REduced Pain After Bariatric Surgery - Gastric Bypass

This study aims to analyze the effect of laparoscopic guided transversus abdominis plane (LG-TAP) block compared to placebo for postoperative analgesia following laparoscopic gastric bypass. One group of participants received a (LG-TAP) block with local anesthetic while the other group received (LG-TAP) block with saline solution (placebo).

Treatment and study plan

LG-TAP block with local anesthetic

Drug

The laparoscopic guided TAP Block was performed by surgeon at the beginning of surgery, injecting 15 ml of Ropivacaine 0.5% on each side, using an atraumatic needle (10/15 cm length, 20 Gauge diameter) close to the anterior axillary line, between the iliac crest and the subcostal margin. Correct needle tip positioning between the transverse muscle of the abdomen and the internal oblique was verified through laparoscopic guidance.

Port site infiltration

Procedure

Prior the surgical incision, an infiltration of the laparoscopic access using a total of 10 ml Ropivacaine 0.5% was performed by surgeon

LG-TAP block with saline solution

Drug

The laparoscopic guided TAP Block was performed by surgeon at the beginning of surgery, injecting 15 ml of Saline solution (NaCl 0.9%) on each side, using an atraumatic needle (10/15 cm length, 20 Gauge diameter) close to the anterior axillary line, between the iliac crest and the subcostal margin. Correct needle tip positioning between the transverse muscle of the abdomen and the internal oblique was verified through laparoscopic guidance.

Primary outcomes

    Time frame: 24 hours

    A numerical rating scale (NRS) from 0 (no pain) to 10 (worst imaginable pain) will be used to evaluate pain at rest during 24 hours after surgery

Secondary outcomes

  1. Morphine Consumption

    Time frame: 24 hours

    Total of intravenous morphine (expressed in milligrams) administered administered during the first 24 hours after surgery

  2. Ketorolac Consumption

    Time frame: 24 hours

    Total of intravenous toradol (expressed in milligrams) administered administered during the first 24 hours after surgery

  3. Nausea and/or Vomiting

    Time frame: 48 hours

    Incidence of nausea and/or vomiting

  4. Length of Hospital Stay

    Time frame: 72 hours

    Time between surgery and dismission from the hospital

  5. Timt to walking

    Time frame: 72 hours

    Time between surgery and patient starting to walk

  6. Time to first flatus

    Time frame: 72 hours

    Time between surgery and patient having flatus

  7. Surgical Complications

    Time frame: 7 days

    Incidence of complications related to surgery
