Femoral nerve block for analgesia in patients having knee arthroplasty.

摘要

IN this issue of Anesthesiology, Paul et al. report results of their meta-analysis on femoral nerve block (FNB) analgesia and outcome after total knee arthroplasty. The authors conclude that FNB (plus patient-controlled analgesia) is a good alternative to patient-controlled analgesia alone or epidural for postoperative analgesia in patients having total knee arthroplasty and that the current evidence does not support using either a sciatic nerve block or continuous FNB (CFNB) in addition to a single-injection FNB in this patient population.
