Association between risk pregnancy and route of delivery with maternal and neonatal outcomes - Revista Brasileira de Ginecologia e Obstetrícia
To analyze the relationships among gestational risk, type of delivery and
immediate maternal and neonatal repercussions.
A retrospective cohort study based on secondary data was conducted in a
university maternity hospital. A total of 1606 births were analyzed over a 9-month
period. Epidemiological, clinical, obstetric and neonatal characteristics were
compared according to the route of delivery and the gestational risk characterized
on the basis of the eligibility criteria for high clinical risk. The occurrence of
maternal and neonatal complications during hospitalization was analyzed according
to gestational risk and cesarean section delivery using univariate and
multivariate logistic analysis.
The overall rate of cesarean sections was 38.3%. High gestational risk was
present in 50.2% of births, mainly represented by hypertensive disorders and fetal
malformations. The total incidence of cesarean section, planned cesarean section
or emergency cesarean section was more frequent in pregnant women at gestational
high risk (p<0.001). Cesarean section alone did not influence maternal outcome,
but was associated with poor neonatal outcome (OR 3.4; 95%CI 2.7-4.4). Gestational
high risk was associated with poor maternal and neonatal outcome (OR 3.8; 95%CI
1.3-8.7 and OR 17.5; 95%CI 11.6-26.3, respectively). In multivariate analysis, the
ratios were maintained, although the effect of gestational risk has determined a
reduction in the OR of the type of delivery alone from 3.4 (95%CI 2.7-4.4) to 1.99
(95%CI 1.5-2.6) for adverse neonatal outcome.
Gestational risk was the main factor associated with poor maternal and neonatal
outcome. Cesarean delivery was not directly associated with poor maternal outcome
but increased the chances of unfavorable neonatal outcomes.
