Summary

The purpose of the study is to evaluate the effect of Exparel on pain control and patient outcome after colon resection. The investigators will evaluate the clinical course of the patients who receive exparel as compared to the patients who do not receive exparel. Exparel is a 72 hour bupivacaine which is slowly released from lysosomes over the course of three days. A long acting local anesthetic should provide better pain control than conventional bupivacaine which has a 3.5 hour half-life.

Detailed description

Patients who are undergoing elective colon resection with Dr. Kraemer and Dr. Raman will be offered participation in the study. This will include robotic, laparoscopic and open procedures. In the pre-operative area prior to surgery, the surgical resident will inform the patient of the opportunity to participate in the research study. The resident will consent the patient at that time, if the patient chooses to participate, they will be randomized to an exparel or non-exparel group. The randomization will be done by having the resident pick an envelope that will state whether or not the patient is randomized to the exparel or non-exparel group, this will randomize to 50% in each group. The patient will not be notified of the type of local anesthetic they receive. The attending surgeon will also be blind to the type of local the pt will receive; only the resident and Operating Room (OR) staff will know what type of local anesthetic was given. Unfortunately the opaque color of the exparel precludes the physician injecting the local anesthetic from being blinded to the type of anesthetic given. The patient will be taken to the operating room as usual, and the surgery will proceed as it normally would. At the end of the surgery the patient will receive either exparel or bupivacaine depending upon which the patient was randomized to. The attending surgeon will not be in the operating suite while the local anesthetic is being injected. 30 milliliters (mL) of either exparel or bupivacaine will be injected into the subcutaneous tissues at the end of surgery. The patient will be taken to the post operative care unit (PACU), the medications for post-operative pain will be standardized between the two groups, a standard starting dose on the patient controlled analgesia (PCA) will be used, and will be adjusted as needed. The postoperative care will attempt to be standardized in regard to diet, discharge (dc) of foley, not using nasogastric (NG) tubes, however this will be based on the individual patient was what is best for their care. This data will then be analyzed to determine if exparel has a beneficial effect on surgical care.
