Clinical Evaluation of Adults Undergoing Elective Surgery Utilizing Intraoperative Incisional Wound Irrigation

A surgical site infection (SSI) is an infection that occurs after a surgical procedure. Despite a variety of infection prevention strategies, SSIs still occur often and impose a significant burden on patients and the healthcare system. Intraoperative irrigation (or washing of the surgical incision before closure) may reduce SSIs, but this is uncertain. The Clinical Evaluation of Adults Undergoing Elective Surgery Utilizing Intraoperative Incisional Wound Irrigation (CLEAN Wound) trial aims to determine if incisional wound irrigation with an antiseptic or salt water solution can reduce SSIs within 30 days of surgery compared to no wound irrigation. 2,500 patients aged 18 years or older who are planned to undergo an abdominal or groin open or laparoscopic procedure will be randomly assigned to incisional wound irrigation with povidone-iodine solution; or incisional wound irrigation with saline; or no irrigation and followed for 30 days after surgery to assess the incidence of SSIs, with additional outcomes collected up to 90 days after surgery. Even with significant advances in medicine over the past decades, there are still many fundamental issues in perioperative care that remain unclear due to lack of evidence. If this trial were to demonstrate that intraoperative wound irrigation reduces the incidence of SSI, these practice-changing findings could greatly benefit patients worldwide.
