Brief Summary
This is a pilot study in a randomized, controlled, double-blinded format and will evaluate the ability of a local anesthetic, Ropivacaine, to decrease pain after gastric bypass surgery. The drug will be administered into the abdomen during a bariatric bypass surgery. After surgery, patients who received Ropivacaine will be compared to those without Ropivacaine to determine its effect on reducing pain, recovery of lung function, ability to walk, and quality of life during recovery.

Study Arms (2)
Intraperitoneal Normal Saline
PLACEBO COMPARATORIntraperitoneal Normal Saline: 100mL (Milliliter) normal saline administered as in intervention arm
Intraperitoneal ropivacaine
EXPERIMENTALThe abdomen will be entered and trocars placed in the usual manner. Using a standard suction/irrigation device and tubing, 200mg of Ropivacaine (0.2% Ropivacaine in 100mL Normal Saline) will be instilled into the abdomen at the start of the case, prior to dissection as follows. Under direct visualization, 50mL (Milliliter) (of the 100mL) will be infused over the esophageal hiatus. The remaining 50mL will be infused throughout the abdomen. The infusion line will then be flushed with 30mL (Milliliter) of Normal Saline to ensure the entire treatment dose is delivered, and no Ropivacaine remains in the tubing. The remainder of the surgery will proceed as usual.
Interventions
Eligibility Criteria
You may qualify if:
- Patients undergoing Roux-en-Y gastric bypass surgery;
- Patients who able to tolerate general anesthetic and pneumoperitoneum;
- Patients who able to provide informed consent for the surgery;
- Patients over the age of 18 years;
You may not qualify if:
- Patient undergoing planned Sleeve Gastrectomy (inta-op conversion to Sleeve Gastrectomy after delivery of intraperitoneal ropivacaine will be included and analyzed using intention-to-treat approach)
- Patients with an allergy to local anesthetics
- Patients with severe underlying cardiovascular disease (ie: congestive heart failure, conduction abnormalities, and ischemic heart disease)
- Patients with chronic renal disease Stage 3 or greater (Creatinine clearance less than 60mL/hr (millilitre per hour))
- Patients with hepatic dysfunction Child-Pugh Class B or C
- Patients with previous foregut surgery including esophageal, gastric, liver, and pancreas resections
