Premature labour with or without preterm premature rupture of membranes: maternal, obstetric and neonatal features - Revista Brasileira de Ginecologia e Obstetrícia
Revista Brasileira de Ginecologia e Obstetrícia. 2015;37(9):428-433
Evaluation of maternal, obstetrics e neonatal features in both spontaneous preterm births (PTB) with or without preterm premature rupture of membranes (PPROM).
Retrospective study of single fetus pregnancies with PTB between 2003 and 2012. Inclusion criteria: PTB associated with ou without PPROM. Exclusion criterias: PTB by medical indication due to fetal/maternal disease and all non accessible or incomplete clinical files. Different characteristics were compared between two groups of PTB: spontaneous PTB without PPROM (sPTB) versus PPROM. Kolmogorov-Smirnov, Levene, χ2, t Student and Mann-Withney tests were used for statistical analysis.
From 2,393 PTB of single fetus, 1,432 files were analysed, from which 596 were sPTB and 836 PPROM. The socioeconomic conditions were similar in both groups. Multiparity (50.7versus 40.3%), personal history of previous PTB (20.8 versus 10.2%), cervical length (18.2 versus 27.2 mm), lower body index mass (23.4 versus 24.3 kg/m2) and higher infectious parameters (Protein C Reactive: 2.2 versus 1.2 mg/L; Leukocytes: 13.3 versus 12.4×109) were more frequent in PBTs (p<0,001). Neonatal outcomes, specially neurologic outcomes (4.7 versus 2.8%, p<0,001), were worst in PBTs.
PTB with or without PPROM has a complex etiology. From all evaluated features in our study, only maternal thinness, multiparity with a previous PTB, the cervical length and worst systemic infections parameters were significant in sPTB. This group also showed worst neonatal outcomes, specially on neurological outcomes.
