Perioperative Pain Management in Total Hip Arthroplasty: Korean Hip Society Guidelines

Comparison of the effects of two regional anesthetic techniques on pain during high risk hip fracture surgery

OBJECTIVES

In this study, we evaluated perioperative pain management using the Analgesia Nociception Index (ANI) monitoring in high-risk ASA III-IV patients scheduled for hip surgery. Specifically, we examined the lumbar plexus (LP), sacral plexus (SP), and supra-inguinal fascia iliaca compartment blocks (SIFIB), as well as combinations of SP blocks.

METHODS

In this prospective observational study, we included 74 patients who were assigned to one of two groups: Group L, which received LP and SP blocks, and Group F, which received SIFIB and SP blocks. Surgery was performed after confirming the sensory block with the pinprick test and applying the sedation protocol. Sedation levels were evaluated using the BIS monitor whereas analgesic requirements were assessed using the ANI monitor. Demographic data, including age, sex, ASA score, SpO2, heart rate (HR), mean arterial pressure (MAP), duration of sensorimotor block, type and duration of surgery, time to first analgesic use, and total analgesic consumption, were recorded. Visual analog scale (VAS) scores at 0, 6, 12, and 24 h additional analgesic requirements, and satisfaction ratings from patients and surgeons were also evaluated.

RESULTS

Compared to Group F, Group L presented significantly greater ANI values at 30, 60, 90 min intraoperatively, as well as at 6 and 12 h postoperatively. The VAS scores were consistently higher in Group F than in Group L at all measurement times.

CONCLUSION

Group L provided better analgesia, required fewer sedatives during surgery, and had greater satisfaction among patients and surgeons. A negative correlation was found between the VAS score and ANI for assessing patient pain.

[Analgesic effect of "cocktail" analgesia containing high-dose compound betamethasone after revision hip arthroplasty and the use of opioid drugs]

Objective

To investigate the analgesic effect of locally injecting a "cocktail" analgesia containing a high-dose compound betamethasone during revision hip arthroplasty, and also to study the usage of opioid drugs.

Methods

A retrospective analysis was conducted on the clinical data of 180 patients who underwent revision hip arthroplasty due to aseptic loosening of the hip prosthesis between January 2015 and December 2021. Among them, 95 patients received intraoperative injection of "cocktail" analgesia containing high-dose compound betamethasone (group A), and 85 patients received intraoperative injection of traditional "cocktail" analgesia (group B). There was no significant difference in baseline data such as gender, age, body mass index, presence or absence of diabetes mellitus between the two groups ( P>0.05). The hospital stay, use of opioid drugs within 72 hours, and the incidence of adverse reactions within 72 hours after operation [including nausea and vomiting, insomnia, deep venous thrombosis (DVT), infection, etc.] were recorded and compared between the two groups. The pain relief of patients was evaluated using the static and dynamic visual analogue scale (VAS) scores at 12, 24, 48, and 72 hours after operation. The incidence of complications (including prosthesis re-loosening, hip joint dislocation, hip joint stiffness, limping, chronic pain, etc.) at 2 years after operation was recorded, and the Harris Hip Score (HHS) was used to evaluate the function at 2 years after operation.

Results

In group A, the utilization rate of opioid drugs within 72 hours after operation was significantly lower than that in group B ( P<0.05). However, there was no significant difference between the two groups in terms of hospital stay, as well as the incidence of adverse reactions such as nausea and vomiting, insomnia, DVT, and infection within 72 hours after operation ( P>0.05). The VAS scores of both groups decreased with time, and the differences between different time points were significant ( P<0.05). The static and dynamic VAS scores of group A were significantly lower than those of group B at 12, 24, and 48 hours after operation ( P<0.05), but there was no significant difference in static and dynamic VAS scores between the two groups at 72 hours after operation ( P>0.05). All patients in both groups were followed up 2-8 years, with an average of 5.73 years. At 2 years after operation, no significant difference was found between the two groups in the incidence of complications and HHS score ( P>0.05).

Conclusion

"Cocktail" analgesia containing a high-dose compound betamethasone for early analgesia after revision hip arthroplasty can effectively reduce postoperative pain and the use of opioid drugs, but will not increase the incidence of infection and DVT after operation.

Peripheral Nerve Blocks Are Associated With Decreased Early Medical Complications, Dislocations, and Opioid Consumption Following Total Hip Arthroplasty

Background

Peripheral nerve blocks (PNBs) may be utilized for postoperative pain control following total hip arthroplasty (THA). The purpose of this study was to evaluate the association between PNBs and postoperative complication rates, healthcare utilization, and opioid consumption following elective THA.

Methods

Opioid-naive patients who received PNBs on the same day as undergoing THA for degenerative etiologies were identified from a large national database and matched 1:5 to a control cohort using propensity scoring. Rates of medical complications, inpatient readmissions, and emergency department presentations occurring within 90 days of THA and surgery-related complications occurring within 1 year of THA were compared using odds ratios. Total cost and perioperative opioid consumption in morphine milligram equivalents (MMEs) per day were also evaluated and compared between groups.

Results

Propensity score matching resulted in 4748 PNB patients matched to 23,740 control patients. THA patients who received PNBs had lower incidences of deep vein thrombosis (odds ratio [OR] 0.67, P = .004), urinary tract infection (OR 0.76, P < .001), and dislocation (OR 0.51, P < .001). PNBs were also associated with decreased perioperative opioid consumption (38.6 MME/day vs 55.3 MME/day, P < .001). Regarding healthcare utilization, there were no differences between cohorts in rates of inpatient readmission, emergency department presentation, or total cost.

Conclusions

PNBs are associated with decreased risk of deep vein thrombosis, urinary tract infection, and dislocation and decreased perioperative opioid consumption following THA.

Differences in opioid prescriptions by race among U.S. older adults with a hip fracture transitioning to community care

BACKGROUND

Appropriate pain management can facilitate rehabilitation after a hip fracture as patients transition back to the community setting. Differences in opioid prescribing by race may exist during this critical transition period.

METHODS

We conducted a retrospective cohort study of older adult U.S. Medicare beneficiaries with a hip fracture to examine whether the receipt and dose of opioids differs between Black and White patients as they transitioned back to the community setting. We stratified beneficiaries by whether they received institutional post-acute care (PAC). Outcomes were (1) receipt of an opioid and (2) opioid doses in the first 90 days in the community in milligram morphine equivalents (MMEs; also presented in mg oxycodone). We estimated relative rates and risk differences of opioid receipt and dose differences using Poisson and linear regression models, respectively, using the parametric g-formula to standardize for age and sex.

RESULTS

We identified 164,170 older adults with hip fracture (mean age = 82.7 years; 75% female; 72% with PAC; 46% with opioid use after fracture). Overall use of opioids in the community was similar between Black and white beneficiaries. Black beneficiaries had lower average doses in their first 90 days in both total cumulative doses (PAC group: 165 [95% CI -264 to -69] fewer MMEs [-248 mg oxycodone]; no PAC: 167 [95% CI -274 to -62] fewer MMEs [-251 mg oxycodone]) and average MME per days' supply of medication (PAC: -3.0 [-4.6 to -1.4] fewer MMEs per day [-4.5 mg oxycodone]; no PAC: -4.7 [-4.6 to -1.4] fewer MMEs per day [-7.1 mg oxycodone]). In secondary analyses, Asian beneficiaries experienced the greatest differences (e.g., 617-653 fewer cumulative mg oxycodone).

CONCLUSION

Racial differences exist in pain management for Medicare beneficiaries after a hip fracture. Future work should examine whether these differences result in disparities in short- and long-term health outcomes.

Recovery of Muscular Strength Following Total Hip Replacement: A Narrative Review

This narrative review analyzes muscle strength recovery following total hip replacement (THR) and looks at various factors affecting postoperative muscle function restoration. The review synthesizes evidence from various studies regarding the timing and degree of muscular strength recovery, different rehabilitation protocols, and patient-specific variables such as age, preoperative physical condition, and comorbidities, among others. Overall, it appears that THR is associated with improved hip function and quality of life, but this usually takes a long time due to individualized physical therapy interventions. In addition, postoperative rehabilitation has been found not to exist without any personal factors involved such as age or gender whereby for instance senior citizens have no alternative but to go for THR surgery, making their lower limbs weaker than those who are younger. Based on the findings in this review on muscle recovery after THR surgeries, one may conclude that this endeavor should begin as early as possible and include regular resistance training programs with performance-focused functional training after surgery. In addition, more longitudinal studies should be conducted regarding post-surgical outcomes comparing other traditional medical practices.

Comparative Review of Postoperative Analgesic Use After Total Hip Replacement: Opioids Versus Non-opioids

Total hip replacement (THR) is a common surgical procedure aimed at alleviating pain and improving function in patients with hip joint pathology. Effective postoperative pain management is crucial for patient recovery, satisfaction, and overall outcomes. This narrative review examines the comparative efficacy, safety, and implications of using opioids versus non-opioid analgesics in managing postoperative pain following THR. Opioids, while effective for severe pain, pose significant risks such as addiction, tolerance, and adverse effects. Non-opioid analgesics, including non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, and regional anesthesia techniques, offer alternatives with potentially fewer side effects. This review synthesizes current evidence from clinical trials, observational studies, and expert guidelines to provide a comprehensive understanding of the benefits and drawbacks of each analgesic approach. The goal is to inform clinical decision-making and optimize pain management strategies for THR patients, balancing efficacy and safety.

Bilateral pericapsular end nerve blocks for steroid-induced avascular necrosis following COVID-19 infection requiring bilateral total hip replacement

BACKGROUND

Osteonecrosis or avascular necrosis (AVN) of the hip was one of the dreaded complications of coronavirus disease 2019 (COVID-19), which emerged in patients who received steroid therapy. Corticosteroids have been a mainstay in the treatment protocol of COVID-19 patients. Popular corticosteroid drugs used in patients suffering from COVID-19 were intravenous (IV) or oral dexamethasone, methylprednisolone or hydrocortisone. The use of such high doses of corticosteroids has shown very positive results and has been lifesaving in many cases. Still, long-term consequences were drug-induced diabetes, osteoporosis, Cushing syndrome, muscle wasting, peripheral fat mobilization, AVN, hirsutism, sleep disturbances and poor wound healing. A significant number of young patients were admitted for bilateral total hip replacements (THR) secondary to AVN following steroid use for COVID-19 treatment.

AIM

To assess the efficacy of bilateral pericapsular end nerve group (PENG) blocks in patients posted for bilateral THR post-steroid therapy after COVID-19 infection and assess the time taken to first ambulate after surgery.

METHODS

This prospective observational study was conducted between January 2023 and August 2023 at Care Hospitals, Hyderabad, India. Twenty young patients 30-35 years of age who underwent bilateral THR were studied after due consent over 8 months. All the patients received spinal anaesthesia for surgery and bilateral PENG blocks for postoperative analgesia.

RESULTS

The duration of surgery was 2.5 h on average. Seventeen out of twenty patients (85%) had a Visual Analog Score (VAS) of less than 2 and did not require any supplementation. One patient was removed from the study, as he required re-exploration. The remaining two patients had a VAS of more than 8 and received IV morphine post-operatively as a rescue analgesic drug. Fifteen out of seventeen patients (88.2%) could be mobilized 12 h after the procedure.

CONCLUSION

Osteonecrosis or AVN of the hip was one of the dreaded complications of COVID-19, which surfaced in patients who received steroid therapy requiring surgical intervention. Bilateral PENG block is an effective technique to provide post-operative analgesia resulting in early mobilization and enhanced recovery after surgery.

Pain Management for Periacetabular Osteotomy: A Systematic Review

Background

Early post-operative pain control is essential to facilitate rapid recovery after orthopaedic surgery. Despite periacetabular osteotomy (PAO) being the gold standard treatment of prearthritic hip dysplasia, there is limited evidence assessing efficacy of early post-operative pain management strategies. Recent literature has focused on non-opioid supplemental treatments such as nerve blocks or local wound infiltration. The purpose of this systematic review was to assess efficacy of these interventions to reduce pain, facilitate mobilization, reduce length of stay after PAO surgery.

Methods

A systematic review was created under the guidance of PRISMA from databases that included PubMed, OVID Medline, Embase, SCOPUS, Cochrane Central Register of Clinical Trials, and clinicaltrials.gov from their creation dates to 12/21/23. These studies were screen based on predetermined inclusion and exclusion criteria.

Results

A total of six studies were included in this analysis from independent institutions. Three investigated nerve blocks (fascia iliaca, pericapsular, transversus abdominis), one investigated local wound infiltration with ropivacaine, one investigated high-dose dexamethasone, and the last investigated removal of the epidural catheter on postoperative (POD) 1 compared to POD 2. There were heterogeneous outcomes that were measured from these studies. In general, nerve blocks decreased opioid use, pain, and length of hospital stay. The local wound infiltration decreased pain on POD 3 and 4. Removing the epidural catheter on POD1 compared to POD 2 decreased pain and length of stay. High-dose dexamethasone use decreased opioid use on POD 1, otherwise, there was no difference in pain.

Conclusion

In summary, supplemental pain management strategies peri-operatively for PAO surgery can decrease pain, opioid use, and length of hospital stay, though there are few studies assessing these interventions. Limiting opioid use after surgery reduces known negative consequences of the medication and facilitates rapid recovery. Clinical trials are needed that assess efficacy of supplemental pain management strategies after PAO surgery. Level of Evidence: II.

Improved perioperative narcotic usage patterns in patients undergoing robotic-assisted compared to manual total hip arthroplasty

BACKGROUND

Robot-assisted total hip arthroplasty (RA-THA) improves accuracy in achieving the planned acetabular cup positioning compared to conventional manual THA (mTHA), but optimal dosage for peri-RA-THA and mTHA pain relief remains unclear. This study aimed to compare pain control with opioids between patients undergoing direct anterior approach THA with the use of a novel, fluoroscopic-assisted RA-THA system compared to opioid consumption associated with fluoroscopic-assisted, manual technique.

METHODS

Retrospective cohort analysis was performed on a consecutive series of patients who received mTHA and fluoroscopy-based RA-THA. The average amount of postoperative narcotics in morphine milligram equivalents (MME) given to each cohort was compared, including during the in-hospital and post-discharge periods. Analyses were performed on the overall cohort, as well as stratified by opioid-naïve and opioid-tolerant patients.

RESULTS

The RA-THA cohort had significantly lower total postoperative narcotic use compared to the mTHA cohort (103.7 vs. 127.8 MME; P < 0.05). This difference was similarly seen amongst opioid-tolerant patients (123.6 vs. 181.3 MME; P < 0.05). The RA-THA cohort had lower total in-hospital narcotics use compared to the mTHA cohort (42.3 vs. 66.4 MME; P < 0.05), consistent across opioid-naïve and opioid-tolerant patients. No differences were seen in post-discharge opioid use between groups.

CONCLUSIONS

Fluoroscopy-based RA-THA is associated with lower postoperative opioid use, including during the immediate perioperative period, when compared to manual techniques. This may have importance in rapid recovery protocols and mitigating episode burden of care.

Effectiveness of Intravenous Non-Opioid Analgesics for Postoperative Pain Management of in Patients Undergoing Hip Surgery: A Systematic Review and Meta-Analysis

Background and Objectives: Intravenous (IV) non-opioid analgesics (NOAs) have been extensively investigated as a multimodal analgesic strategy for the management of acute pain after hip surgery. This pair-wise meta-analysis examined IV NOA effects following hip surgery. Materials and Methods: A systematic search of the MEDLINE (PUBMED), Embase, and Cochrane Library databases was performed for studies investigating the effect of IV NOA for postoperative pain management following hip surgery up to 7 June 2023. We compared in-admission opioid use, postoperative VAS (visual analogue scale) score, hospital stay duration, and opioid-related adverse events between IV NOA and control groups. Results: Seven studies were included with a total of 953 patients who underwent hip surgery. Of these, 478 underwent IV NOA treatment, and 475 did not. The IV NOA groups had lower opioid use within 24-h following hip surgery (SMD, -0.48; 95% CI, -0.66 to -0.30; p < 0.01), lower VAS score (SMD, -0.47; 95% CI, -0.79 to -0.16; p < 0.01), shorter hospital stay (SMD, -0.28; 95% CI, -0.44 to -0.12; p < 0.01), and lower incidence of nausea and vomiting (OR, 0.32; 95% CI, 0.15 to 0.67; p < 0.01) compared with the control groups. Conclusions: This meta-analysis demonstrated that IV NOA administration following hip surgery may have more favorable postoperative outcomes than those in control groups.

Effect of enhanced recovery after surgery nursing on the incidence of surgical site wound infection in older adults with hip fractures: A meta-analysis

This meta-analysis evaluated the effect of enhanced recovery after surgery (ERAS) nursing on the incidence surgical site wound infection in older adults with hip fractures. The PubMed, Embase, the Cochrane Library, Web of Science, China Biomedical Literature Database, Wanfang, China National Knowledge Infrastructure, and VIP databases were searched from inception up to March 2023 for articles on randomized controlled trials (RCTs) on the effect of ERAS nursing on surgical site wound infection in older adults with hip fractures. Patients in the experimental group received ERAS nursing, and patients in the control group received conventional postoperative nursing. Two researchers independently completed literature screening and data extraction. The included articles were evaluated according to Cochrane quality assessment standards and the meta-analysis was conducted using Stata 17.0 software to calculate the effect sizes and their 95% confidence intervals (CIs). Twelve RCTs were included with 1117 patients, including 559 in the experimental group and 558 in the control group. In older adults with hip fractures, ERAS nursing reduced the risk of surgical site wound infection (odds ratio [OR]: 0.26, 95% CI: 0.11-0.58, p = 0.001) and postoperative complications (OR: 0.22, 95% CI: 0.14-0.33, p < 0.001), and reduced the length of hospital stay (mean difference: -4.04 days, 95% CI: -4.33 to -3.76 days, p < 0.001). In older adults with hip fractures, ERAS nursing reduces the incidence of surgical site infection and complications and shortens the length of hospital stay.

Efficacy of Pericapsular Nerve Group Block for Pain Reduction and Opioid Consumption after Total Hip Arthroplasty: A Meta-Analysis of Randomized Controlled Trials

The aim of this study was to conduct a meta-analysis of randomized controlled trials (RCTs) for comparison of the effectiveness of pericapsular nerve group (PENG) block with that of other analgesic techniques for reduction of postoperative pain and consumption of opioids after total hip arthroplasty (THA). A search of records in the PubMed, Embase, and Cochrane Library, and ClinicalTrials.gov databases was conducted in order to identify studies comparing the effect of the PENG block with that of other analgesics on reduction of postoperative pain and consumption of opioids after THA. Determination of eligibility was based on the PICOS (participants, intervention, comparator, outcomes, and study design) criteria as follows: (1) Participants: patients who underwent THA. (2) Intervention: patients who received a PENG block for management of postoperative pain. (3) Comparator: patients who received other analgesics. (4) Outcomes: numerical rating scale (NRS) score and opioid consumption during different periods. (5) Study design: clinical RCTs. Five RCTs were finally included in the current meta-analysis. Significantly lower postoperative opioid consumption at 24 hours after THA was observed in the group of patients who received the PENG block compared with the control group (standard mean difference=-0.36, 95% confidence interval -0.64 to -0.08). However, no significant reduction in NRS score at 12, 24, and 48 hours after surgery and opioid consumption at 48 hours after THA was observed. The PENG block showed better results for opioid consumption at 24 hours after THA compared with other analgesics.

Perioperative Concerns and Complaints of Patients Undergoing Total Hip Arthroplasty

Background

Preoperative concerns of patients undergoing total hip arthroplasty (THA) and their complaints during the initial postoperative period are not well investigated. We evaluated preoperative concerns of patients and patient-perceived problems during the operation and initial 5 days after the operation.

Methods

One hundred and thirty-two patients, who underwent primary THA at a tertiary referral hospital, were surveyed using a questionnaire and a face-to-face interview 1 day before the operation, operation day, and postoperative days 1, 2, 3, and 4. The severity of pain was assessed daily using a visual analog scale.

Results

The most common preoperative concern was the severity of pain after the surgery (65.2%), followed by the need of transfusion (34.8%) and postoperative rehabilitation (32.6%). Among 29 patients who could recall the experience during the operation, 12 (41.4%) suffered from shoulder pain on the contralateral side, and 6 (20.7%) answered that hammering sound had been annoying. After returning to the ward, 29 patients (22.0%) suffered from nausea, 8 (6.1%) complained of back pain, and 7 (5.3%) had ipsilateral knee pain. On postoperative day 1, 7 patients (5.3%) had persistent back pain, 8 (6.1%) had headache, and 5 (3.8%) suffered from nausea. On postoperative day 2, nine patients (6.8%) complained of radiating pain due to aggravation of pre-existing spinal stenosis, 7 (5.3%) complained of weakness of the hip flexor due to periarticular injection of ropivacaine during the operation, and 5 (3.8%) had dressing-related skin problem at the wound. On postoperative days 3 and 4, patients had no problem other than hip pain. The mean pain score was the highest (3.1 ± 1.0) on postoperative day 1.

Conclusions

The results of this study might provide information needed to solve problems and improve satisfaction of patients undergoing THA.

Paracetamol versus paracetamol/tramadol in postoperative intertrochanteric fracture: A noninferiority, randomized, controlled, double-blind study

BACKGROUND

One of the most common osteoporotic fractures among the elderly is hip fracture with tramadol frequently being prescribed for these patients. To decrease the risk of falling from tramadol, this study aimed to ascertain the effectiveness of paracetamol compared to paracetamol/tramadol for pain control following hip fixation surgery.

METHOD

This was a noninferiority, double-blind, randomized, controlled trial at a tertiary care hospital. All patients were recruited between February 2020 and March 2022. Patients were randomly assigned to paracetamol alone (Group A) or paracetamol/tramadol (Group B). All patients in both groups followed the same protocol for the first two days after surgery. To ascertain differences in pain control between the two groups, different regimens were followed from postoperative days 3-5. Pain scores were assessed by a visual analog scale (VAS). All patients were asked to complete a satisfaction questionnaire on day 5.

RESULT

A total of 30 patients were randomly allocated into Group A (paracetamol alone) and 30 into Group B (paracetamol + tramadol). The mean pain score for Group A was 5.85 ± 0.52 and 5.35 ± 0.74 for Group B. Mean cumulative doses in Group A were 4.50 ± 1.33 and 4.06 ± 1.18 in Group B. Although the mean satisfaction with pain management was higher in Group B, this was not statistically significant.

CONCLUSION

VAS scores from Group A were slightly higher than Group B. Based on a 2.0-point noninferiority margin of pain, paracetamol alone was not inferior to paracetamol/tramadol in postoperative intertrochanteric fracture.

Comparison of pericapsular nerve group (PENG) block and epidural analgesia following total hip arthroplasty: A retrospective analysis

INTRODUCTION AND OBJECTIVES

Total hip arthroplasty (THA) is an increasingly common orthopaedic procedure, with moderate to severe postoperative pain. Pericapsular nerve group (PENG) block is a recent block that seems to provide adequate analgesia without significant motor blockade. The aim of this study is to retrospectively compare the analgesic efficacy and safety of PENG block with those of epidural analgesia, in patients undergoing THA.

MATERIAL AND METHODS

This is a retrospective observational study of patients who underwent primary THA, submitted to epidural analgesia or single-shot ultrasound-guided PENG block, during a one-year period. Data regarding demographic characteristics, surgery and anaesthesia techniques, pain scores, opioid consumption, complications and time to hospital discharge were retrieved from institutional records and compared between the 2 groups (epidural analgesia vs PENG block).

RESULTS

No significant difference was found regarding pain scores, opioid consumption, and mean time to hospital discharge between the 2 groups. Pain scores at rest (1.20 epidural vs 1.67 PENG) or with movement (3.95 epidural vs 3.72 PENG) were similar between groups. Total number of complications was higher in the epidural analgesia group (50 % epidural vs 5% PENG). Paresthesia was reported in both groups. Motor block, sedation, nausea and catheter-related complications were only found in the epidural analgesia group.

CONCLUSIONS

PENG block seems to be equivalent to epidural analgesia regarding quality of postoperative analgesia for patients subject to primary THA, supporting routine use of this block in these patients. The low rate of reported complications limits conclusions on this topic.

[Analgesic effect of a new "cocktail" of local infiltration analgesia after total hip arthroplasty-A prospective randomized controlled study]

Objective

To study the analgesic effect of a new "cocktail" of local infiltration analgesia (LIA) with Deprosone after total hip arthroplasty (THA).

Methods

In a prospective randomized controlled study, 100 patients with hip joint disease requiring unilateral primary THA in West China Hospital of Sichuan University between January 2018 and December 2018 were enrolled and randomly divided into observation group and control group, with 50 cases in each group. There was no significant difference in age, gender, operative side, disease type, body mass index, American Society of Anesthesiologists (ASA) classification, preoperative rest and activity visual analogue scale (VAS) score, hip Harris score (HHS), quality of life scale (SF-12) score, and other general data between the two groups ( P>0.05). The patients in the observation group were treated with a new "cocktail" LIA around the hip joint before suturing the incision, and the drug formula was ropivacaine 200 mg, Diprospan 1 mL, morphine 10 mg, and added normal saline to 80 mL; the patients in the control group were not treated with LIA. The operation time, postoperative hospital stay, the amount of morphine used during hospitalization, and the range of motion of hip joint at discharge were recorded, and the complications were counted. The VAS score at rest and activity, HHS score, and SF-12 score [physiological score (PCS) and psychological score (MCS)] of the hip joint were recorded before and after operation, and the postoperative analgesic effect and the recovery of hip joint function were evaluated.

Results

There was no significant difference in the operation time between the two groups ( P>0.05), and the postoperative hospital stay in the observation group was significantly shorter than that in the control group ( P<0.05). The postoperative morphine consumption in the observation group was significantly less than that in the control group ( P<0.05), and the total morphine consumption in the observation group was less than that in the control group during hospitalization, but the difference was not significant ( P>0.05). Patients in both groups were followed up to 6 months after operation. The resting VAS scores of the observation group were significantly lower than those of the control group at 2, 6, 12 hours after operation and in the morning and afternoon of the first day after operation, and the active VAS scores of the observation group were significantly lower than those of the control group at 6, 12 hours after operation and in the morning of the first day after operation, and the differences were significant ( P<0.05). There was no significant difference in the resting and active VAS scores between the two groups on the day of discharge and at 3 and 6 months after operation ( P>0.05). At discharge, the flexion range of motion of hip joint in the observation group was significantly greater than that in the control group ( P<0.05), but there was no significant difference in the abduction range of motion of hip joint between the two groups ( P>0.05). There was no significant difference in HHS score and SF-12 score between the two groups at 3 and 6 months after operation ( P>0.05). There was no significant difference in analgesic satisfaction and functional satisfaction between the two groups at last follow-up ( P>0.05). There was no complication such as skin pruritus, superficial and deep infection of incision, skin necrosis, deep venous thrombosis of lower extremity, and pulmonary embolism in both groups. There was no significant difference in the incidence of complications such as nausea and vomiting, urine retention, fat liquefaction of incision, local hematoma, and large fluctuation of blood sugar between the two groups ( P>0.05).

Conclusion

The new "cocktail" LIA with Diprospan can effectively reduce the early postoperative pain of THA, reduce the dosage of opioids, shorten the length of hospital stay, and is conducive to the early functional rehabilitation of patients.

Analgesic benefits of the quadratus lumborum block in total hip arthroplasty: a systematic review and meta-analysis

The quadratus lumborum block (QLB) is reported to reduce pain and improve function following total hip arthroplasty; however, randomised controlled trials evaluating the benefits of adding this block to general or spinal anaesthesia in this population are conflicting. We performed a systematic review seeking randomised controlled trials investigating QLB benefits for total hip arthroplasty, stratifying comparisons regarding the addition of QLB to either general or spinal anaesthesia. The primary outcome was 24-h area under the curve (AUC) pain score. Pain scores were interpreted in the context of a population-specific minimal clinically important difference of 1.86 cm on a 10-cm visual analogue scale, or an AUC pain score of 5.58 cm.h. Secondary outcomes included analgesic consumption, functional recovery and opioid-related side-effects. In all, 18 trials (1318 patients) were included. Adding QLB to general or spinal anaesthesia improved 24-h AUC rest pain scores by a mean difference (95%CI) of -3.56 cm.h (-6.70 to -0.42; p = 0.034) and - 4.19 cm.h (-7.20 to -1.18; p = 0.014), respectively. These improvements failed to reach the pre-determined minimal clinically important difference, as did the reduction in analgesic consumption. Quadratus lumborum block improved functional recovery for general, but not spinal, anaesthesia. Opioid-related side-effects were reduced with QLB regardless of anaesthetic modality. Low-to-moderate quality evidence suggests that the extent to which adding QLB to either general or spinal anaesthesia reduces postoperative pain and opioid consumption after total hip arthroplasty is statistically significant but may be clinically unimportant for most patients. However, adding QLB to general anaesthesia might enhance functional recovery. Taken together, our findings do not support the routine use of QLB as part of multimodal analgesic regimens for total hip arthroplasty.

A new cocktail formula with diprospan of local infiltration analgesia in primary total hip arthroplasty: A prospective, randomized, controlled, observer-blinded study

OBJECTIVE

This study aimed to observe the analgesic effect of the cocktail formulation with diprospan during total hip arthroplasty (THA).

METHODS

From September 2018 to April 2019, 120 patients undergoing primary unilateral THA were included in this prospective, randomized, observer-blinded study. Patients were randomized into three groups, according to the different local infiltration analgesia (LIA) strategies: LIA with ropivacaine (the ropivacaine group, n = 40), LIA with a new cocktail containing ropivacaine, diprospan, and morphine (the cocktail group, n = 40), and the control group (n = 40). The primary outcomes included postoperative pain scores. The resting visual analogue scale (VAS) scores were measured at 2, 6, and 12 h after the surgery (a.m. and p.m.) on postoperative day (POD) 1, POD2, and the day of discharge. Movement VAS scores were assessed at 6 h, 12 h after the operation (a.m. and p.m.) on POD1, POD2, and the day of discharge. The secondary outcomes included opioid consumption, postoperative hospital stay, range of motion of the hip at discharge, patient satisfaction, and the results of the follow-up.

RESULTS

After the screening, 120 patients were randomized into three groups (40 patients in each group). All of the patients completed the trial. The resting VAS scores in the ropivacaine group and cocktail group at 2 h were lower than those in the control group (P < 0.001 and P < 0.001, respectively, F = 17.054), and the same trend was also postoperatively found at 6 h (p = 0.005 and P = 0.002, F = 6.212). Twelve hours after the operation, the pain score in the cocktail group was lower than that in the other two groups, but only the difference between the cocktail group and the control group was statistically significant (P = 0.018, F = 3.144). From the morning of the first postoperative day to the a.m. on POD 2, the VAS scores in the cocktail group were significantly lower than those in the ropivacaine group and the control group. Furthermore, the movement VAS scores in the ropivacaine group and the cocktail group were better than those in the control group at 6 and 12 h post-operation (P < 0.05). The per capita opioid consumption in the cocktail group was less than that in the ropivacaine group and the control group within 24 h post-operation. There were no significant differences in the comparison of additional indicators among the three groups.

CONCLUSION

The new cocktail with diprospan had a better result and longer duration time for early postoperative pain control in primary THA via the posterolateral approach under general anesthesia, especially for treating resting pain.

Peripheral Nerve Block for Hip Arthroscopy Does Not Have any Clinical Advantage Compared With Local Anesthetic Regarding Pain Management: A Meta-analysis of Randomized Controlled Trials

PURPOSE

To evaluate the efficacy of peripheral nerve block on reduction in opioid consumption and pain control after hip arthroscopy.

METHOD

To identify studies evaluating the effects of peripheral nerve block on pain control and reduction in opioid consumption in hip arthroscopy, we searched all records in the PubMed, Embase, and Cochrane Library databases until May 2021. Studies with the following characteristics were considered eligible: 1) patients who underwent a hip arthroscopy (population); 2) patients who received peripheral nerve block (intervention); 3) patients who did not receive peripheral nerve block (comparator); 4) record of total opioid consumption as a primary outcome and pain level at 1, 3 to 6, and 24 hours after surgery, patient satisfaction, and incidence of nausea and vomiting as secondary outcomes (outcomes); and 5) randomized controlled trial (study design). Data were independently extracted by two reviewers and synthesized using a random or fixed-effects model, according to the heterogeneity.

RESULTS

Eight RCTs were finally included in the meta-analysis. There were no significant differences in postoperative opioid consumption at 24 hours (standardized mean difference [SMD] = -0.091, 95% confidence interval [CI] [-0.270, 0.089]) or in visual analog scale (VAS) score at 1 (SMD = 0.299, 95% CI [-0.758, 0.160]), 3 to 6 (SMD = -0.304, 95% CI [-0.655, 0.047]), and 24 (SMD = -0.230, 95% CI [-0.520, 0.060]) hours postoperatively between the peripheral nerve block and control groups. Moreover, no significant differences were observed in patient satisfaction (SMD < 0.001, 95% CI [-0.284, 0.284]) or the incidence of nausea and vomiting (SMD = 0.808, 95% CI [0.311, 2.104]) between the two groups.

CONCLUSION

Peripheral nerve block for hip arthroscopy has no clinical advantage regarding pain management after surgery when compared with the group that received the local infiltration of analgesics without peripheral nerve block.

Does the Use of an Intra-Articular Local Anesthetic Injection During Total Hip Arthroplasty Reduce Patient Reported Pain Scores or Patient Opioid Consumption?

BACKGROUND

During primary total hip arthroplasty (THA), some surgeons use an intra-articular injection (IAI) containing 200 mg ropivacaine to target postoperative pain. There is no clear consensus on the efficacy of an IAI alone. The purpose of this study is to evaluate the effect of a 200 mg ropivacaine IAI on pain scores, opioid consumption, and mobility for primary THA patients.

METHODS

We retrospectively reviewed 571 patients who underwent primary THA at a single institution. Patients were grouped according to those who received a 200 mg ropivacaine IAI and those who did not. Primary outcome measures for this study included pain scores, morphine milligram equivalents (MMEs) dosed, distance of ambulation achieved, and time to ambulation.

RESULTS

The intervention group reported higher average pain scores with activity than the control group (P = .024). The intervention group also required higher MMEs. When striated by hour, a statistically significant uptick in pain started at 16 hours (P = .0009) and persisted to 28 hours (P = .032) in patients receiving a 200 mg ropivacaine IAI. This correlated with an increase in MMEs seen at hour 24 through 32 (P = .003 to P = .012). Level of ambulation, time to ambulation, and distance ambulated did not differ between groups. An IAI of 200 mg ropivacaine also appeared to lead to higher pain scores and higher opioid doses in males.

CONCLUSION

The IAI does not appear to reduce postoperative pain scores or MMEs dosed for THA patients. More research is needed to look at the utilization and efficacy of intra-articular ropivacaine, especially focusing on functional outcomes and gender differences.

Preemptive analgesia in hip arthroscopy: intra-articular bupivacaine does not improve pain control after preoperative peri-acetabular blockade

INTRODUCTION

Literature addressing postoperative pain management after hip arthroscopy is relatively scarce. This study aimed to assess if there was added analgesic benefit associated with postoperative intra-articular bupivacaine blockade for patients who received preoperative peri-acetabular blockade for hip arthroscopy procedures.

METHODS

52 patients were included in this comparative cohort study. Group 1 consisted of 20 patients who received preoperative peri-acetabular blockade and postoperative intra-articular blockade. The control group (Group 2), consisted of 32 patients who received only preoperative peri-acetabular blockade. Postoperative pain was recorded via visual analogue scale (VAS) pain scores, analgesic consumption, and pain diaries for 2 weeks postoperatively.

RESULTS

Postoperative VAS pain scores were significantly lower in the experimental group at the 30-minute recovery room assessment (VAS scores Group 1: 1.1; Group 2: 3.00, p = 0.034). Other than the 30-minute recovery room assessment, VAS pain scores, narcotic medication consumption, and non-narcotic analgesic consumption did not differ between the 2 groups at any time point in the study period.

CONCLUSIONS

This study did not demonstrate significant clinical benefit for patients who receive postoperative intra-articular blockade in addition to preoperative peri-acetabular blockade with bupivacaine 0.5%. We recommend the use of preoperative peri-acetabular bupivacaine blockade without intra-articular blockade postoperatively for pain control in the setting of hip arthroscopy surgery.

A systematic review and meta-analysis of efficacy of ultrasound-guided single-shot quadratus lumborum block for postoperative analgesia in adults following total hip arthroplasty

STUDY OBJECTIVE

To evaluate the efficacy of ultrasound-guided single-shot quadratus lumborum block (QLB) for postoperative analgesia in adults following total hip arthroplasty (THA).

DESIGN

Systematic review and meta-analysis.

SETTING

Perioperative period.

PATIENTS

Adult patients undergoing THA.

METHODS

Studies were identified by performing electronic searches in the following electronic databases, PubMed (Medline), Cochrane Central Registry of Trials (CENTRAL), and Google Scholar. We sought studies in adult patients undergoing THA, comparing QLB with a control group (no block, sham block or any other ultrasound guided regional nerve blocks). A total of 774 patients from 10 studies (7 randomized controlled, one controlled clinical and two retrospective study) were included in this meta-analysis.

MAIN RESULTS

The 24 hr opioid consumption was similar in both the groups [WMD -4.09; 95%CI (-9.00, 0.83); P = 0.10; I2 = 95%]. The pain scores at rest at 24 hr was significantly less in QLB group [WMD -0.62; 95% CI (-1.15, -0.10); P = 0.02; I2 = 75%].The difference in pain scores was not clinically significant. The pain scores on movement at 24 hours, time to first analgesic request and time to discharge from hospital were similar in both the groups.

CONCLUSIONS

QLB as part of multimodal analgesia did not result in any significant analgesic benefits in patients undergoing hip arthroplasty in terms of either postoperative opioid consumption or pain scores at rest and on movement. Overall, the level of certainty is low. Further, well-designed trials are required to verify the results.

Comparative analysis of analgesic effect of iliac fascial block with vertical and horizontal inguinal approach for total hip arthroplasty

OBJECTIVE

To compare and analyze the analgesic effect of iliac fascial block with vertical and horizontal inguinal approach after total hip arthroplasty.

METHODS

78 patients who admitted to our hospital and underwent unilateral total hip replacement from January 2019 to June 2020 were enrolled and randomly divided into Group A (n=40) and Group B (n=38). 30 min before surgery, the group A received ultrasound-guided iliac fascial block by vertical inguinal approach, and group B underwent ultrasound-guided iliac fascial block with horizontal inguinal approach. Both groups received patient-controlled intravenous analgesia (PCA) postoperatively. Subsequently, the postoperative VAS scores, the cumulative postoperative PCA dosage of Sufentanil, the occurrence of postoperative adverse reactions, and the overall satisfaction scores of patients with anesthesia 24 h after surgery were compared accordingly.

RESULTS

The VAS score of Group A at 4 h, 8 h, 12 h, 24 h after surgery was remarkably lower than that of Group-B (P<0.05). The cumulative Sufentanil dosage of PCA in Group A was substantially less than that in Group B (P<0.05). The incidence of adverse reactions between the two groups of patients was statistically insignificant (P>0.05). The satisfaction degree with anesthesia 24 h after surgery in Group A was notably higher than that in Group B (P<0.05).

CONCLUSION

Compared with the horizontal inguinal approach, patients received iliac fascial block by vertical inguinal approach can achieve better postoperative analgesic effect for hip replacement. It helps to reduce Sufentanil dosage and improve the patient's satisfaction with analgesia, and thus safe for clinical application.

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.

Effect of Opioids on All-cause Mortality and Opioid Addiction in Total Hip Arthroplasty: a Korea Nationwide Cohort Study

BACKGROUND

The purpose of this study was to investigate the use of opioids before and after total hip arthroplasty (THA), to find out the effect of opioid use on mortality in patients with THA, and to analyze whether preoperative opioid use is a risk factor for sustained opioid use after surgery using Korean nationwide cohort data.

METHODS

This retrospective nationwide study identified subjects from the Korean National Health Insurance Service-Sample cohort (NHIS-Sample) compiled by the Korean NHIS. The index date (time zero) was defined as 90 days after an admission to a hospital to fulfill the eligibility criteria of the THA.

RESULTS

In the comparison of death risk according to current use and the defined daily dose of tramadol and strong opioids in each patient group according to past opioid use, there were no statistically significant differences in the adjusted hazard ratio for death compared to the current non-users in all groups (P > 0.05). Past tramadol and strong opioid use in current users increased the risk of the sustained use of tramadol and strong opioids 1.45-fold (adjusted rate ratio [aRR]; 95% confidence interval [CI], 1.12-1.87; P = 0.004) and 1.65-fold (aRR; 95% CI, 1.43-1.91; P < 0.001), respectively, compared to past non-users.

CONCLUSION

In THA patients, the use of opioids within 6 months before surgery and within 3 months after surgery does not affect postoperative mortality, but a past-use history of opioid is a risk factor for sustained opioid use. Even after THA, the use of strong opioids is observed to increase compared to before surgery.

Risk factors of postoperative nausea and vomiting after total hip arthroplasty or total knee arthroplasty: a retrospective study

Background

Postoperative nausea and vomiting (PONV) is a common complication after total hip/knee arthroplasty (THA/TKA) that affects patient satisfaction and postoperative recovery. It has been reported that patients undergoing THA/TKA experience PONV at a frequency of 20–83%. This study investigates the occurrence of PONV in patients and analyzes the risk factors.

Methods

Patients undergoing primary THA/TKA under general anesthesia from October 1, 2017, to May 1, 2018, were included. Data on patient-related factors were collected before THA/TKA. Anesthesia- and surgery-related factors were recorded postoperatively. Risk factors were analyzed using binary logistic regression.

Results

A stronger association of motion sickness and PONV was found at six hours after bilateral THA/TKA [nausea: odds ratio (OR) =14.648, 3.939–54.470; vomiting: OR =8.405, 2.482–28.466]. At 6–24 hours after bilateral THA/TKA, patients who had a history of migraines tended to experience nausea (OR =12.589, 1.978–80.105). Patients with lower body mass index (BMI) were more likely to experience PONV at 24–72 hours (nausea: OR =0.767, 0.616–0.954; vomiting: OR =0.666, 0.450–0.983) after bilateral THA/TKA.

Conclusions

The incidence of PONV after primary bilateral THA/TKA was higher than that after unilateral THA/TKA. The risk factors vary at different time points after surgery, and a history of motion sickness is the most critical factor affecting PONV.

Perioperative Pain Management in Patients Undergoing Total Hip Arthroplasty: Where Do We Currently Stand?

Total Hip replacement (THR) is a well-discussed topic, and it offers excellent results in patients suffering from end-stage osteoarthritis (OA). However, despite the fact that patients can fully bear weight immediately after the surgery, THR is often associated with a great amount of postoperative pain affecting recovery and rehabilitation. Therefore, the efficient management of pain is of paramount importance. The aim of this review is to examine all the currently available strategies of pain management such as preemptive analgesia (PA), patient-controlled analgesia (PCA), and the various types of anesthesia that are used during the operation. With that objective in mind, we conducted our research by searching through the PubMed database for articles published in 2015 and after. For purely clinical reasons, we have attempted to classify all the best available evidence into three major categories: prior to surgery, during the surgery, and after the surgery. Multimodal analgesia seems to play a major role in the perioperative care of patients undergoing total hip arthroplasty (THA). Therefore, a considerable number of studies have been conducted analyzing all the current strategies that aim to minimize perioperative pain and consequent complications.

Enhanced recovery short-stay hip and knee joint replacement program improves patients outcomes while reducing hospital costs

INTRODUCTION

An attractive option to reduce hospital length of stay (LOS) after hip or knee joint replacement (THA, TKA) is to follow the Enhanced Recovery After Surgery principles (ERAS) to improve patient experience to a level where they will feel confident to leave for home earlier. The objective of this study was to evaluate the implementation of short-stay protocol following the ERAS principles.

HYPOTHESIS

We hypothesized that our ERAS THA and TKA short-stay protocol would result in a lower complication rate, shorter hospital LOS and reduced direct health care costs compared to our standard procedure.

MATERIAL AND METHODS

We compared the complications rated according to Clavien-Dindo scale, hospital LOS and costs of the episode of care between a prospective cohort of 120 ERAS short-stay THA or TKA and a matched historical control group of 150 THA or TKA.

RESULTS

Significantly lower rate of Grade 1 and 2 complications in the ERAS short-stay group compared with the standard group (mean 0.8 vs 3.0, p<0.001). No difference was found between the 2 groups for Grade 3, 4, or 5 complications. The mean hospital LOS for the ERAS short-stay group decreased by 2.8 days for the THAs (0.1 vs 2.9 days, p<0.001) and 3.9 days for the TKAs (1.0 vs 4.9 days, p<0.001). The mean estimated direct health care costs reduction with the ERAS short-stay protocol was 1489 CAD per THA and 4158 CAD per TKA.

DISCUSSION

In many short-stay protocols, focus has shifted from ERAS goals of a reduction in complications and improved recuperation to use length of stay as the main factor of success. Implementation of an ERAS short-stay protocol for patients undergoing THA or TKA at our institution resulted not only in reduced hospital LOS, but also in improved patient care and reduced direct health care costs.

LEVEL OF EVIDENCE

Pain monitoring and management in a rehabilitation setting after total joint replacement

Total hip replacement (THR) and, particularly, total knee replacement (TKR), are painful surgical procedures. Effective postoperative pain management leads to a better and earlier functional recovery and prevents chronic pain. Studies on the control of pain during the postoperative rehabilitation period are not common. The aim of this study is to present results of a perioperative anesthetic protocol, and a pain treatment protocol in use in the Orthopaedic and the Rehabilitation intensive units of our Hospital. 100 patients (50 THR and 50 TKR) were retrospectively included in this observational study. Numeric Rating Scale (NRS) for pain at rest registered in the clinical sheet was retrieved for all patients and analyzed with respect to the spinal anaesthesia given for the surgery, local analgesia, analgesia protocol adopted during the postoperative days in the Orthopaedic Unit, the antalgic treatment given during the stay within the Rehabilitation Unit, the postoperative consumption of rescue pain medication, and any collateral effect due to the analgesic therapy. Patients reached standard functional abilities (walking at least 50 meters and climbing/descending stairs) at a mean length of 8 days without medication-related complications. Mean NRS during the time of stay was 1.3 ± 0.3 for THR and 1.3 ± 0.2 for TKR) and maximum mean NRS was 1.8 ± 0.5 for TKR and 1.8 ± 0.6 for THR. The use of rescue therapy in the rehabilitation guard was correlated with the mean NRS pain and the maximum NRS pain. A very good control of pain with the perioperative anesthetic protocol and pain treatment protocol in use was obtained.

The Influence of Presurgical Factors on the Rehabilitation Outcome of Patients Following Hip Arthroplasty

PURPOSE

The aims of this study were to evaluate the relationship between sociodemographic information, anthropometric values, clinical and presurgery factors, and length of stay (LOS) in older adult patients undergoing total hip arthroplasty (THA) and to predict which factors can delay the start of the rehabilitation program and increase the corresponding LOS.

METHODS

A prospective cohort study was conducted in an orthopedic inpatient unit with 40 patients undergoing THA.

FINDINGS

The Morse Fall Scale scores and pain intensity scores delayed the commencement of the rehabilitation program. Gender and social support were important determinants of LOS and rehabilitation outcome following THA. The weight of the lower limb without osteoarthritis followed by pain intensity and overweight patients also influenced LOS.

CONCLUSIONS/CLINICAL RELEVANCE

Functional outcomes after THA are variable, and the rehabilitation process is an important factor to regain their normal level of physical functioning. This factor can have an impact in the discharge of patients, in resource allocation and in health care of older adult patients.

Preoperative intravenous glucocorticoids can decrease acute pain and postoperative nausea and vomiting after total hip arthroplasty: A PRISMA-compliant meta-analysis

BACKGROUND

A systematic review and meta-analysis of published randomized controlled trials (RCTs) were performed to assess the efficacy and safety of preoperative intravenous glucocorticoids versus controls for the prevention of postoperative acute pain and postoperative nausea and vomiting (PONV) after primary total hip arthroplasty (THA).

METHODS

A computer literature search of electronic databases, including PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, China National Knowledge Infrastructure (CNKI), and China Wanfang database, was conducted to identify the relevant RCTs comparing preoperative intravenous glucocorticoids versus placebos for reducing acute pain and PONV in THA patients. The primary outcomes included the use of the visual analog scale (VAS) with rest or mobilization at 6, 24, 48, and 72 hours and the occurrence of PONV. The secondary outcome was total morphine consumption. We calculated the risk ratio (RR) with a 95% confidence interval (95% CI) for dichotomous outcomes, and the weighted mean difference (WMD) with a 95% CI for continuous outcomes.

RESULTS

Pooled data from 7 RCTs (411 THAs) favored preoperative intravenous glucocorticoids against acute pain intensity at 4, 24, and 48 hours (P < .05). There was no significant difference between the VAS with rest or mobilization at 72 hours (P > .05). Subsequently, preoperative intravenous glucocorticoids provided a total morphine-sparing effect of 9.36 mg (WMD = -9.36, 95% CI = -12.33 to -6.38, P = .000). In addition, preoperative intravenous glucocorticoids were associated with a significant reduction of the occurrence of PONV (RR = 0.41, 95% CI = 0.30-0.57, P = .000).

CONCLUSION

Intravenous glucocorticoids can decrease early pain intensity and PONV after THA. However, the low number of studies and variation in dosing regimens limits the evidence for its use. Thus, more high-quality RCTs are still needed to identify the optimal drug and the safety of intravenous glucocorticoids.

Perioperative Pain Management in Hip and Knee Arthroplasty

Total hip and knee arthroplasty is associated with significant perioperative pain, which can adversely affect recovery by increasing risk of complications, length of stay, and cost. Historically, opioids were the mainstay of perioperative pain control. However, opioids are associated with significant downsides. Preemptive use of a multimodal pain management approach has become the standard of care to manage pain after hip and knee arthroplasty. Multimodal pain management uses oral medicines, peripheral nerve blocks, intra-articular injections, and other tools to reduce the need for opioids. Use of a multimodal approach promises to decrease complications, improve outcomes, and increase patient satisfaction after hip and knee arthroplasty.
