Estudo da gestação entre 40 e 42 semanas: avaliação ultrassonográfica, dopplervelocimétrica e resultados neonatais.

Abstract

The present work had the purpose of studying the evolution and neonatal results of pregnancies between 40 and 42 weeks, aiming at evaluating the associated factors to perinatal morbidity in such pregnancies, as well as the importance and effectiveness of propaedeutic methods available for the evaluation of foetal vitality in such situations. To achieve such ending, 38 pregnant women were selected and split in two groups (40th and 41st week), whom were submitted to ultrasound exams (evaluation of respiratory and corporal movements of the foetus, foetal tonus and index of amniotic fluid) and velocity doppler, in addition to the evaluation of variables related to the neonatal results of such pregnancies (way to childbirth, presence of meconium, weight of the newborn at birth, days of internation of the newborn, APGAR, etc.). The study concluded the following results: pregnancies which are prolonged from the 40th complete week are linked to a rise in the indicators of perinatal morbidity and such risk is similar during the course of the 40th to the 41st week; the evaluation of the amniotic fluid volume constitutes important biophysical method for the detection of alterations verified in this group of pacients, whilst the obstetric velocity doppler showed no great usefulness in the monitoring of such pregnancies.
