Abstract
OBJETIVO: Avaliar o comprimento cervical, por ultrassonografia transvaginal, em pacientes entre 28 e 34 semanas de idade gestacional, correlacionando com o período de latência e o risco de infecção materna e neonatal. MÉTODOS: Foram avaliadas 39 pacientes divididas em relação ao comprimento cervical nos pontos de corte de 15, 20 e 25 mm. Em relação ao período de latência, foram avaliados os parâmetros de 72 horas. Foram incluídas gestantes com feto vivo e idade gestacional entre 28 e 34 semanas, com diagnóstico confirmado na admissão de rotura prematura de membranas. Pacientes com corioamnionite, gestação múltipla, malformações fetais, malformações uterinas (útero bicorno, septado e didelfo), antecedentes de cirurgia prévia no colo uterino (conização e cerclagem) e dilatação do colo maior de 2 cm nas nulíparas e 3 cm nas multíparas foram excluídas no estudo. RESULTADOS: O comprimento do colo <15 mm mostrou-se fortemente associado ao período de latência até 72 horas (p=0,008). O comprimento do colo <20 mm também esteve associado ao período de latência menor que 72 horas (p=0,04). O comprimento de colo <25 mm não apresentou correlação e o período de latência de 72 horas (p=0,12). Não houve correlação entre o comprimento de colo e o período de latência com a infecção materna e neonatal. CONCLUSÃO: A presença de colo curto (<15 mm) mostrou-se relacionada com o período de latência menor 72 horas, porém sem correlação com infecção materna ou neonatal.
PURPOSE: To verify cervical length using transvaginal ultrasonography in pregnant women between 28 and 34 weeks of gestation, correlating it with the latent period and the risk of maternal and neonatal infections. METHODS: 39 pregnant women were evaluated and divided into groups based on their cervical length, using 15, 20 and 25 mm as cut-off points. The latency periods evaluated were three and seven days. Included were pregnant women with live fetuses and gestational age between 28 and 34 weeks, with a confirmed diagnosis on admission of premature rupture of membranes. Patients with chorioamnionitis, multiple gestation, fetal abnormalities, uterine malformations (bicornus septate and didelphic uterus), history of previous surgery on the cervix (conization and cerclage) and cervical dilation greater than 2 cm in nulliparous women and 3 cm in multiparae were excluded from the study. RESULTS: A <15 mm cervical length was found to be highly related to a latency period of up to 72 hours (p=0.008). A <20 mm cervical length was also associated with a less than 72 hour latency period (p=0.04). A <25 mm cervical length was not found to be statistically associated with a 72 hour latency period (p=0,12). There was also no significant correlation between cervical length and latency period and maternal and neonatal infection. CONCLUSION: The presence of a short cervix (<15 mm) was found to be related to a latency period of less than 72 hours, but not to maternal or neonatal infections.
