# Comparison of the Incidence of Surgical Site Infection in Abdominal Wound Closure: Antibiotic-Coated Polyglactin 910 Suture Versus Polyglactin Suture With Local Infiltration of Antibiotic Along the Incision Line

## TL;DR

This study compares two methods to reduce surgical site infections after abdominal surgery and finds that antibiotic-coated sutures are more effective.

## Contribution

The study provides evidence that triclosan-coated sutures are more effective than local antibiotic infiltration in reducing surgical site infections.

## Key findings

- 20% of Group A (triclosan-coated sutures) had surgical site infections compared to 38% in Group B (local antibiotic infiltration).
- Wound healing rates were high in both groups, with 100% in Group A and 96% in Group B by postoperative day 30.

## Abstract

Aim and objectives

The purpose of this study is to compare the incidence of surgical site infection (SSI) rates in abdominal wound closure utilizing antibacterial-coated (triclosan-coated) suture material versus conventional suture material with subcutaneous antibacterial infiltration along the incision line.

Materials and method

This prospective and comparative (randomized, non-blinded clinical trial) was conducted at the Postgraduate Department of Surgery, Swaroop Rani Nehru Hospital, associated with Motilal Nehru Medical College, Prayagraj, India. The sample size was calculated to be one hundred. The patients in Group A underwent laparotomy using polyglactin 910 coated with triclosan. The patients in Group B underwent normal suture closure and local infiltration of broad-spectrum antibiotics (1 gram of ceftriaxone in 10 ml distilled water, along with the incision).

Results

There was no discernible difference between the various groups on postoperative day (POD) 14, 21, and 30. In Group A, 100.0% of individuals had healed wound status (POD 30). Group B had healed wound status among the 96.0% of members (POD 30). Twenty percent of the people in Group A had SSI whereas 38.0% of the participants in Group B had SSI. There was no discernible difference between the two groups regarding the distribution of culture (χ² = 7.741, p = 0.127).

Conclusion

Triclosan-coated sutures are more effective than subcutaneous antibiotic infiltration along the incision line in lowering the frequency of SSI during primary laparotomy wound closure.
