Lexion AP 50/30 Warmed Humidified Real Time CO2 Insufflation vs Airseal Recirculated CO2/Air Insufflation in Minimally Invasive Bariatric (Gastric Bypass) Surgery: A Randomized Controlled Study of Clinical Evaluation

Overview

The purpose of this study is to To determine the effect of warm and humidified (WH) carbon dioxide (CO2) on post-operative pain/analgesia requirement in patients undergoing laparoscopic bariatric surgery.

Interventions

  • Device Warm humidified CO2
    Participants will receive warm (37°C) and humidified (95%) CO2.The humidification and warming device to be used is AlwaysPneumo® AP 50/30 InsuflowPort® (Lexion Medical, FDA approved) which is a specialized port that delivers warmed (95° F) and humidified (95% relative humidity) CO2, the source of which is a standard CO2 tank or wall source
  • Device Dry CO2
    Participants will receive standard cold (19-21 °C) and non-humidified (0%) CO2 insufflation with Airseal Insufflator

Primary outcome measures

  • Pain as assessed by the visual analog scale (VAS) [Time frame: First 24 hours after surgery]
Secondary outcome measures (10)
  • Intraoperative temperature measured via bladder probe (average of the measurements on the anesthesia record) [Time frame: From the start surgery to the end of the surgery in minutes]
  • Temperature in the PACU [Time frame: From the time the patient enters PACU to the time patient leaves the PACU in minutes]
  • Analgesic requirements in the Post Anesthesia Care Unit (PACU) [Time frame: From the time the patient enters the PACU to the time patient leaves the PACU in minutes]
  • Volume of CO2 consumed during the procedure [Time frame: from the time the CO2 machine is turned on to the time the CO2 machine is turned off in minutes]
  • Length of hospital stay [Time frame: the amount of hours the patient stays in the hospital (ie 24 hours)]
  • Duration of surgery [Time frame: From start of the surgery to the end of the surgery in minutes]
  • Incision length [Time frame: measurement in centimeters the patients incision lengths at the closing of the surgery]
  • Intra-operative and total hospital costs [Time frame: from the admission to discharge of the patient in hours]
  • Total narcotic use intra-operatively (in morphine milliequivalents) [Time frame: volume of narcotics used from the beginning of surgery to end of surgery in milliequivalents]
  • Postoperative Analgesia Requirement measured in morphine milliequivalents [Time frame: any postoperative analgesia used after the surgery is completed to the discharge of the patient from the hospital]
