Summary

Opioid medications such as morphine, hydrocodone and oxycodone are standard for treating pain after surgery, however there are disadvantages. Because of the way opioids work, gastric bypass patients may have an increased risk of having sedation or problems with breathing. In patients with sleep apnea, opioids may increase the risk of severe apnea.

Ketamine is an alternative pain medicine that can be used to treat pain after surgery and may have fewer effects on breathing. Using ketamine as part of the regimen may be a better choice for laparoscopic gastric bypass patients.

This study is being done to find out if intraoperative ketamine infusion combined with continuation for twenty-four hours post-surgery provides superior pain control and decreases post-operative opioid use versus standard non-ketamine therapy.
