The purpose of this prospective, randomized, double-blind clinical trial was to compare the efficacy of 1-g doses of intravenous cefazolin with that of 1-g doses of intravenous cefotetan in preventing major operative site infections after elective abdominal hysterectomy. A major operative site infection requiring parenteral antimicrobial therapy developed(More)
Two hundred fourteen women having vaginal or abdominal hysterectomy were entered into a prospective, randomized, blind clinical trial comparing a preoperative intravenous dose of piperacillin to three perioperative intravenous doses of cefoxitin given over an eight-hour period. Interregimen clinical, surgical, and outcome variables of the 207 evaluable(More)
Twenty-one women who underwent radical abdominal hysterectomy and pelvic lymphadenectomy were enrolled in a prospective, comparative, randomized, placebo-controlled clinical trial of antimicrobial prophylaxis. Preoperative endocervical flora was identified and was similar in pre- and postmenopausal private and clinic service women; 46% of the 119(More)
Two hundred and twenty-five women scheduled for elective hysterectomy were entered into a prospective, comparative, randomized, double-blind clinical trial of antibiotic prophylaxis; 117 had vaginal hysterectomy and 108 had abdominal hysterectomy. They were given a 1 gram preoperative dose of ceftriaxone, an investigational cephalosporin or three 1 gram(More)
Fifty women were randomly given one, two, or three 2 gm parenteral doses of cefoxitin with placebo blinding perioperatively at abdominal hysterectomy. A single preoperative intramuscular dose was more efficient, less frequently associated with the development of bacterial resistance, and less expensive than two or three doses.
A retrospective chart analysis of women undergoing elective abdominal hysterectomy in Parkland Memorial Hospital indicated significant postoperative antibiotic administration. For that reason, we conducted a prospective, double-blind, placebo-controlled study to determine the incidence of infection and febrile morbidity in this patient population and to(More)
The practice of administering perioperative antimicrobials to uninfected patients undergoing elective surgical procedures has been subjected to careful prospective investigative scrutiny during the past two decades. A wound classification system was developed, helping to identify procedures for which prophylaxis did not provide benefit to the patient.(More)
Fifty-one premenopausal women were given perioperative intravenous antimicrobial prophylaxis at vaginal hysterectomy in a prospective, blinded comparative study. Febrile morbidity developed in 14 women (27.4 per cent), but only nine (17.6 per cent) required antimicrobial treatment. The incidence of postoperative pelvic infection was 19.2 per cent for 26(More)
The metabolism of cholesterol sulfate (5-cholesten-3 beta-ol sodium sulfate) and cholesterol to pregnenolone sulfate and pregnenolone, respectively, in human fetal adrenal mitochondria has been investigated. Cholesterol sulfate (50 microM) was converted efficiently to pregnenolone sulfate (5-pregnen-3 beta-ol-20-one sodium sulfate; 1.6 nmol min-2 mg-1(More)
A prospective randomized blinded study was conducted comparing a single 2-g preoperative dose of cefoxitin with three 2-g doses of cefoxitin over 12 hours given to premenopausal women scheduled for vaginal hysterectomy in Parkland Memorial Hospital. The incidence of major pelvic infection in 58 women given one dose was 1.7%, and it was 3.7% for 54 women(More)
