title: [Advantages and hazards of preventing infection following cesarean section--clinical and bacteriologic results of a high-dosage treatment with mezlocillin and oxacillin short-term preventive following clamping of the umbilical cord].
abstract: Between August 1980 and August 1981 a prospective randomised study was conducted at the Krankenhaus Nordwest , Dept. of OBGYN , Frankfurt, to investigate the efficacy of a short term prophylaxis using mezlocillin and oxacillin ( Optocillin ) in reducing infections after Caesarean section (6 gs Optocillin after clamping the umbilical cord and after 8 and 16 hours, respectively). Both the study group (sg) and the control group (cg) consisted of 50 patients each. Both groups were statistically homogeneous . Infections were significantly reduced by the prophylaxis: sg 26%/cg 64% - p less than 0,001, febrile morbidity: sg 10%/cg 38% - p less than 0,001, endometritis: sg 6%/cg 20% - p less than 0,08, UTI: sg 18%/cg 36% - p less than 0,05, wound infections: sg 2%/cg 18% - p less than 0,02. Severe infections, however, were seen in neither group. The duration of infections was shorter in the sg. The various postoperative infections were associated with different risk factors (rf) - endometritis: green amniotic fluid, operating time greater than 75 min; cervical dilatation less than 2 cm, UTI: PROM (greater than 6 hs), operating time less than 75 min, internal monitoring, cervical dilatation greater than 2 cm, wound infections: green amniotic fluid, internal monitoring, frequent vaginal examinations (greater than 6), cervical dilatation greater than 2 cm and operating time greater than 75 min. The prophylaxis was especially effective in the presence of the following rfs: green amniotic fluid, internal monitoring, frequent vaginal examinations (6), operating time greater than 75 min and when associated with combined rfs. The reduction of wound infections following the prophylaxis can be ascribed to the elimination of organisms (Staph. spec., enterococci,) at the site of operation.(ABSTRACT TRUNCATED AT 250 WORDS)
