Comparison between supra-inguinal fascia iliaca and pericapsular nerve group blocks on postoperative pain and functional recovery after total hip arthroplasty: A noninferiority randomised clinical trial

Effects of pericapsular nerve group block versus local anesthetic infiltration for postoperative analgesia in total hip arthroplasty: A protocol for systematic review and meta-analysis

INTRODUCTION

This protocol for a systematic review and meta-analysis aims to provide synthesized evidence to determine whether pericapsular nerve group (PENG) block is superior to local anesthetic infiltration in controlling postoperative pain in total hip arthroplasty.

METHODS AND ANALYSIS

PubMed, EMBASE, Web of science, and the Cochrane library will be systematically searched from their inception to December 30, 2024. Randomized controlled trials (RCTs) that compared the analgesic effects of PENG block with local anesthetic infiltration for total hip arthroplasty will be included. The time to first analgesics requirement (analgesia duration) will be the primary outcome. Secondary outcomes will include the postoperative analgesics consumption over 24 hours, visual analog scale (VAS) scores at rest and movement, and the incidence of adverse effects. Statistical analysis will be conducted by RevMan 5.4 software.

Continuous Suprainguinal Fascia Iliaca Block for Postoperative Analgesia Management After Hip and Knee Arthroplasty Surgeries: A Report of Two Cases

Knee and hip arthroplasty are common orthopedic procedures that are frequently associated with moderate to severe postoperative pain. Regional anesthesia techniques play a crucial role in multimodal analgesia strategies for managing postoperative pain. The suprainguinal fascia iliaca (SIFI) block is an effective regional anesthesia technique frequently used for postoperative analgesia in lower extremity surgeries, including knee and hip arthroplasty. These techniques can be safely applied either as a single-shot injection or via continuous catheter insertion. In this case report, we describe our experience with the use of continuous SIFI block for postoperative analgesia in knee and hip arthroplasty.

Is pericapsular nerve group block superior to other regional analgesia techniques following total hip arthroplasty? a systematic review and network meta-analysis

BACKGROUND

A systematic review and network meta-analysis (NMA) to compare the safety and efficacy of pericapsular nerve group block (PENGB) with other regional analgesia techniques in patients undergoing total hip arthroplasty (THA).

METHODS

We searched PubMed, Embase, Web of Science, and the Cochrane Library for relevant research from inception to May, 2024. Randomized controlled trials (RCTs) comparing PENGB with other regional analgesia techniques in patients undergoing THA were included. The primary outcome was resting pain scores at 6 h after surgery. The NMA was made by using Stata 15.1 software. Potential risk of bias was assessed by using CINeMA. Sensitivity and subgroup analyses were performed on the primary outcome.

RESULTS

A total of 11 RCTs including 766 patients were eligible for inclusion. For postoperative resting and movement pain scores within 24 h analysis, PENGB + periarticular local anesthetic infiltration (PLAI) was found to be significantly more effective than other treatments and its Surface under the cumulative ranking curve (SUCRA) was the lowest. Moreover, PENGB + PLAI was ranked the best in reducing opioid consumption within 24 h and the length of hospital stay. PENGB was found to have significantly lower incidence of quadriceps motor block and postoperative nausea and vomiting (PONV).

CONCLUSIONS

PENGB is more likely to reduce the incidence of quadriceps motor block and PONV in patients undergoing THA, but PENGB + PLAI is superior to other regional analgesia techniques (PLAI, PENGB, fascia iliaca compartment block, and quadratus lumborum block) in improving postoperative pain and shortening the length of hospital stay.

Ultrasound-Guided Suprainguinal Fascia Iliaca Compartment Block in Patients Undergoing Hip Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

The use of fascia iliaca compartment block (FICB) has been widely encouraged for hip surgery; however, meta-analyses showed mixed results in terms of its efficacy in reduction in analgesic consumption and pain score. These meta-analyses included all forms of FICB approaches, which may diminish the effect size of the therapy. Suprainguinal FICB (s-FICB) has been shown to be superior to other FICB approaches including the ultrasound-guided infrainguinal approach and the landmark approach. This systematic review and meta-analysis aim to compare opioid consumption, pain score, and complications after s-FICB to control for patients undergoing hip surgery. The study protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) (registration number CRD42023460377). We performed a systematic literature search in Medical Literature Analysis and Retrieval System Online (MEDLINE), Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) electronic databases from inception to 16 August 2023 to identify randomized controlled trials (RCTs) that evaluated the efficacy of s-FICB versus control for patients undergoing hip surgery. Data were independently extracted by two reviewers, and disagreements were resolved by consensus or by discussion with a third investigator. The primary outcome is the 24-hour oral morphine equivalent daily dose (oMMED). The secondary outcome includes oMMED at different timepoints, and pain score. The Cochrane risk of bias tool (Cochrane, London, England) was used to assess the risk of bias. The certainty of evidence was assessed via the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Data were synthesized using a random-effects model. Trial sequence analysis is performed on opioid consumption 24 hours post operation. Eleven randomized controlled trials were included. Arthroscopic hip surgery was performed in three studies involving 222 patients, hip and femur fracture surgeries were performed in three studies involving 149 patients, and total hip arthroplasty was performed in five studies involving 483 patients. In studies involving arthroscopic hip surgery, s-FICB did not improve intra-operative and post-operative opioid consumption and post-operative pain score. In studies involving hip and femur fracture surgeries, s-FICB was associated with a non-significant difference in opioid consumption at 24 hours after surgery and post-operative pain score at 12 hours and 24 hours after surgery. However, the result of the trial sequential analysis (TSA) was not definitive, indicating that additional research is necessary to draw conclusive outcomes. In studies involving total hip arthroplasty, s-FICB was associated with a significant reduction in post-operative opioid consumption at 24 and 48 hours with conclusive results in trial sequential analysis. In conclusion, s-FICB is superior to placebo for patients undergoing total hip arthroplasty. For patients undergoing arthroscopic hip surgery, s-FICB is unlikely to be beneficial. With regard to hip fracture surgery, additional research is necessary to draw conclusive outcomes.

Ultrasound-Guided Suprainguinal Fascia Iliaca Block as Part of Anesthesia Management for Lower Extremity Surgeries: A Single-Center Retrospective Cohort Feasibility Study

Study objective The ultrasound-guided (US-guided) suprainguinal fascia iliaca block (SIFIB) is a regional anesthesia procedure that targets the lumbar plexus. It offers versatility in clinical practice, serving as both a standalone method for adequate pain management and a primary anesthesia option. Our aim was to present clinical insights gained from the application of US-guided SIFIB, whether as a standalone procedure or in conjunction with another block, across various clinical indications for lower extremity surgeries. Methodology Our study is a retrospective cohort analysis designed to identify cases in which the SIFIB was used as a component of the main anesthetic method and to determine the success of the anesthetic method in patients undergoing lower extremity surgery between March 2022 and March 2023 in a tertiary hospital. Data such as block success, perioperative additional analgesic need, patients' demographic details, and block characteristics were obtained from electronic and paper-based patient records and analyzed. Main results  We analyzed data from 16 patients who underwent lower extremity surgeries under SIFIB. Among these, 10 patients received SIFIB as their sole anesthesia method, while six underwent surgery with a combination of sciatic block and SIFIB. Briefly, the types of surgery were amputations, soft tissue excision, revision of knee prostheses, excision of knee tumors, patella implant removal, patellar ligament repair, patellar fracture repair, distal femur fractures (internal fixation), and vascular surgery. Six patients necessitated additional analgesics. No statistically significant differences were observed in demographic details, block onset time, and surgical duration between patients requiring and not requiring sedoanalgesia during surgery (p>0.05). Conclusion For patients planning lower extremity surgery, considering SIFIB alone or combined with a sciatic block as part of anesthesia management is a valid option, offering an alternative to a lumbar plexus block.

Effect of ultrasound-guided pericapsular nerve group (PENG) block on pain during patient positioning for central nervous blockade in hip surgery: a randomized controlled trial

BACKGROUND

Most patients with hip fractures are elderly patients with comorbidities, and well-managed pain management is associated with positive postoperative outcomes. In recent years, new indications for regional anesthesia techniques have been defined, and they have found more place in clinical practice. Herein we investigate the effect of US-guided PENG block on positioning pain and compare that effect to intravenous opioid in patients undergoing surgery under spinal anesthesia for hip fractures. Additionally, we sought to investigate the effect of PENG block on pain scores, opioid intake, time to first analgesic requirement, and quality of recovery within the first 24 h following surgery.

METHODS

In this study, patients were divided into the PENG (n = 42) and control group (n = 42) one hour prior to surgery. A team who was blinded to the assigned groups, collected and evaluated all data such as spinal anesthesia positioning pain, postoperative pain, opioid requirement.

RESULTS

Patients that underwent PENG had statistically significantly lower NRS scores after interventions, immediately before positioning, at positioning and at end of spinal anesthesia. Pain scores during positioning for spinal anesthesia were statistically significantly lower in the PENG group than in the control group (p < 0.001). Total morphine use over the first 24 h was extremely statistically significantly lower in the PENG group (p < 0.001).

CONCLUSIONS

Positive outcomes of PENG block in patient positioning pain before spinal anesthesia, postoperative pain scores, and morphine consumption are consistent with similar studies. High patient satisfaction in patients who underwent PENG block contributes to the literature.
