Background and Aims The pericapsular nerve group (PENG) block has emerged as an innovative technique for providing analgesia and post operative preservation of motor function in hip fracture surgeries. However, comparative evaluation of the efficacy of PENG block with the conventional regional techniques, e.g. femoral nerve block, fascia iliaca compartment block, etc. is yet to be established.

Methods A comprehensive screening of electronic databases is performed up to 15th February 2022.Only randomized controlled trials evaluating the impact of PENG block during hip surgeries in terms of analgesia, and preservation of motor function are included in this meta-analysis.

Results We retrieved in eight RCTs, with a total of 394 patients, over all the application of PENG block during hip surgeries led to lesser requirement of rescue analgesia [Odds ratio (OR) 0.49, 95% CI 0.24 to 0.98, I² =0%], and lesser risk of post-procedural muscle weakness [OR 0.08, 95% CI 0.03 to 0.20, I² =0%] in the initial 24 hrs after surgery. However, In sub-group analysis, patients with fascia iliaca compartment block shows similar requirement of rescue analgesia. [OR 0.66, 95% CI 0.20 to 2.16, I² =0%]

Conclusions PENG block is a novel alternative for presently available regional techniques for hip surgery, it provides better analgesia with preserves of muscle power. However, larger RCTs are the need of the hour to further substantiate the findings.
