Purpose: to evaluate the effects of ascending infection on the mother and newborn in the cases of premature rupture of membranes. Methods: this was a prospective study, carried out to evaluate 50 pregnant women with premature rupture of membranes (PROM) and their newborns. The clinical chorioamnionitis was investigated by clinical findings (thermal curve, abdominal pain by groping and/or uterine softening, smell and other characteristics of vaginal secretion) and subsidiary tests (white blood cell count and C-reactive protein). The histologic chorioamnionitis was investigated by macroscopic and microscopic study (placenta, membranes and cord). In the microscopic study optic microscopy with hematoxylin-eosin staining was used. The newborns were evaluated as to weight and Apgar score in the first and fifth minutes of life. White blood cell count, culture of auditory canal swab and aspirated gastric material culture complemented the study. Statistical analysis was performed using the Fisher exact test and the Student t-test, with level of significance set at 5% (p < 0.05). Results: The rate of clinical chorioamnionitis was 29.4% (15/50), while for histologic chorioamnionitis it was 40% (20/50). All the cases of clinical chorioamnionitis had latency times (LT) higher than 24 hours. The newborns presented signal of infection in 31.4% of the cases (16/51), all with LT higher than 24 hours. The main isolated microorganisms of auditive duct and gastric aspirate of newborns were Klebsiella pneumoniae, Staphylococcus aureus, Gram positive coccus and group B Streptococcus. The infected newborns presented lower Apgar scores in the first and fifth minute of life, lower weight and higher perinatal morbidity and mortality when compared with newborns without infection. Conclusions: based on the analysis of results obtained in the present study, it was possible to conclude that the prolonged latency times increase the possibility of ascending infection, leading to higher possibility of premature delivery and high maternal morbidity (clinical chorioamnionitis), as well as perinatal morbidity and mortality.
