Trial Summary
What is the purpose of this trial?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.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.
What data supports the effectiveness of the treatment Intraoperative incisional wound irrigation with povidone-iodine solution for preventing surgical site infections?
Research shows that using povidone-iodine solution for wound irrigation during surgery significantly reduces wound infections compared to using saline, with a lower infection rate of 2.9% versus 15.1% in one study.
12345Is wound irrigation with povidone-iodine or saline safe for humans?
Wound irrigation with povidone-iodine and saline is generally considered safe for humans, though povidone-iodine can sometimes cause skin irritation if misused. Saline is widely regarded as a safe and cost-effective option for wound irrigation.
13467How does intraoperative wound irrigation with povidone-iodine or saline differ from other treatments for surgical site infections?
Intraoperative wound irrigation with povidone-iodine is unique because it significantly reduces the incidence of surgical site infections compared to saline irrigation, especially in clean-contaminated wounds, by using an antiseptic solution that kills bacteria. This method is particularly effective in reducing infections in various types of surgical incisions, unlike some other treatments that may not show significant benefits without additional antibiotics.
13458Eligibility Criteria
This trial is for adults over 18 who are scheduled for certain abdominal or groin surgeries and have health insurance in Ontario. It's not for those with active infections, extremely dirty surgical sites, or allergies to povidone-iodine.Inclusion Criteria

Irrigation of subcutaneous tissue with povidone-iodine solution for prevention of surgical wound infections. [2017]Five hundred patients undergoing a variety of general surgical operative procedures were prospectively randomly allocated into a treatment group, in which the incisions were irrigated with povidone-iodine solution prior to skin closure or into a control group in which wounds were irrigated with saline solution. Wounds were classified according to the degree of bacterial contamination as clean, potentially contaminated, contaminated or dirty. For all categories of surgical incisions, povidone-iodine irrigation resulted in a significant decrease in wound infections over that for saline solution irrigation. Over-all incidence of wound sepsis in the treatment group was seven of 242 patients, 2.9 per cent, compared with the control rate of 39 wound infections of 258 patients, 15.1 per cent--p less than 0.001.
Povidone-iodine irrigation of the subcutaneous tissue to prevent surgical wound infections. [2017]In a prospective randomized trial, the influence of irrigation of the subcutaneous tissue using povidone-iodine solution upon the development of postoperative wound infection was examined in 592 patients undergoing general surgical operative procedures. No beneficial effect of irrigation with povidone-iodine solution could be demonstrated, nor could it be demonstrated in the group as a whole or in the subgroups according to bacterial contamination.
Aqueous Povidone-Iodine Versus Normal Saline For Intraoperative Wound Irrigation on The Incidence of Surgical Site Infection in Clean-Contaminated Wounds After Gastroenterological Surgery: A Single-Institute, Prospective, Blinded-Endpoint, Randomized Controlled Trial. [2023]This trial evaluated the superiority of intraoperative wound irrigation (IOWI) with aqueous povidone-iodine (PVP-I) compared with that with saline for reducing the incidence of surgical site infection (SSI).
Prevention of Surgical Site Infection Following Open Spine Surgery: The Efficacy of Intraoperative Wound Irrigation with Normal Saline Containing Gentamicin Versus Dilute Povidone-Iodine. [2023]Intraoperative wound irrigation (IOWI) is an important step in preventing surgical site infection (SSI). This study compared the effectiveness of saline with gentamicin versus povidine-iodine (PI) as IOWI solutions in preventing SSI in open spine surgery.
Ineffectiveness of povidone-iodine irrigation of abdominal incisions. [2017]Two to four percent of uncontaminated surgical wounds become infected; the incidence is increased in contaminated cases. The present study was designed to determine the efficacy of wound irrigation with povidone-iodine in patients not receiving prophylactic antibiotics who were undergoing gynecologic operations. The results revealed no significant difference in the relatively high occurrence of wound infections, morbidity, and elevated fever indices between the povidone-iodine wound irrigation group of patients and the control group. From a review of previous studies of topical antibiotics and antiseptics in contaminated cases as well as from the present findings, providone-iodine wound irrigation without assocaited use of prophylactic antibiotics does not appear to reduce significantly the incidence of wound infections in patients with potential vaginal contamination.
Povidone-iodine induced post-surgical irritant contact dermatitis localized outside of the surgical incision area. Report of 27 cases and a literature review. [2017]Povidone-iodine solution is an antiseptic that is used worldwide as surgical paint and is considered to have a low irritant potential. Post-surgical severe irritant dermatitis has been described after the misuse of this antiseptic in the surgical setting.
A Review of Surgical Irrigation Solutions for Infection Prevention in Orthopaedic Surgery. [2023]» Intraoperative surgical irrigation is a common practice in orthopaedic procedures, although there is no universally established standard of care due to a lack of concrete data supporting an optimal irrigation agent.» Isotonic normal saline has long been considered a safe and cost effective solution for wound irrigation as compared with other antibiotic and antiseptic irrigation solutions.» Currently, the only adjunct to saline that is formally supported by American Academy of Orthopaedic Surgeons, the Centers for Disease Control and Prevention, and World Health Organization is povidone-iodine.» Further in vivo clinical studies are needed to identify the ideal irrigation solution that carries low cytotoxic effects while also exerting optimal antimicrobial properties.
A trial of povidone-iodine in the prevention of infection in sutured lacerations. [2019]A prospective, randomized study of 500 consecutive emergency department patients with traumatic lacerations requiring sutures was performed comparing use of topical 1% povidone-iodine (Betadine) and scrubbing with wound management by irrigation with normal saline without scrubbing. A 60-second wound irrigation and scrub with a 1% povidone-iodine solution was the only difference in treatment between the two groups. Data relating to risk factors such as age; degree of contamination; type of closure; ethanol intoxication; mechanism of injury; and bone, joint, or tendon involvement were analyzed. Wounds were classified as clean, infected, or purulent at follow-up examination. One hundred five patients were lost to follow-up. Of the 395 remaining patients, 122 were contacted by phone and were classified based on their description of the wound; 273 were classified at reexamination in the ED. Of 201 povidone-iodine group wounds, 11 became infected; two of them (5.4%) were purulent. Of 194 control wounds, 30 became infected, of which 12 (15.46%) were purulent (P less than .01). These data suggest that use of a topical 1% povidone-iodine solution in traumatic lacerations prior to suturing reduces the incidence of wound infections.
