Review Meta Analysis
Psoas compartment block for lower extremity surgery: a meta-analysis.
Psoas compartment block (PCB) is a potentially useful but controversial technique for lower limb surgery. We have conducted a systematic review of the efficacy and safety of PCB for anaesthesia and postoperative analgesia for hip and knee surgery. Relevant studies were identified within PubMed, EMBASE, and the Cochrane Library. ⋯ Although PCB combined with sciatic nerve block and sedation is an effective technique for minor knee surgery, there is currently insufficient data to recommend the use of this approach for hip and major knee surgery. PCB is a safe and effective alternative for analgesia after hip and knee surgery. More research is required to define its role in the intraoperative setting and confirm potentially beneficial effects on variables such as perioperative haemodynamics and blood loss.
