NCT05533424

Brief Summary

Abdominal surgery is usually associated with severe postoperative pain. The transverse abdominal plane (TAP) block is considered an effective means for pain control in such cases. The quadratus lumborum (QL) block is another option for the management of postoperative pain. The aim of this study is to evaluate the efficacy and safety of quadrates lumborum blocks and Transversus abdominis plane blocks for pain management after abdominal cancer surgery.

Study Arms (2)

Group quadratus lumborum

ACTIVE COMPARATOR

the patient will be positioned supine with lateral tilt , and the transducer was placed at the level of the anterior superior iliac spine and moved cranially until the three abdominal wall muscles were clearly identified. The external oblique muscle was followed posterolaterally until its posterior border was visualized . The probe was tilted down to identify a bright hyperechoic line that represented the middle layer of the thoracolumbar fascia. The needle will be inserted in plane from anterolateral to posteromedial. The needle tip was placed between the thoracolumbar fascia and the QL muscle, and after negative aspiration, the correct position of the needle was proved by injection of 5 mL of normal saline to confirm the space with a hypoechoic image and hydrodissection. An injection of 20 mL of 0.25% bupivacaine was applied

Other: quadratus lumborum

Group transversus abdominis plane

ACTIVE COMPARATOR

the probe will located between the iliac crest and the lower costal margin in the anterior axillary line at the level of umbilicus, and the layers of abdominal wall were identified (external oblique, internal oblique, and transverse abdominis muscles). In-plane technique was used and the tip of the needle was inserted between the internal oblique and transverse abdominis muscles. After negative aspiration (to exclude intravascular injection), 20 mL of 0.25% bupivacaine was injected. The same technique will be performed on the other side

Other: transversus abdominis plane
