title: Comparison of single versus multiple doses of antibiotic prophylaxis in reducing post-elective Caesarean section infectious morbidity.
abstract: BACKGROUND
  Puerperal sepsis is frequently in Caesarean section. Antibiotic prophylaxis may have significant impact in reduction of infections and thus the need to study its role in sepsis prevention systematically.
  
  
  OBJECTIVE
  The aim of this study is to compare the efficacy of single dose versus multiple doses of a first generation cephalosporin (with Metronidazole), to reduce postoperative infectious morbidity in elective caesarean section.
  
  
  METHODS
  It was prospective clinical trial of hundred women undergoing elective caesarean section who received either a single prophylactic dose of Cefazolin with Metronidazole post-cord clamping, or multiple postoperative doses of antibiotics based on the standard protocol of the hospital. Duration of the study was seven months and twenty-two days (11th November 2004 to 30 th June 2005).Women were compared on the basis of development of postoperative febrile morbidity, endometritis, urinary tract infection, wound infection and other infections.
  
  
  RESULTS
  There were no significant differences among the patients in single and multiple dose groups in terms of their age distribution, gravida, period of gestation, smoking status, body mass index, indications for elective caesarean section or operation characteristics. There were 4% and 6% febrile morbidity, 2 (4%) and 0 (0%) urinary tract infection, in the single dose and multiple dose groups respectively. But none of the differences were statistically significant.
  
  
  CONCLUSIONS
  A single prophylactic dose of Cefazolin plus Metronidazole given post-umbilical cord clamping gives as much protection as multiple postoperative doses of Cefazolin/Cefalexin plus Metronidazole in preventing postoperative infectious morbidity in elective caesarean section.
