A Comparative Study of Intra-Incisional Antibiotic Infiltration and IV Prophylaxis in Reducing Pfannenstiel Wound Infections
Abstract
Background: Surgical site infections (SSIs) following Pfannenstiel incision procedures remain a significant clinical challenge, with reported incidence rates of 5-20% despite systemic antibiotic prophylaxis. The anatomical location and frequent contamination from genitourinary flora make this incision particularly vulnerable to infection.
Objective: To compare the efficacy of three antibiotic administration strategies in preventing SSIs: conventional intravenous (IV) prophylaxis, intra-incisional infiltration, and a combined approach.
Methods: After taking ethical approval from the concerned institute, a prospective, triple-arm, randomized controlled trial was conducted at a tertiary care hospital from January to September 2021. Three hundred patients undergoing Pfannenstiel incision procedures were randomized to receive: Group A: IV ceftriaxone 1g, - Group B: Intra-incisional ceftriaxone 1g and Group C: Combined IV 500mg + intra-incisional 500mg ceftriaxone
Results: The intra-incisional group demonstrated superior outcomes with SSI rate of 6% vs 13% in IV group (p=0.024), Shorter mean hospital stay (3.1 vs 4.2 days) and Lower postoperative pain scores (VAS 3.1 vs 4.7). Microbiological analysis revealed Escherichia coli as the predominant pathogen (51.7%).
Conclusion: Intra-incisional antibiotic administration significantly reduces SSI risk and improves postoperative outcomes compared to IV prophylaxis. This method should be considered as a standard approach for Pfannenstiel incision procedures.
