Mezlocillin single-dose prophylaxis in biliary tract surgery.

Area of Science:

• Surgical Infectious Diseases
• Clinical Pharmacology
• Bacterial Infection Prevention

Background:

• Biliary tract surgery carries a risk of postoperative infections.
• Antibiotic prophylaxis is standard, but optimal regimens require investigation.
• Wound infections are a common complication following abdominal surgery.

Purpose of the Study:

• To evaluate the efficacy of a single preoperative dose of mezlocillin in preventing surgical site infections.
• To assess the impact of mezlocillin prophylaxis on other bacterial complications post-biliary tract surgery.
• To determine the safety profile of single-dose mezlocillin in this patient population.

Main Methods:

• Prospective, controlled, double-blind, randomized multicenter trial.
• 358 patients undergoing biliary tract surgery were enrolled across 12 Swiss hospitals.
• Patients received either 5g mezlocillin or placebo immediately before surgery.

Main Results:

• A significant reduction in wound infection incidence was observed in the mezlocillin group (4%) compared to placebo (10%) (p<0.05).
• No significant difference was found in the rates of other infectious complications between the groups.
• No adverse side effects related to mezlocillin prophylaxis were reported.

Conclusions:

• Single-dose preoperative mezlocillin is effective in reducing wound infections after biliary tract surgery.
• This prophylactic approach is well-tolerated and safe for patients.
• Mezlocillin prophylaxis is recommended for patients undergoing biliary tract procedures.
