Single-dose cefazolin prophylaxis for hysterectomy showed similar efficacy regardless of intravenous or intramuscular administration. This randomized trial found route of administration did not impact postoperative infection rates in women undergoing hysterectomy.

Area of Science:

  • Obstetrics and Gynecology
  • Infectious Disease Prevention
  • Surgical Site Infection Control

Background:

  • Limited data exist on single-dose cefazolin prophylaxis efficacy in hysterectomy.
  • No studies have evaluated the impact of cefazolin administration route on surgical site infection (SSI) rates.

Purpose of the Study:

  • To compare the efficacy of single-dose cefazolin administered intramuscularly versus intravenously for preventing SSIs in women undergoing hysterectomy.
  • To identify risk factors for SSIs in abdominal and vaginal hysterectomy procedures.

Main Methods:

  • A randomized clinical trial involving 772 women undergoing elective abdominal or vaginal hysterectomy for benign conditions.
  • Participants received either 1g of cefazolin intramuscularly or intravenously.

  • Infection rates and risk factors were analyzed based on administration route and surgical approach.

    • Main Results:

    • The overall incidence of major operative site infection was 7.2%.
    • Abdominal hysterectomy had a 7.6% infection rate; vaginal hysterectomy had a 6.3% infection rate.
    • Postoperative infection rates were not significantly different between intravenous and intramuscular cefazolin administration.

    Conclusions:

    • The route of cefazolin administration (intramuscular vs. intravenous) does not influence the efficacy of single-dose prophylaxis for hysterectomy.
    • Identified risk factors for SSIs include younger age, lower hemoglobin, and pelvic hematoma for abdominal hysterectomy, and higher body weight and pelvic hematoma for vaginal hysterectomy.
