Can Intraoperative systemic lidocaine decrease postoperative opioid consumption and improve quality of recovery after laparoscopic gastric bypass surgery? The hypotheses:does the use of intraoperative systemic lidocaine decrease postoperative opioid consumption and improve quality of recovery after laparoscopic gastric bypass surgery.

This study has the potential to confirm an opioid sparing strategy for morbid obese patients undergoing laparoscopic gastric bypass surgery. The high incidence of obstructive sleep apnea and the increased risk of postoperative hypoxemia make the development of opioid sparing techniques in this patient population warranted.

Primary Outcome Measures:
  • Quality of Recovery 40 on the Day After Surgery [ Time Frame: 24 hours ]

    Quality of Recovery 40 on the Day After Surgery. The survey is a quality of recovery tool and a score of 40 is low and 200 is high.

    The minimum score is 40 which is minimum recovery score and them maximum score is 200 which is considered better recovery.

Secondary Outcome Measures:
  • 24 Hour Total Opioid Consumption [ Time Frame: 24 hours post surgery ]
    24 hour total opioid consumption using IV morphine equivalents

Enrollment: 51
Study Start Date: June 2010
Study Completion Date: November 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
