Prophylactic antibiotics in hip fractures. A double-blind, prospective study

Area of Science:

• Orthopedic Surgery
• Infectious Disease Prevention
• Pharmacology

Background:

• Fractures of the proximal femur are common injuries.
• Postoperative infections pose a significant risk following orthopedic surgery.
• Antibiotic prophylaxis is frequently used to mitigate infection risk.

Purpose of the Study:

• To evaluate the efficacy of perioperative cephalothin in preventing postoperative infections after proximal femur fracture repair.
• To assess the impact of cephalothin on wound infections, urinary tract infections, and body temperature.
• To identify any adverse effects, such as the development of resistant organisms.

Main Methods:

• A randomized, double-blind study involving 307 patients with proximal femur fractures.
• Patients received either cephalothin or a placebo perioperatively.
• Outcomes measured included rates of major postoperative wound infections, urinary tract infections, and peak body temperatures.

Main Results:

• A significant reduction in major postoperative wound infections was observed in the cephalothin group (4.7% vs. 0.7%, p < 0.05).
• The incidence of postoperative urinary tract infections and mean peak body temperatures were also reduced.
• No significant difference in hospitalization duration or complications related to antibiotic administration was noted.

Conclusions:

• Perioperative cephalothin administration is effective in reducing major postoperative wound infections in patients with proximal femur fractures.
• Cephalothin may also decrease the incidence of urinary tract infections and febrile responses.
• A potential concern is the observed trend towards colonization by cephalothin-resistant organisms, warranting further investigation.
