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

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.

Primary outcomes

  1. VAS-score 4 hours postoperative during movement

    Time frame: 4 hours postoperative

    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.

Secondary outcomes

  1. VAS-score 0-24 hours postoperative during movement

    Time frame: 0-24 hours postoperatively

    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.

  2. VAS-score 0-24 hours postoperative at rest

    Time frame: 0-24 hours postoperatively

    VAS-score 0, 1, 2, 4, 8, 12, and 24 hours postoperative at rest. VAS-score: 0-100 mm; 0: no pain, 100: worst imaginable pain.

  3. Oxynorm consumption

    Time frame: 0-24 hours postoperative

    Oxynorm consumption 24 hours postoperative

  4. time to first oxynorm requirement

    Time frame: 0-24 hours postoperatively

  5. Mobilization

    Time frame: 0-24 hours postoperatively

    time to first mobilization

  6. Mobilization

    Time frame: 0-24 hours postoperatively

    Ability to mobilize judged by the cumulated ambulation (CAS) score: 0-6; 0 no mobilization, 6: fully mobilized

  7. Length of stay

    Time frame: 0-7 days postoperative
