Summary

Laparoscopic gastric-bypass surgery (LGBS) is one of the surgical treatments for morbid obesity, which is performed under general anesthesia. TAP block is an analgesic strategy covering the dermatomes from T6 to L1 and consists of injecting local anesthetic in the TAP between the costal margin and the iliac crest, where the thoracolumbar nerves (T6-L1) are located. As far as the investigators know, this analgesic technique has never been studied in LGBS. The investigators objective is to determine whether an ultrasound (US)-guided TAP block provides improved analgesia during the first 24 hours after laparoscopic gastric-bypass surgery, compared to conventional therapy only.

Conditions

• Gastric-bypass Surgery
• Opioid Consumption
• Obesity

Interventions

Type	Name	Description
PROCEDURE	TAP-Block	Block needle will be inserted out-of-plane to the ultrasound beam, perpendicular to the skin surface, until the tip lies deep between the fascia of the transversus abdominis muscle and the internal oblique muscle. 30 ml of the study solution in each side will be injected at this location and should be observed to spread in an anterior-posterior direction between two muscles. Each patient will receive a total dose of 60 ml of 0.25% bupivacaine (150 mg) + 1:200,000 epinephrine.
OTHER	Conventional Managment	For these group.no TAP block administration. just conventional management for post operative pain.
