Quadratus Lumborum Block Versus Fascia Iliaca Block for Hip Arthroplasty

NCT04005326 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 34

Last updated 2019-07-08

No results posted yet for this study

Summary

Quadratus lumborum block is a newly developed block with good performance in lower abdominal surgery. In a cadaveric study, the spread of local anesthetic in the anterior approach of QL block (QL3) was reported to cover nerve roots from T10 to L3. Thus, it was hypothesized that this approach could be used in hip surgeries with minimal motor affection.

This study aims to compare QL3 block and suprainguinal Fascia Iliaca block in the duration of postoperative analgesia, pain scores, motor power in quadriceps muscle, and side effects.

Conditions

  • Post Operative Pain

Interventions

PROCEDURE

quadratus lumborum block; (Anterior QLB or QLB III)

The patient will be in the lateral position. A low frequency convex probe will be vertically attached above the iliac crest and a needle will be inserted in plane from the posterior edge of the convex probe through the quadratus lumborum in an anteromedial direction. The needle tip will be placed between the psoas major muscle and the quadratus lumborum muscle. After negative aspiration, 30 mL of 0.25 % of bupivacaine will be injected into the fascial plane incrementally, aspirating every 5 ml.

PROCEDURE

suprainguinal fascia iliaca block

In supine position, a high frequency linear probe will be placed in the inguinal crease. Scan starting laterally from the femoral artery and nerve in inguinal crease to identify the sartorius muscle, tracing the muscle until it's origin to anterior superior iliac spine. The shadow of the bony of iliac crest \& iliacus muscle will be seen, the end point of the injection is deep to the fascia iliaca and above the iliacus muscle in the lateral part of the iliacus muscle. After negative aspiration, 30 mL of 0.25 % of bupivacaine will be injected under the fascial plane incrementally, aspirating every 5 ml.

PROCEDURE

Subarachnoid block

Patients will receive SAB using 25g spinal needle in the lateral position. Fifteen milligrams of hyperbaric bupivacaine will be administered at L3-L4 or at L4-L5 interspace in addition to 25 mcg fentanyl with rapid crystalloid co-load. Spinal anesthesia will be considered successful when a bilateral block to T12, as assessed by loss of cold (cold ice) and pain (a 23-gauge needle) sensations, will be established 10 -minutes after the intrathecal injection. If spinal anesthesia failed, such patients will be administered general anesthesia and will be excluded from this study.
