Cefuroxime prophylaxis in trochanteric hip fracture operations

Area of Science:

• Orthopedic Surgery
• Infectious Disease
• Pharmacology

Background:

• Antibiotic prophylaxis is standard for fracture surgeries.
• Optimizing antibiotic duration is crucial to prevent resistance and reduce costs.
• Previous regimens for trochanteric fractures involved extended antibiotic courses.

Purpose of the Study:

• To compare the efficacy of a 24-hour intravenous cefuroxime regimen with a 24-hour intravenous plus 6-day oral cephalexin regimen for antibiotic prophylaxis.
• To determine if a shorter antibiotic prophylaxis duration is non-inferior in preventing surgical site infections in trochanteric fracture repair.

Main Methods:

• Double-blind, randomized controlled trial.
• Two groups: Group A (24h IV cefuroxime + 6d oral cephalexin), Group B (24h IV cefuroxime).
• Evaluation of infection rates, including deep infections and wound discharge, in patients operated on with nail and plate fixation.

Main Results:

• One deep infection (Staphylococcus aureus) in Group B; 4 patients with discharge (2 S. aureus).
• Six patients in Group A had signs of infection, with negative cultures in 3.
• No statistically significant difference in infection rates between the two antibiotic prophylaxis groups.

Conclusions:

• Antibiotic prophylaxis for trochanteric fractures treated with nail and plate fixation does not require a duration longer than 3 days.
• A 24-hour intravenous cefuroxime regimen appears sufficient for antibiotic prophylaxis.
• Shortened antibiotic prophylaxis may be a safe and effective strategy, potentially reducing antibiotic resistance.
