ABSTRACT
From September 1993 to March 1995 a prospective, descriptive study was performed at Obstetrical Department of the General Hospital 2A the Mexican Institute of Social Security. An attempt to know the real puerperal infection incidence in our own hospital to be able to make hypothesis and take specific measures in puerperal infection control. Dairy account of interesting data of cases under inclusion criteria. Entering data in personal computer. Graphics and analysis were accomplished using Lotus 123, Statgraphics, EPI-6 of CDC and Freelance computational programs. Search of central tendency measures were performed, (media, median, mode, standard deviation). Odds ratio and relative risk were calculated, including hospitalization time and its temporary variation to data cross. X square and pi were including hospitalization time and its temporary variation to data cross. X square and pi were determined to statistic validates. The cumulated rate of general puerperal infection were 1.2%. By stratification, the cumulated rate of infection after cesarean section, vaginal delivery and miscarriage were 5.4%, 0.8% and 0.3%, respectively. There was predominance of infection after cesarean section, over infection after vaginal delivery and after miscarriage. (monthly media of 24.6, 7.3 and 0.47, respectively). The puerperal infection was present principally in primiparous and in patients with one previous cesarean section. The patients in which the termination of pregnancy was by cesarean section, (0.015 infection cumulated incidence), had an infection risk 5.76 and 18.66 times greater than the patients with vaginal delivery and miscarriage. (Relative risk of 6.76 and 19.66) The site of puerperal infection was implicated in combinations or isolated, under nine clinical situation. The five most frequent clinical situation, between these nine, in incidence order from major to minor were the following: Endometritis alone, Endometritis combined with wound abscess. Endometritis with urinary infection, complicated endometritis, (sub vesical abscess, parametritis, peritonitis, salpingitis), and wound abscess alone). The greater hospitalization time was present in cases of complicated endometritis followed by wound abscess alone or combined. Complicated endometritis, (incidence 0.0010), compel us to hysterectomy in 15 cases. No death was registered among the patients with puerperal infection studied.
