Pericapsular Nerve Group (PENG) block versus fascia iliaca compartment (FI) block for hip surgery: a systematic review and meta-analysis of randomized controlled trials.
Brazilian Journal of Anesthesiology 2023 July 27
BACKGROUND: This study compares Fascia Iliaca compartment (FI) block and Pericapsular Nerve Group (PENG) block for hip surgery.
METHODS: Pubmed, Embase and Cochrane were systematically searched in April 2022. Inclusion criteria were: Randomized Controlled Trials (RCTs); comparing PENG block versus FI block for hip surgery; patients over 18 years of age; and reporting outcomes immediately postoperative. We excluded studies with overlapped populations and without a head-to-head comparison of the PENG block vs. FI block. Mean-Difference (MD) with 95% Confidence Intervals (CI) were pooled. Trial Sequential Analyses (TSA) were performed to assess inconsistency. Quality assessment and risk of bias were performed according to Cochrane recommendations.
RESULTS: Eight RCTs comprising 384 patients were included, of whom 196 (51%) underwent PENG block. After hip surgery, PENG block reduced static pain score at 12h post-surgery (MD = 0.61 mm; 95% CI 1.12 to -0.09; p = 0.02) and cumulative postoperative oral morphine consumption in the first 24h (MD = -6.93 mg; 95% CI -13.60 to -0.25; p = 0.04) compared with the FI group. However, no differences were found between the two techniques regarding dynamic and static pain scores at 6h or 24h post-surgery, or in the time to the first analgesic rescue after surgery.
CONCLUSION: The findings suggest that PENG block reduced opioid consumption in the first 24 h after surgery and reduced pain scores at rest at 12h post-surgery. Further research is needed to fully understand the effects of the PENG block and its potential benefits compared to FI block.
