Resumo Objetivos: avaliar as taxas de cesárea pela classificação de Robson em 10 grupos (G) e as principais indicações nos grupos prevalentes e no G10. Métodos: estudo transversal, observacional, retrospectivo, incluindo todos os nascimentos em um hospital público do Distrito Federal em 2019. Dados coletados de prontuários eletrônicos e as parturientes categorizadas em dez grupos. Teste qui-quadrado de Pearson para o valor de p e razão de chances comum de Mantel-Haenszel para estimativa de risco, com OR e IC95%. Resultados: ocorreram 2.205 nascimentos, 1.084 (49,1%) cesáreas e 1.121 (50,9%) partos normais. Os principais contribuintes para a cesárea foram G5 (39,3%), G2 (21,2%) e G1 (13,6%). No G10, cesárea teve 51,5% dos nascimentos, não diferindo estatisticamente dos demais grupos (p>0,05). Considerando todos os prematuros, G6 ao G10 e demais grupos, há maior chance de cesárea em relação ao parto normal (OR=1,4; IC95%= 1.011-2.094; p=0,042). Distócia prevaleceu nos G1 e G2, Cesárea prévia no G5 e Síndromes hipertensivas no G10. Conclusão: a cesárea mostrou taxas elevadas inclusive nas primíparas e nos prematuros. Predomínio de Distócia e Sofrimento fetal sugerem melhor avaliação destes critérios diagnósticos, principalmente em G1, G2 e G10.

Abstract Objectives: to evaluate cesarean taxes by looking at Robson classification on 10 groups (G) and the principal indications at the prevalent groups and at G10. Methods: cross-sectional, observational, retrospective study, including all deliveries performed in a public hospital in Distrito Federal in 2019. Data were collected from medical records and pregnant women were classified in 10 groups. Pearson’s chi-squared test was used to calculate the p-value. The risk estimate for cesarean was defined by common odds ratio of Mantel-Haenszel, with calculation of odds ratio (OR) and 95% confidence interval (CI95%). Results: there were 2,205 deliveries, 1,084 (49.1%) of which were cesarean and 1,121 (50.9%) vaginal deliveries. The principal factors for cesarean were G5 (39.3%), G2 (21.2%) and G1 (13.6%). At G10, cesarean had 51.5% of births, not differing statistically from the other groups (p>0.05). Considering all preterm births, G6 to G10 and the other groups, there is a bigger chance of cesarean happening in relation to normal labor (OR=1.4; CI95%= 1.011-2.094; p=0.042). Dystocia remained at G1 and G2, previous cesarean at G5 and hypertensive syndrome at G10. Conclusion: cesarean was most prevalent delivery route, showing elevated rates even in primiparous and preterm births. Preponderance of dystocia and acute fetal distress suggests better evaluation of the diagnostic criteria, mainly in G1, G2 and G10.
