Surgical Site Infection Rate Drops to 0% Using a Vacuum-Assisted Closure in Contaminated/Dirty Infected Laparotomy
Abstract:
Wound site infections increase costs, hospital stay, morbidity, and mortality. Techniques used for wounds management after laparotomy are primary, delayed primary, and vacuum-assisted closures. The objective of this study is to compare infection rates between those techniques in contaminated and dirty/infected wounds. Eighty-one laparotomized patients with Class III or IV surgical wounds were enrolled in a three-arm randomized prospective study. Patients were allocated to each group with the software Research Randomizer® (Urbaniak, G. C., & Plous, S., Version 4.0). Presence of infection was determined by a certified board physician according to Centers for Disease Control's Criteria for Defining a Surgical Site Infection. Twenty-seven patients received primary closure, 29 delayed primary closure, and 25 vacuum-assisted closure, with no exclusions for analysis. Surgical site infection was present in 10 (37%) patients treated with primary closure, 5 (17%) with primary delayed closure, and 0 (0%) patients receiving vacuum-assisted closure. Statistical significance was found between infection rates of the vacuum-assisted group and the other two groups. No significant difference was found between the primary and primary delayed closure groups. The infection rate in contaminated/dirty-infected laparotomy wounds decreases from 37 and 17 per cent with a primary and delayed primary closures, respectively, to 0 per cent with vacuum-assisted systems.
Insights
Vacuum-assisted closure significantly reduces surgical site infections in contaminated laparotomy wounds compared to primary or delayed primary closure. This technique offers a zero infection rate, improving patient outcomes and reducing healthcare costs.
Area of Science:
- Surgical Site Infections
- Wound Management
- Infection Control
Background:
- Wound site infections following laparotomy increase patient morbidity, mortality, hospital stay, and healthcare costs.
- Current wound management techniques include primary closure, delayed primary closure, and vacuum-assisted closure.
- Optimizing wound closure methods is crucial for reducing infection rates in high-risk surgical wounds.
Purpose of the Study:
- To compare the efficacy of primary closure, delayed primary closure, and vacuum-assisted closure in preventing surgical site infections.
- To evaluate infection rates specifically in contaminated and dirty/infected surgical wounds after laparotomy.
- To determine the optimal wound management technique for reducing complications in Class III or IV surgical wounds.
Main Methods:
- A prospective, three-arm randomized study involving 81 laparotomized patients with Class III or IV wounds.
- Patients were randomly assigned to primary closure (27), delayed primary closure (29), or vacuum-assisted closure (25).
- Surgical site infection presence was assessed by a certified physician using Centers for Disease Control criteria.
Main Results:
- The vacuum-assisted closure group had a 0% surgical site infection rate.
- Primary closure resulted in a 37% infection rate, and delayed primary closure had a 17% infection rate.
- A statistically significant reduction in infection rates was observed with vacuum-assisted closure compared to the other two methods.
Conclusions:
- Vacuum-assisted closure is highly effective in preventing surgical site infections in contaminated and dirty/infected laparotomy wounds.
- The infection rate decreased from 37% (primary) and 17% (delayed primary) to 0% with vacuum-assisted systems.
- Vacuum-assisted closure represents a superior method for managing high-risk surgical wounds to minimize infection complications.
