Effect of a Lateral Nerve of the Thigh Block on Postoperative Pain After Total Hip Replacement Surgery

Daniel Hägi-Pedersen100 enrolled

Overview

The purpose of this study was to evaluate the analgesic efficacy of the nervus cutaneous femoral lateralis (NCFL) blockade on postoperative pain after total hip replacement surgery. The NCFL-block is a pure sensory block. We hypothesized that the NCFL-block would reduced the postoperative pain without delaying mobilization.

Outcomes

Primary Outcomes

VAS-score 4 hours postoperative during movement

VAS-score 4 hours postoperative during 30 degrees of flexion of the hip. VAS-score: 0-100 mm; 0: no pain, 100: worst imaginable pain.

Time frame: 4 hours postoperative

Secondary Outcomes

VAS-score 0-24 hours postoperative during movement

VAS-score 0, 1, 2, 8, 12, and 24 hours postoperative during 30 degrees of flexion of the hip. VAS-score: 0-100 mm; 0: no pain, 100: worst imaginable pain.
