Summary

This is a randomized noninferiority interventional study to determine the equivalence of two adductor canal block (ACB) methods: mid-thigh and distal thigh in patients undergoing medial foot, medial ankle, or medial leg surgery. Sixty eight patients will be identified during their orthopedic presurgical clinic visit, anesthesia preoperative clinic visit or Day Surgery Unit (Zale Lipshy Hospital, Clements University Hospital, and University of Texas Southwestern Outpatient Surgery Center) for eligibility. Eligible individuals may be introduced to the study in the orthopedic presurgical clinic or the anesthesia preoperative clinic by staff. After consent patients will be randomized (break-seal method) to receive either a mid-thigh or distal thigh block using ropivacaine prior to foot, ankle, or leg surgery. The following measurements will be obtained to determine the change in sensory distribution: pinprick test with Neuropen, maximum voluntary isometric contraction before and after block, postoperative pain scores (24 hrs and at discharge) and postoperative opiate consumption.

Conditions

  • Postoperative Pain

Interventions

DRUG

Ropivacaine

Ropivacaine is routinely used to perform localized blockade prior to surgery to improve management of postoperative pain.
