Postoperative Pain

Brief summary

The purpose of this study is to compare between two surgical techniques for anterior abdominal wall blocks in obese patients Undergoing Major Gynecological Surgery: Surgical Transversus Abdominis Plane \[TAP\] block versus Rectus Sheath block as regards the efficacy and adverse effects

Interventions

PROCEDURESurgical Transversus Abdominis Plane Block

At the end of operation and after hemostasis, 20 ml of 0.25% bupivacaine will be injected intra-abdominally into the Transversus Abdominis plane at the midpoint of the line connecting the crista iliaca and inferior costal margin and at two locations in the lateral abdominal wall at 3-4 cm inferior to the previous midline injection. The same procedure will be repeated on the opposite side using an identical amount of local anesthetic.

At the end of operation and after hemostasis,20 ml 0.25% bupivacaine will be administered slowly under direct vision after careful aspiration to the rectus sheath space which is present inbetween rectus abdominis muscle and the posterior layer of its sheath at the upper pole of the midline incision by time of closure of the anterior abdominal wall. The procedure will be repeated on the opposite side.

Design outcomes

Primary

MeasureTime frame
Total dose of morphine consumptionFirst 24 hours postoperatively

Secondary

MeasureTime frameDescription
Numerical rate scaleFirst 24 hours postoperativelyPostoperative pain will be assessed at rest and coughing using numerical rate scale (NRS) patients are asked to rate their pain on a scale from 0 to 10, where 0 represents no pain and 10 represents the worst pain possible,.
Postoperative respiratory functionsFirst 24 hours postoperativelywill be measured using incentive spirometer. Patients were asked to do sustained maximal inspiration (SMI) three times. Then average SMI will be recorded. They will be instructed prior to induction of general anesthesia about the usage of incentive spirometer then a basal measurement will be obtained. After recovery, measurement will be obtained on 60 min, 6 hours, 12 hrs and 24 hrs.
