Ceftriaxone and cefazolin prophylaxis for hysterectomy.
Surgery, Gynecology & Obstetrics
|September 1, 1985
Summary
This study compared two antibiotic prophylaxis regimens for hysterectomy patients, finding both safe and equally effective in preventing infection. Diabetes was identified as a significant risk factor for postoperative infection.
Area of Science:
- Infectious Diseases
- Surgical Prophylaxis
- Pharmacokinetics
Background:
- Hysterectomy is a common gynecological procedure.
- Antibiotic prophylaxis is standard to prevent surgical site infections.
- Comparing different antibiotic regimens is crucial for optimizing patient outcomes.
Purpose of the Study:
- To compare the efficacy and safety of ceftriaxone versus cefazolin for antibiotic prophylaxis in patients undergoing elective hysterectomy.
- To evaluate antibiotic concentrations in surgical tissues.
- To identify risk factors for postoperative infection.
Main Methods:
- Prospective, comparative, randomized, double-blind clinical trial.
- 225 women undergoing elective hysterectomy (vaginal or abdominal).
- Preoperative ceftriaxone versus cefazolin regimens; antibiotic levels measured in serum and tissues.
Main Results:
- Both ceftriaxone and cefazolin regimens were safe, well-tolerated, and equally effective in preventing major postoperative infections.
- Mean ceftriaxone concentrations were higher than cefazolin in serum and various pelvic tissues.
- Diabetes mellitus significantly increased infection risk (p=0.009).
- Vaginal hysterectomy had a significantly lower infection rate (1.7%) compared to abdominal hysterectomy (7.4%, p=0.039).
Conclusions:
- Ceftriaxone and cefazolin are equally effective prophylactic antibiotics for hysterectomy.
- Higher tissue concentrations of ceftriaxone were observed.
- Diabetes and surgical approach (abdominal vs. vaginal) are key factors influencing postoperative infection risk.
