OBJECTIVE:

Analyze cesarean sections according to Robson's classification in peruvian public hospital.

MATERIALS AND METHODS:

Analytical cross-sectional study in 64375 deliveries attended at the Hipolito Unanue hospital in Tacna according to Robson´s classification. Cesarean rates, absolute and relative contribution, cesarean sections´ indications and maternal perinatal risks were compared in two periods (2000-2009, 2010-2018). Chi2 was used with statistical significance when p <0.05 and Odds Ratio (OR) with 95% Confidence Interval (95% CI) with significant risk when IC> 1 and p <0.05. The data was obtained from the Perinatal Informatic System and processed in SPSS version 25.

RESULTS:

The overall cesarean section rate was 38.6% with an increase of 23.9% in 2000 to 55.8% in 2018; a predominance of groups 1, 3 and 5 who had greater absolute and relative contribution. The main indications were cephalopelvic disproportion, fetal distress, previous caesarean section and preeclampsia. There was a significantly higher risk of neonatal death in groups 1 (OR = 2.6, 95% IC: 1.28-5.39, p <0.05) and 3 (OR = 3.1, 95% IC: 1.62-5, 79; p <0.05) compared with vaginal deliveries.

CONCLUSIONS:

The cesarean rate increased in the last 19 years, mainly in groups 1, 3 and 5 according to Robson&apos;s classification; Group 1 and 3 presented a greater risk of neonatal mortality compared with vaginal deliveries.
