Conditions: Herniorrhaphy Postoperative Pain Inguinal Hernia
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 50
Healthy volunteers: no

Brief summary:
This study will assess pain intensity for the first 72 hrs after after aggravated movement (cough)following open laparotomy inguinal herniorrhaphy in patient who receive either the CollaRx Bupivacaine implant or a plain collagen sponge.

Detailed description:
Inguinal herniorrhaphy is a common surgery; and common surgical methods used include laparoscopic and open placement of synthetic mesh. The use of synthetic mesh can greatly reduce the risk of hernia recurrence regardless of the method used for its placement. Managing postoperative pain and preventing morbidity after open mesh herniorrhaphy remain considerable medical challenges.

Bupivacaine is a local anesthetic (pain medicine) that has an established safety profile. Collagen is a protein that is found in all mammals. The CollaRx Bupivacaine implant is a thin flat sponge made out of collagen that comes from cow tendons and contains bupivacaine. When inserted into a surgical site, the collagen breaks down and bupivacaine is released at the site but very little is absorbed into the blood stream. The high levels of bupivacaine at the surgical site may result in less pain for several days after surgery.

This study will assess pain intensity after surgery in patients who receive either the CollaRx Bupivacaine implant or a plain collagen sponge.
