Abstrakt: Purpose: To analyze the factors related to route of delivery in patients with pre-eclampsia.
Methods: A retrospective analytical study was conducted from January 2009 to January 2011, during which 250 medical records of patients diagnosed with pre-eclampsia who gave birth to live fetuses with a gestational age of 28 weeks or more were selected. The variables evaluated were: maternal age (19 years, 20-34 years and over 35 full years), gestational age at delivery (28-37 weeks and more than 37 weeks), parity (primiparous or multiparous), previous cesarean section, history of pre-eclampsia or chronic hypertension, current diagnosis of mild or severe pre-eclampsia, and birth weight of the newborn. The information was transcribed to a questionnaire based on the variables being investigated. The chi-square test was applied to identify the relationship between the variables, with the level of significance set at p<0.05, and the Odds Ratio (OR) was calculated only for the variables showing a statistically significant difference in order to determine the odds for the patient to be submitted to a cesarean section.
Results: In this study, we observed a 78.4% rate of cesarean delivery, with 54.1% of the patients submitted to the procedure having a gestational age of 28 to 37 weeks (OR=3.1; p<0.01). Patients with a history of pre-eclampsia were 2.5 times more likely to have cesarean delivery (OR=2.5; p<0.02). All patients who had had a previous cesarean were submitted to cesarean delivery in the current pregnancy (p<0.01). Pregnant women with severe pre-eclampsia were 3.3 times more likely to progress to cesarean delivery than those with mild pre-eclampsia (OR=3.3; p<0.01).
Conclusion: After individual analysis, only gestational age and a diagnosis of severe pre-eclampsia showed significant differences, representing risk factors for this type of delivery.
