To study the planned surgical procedure in single-dose antibiotic prophylaxis

Abstract

Background: Postoperative wound infection may be due to many causes, of which “microbial contamination” is the factor that is influenced by antibiotic administration. Since the concept of antimicrobial prophylaxis has emerged, several workers have searched for optimal antimicrobial drugs, their routes, and the timing of their administration, with the ultimate goal of achieving zero sepsis. The use of preoperative systemic antibiotics has brought down the incidence of wound infection considerably.

Aims and Objectives: The aim is to identify which drug is the best option for single-dose antibiotic prophylaxis to prevent postoperative wound infection.

Materials and Methods: This is a prospective study. The study was conducted in the surgical ward of J.A. Group of Hospitals, Gwalior, Madhya Pradesh, India, from May 2020 to April 2022. Patients of all sexes and ages were included in the study. Patients were divided into five groups according to a class of antibiotics. The study consisted of a total of 125 patients admitted to the surgical ward. Statistical Package for the Social Sciences–(10 systems) was applied for the study. P<0.05 was considered statistically significant.

Results: A total of 125 patients were studied in five groups, depending on the antibiotics. The A, B, C, and D groups were given only a single dose of antibiotics, while group E was given a full course of antibiotics during preoperative, intraoperative, and postoperative periods. Out of 125 cases, only 5 patients had clinical and bacteriological evidence of wound sepsis in different groups of single-dose antibiotics, and one case in group E had multiple doses of antibiotic given. The wound infection rate in clean patients was 20% in ceftazidine, 12.5% with piperacillin tazobactum and cefoperazone sulbactum, and 21.1% in the multiple dose group. No infection was reported with amoxycillin-clavulanic acid. Staphylococcus, Escherichia Coli, and Klebsiella were the offending agents, and anaerobic infections were not found.

Conclusion: A single dose of antibiotic prevents the suppression of normal, sensitive microbial flora, which is usually seen with multiple doses of antibiotics. In this way, it helps in keeping the patients infection-free without interfering with their naturally inherited immunological status of the patient.
