Topical ampicillin in the appendicectomy wound: report of double-blind trial

Area of Science:

• Surgical infection prophylaxis
• Clinical microbiology
• Antibiotic efficacy studies

Background:

• Appendicectomy is a common surgical procedure.
• Wound infections are a potential complication following appendicectomy.
• Evaluating preventative strategies for surgical site infections (SSIs) is crucial.

Purpose of the Study:

• To assess the efficacy of topical ampicillin powder in preventing postoperative wound infections after appendicectomy.
• To determine if the degree of appendiceal inflammation affects the outcome of topical ampicillin treatment.

Main Methods:

• A randomized controlled trial involving 130 patients undergoing appendicectomy.
• Patients received either topical ampicillin powder or a topical placebo (lactose) before wound closure.
• Postoperative wound infection rates were compared between the two groups.

Main Results:

• The ampicillin group had a significantly lower wound infection rate (3%) compared to the placebo group (24%).
• The effectiveness of ampicillin was independent of the initial degree of inflammation of the appendix.
• No adverse side-effects were reported in the ampicillin-treated group.

Conclusions:

• Topical ampicillin powder is highly effective in reducing the incidence of wound infections following appendicectomy.
• The prophylactic use of topical ampicillin powder represents a safe and beneficial strategy for appendicectomy patients.
• Further research could explore topical ampicillin use in other surgical procedures to prevent SSIs.
