although complications and contraindications are common. The anesthetic program was accompanied by stable respiratory and circulatory system responses and satisfactory analgesia while avoiding the adverse effects and problems associated with either neuraxial or general anesthesia.

A review of evidence-based clinical practice on fascia iliaca compartment block for lower limb injury

BACKGROUND

The main objective of this study was to resolve fascia iliaca compartment block controversies by putting the currently available evidences applied for knee, femoral shaft, and hip bone injury or related to surgery.

METHODS

The databases PubMed, Cochrane Review, and Google Scholar were searched without regard to language or publication type for fascia iliaca compartment block before December 2020. After eligibility sorting and duplicate removal, a total of 26,609 articles were identified, with 21 of them being included for review.

DISCUSSION

In the emergency department, fascia iliaca compartment block (FICB) has now become the standard of practice. Various evidence suggested that 20-40 ml of local anesthetic was required for an effective block in adult patients.

CONCLUSION

For the knee, femoral bone, and hip region surgery, the fascia iliaca compartment block (FICB) provided better anesthesia quality, reduced systemic morphine consumption, and had fewer complications than epidural anesthesia. Anesthetists and surgical department staff should promote the FICB's benefits by emphasizing its superiority in pain management.

Nuts and Bolts of Peripheral Nerve Blocks for Pain After Hip Fracture for Everyday Anesthetist

A range of peripheral nerve blocks is available to treat hip fracture pain, leaving clinicians confused on choice. No single block appears to be outstanding. The article described the relevant anatomy, technical approach, risk associated, and practicability to facilitate a better understanding of the various approaches available. The clinician should be able to make an informed decision based on local requirements and logistics.

Comparison of the suprainguinal fascia iliaca compartment block with continuous epidural analgesia in patients undergoing hip surgeries: a retrospective study

Background and objective

Pain control is one of the major concerns after major hip surgeries. Suprainguinal fascia iliaca compartment block (S-FICB) is an alternative analgesic technique that can be considered as an effective and less invasive method than epidural analgesia (EA). In this retrospective study, we compared postoperative analgesic efficacy of single shot ultrasound guided S-FICB and EA after major hip surgery.

Methods

We retrospectively examined 150 patients who underwent major hip surgeries and who received S-FICB or EA. Seventy-two patients submitted to EA and 78 patients who received S-FICB were included and their medical records retrospectively reviewed. Morphine consumptions, VAS scores, and side effects were recorded. Patients under antiplatelet or anticoagulant theraphy were also registered. Morphine consumption and VAS scores were the primary endpoints, succes rate and complications were the secondary endpoints of our study. P-values less than 0.05 were considered statistically significant.

Results

Morphine consumption was lower at the emergence in the EA group but there was no statistically significant difference between the two groups according to total opioid consumption (0 [0-0] vs 0 [0-0]; p = 0.52). There was no difference between VAS scores in the first 18 hours. Hypotension was significantly higher in the EA group (9 vs 21; p = 0.04).

Conclusion

In conclusion, S-FICB can provide comparable analgesia with EA in the early postoperative period after hip surgery but VAS scores were found lower in the EA group than S-FICB group after 18^th hour. Hypotension has occured more frequently in patients receiving EA.

Randomized comparison between pericapsular nerve group (PENG) block and suprainguinal fascia iliaca block for total hip arthroplasty

BACKGROUND

This randomized trial compared ultrasound-guided pericapsular nerve group block and suprainguinal fascia iliaca block in patients undergoing primary total hip arthroplasty. We selected the postoperative incidence of quadriceps motor block (defined as paresis or paralysis of knee extension) at 6 hours as the primary outcome. We hypothesized that, compared with suprainguinal fascia iliaca block, pericapsular nerve group block would decrease its occurrence from 70% to 20%.

METHODS

Forty patients undergoing primary total hip arthroplasty under spinal anesthesia were randomly allocated to receive a pericapsular nerve group block (n=20) using 20 mL of adrenalized levobupivacaine 0.50%, or a suprainguinal fascia iliaca block (n=20) using 40 mL of adrenalized levobupivacaine 0.25%. After the performance of the block, a blinded observer recorded pain scores at 3, 6, 12, 18, 24, 36, and 48 hours; cumulative breakthrough morphine consumption at 24 and 48 hours; opioid-related side effects; ability to perform physiotherapy at 24 and 48 hours; as well as length of stay. Furthermore, the blinded observer also carried out sensory assessment (of the anterior, lateral, and medial aspects of the mid-thigh) and motor assessment (knee extension and hip adduction) at 3, 6, and 24 hours.

RESULTS

Compared with suprainguinal fascia iliaca block, pericapsular nerve group block resulted in a lower incidence of quadriceps motor block at 3 hours (45% vs 90%; p<0.001) and 6 hours (25% vs 85%; p<0.001). Furthermore, pericapsular nerve group block also provided better preservation of hip adduction at 3 hours (p=0.023) as well as decreased sensory block of the anterior, lateral, and medial thighs at all measurement intervals (all p≤0.014). No clinically significant intergroup differences were found in terms of postoperative pain scores, cumulative opioid consumption at 24 and 48 hours, ability to perform physiotherapy, opioid-related side effects, and length of hospital stay.

CONCLUSION

For primary total hip arthroplasty, pericapsular nerve group block results in better preservation of motor function than suprainguinal fascia iliaca block. Additional investigation is required to elucidate the optimal local anesthetic volume for motor-sparing pericapsular nerve group block and to compare the latter with alternate motor-sparing strategies such as periarticular local anesthetic infiltration.

Fascial plane blocks: a narrative review of the literature

Fascial plane blocks (FPBs) are increasingly numerous and are often touted as effective solutions to many perioperative challenges facing anesthesiologists. As 'new' FPBs are being described, questions regarding their effectiveness remain unanswered as appropriate studies are lacking and publications are often limited to case discussions or technical reports. It is often unclear if newly named FPBs truly represent a novel intervention with new indications, or if these new publications describe mere ultrasound facilitated modifications of existing techniques. Here, we present broad concepts and potential mechanisms of FPB. In addition, we discuss major FPBs of (1) the extremities (2) the posterior torso and (3) the anterior torso. The characteristics, indications and a brief summary of the literature on these blocks is included. Finally, we provide an estimate of the overall level of evidence currently supporting individual approaches as FPBs continue to rapidly evolve.

Postoperative pain treatment with transmuscular quadratus lumborum block and fascia iliaca compartment block in patients undergoing total hip arthroplasty: a randomized controlled trial

Background

Patients often suffer moderate or even severe pain after total hip arthroplasty; such pain seriously affects early postoperative recovery. This study aimed to investigate the analgesic efficacy of ultrasound-guided transmuscular quadratus lumborum block combined with fascia iliaca compartment block for elderly patients undergoing total hip arthroplasty.

Methods

Fifty-four patients scheduled for total hip arthroplasty were included in this randomized controlled study. The patients were randomly assigned to receive only transmuscular quadratus lumborum block (group Q) or transmuscular quadratus lumborum block combined with fascia iliaca compartment block (group QF) with ultrasound guidance. Postoperatively in both groups, paracetamol 1 g was regularly administered at 6 h intervals and patient-controlled intravenous analgesia was administered. The primary outcome was cumulative sufentanil consumption via patient-controlled intravenous analgesia 24 h postoperatively. The secondary outcomes included pain degree, time to the first analgesic requirement, joint range of motion, quality of recovery, and the incidence of postoperative complications.

Results

Fifty patients were included, and their data were analyzed. The cumulative sufentanil consumption in group QF was significantly lower during the first 24 h after surgery than that in group Q, and the cumulative sufentanil consumption in group QF was reduced at 6–12 and 12–18 h after surgery. The postoperative pain intensity was lower in group QF than in group Q (linear mixed-effects model, the main effect of treatment: P < 0.001). Compared with group Q, group QF had higher quality of recovery and joint range of movement. The time to the first analgesic requirement was longer in group QF than in group Q (log-rank, P < 0.001). There was no statistically significant difference in complications postoperatively between the two groups.

Conclusions

Our study provides a multimodal, opioid-sparing analgesic regimen for elderly patients undergoing total hip arthroplasty. The combination of transmuscular quadratus lumborum block and fascia iliaca compartment block provides a significant advantage for early postoperative functional recovery. Further studies are required to confirm the minimum effective dose.

Trial registration

The study was registered on the 21st December 2020 (retrospectively registered) on the Chinese Clinical Trial Registry: ChiCTR2000038686.

The effect of fascia iliaca block on postoperative pain and analgesic consumption for patients undergoing primary total hip arthroplasty: a meta-analysis of randomized controlled trials

Background

The primary aim of this systematic review and meta-analysis was to compare postoperative pain, analgesic consumption, and complications after fascia iliaca block (FIB) versus control for patients undergoing primary total hip arthroplasty (THA). Second, we compared the outcomes of FIB versus placebo. Finally, we sought to evaluate pain and analgesic consumption after preoperative and postoperative FIB.

Methods

We performed a systematic literature search in MEDLINE, Embase, Scopus, Web of Science, Google Scholar, ClinicalTrials.gov, and CENTRAL through February 2021 to identify randomized controlled trials (RCTs) that evaluated the efficacy of FIB versus control for patients undergoing primary THA. All analyses were conducted on intent-to-treat data with a random-effects model.

Results

Twelve RCTs with a total of 815 patients were included. There was no difference in postoperative pain (P = 0.64), analgesic consumption (P = 0.14), or complication rate (P = 0.99) between FIB and control groups. Moreover, no difference in postoperative pain (P = 0.26), analgesic consumption (P = 0.06), or complication rate (P = 0.71) was found between FIB and placebo. Moreover, sensitivity analysis suggested that no significant difference in postoperative pain, analgesic consumption, or complication rate was present between FIB and control in studies that used preoperative and postoperative FIB.

Conclusion

FIB was not found to be superior to placebo or various anesthetic techniques for patients undergoing primary THA, as measured by postoperative pain, analgesic consumption, and complications.

Ultrasound-Guided Suprainguinal Fascia Iliaca Compartment Block for Postoperative Analgesia in Patients Undergoing Hip and Femur Surgeries: A Retrospective Analysis

Context:

Fractures of femur and hip surgeries pose a challenge because of excruciating pain. Fascia iliaca compartment block is an effective and easily learned procedure to decrease postoperative pain score and dosage of opioid. Many adjuvants are combined with local anesthetics to prolong the postoperative analgesia.

Aims:

The aim was to study duration of postoperative analgesia in terms of Numeric Rating Scale (NRS), number of times rescue analgesic used, any adverse effect, and patient satisfaction score.

Settings and Design:

Operation theatre of Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow.

Materials and Methods:

The present study was retrospective study with 203 patients evaluated. Based on the combination of the anesthesia and drugs, study patients were divided into six groups. Pain scores were assessed at 6 hourly intervals for 24 h.

Statistical Analysis Used:

Kruskal–Wallis H-test used to compare NRS as well as age and duration of anesthesia. Chi-square test/Fisher's exact test used to compare the proportions.

Results:

Postoperative analgesia was comparable and insignificant (P > 0.05) at 0, 6, 12 h in all six groups. Better postoperative analgesia was observed with dexmedetomidine and dexamethasone as adjuvant at 18 h, dexmedetomidine as adjuvant in comparison to dexamethasone as adjuvant at 24 h. Rescue analgesia in postoperative period was required maximum in plain bupivacaine. Satisfaction levels were good and excellent in dexmedetomidine and dexamethasone as adjuvant.

Conclusions:

Addition of dexmedetomidine to bupivacaine provides longer duration, good quality postoperative analgesia, reduced requirement for rescue analgesic, lesser postoperative nausea and vomiting, and better satisfaction levels.

Ultrasound-guided, direct suprainguinal injection for fascia iliaca block for total hip arthroplasty: A retrospective study

BACKGROUND

Peripheral regional block combined with general anesthesia might be a preferable anesthetic regimen for elderly patients undergoing total hip arthroplasty.

AIM

To investigate whether ultrasound-guided, direct suprainguinal injection for fascia iliaca block accelerated recovery after general anesthesia and relieved postoperative pain after total hip arthroplasty.

METHODS

Patients who underwent total hip arthroplasty under general anesthesia in 2015 or 2019 at The Second Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. The patients were grouped based on whether preoperative suprainguinal fascia iliaca block was performed or not. The time to tracheal extubation and time spent in the post-anesthesia care unit (PACU), intraoperative remifentanil dosage, fentanyl consumption in the PACU, postoperative cumulative fentanyl consumption within 48 h after operation, visual analogue scale at rest and during movement on the first and second days after surgery, and adverse reactions were compared.

RESULTS

Thirty-one elderly patients who underwent total hip arthroplasty were included in the study (block group, n = 16; no-block group, n = 15). The visual analog scale scores at rest and during movement on the first and second days were significantly lower in the block group than in the no-block group (all P < 0.05). Compared with the no-block group, the intraoperative remifentanil dosage was lower, the time to tracheal extubation and the time spent in the PACU were shorter in the block group (all P < 0.01). Fentanyl consumption in the PACU and postoperative cumulative fentanyl consumption in 48 h after operation were lower in the block group (all P < 0.01). The incidence of dizziness was higher in the no-block group than in the block group (P = 0.037).

CONCLUSION

Ultrasound-guided, direct suprainguinal injection for fascia iliaca block led to faster recovery after general anesthesia and early postoperative pain relief in elderly patients undergoing total hip arthroplasty.

PROSPECT guideline for total hip arthroplasty: a systematic review and procedure-specific postoperative pain management recommendations

The aim of this systematic review was to develop recommendations for the management of postoperative pain after primary elective total hip arthroplasty, updating the previous procedure-specific postoperative pain management (PROSPECT) guidelines published in 2005 and updated in July 2010. Randomised controlled trials and meta-analyses published between July 2010 and December 2019 assessing postoperative pain using analgesic, anaesthetic, surgical or other interventions were identified from MEDLINE, Embase and Cochrane databases. Five hundred and twenty studies were initially identified, of which 108 randomised trials and 21 meta-analyses met the inclusion criteria. Peri-operative interventions that improved postoperative pain include: paracetamol; cyclo-oxygenase-2-selective inhibitors; non-steroidal anti-inflammatory drugs; and intravenous dexamethasone. In addition, peripheral nerve blocks (femoral nerve block; lumbar plexus block; fascia iliaca block), single-shot local infiltration analgesia, intrathecal morphine and epidural analgesia also improved pain. Limited or inconsistent evidence was found for all other approaches evaluated. Surgical and anaesthetic techniques appear to have a minor impact on postoperative pain, and thus their choice should be based on criteria other than pain. In summary, the analgesic regimen for total hip arthroplasty should include pre-operative or intra-operative paracetamol and cyclo-oxygenase-2-selective inhibitors or non-steroidal anti-inflammatory drugs, continued postoperatively with opioids used as rescue analgesics. In addition, intra-operative intravenous dexamethasone 8-10 mg is recommended. Regional analgesic techniques such as fascia iliaca block or local infiltration analgesia are recommended, especially if there are contra-indications to basic analgesics and/or in patients with high expected postoperative pain. Epidural analgesia, femoral nerve block, lumbar plexus block and gabapentinoid administration are not recommended as the adverse effects outweigh the benefits. Although intrathecal morphine 0.1 mg can be used, the PROSPECT group emphasises the risks and side-effects associated with its use and provides evidence that adequate analgesia may be achieved with basic analgesics and regional techniques without intrathecal morphine.

Effectiveness of Fascia Iliaca Compartment Block after Elective Total Hip Replacement: A Prospective, Randomized, Controlled Study

Objective: An assessment of the feasibility of fascia iliaca compartment block (FICB) combined with nonopioid analgesics and patient controlled analgesia (PCA), oxycodone, in the perioperative anaesthetic management for elective total hip replacement (THR). Design: A randomised, single-center, open-label study. Setting: A single hospital. The study was conducted from October 2018 to May 2019. Participants: In total, 109 patients were scheduled for elective total hip replacement. Interventions: Postoperative FICB with 0.375% ropivacaine in conjunction with nonopioid analgesics (paracetamol, metamizole, and pregabalin) and oxycodone as rescue analgesia. Measurements: Pain intensity was measured using the Numeric Pain Rating Scale (NRS) at rest and during rehabilitation, the total dose of postoperative oxycodone required, the occurrence of opioid-related adverse events, patient hospitalisation time, and level of satisfaction. Follow-up period: 48 h. Main Results: A total of 109 patients were randomised into two groups and, of these, 9 were subsequently excluded from the analysis (three conversions to general anaesthesia, two failures to perform FICB, four failures to use the PCA pump). Patients in the FICB group received standard intravenous analgesia with FICB, and those in the control group were managed with standard intravenous analgesia only. Pain level measured with NRS was significantly lower at rest and during rehabilitation in the FICB group. Oxycodone use in the first 48 h was significantly higher in the control group (p < 0.001); additionally, the time to the first dose of rescue analgesia was significantly shorter (p < 0.001). In the control group, there was a higher rate of side effects and a significantly longer hospitalisation time (p < 0.001). Similarly, higher satisfaction with the applied analgesic treatment was noted in the FICB group. Conclusions: FICB in elective THR treatments is an effective form of analgesia, which reduces the need for opioids, the number of complications, the length of hospitalisation, and which ensures a high level of patient satisfaction with the analgesic treatment used.

Cadaveric investigation of the minimum effective volume for ultrasound-guided suprainguinal fascia iliaca block

BACKGROUND

This cadaveric dose-finding study investigated the minimum effective volume of dye in 90% of cases (MEV90), required to stain the femoral, lateral femoral cutaneous and obturator nerves for ultrasound-guided suprainguinal fascia iliaca block (SIFIB).

METHODS

In cadaveric specimens of the lower limb, the block needle was advanced, medial to the anterosuperior iliac spine, until its tip was positioned between the internal oblique and iliacus muscles underneath the fascia iliaca. The dye was injected inside the fascia iliaca compartment. Volume assignment was carried out using a biased coin design, whereby the volume of dye administered to each cadaveric specimen depended on the response of the previous one. In case of failure, the next one received a higher volume (defined as the previous volume with an increment of 2.5 mL). If the previous cadaveric specimen had a successful block, the next one was randomized to a lower volume (defined as the previous volume with a decrement of 2.5 mL), with a probability of b=0.11, or the same volume, with a probability of 1-b=0.89. Success was defined as the staining of the femoral, lateral femoral cutaneous, and obturator nerves on dissection.

RESULTS

Thirty-six cadavers (60 cadaveric specimens) were included in the study. Using isotonic regression and bootstrap CI, the MEV90 for ultrasound-guided SIFIB was estimated to be 62.5 mL (95% CI 60 to 65).

CONCLUSION

For ultrasound-guided SIFIB, the MEV90 of dye required to stain the femoral, lateral femoral cutaneous and obturator nerves is 62.5 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in human subjects.

Anatomical considerations for obturator nerve block with fascia iliaca compartment block

This report reviews the topographical and functional anatomy relevant for assessing whether or not the obturator nerve (ON) can be anesthetized using a fascia iliaca compartment (FIC) block. The ON does not cross the FIC. This means that the ON would only be blocked by an FIC block if the injectate spreads to the ON outside of the FIC. Such a phenomena would require the creation of one or more artificial passageways to the ON in the retro-psoas compartment or the retroperitoneal compartment by disrupting the normal anatomical integrity of the FI. Due to this requirement for an artificial pathway, an FIC block probably does not block the ON.

Transmuscular Quadratus Lumborum Block versus Suprainguinal Fascia Iliaca Block for Hip Arthroplasty: A Randomized, Controlled Pilot Study

Background

This study aimed to investigate the analgesic efficacy and motor block profile of single-shot transmuscular quadratus lumborum block (QLB) in comparison with those of suprainguinal fascia iliaca block (FIB) in patients undergoing hip arthroplasty.

Methods

This randomized, double-blinded, controlled trial included adult patients undergoing hip arthroplasty under spinal anesthesia. Patients were allocated to one of two groups according to the regional block received: FIB group (n=19) or QLB group (n=17). Both study groups were compared with regard to the duration of analgesia (primary outcome), block performance time, pain during positioning for spinal anesthesia, total morphine consumption in the first postoperative 24-h period, quadriceps muscle power, and static and dynamic visual analog scale.

Results

Thirty-six patients were included in the final analysis. Both study groups had comparable durations of analgesia. Postoperative visual analog scale (static and dynamic) values were comparable between the two groups in most readings. The block performance time was shorter in the FIB group. The number of patients with pain during positioning for the subarachnoid block was lower in the QLB group. The total morphine requirement during the first 24 h was marginally lower in the FIB group, whereas the quadriceps motor grade was higher in the FIB group than in the QLB group at 4 h and 6 h after surgery.

Conclusion

Both single-shot blocks, namely the suprainguinal FIB and transmuscular QLB, provide effective postoperative analgesia after hip arthroplasty. FIB showed slightly lower 24-h morphine consumption, while QLB showed better quadriceps motor power.

Clinical Trial Registration

The study was registered at clinical trials registry system before enrollment of the first participant (NCT04005326; initial release date, 2 July 2019; https://clinicaltrials.gov/ct2/show/NCT04005326).

Skin temperature changes after ultrasound-guided supra-inguinal fascia iliaca block: a prospective observational study

PURPOSE

Ultrasound-guided supra-inguinal fascia iliaca block (SFIB) is widely used as regional anesthesia of the hip and thigh. It is difficult to judge the blocking effect and the spreading local anesthesia. We hypothesize that the effect and spread of the block could be proven objectively by a rise in the temperature. In this prospective observational study, the broad regional rise in skin temperature of twenty patients who were scheduled for hip surgery was measured using an infrared thermographic camera at multiple intervals following ultrasound-guided SFIB.

METHODS

Infrared thermographic imaging of skin temperature at the femoral, obturator, and lateral femoral cutaneous nerve sites was performed before and at 5-min intervals after ultrasound-guided SFIB for up to 15-min post-injection. The primary outcomes are skin surface temperature. Sensory block was assessed immediately after the final infrared thermographic image acquisition using the cold test.

RESULTS

Compared to pre-injection baseline, temperature increased by 1.2 °C [95% confidence interval (CI) 0.4-2.0 °C] after 5 min, 1.2 °C (95% CI 0.4-2.0 °C) after 10 min, and 0.9 °C (95% CI 0.4-2.1°C) after 15 min. The cold test response was reduced in all cases at the femoral and lateral femoral cutaneous nerve sites and in 13 cases at the obturator nerve site. The sensitivity and specificity of the temperature increase to cold loss were 96% and 63%, respectively when we defined >0°C as the clinical threshold.

CONCLUSIONS

Successful SFIB significantly enhanced skin temperature at the hip and thigh in all cases, suggesting that infrared surface thermography can be used as an objective assessment tool for adequate analgesia.

The Application of Fascia Iliaca Compartment Block for Acute Pain Control of Hip Fracture and Surgery

PURPOSE OF REVIEW

Over 300,000 patients are hospitalized annually following hip fractures in the USA. Many patients experienced inadequate analgesia. We will review the perioperative effects of the fascia iliaca compartment block (FICB) in hip fracture patients.

RECENT FINDINGS

FICB by injecting local anesthetics beneath the fascia iliaca results in significant pain relief in hip fractures. Neuropathies and vascular injuries are almost unlikely. Single-shot FICB is faster to place, yet providing about 8 h of analgesia when bupivacaine is used. Continuous FICB provides prolonged titratable analgesia, improved patient satisfaction, and leads to faster hospital discharge. FICB reduces opioid consumption, decreases morbidity and mortality, reduces hospital stay, reduces delirium, and improves satisfaction. FICB should form part of a multimodal analgesic regime, in the context of a multidisciplinary approach to the management of hip fracture patients. More clinical investigations are needed to validate the long-term outcome benefits of FICB in hip fracture patients.

Improvement of analgesic efficacy for total hip arthroplasty by a modified ultrasound-guided supra-inguinal fascia iliaca compartment block

Background

Fascia iliaca compartment block (FICB) is an anterior approach to the lumbar plexus block and provides the effective adjunctive analgesia for total hip arthroplasty (THA).

Methods

As a case series study, 28 patients (≥ 65 years old) with THA were received a modified in-plane ultrasound-guided supra-inguinal (S-FICB) as an analgesic adjunct to evaluate the analgesic effectiveness and the local anesthetic diffusion with magnetic resonance imaging (MRI). A combination of propofol and sufentanil was administered to conduct target-controlled infusion.

Results

The pain scores were 1 (0–4), 2 (1–5), 3 (1–6) and 3 (1–6) at 4, 8, 12, and 24 h. The cumulative opioids were 8 (8–12), 18 (16–32), 28 (24–54) and 66 (48–104) mg of i.v. morphine equivalents at 4, 8, 12, and 24 h. The patient-controlled analgesia (PCA) times were 0 (0–1), 1 (0–2), 2 (0–5) and 5 (3–8) at 4, 8, 12, and 24 h. In lateral, anterior and medial part of thigh, the sensory blockade in 28 patients was 23 (82 %), 21 (75 %) and 19 (68 %) at 5 min; 28 (100 %) at 10 and 20 min. Motor blockade of femoral nerve (FN) and obturator nerve (ON) was present in 13 (46 %) and 3 (11 %) patients at 5 min, 24 (86 %) and 9 (32 %) at 10 min, 26 (93 %) and 11 (39 %) at 20 min. Injectate permeated to the FN and extended superiorly over the surface of iliac muscle (IM) and pectineus muscle (PM) in all patients.

Conclusions

The modified S-FICB has provided an effective postoperative analgesic adjunct after THA with the satisfactory blockade of femoral (FN), obturator (ON) and sciatic (SN) nerves, especially for ON, when compared with the existing techniques.

Continuous pericapsular nerve group block for postoperative pain management in total hip arthroplasty: report of two cases

BACKGROUND

Total hip arthroplasty (THA) is one of the surgical procedures associated with severe postoperative pain. Appropriate postoperative pain management is effective for promoting early ambulation and reducing the length of hospital stay. Effects of conventional pain management strategies, such as femoral nerve block and fascia iliaca block, are inadequate in some cases.

CASE PRESENTATION

THA was planned for 2 patients with osteoarthritis. In addition to general anesthesia, continuous pericapsular nerve group (PENG) block and lateral femoral cutaneous nerve (LFCN) block were performed for postoperative pain management. Numerical rating scale (NRS) scores measured at rest and upon movement were low at 2, 12, 24, and 48 h postoperatively, suggesting that the treatments were effective for managing postoperative pain. The Bromage score at postoperative days (POD) 1 and 2 was 0.

CONCLUSION

Continuous PENG block and LFCN block were effective for postoperative pain management in patients who underwent THA. PENG block did not cause postoperative motor blockade.

Minimum effective volume of ropivacaine for ultrasound-guided supra-inguinal fascia iliaca compartment block

Supra inguinal fascia iliaca compartment block (FICB) is increasingly used in elderly patients with hip fractures. However, the minimum effective volume of local anesthetics required for ultrasound-guided supra-inguinal FICB has not been determined. With ethical committee approval and written informed consent from patients, we studied 21 consecutive patients of ASA physical status I–III undergoing surgery for hip fracture who met the inclusion criteria. Blocks were performed before going to the operation room. We determined the injection volumes of 0.25% ropivacaine for consecutive patients from the preceding patient's outcome. The initial volume was 30 ml. The testing interval was set at 10 ml, and the lowest volume was 5 ml. An effective block was defined as loss of sensation of pinprick in the territory of the femoral nerve and lateral cutaneous nerve of the thigh 30 min after the injection. The aim of this study was to determine the 50% effective volume (EV₅₀) and the 95% effective volume (EV₉₅) of 0.25% ropivacaine for ultrasound-guided supra-inguinal FICB using Logistic regression analysis. EV₅₀ and EV₉₅ of 0.25% ropivacaine for ultrasound-guided supra-inguinal FICB calculated with logistic regression analysis were 15.01 ml (95% confidence interval, 6.53–22.99 ml) and 26.99 ml (95% confidence interval, 20.54–84.09 ml), respectively. EV₅₀ and EV₉₅ of 0.25% ropivacaine for ultrasound-guided supra-inguinal FICB were 15.01 ml and 26.99 ml, respectively.

Comparison of the Effectiveness of Suprainguinal Fascia Iliaca Compartment Block and Patient-Controlled Analgesia for Major Hip Surgeries in Elderly Patients

OBJECTIVE

Fascia iliaca compartment block is an alternative analgesic technique for hip surgeries. In the new suprainguinal technique, the 'bowtie' sign is detected with an ultrasound probe, and local anaesthetic is injected into the fascial plane with in-plane approach. In this retrospective study, we compared the postoperative analgesic efficacy of suprainguinal fascia iliaca compartment block (S-FICB) and patient-controlled analgesia (PCA) after major hip surgery in elderly patients.

METHODS

We retrospectively recorded visual analogue scale (VAS) scores, morphine consumptions and opioid side effects who underwent either a S-FICB (n=67) or PCA (n=61). In the S-FICB group, 25-40 mL of 0.25% bupivacaine was administered with a single-shot S-FICB technique after induction of anaesthesia. VAS scores during resting (VAS-S) and movement (VAS-D); morphine consumption at 0, 6, 12, 24 and 48 hours; total morphine consumption; and opioid-related complications were recorded.

RESULTS

Morphine consumptions in each measurement period and in total were significantly lower in the S-FICB group (694.03±2,007.47 μg vs. 13,368.85±4,834.68 μg; p<0.05). The total number of opioid-related complications were also significantly lower in the S-FICB group (17/67 vs. 48/62; p<0.05). More than half of the patients (38/67, 56%) did not need morphine administration in the S-FICB group. VAS-S during the first 6 hours and VAS-D up to 24 hours postoperatively were significantly lower in the S-FICB group (p<0.05).

CONCLUSION

In our study, S-FICB provided better analgesia than the PCA technique after hip surgery in elderly patients. Moreover, S-FICB reduced opioid consumption and opioid-related complications in the first 24 hours postoperatively.

Trends in Pediatric Pain: Thinking Beyond Opioids

Trends in pediatric pain management are moving toward thinking beyond opioids. Regional anesthetic techniques, such as quadratus lumborum and erector spinae plane blocks, demonstrate efficacy and safety in pediatric populations. Extremity blocks with motor-sparing characteristics also are used. Adjuvants may be added to pediatric peripheral nerve blocks to increase duration of action and improve block efficacy. For medical management, pediatric pain management frequently uses nonopioid medications. These opioid-sparing medications and regional techniques are used to facilitate enhanced recovery after surgery in pediatric surgical patients. Virtual reality is a field where technology can aid in managing acute pain in pediatric patients.

Ultrasound-guided suprainguinal fascia iliaca block combined with a sacral plexus block for lower extremity surgery: A case report

RATIONALE

The anesthetic management of patients with severe pulmonary hypertension is different from that of normal, healthy patients, and regional nerve blocks are commonly used for them. Due to the individual variability of the course, distribution, and branching of the nerves below the inguinal ligament, the supra-inguinal fascia iliaca (SIFI) block has a wider and more stable blocking area. In combination with the sacral plexus block, they can satisfy the needs of surgical anesthesia below the hip.

PATIENT CONCERNS

A 46-year-old man with tuberculosis, chronic obstructive pulmonary disease, pulmonary heart disease, World Health Organization (WHO) class III pulmonary hypertension and right heart dysfunction, and American Society of Anesthesiologists physical status class III needed fixation of an intramedullary nail in the left lower extremity. Additionally, he had broken his left lower limb after a recent fall. Both general anesthesia and epidural anesthesia were not appropriate.

DIAGNOSES

The patient had a clear history of tuberculosis, computerized tomography scan displayed destructive pneumonophthisis. Furthermore, he had chronic obstructive pulmonary disease and pulmonary heart disease.

INTERVENTIONS

An ultrasound-guided SIFI combined with a sacral plexus block was successfully performed for surgical anesthesia and avoided all hemodynamic fluctuations.

OUTCOMES

We successfully performed an ultrasound-guided SIFI combined with a sacral plexus block for surgical anesthesia and avoided all hemodynamic fluctuations.

LESSONS

Ultrasound-guided suprainguinal fascia iliaca block combined with a sacral plexus block can be suitable for anesthesia for patients with severe circulatory compromise.

Pain Control After Total Hip Arthroplasty: A Randomized Controlled Trial Determining Efficacy of Fascia Iliaca Compartment Blocks in the Immediate Postoperative Period

BACKGROUND

The purpose of this randomized controlled trial is to identify if a fascia iliaca block reduces postoperative pain and narcotic consumption and improves early functional outcomes in primary total hip arthroplasty (THA) performed through the mini-posterior approach.

METHODS

Patients were recruited from September 2017 to September 2019. Eligible patients received a primary THA using a mini-posterior approach with epidural anesthesia. Postoperatively, patients were randomized to receive a fascia iliaca compartment block or a placebo block. Numeric Rating Scale pain scores, narcotic consumption, and functional outcomes were recorded at regular intervals postoperatively.

RESULTS

Upon study completion, 122 patients were available for final analysis. There was no difference in the average pain scores at any time interval between the placebo and block groups during the first 24 hours (P = .21-.99). There was no difference in the morphine equivalents consumed between the groups during any time interval postoperatively (P = .06-.95). Functional testing showed no difference in regards to distance walked during the first therapy session (67.1 vs 68.3 ft., P = .92) and timed-up-and-go testing (63.7 vs 66.3 seconds, P = .86). There was an increased incidence of quadriceps weakness in the block group (22% vs 0%, P = .004) requiring alterations in therapy protocols.

CONCLUSION

This randomized trial shows that a fascia iliaca compartment block does not improve functional performance and does not decrease pain levels or narcotic usage after mini-posterior THA, but does increase the risk of quadriceps weakness postoperatively. Based on these results we do not recommend routine fascia iliaca compartment blocks after THA performed with the mini-posterior approach.

Opioid Use After Discharge Following Primary Unilateral Total Hip Arthroplasty: How Much Are We Overprescribing?

BACKGROUND

The opioid crisis pressures orthopedic surgeons to reduce the amount of narcotics prescribed for postoperative pain management. This study sought to quantify postoperative opioid use after hospital discharge for primary unilateral total hip arthroplasty (THA) patients.

METHODS

A prospective cohort of primary unilateral THA patients were enrolled at a single institution. Detailed pain journals tracked all prescription and over-the-counter pain medication, quantity, frequency, and visual analog scale pain scores. Pain medications were converted to morphine milligram equivalents (MME).

RESULTS

Data from 121 subjects were analyzed; the average visual analog scale pain score was 3.44 while taking narcotics. The average number of days taking narcotics was 8.46 days. The distribution of days taking narcotics was right shifted with 50.5% of patients off narcotics after 1 week, and 82.6% off by 2 weeks postoperatively. The average number of narcotic pills prescribed was significantly greater than narcotic pills taken (72.5 vs 28.8, P < .0001). The average MME prescribed was significantly greater than MME taken (452.1 vs 133.8, P < .0001). The average excess narcotic pills prescribed per patient was 51.7 pills. And 71.9% took fewer than 30 narcotic pills; 90.9% patients took fewer than 50 narcotic pills. Also, 10.7% did not require any narcotics; 9.9% required a refill of narcotics; and 33.1% went home the day of surgery.

CONCLUSION

Significantly more narcotics were prescribed than were taken in the postoperative period following THA with an average 51.7 excess narcotic pills per patient. Adjusting prescribing patterns to match patient narcotic usage could reduce the excess narcotic pills following THA.

Opioid Use After Discharge Following Primary Unilateral Total Knee Arthroplasty: How Much Are We Over-Prescribing?

BACKGROUND

The opioid crisis pressures orthopedic surgeons to reduce the amount of narcotics prescribed for post-operative pain management. This study sought to quantify post-operative opioid use after hospital discharge for primary unilateral total knee arthroplasty (TKA) patients.

METHODS

A prospective cohort of primary unilateral TKA patients performed by one of 5 senior fellowship-trained arthroplasty surgeons were enrolled at a single institution. Detailed pain journals tracked all prescriptions and over-the-counter pain medications, quantities, frequencies, and visual analog scale pain scores. Narcotic and narcotic-like pain medications were converted to morphine milligram equivalents (MME). Statistical analysis was performed using Student's t-test with α < 0.05.

RESULTS

Data from 89 subjects were analyzed; the average visual analog scale pain score was 6.92 while taking narcotics. The average number of days taking narcotics was 16.8 days. The distribution of days taking narcotics was right shifted with 52.8% of patients off narcotics after 2 week, and 74.2% off by 3 weeks post-op. The average MME prescribed was significantly greater than MME taken (866.6 vs 428.2, P < .0001). The average number of narcotic pills prescribed was significantly greater than narcotic pills taken (105.1 vs 52.0, P < .0001). The average excess narcotic pills prescribed per patient was 53.1 pills. About 48.3% took fewer than 40 narcotic pills; 75.3% took fewer than 75 narcotic pills. About 3.4% did not require any narcotics; 40.5% required a refill of narcotics. Also, 9.0% went home the day of surgery.

CONCLUSION

Significantly more narcotics were prescribed than were taken in the post-operative period following TKA with an average 53.1 excess narcotic pills per patient. Adjusting prescribing patterns to match patient narcotic usage could reduce the excess narcotic pills following TKA.

Review of Current Practices of Peripheral Nerve Blocks for Hip Fracture and Surgery

Purpose of Review

This article aims to describe the anatomical and technical aspects of various regional techniques used for fracture hip and hip surgery. We reviewed the commonly used nerve blocks, interfascial plane blocks and current evidence of their utility in hip fracture patients.

Recent Findings

Fascia iliaca compartment block (FICB) and femoral nerve block (FNB) are the most commonly used nerve blocks for providing pain relief for hip fracture patients. Supra-inguinal FICB has more consistent spread to all nerves and can enable better pain control. Both the FICB and FNB have shown analgesic efficacy with reduced pain scores, opioid sparing effect, and they enable better patient positioning for spinal in the operating room. These nerve blocks in the elderly patients can also have beneficial effects on delirium, reduced hospital length of stay, and decreased incidence of pneumonia. Some of the novel interfascial plane blocks like PEricapsular Nerve Group (PENG) blocks are now being explored to provide pain relief for fracture hip.

Summary

Hip fracture in the elderly has associated morbidity and mortality. Early surgical intervention has shown to reduce morbidity and mortality. Pain management in this elderly population poses a unique challenge and complementing with regional anesthesia for analgesia has shown numerous benefits.

Implementation of the Obturator Nerve Block into a Supra-Inguinal Fascia Iliaca Compartment Block Based Analgesia Protocol for Hip Arthroscopy: Retrospective Pre-Post Study

Background and Objectives: The effect of supra-inguinal fascia iliaca compartment block (SI-FICB) in hip arthroscopy is not apparent. It is also controversial whether SI-FICB can block the obturator nerve, which may affect postoperative analgesia after hip arthroscopy. We compared analgesic effects before and after the implementation of obturator nerve block into SI-FICB for hip arthroscopy. Materials and Methods: We retrospectively reviewed medical records of 90 consecutive patients who underwent hip arthroscopy from January 2017 to August 2019. Since August 2018, the analgesic protocol was changed from SI-FICB to SI-FICB with obturator nerve block. According to the analgesic regimen, patients were categorized as group N (no blockade), group F (SI-FICB only), and group FO (SI-FICB with obturator nerve block). Primary outcome was the cumulative opioid consumption at 24 hours after surgery. Additionally, cumulative opioid consumption at 6 and 12 hours after surgery, pain score, additional analgesic requests, intraoperative opioid consumption and hemodynamic stability, and postoperative nausea and vomiting were assessed. Results: Among 87 patients, there were 47 patients in group N, 21 in group F, and 19 in group FO. The cumulative opioid (fentanyl) consumption at 24 hours after surgery was significantly lower in the group FO compared with the group N (N: 678.5 (444.0–890.0) µg; FO: 482.8 (305.8–635.0) µg; p = 0.014), whereas the group F did not show a significant difference (F: 636.0 (426.8–803.0) µg). Conclusion: Our findings suggest that implementing obturator nerve block into SI-FICB can reduce postoperative opioid consumption in hip arthroscopy.

Anterior quadratus lumborum block for postoperative recovery after total hip arthroplasty: a study protocol for a single-center, double-blind, randomized controlled trial

Background

Appropriate pain management is essential to improve the postoperative recovery after total hip arthroplasty (THA). Various case reports have indicated that anterior quadratus lumborum block (QLB) provides effective postoperative analgesia in lower limb surgeries. However, few randomized controlled trials have confirmed the efficacy of anterior QLB for lower limb surgeries. The aim of this single-center, double-blind, randomized controlled trial is to confirm the efficacy of anterior QLB for postoperative recovery after THA.

Methods

The participants will be randomly assigned to either the anterior QLB or placebo groups, using a set of random numbers for the allocation sequence. Only pharmacists will be aware of the allocations; other investigators will be blinded until study completion. After induction of general anesthesia, anterior QLB will be performed by using 0.25% levobupivacaine or normal saline. Fentanyl will be administered according to blood pressure change during the surgery. The primary outcome will be the quality of recovery 40 score (QoR-40). Secondary outcomes will include the visual analog scale score of pain intensity at rest and movement, intraoperative and postoperative doses of fentanyl, and incidence of postoperative nausea and vomiting. Statistical analysis will be performed by using the Student’s t test, Mann–Whitney U test, and Fisher’s exact test as appropriate. A P value of less than 0.05 will be considered statistically significant.

Discussion

The results of our study will reveal whether anterior QLB is effective for postoperative recovery after THA.
