Retrospective Femoral Nerve Block Study

This study has been completed.
Information provided by (Responsible Party):
Joseph D. Tobias, Nationwide Children's Hospital Identifier:
First received: February 9, 2011

Last verified: January 2012
This is a retrospective review to evaluate the efficacy of femoral nerve block in providing analgesia following reconstructive surgery of the knee and to compare the postoperative course of patients who received femoral nerve block with a retrospective cohort who were cared for prior to the institution of a regional anesthesia program. The investigators hypothesize that femoral nerve blockade limits postoperative opioid needs, improves analgesia and facilitates discharge home when compared to intravenous opioid use following reconstructive knee surgery.
