Evaluation of a TAP Block as Part of an Enhanced Recovery Pathway in Laparoscopic Colorectal Surgery: A Prospective, Randomized, Double-blinded Multi-institution Trial

Detailed Summary

Patients experience pain after surgery mostly from their abdominal wounds, even when those wounds are small. Decreasing that pain has many benefits. It improves comfort, decreases stress response and might improve the outcome of the surgery. Local anesthesia (which is a numbing agent given directly at the site of pain via a needle) is given to decrease the pain that is felt after surgery and decrease the need for strong pain medications which can have negative side effects. One promising way to give local pain medication is called the "transversus abdominis plane" or TAP block. This method works by directly blocking the nerves in the abdomen that are the cause of the pain patients feel in their incision after surgery. This is done by injecting a numbing agent (Bupivacaine) into the area of their abdomen where their nerves are located that cause pain. In the case of nerves that carry sensation, bupivacaine blocks the pain sensation traveling in a particular nerve. Patients will be randomized (like a flip of a coin) to receive either a normal saline injection or the bupivacaine injection. The purpose of this study will be to prove the effectiveness of local anesthetic given via a TAP block in improving postoperative pain, decreasing the use of pain medications, decreasing postoperative nausea and vomiting and improve surgical outcomes such as hospital length of stay in laparoscopic colorectal surgery.
