Intravenous Acetaminophen Use With Bariatric Surgery on Morbidly Obese Patients
Bariatric patients usually require the use of either intravenous or oral opioid medications. The use of opioids, however, is often associated with side-effects such as nausea, sedation pruritus, urinary retention and respiratory depression with often delay patient discharge. This study makes use of intravenous acetaminophen , a non-opioid analgesic preoperatively to determine if this will decrease the use of opioids post-operatively for pain management in morbidly obese patients undergoing laparoscopic bariatric surgery.

- Pain relief measured at selected intervals [ Time Frame: 24 hours post surgery ] [ Designated as safety issue: No ]Categorical scale will be used to meaure pain at hours 1,2,4,6 after first dose and then at hour 12, after 2nd dose and hour 18 after third dose and hour 24 after 4th dose.
- Comparison of Recovery room pain management data [ Time Frame: 24 hours post operatively ] [ Designated as safety issue: No ]Use of cumalative PCA and oral morphine use.
- Comparison of patient satisfaction [ Time Frame: 24 hours post-operative ] [ Designated as safety issue: No ]Assessment of patient satisfaction using 4 point scale at each time pain is evaluated post-operatively.
