A retrospective review of femoral nerve block for postoperative analgesia after knee surgery in the pediatric population.

Background: To investigate the outcomes of pediatric patients receiving a femoral nerve block (FNB) in addition to general anesthesia for arthroscopic knee surgery compared with those receiving general anesthesia alone.

Methods: This retrospective review included all patients undergoing arthroscopic knee surgery from January 2009 to January 2011 under general anesthesia both with and without a FNB. After the induction of general anesthesia, those patients selected for regional anesthesia received a FNB using real-time ultrasound or nerve stimulator guidance.
