Prolonged second stage of labour, maternal infectious disease, urinary retention and other complications in the early postpartum period

• ObjectiveTo study the association between duration of second stage of labour and risks of maternal complications (infection, urinary retention, haematoma or ruptured sutures) in the early postpartum period. DesignPopulation-based cohort study. Setting and sampleWe included 72593 mothers with singleton vaginal deliveries at 37weeks of gestation in cephalic presentation, using the obstetric database from the Stockholm-Gotland region in Sweden, 2008-12. MethodsLogistic regression analysis. Odds ratios (ORs) with 95% confidence intervals (95% CI) were calculated and adjustments were made for maternal age, body mass index, height, smoking, cohabitation, gestational age, labour induction, epidural analgesia and oxytocin augmentation. ResultsRates of any complication varied by parity from 7.3% in parous women with previous caesarean section, 4.8% in primiparas and 1.7% in parous women with no previous caesarean section. Compared with a second stage <1hour, the adjusted ORs for any complication (95% CI) in primiparas were for 1 to <2hours 1.28 (1.11-1.47); 2 to <3hours 1.54 (1.32-1.79), 3 to <4hours 1.63 (1.38-1.93) and 4hours 2.08 (1.74-2.49). The corresponding adjusted ORs for parous women without previous caesarean were 2.27 (1.78-2.90), 2.97 (2.09-4.22), 3.65 (2.25-5.94) and 3.16 (1.44-6.94), respectively. The adjusted ORs for women with previous caesarean were for 1 to <2hours 1.62 (1.13-2.32); 2 to <3hours 1.56 (1.00-2.43), 3 to <4hours 2.42 (1.52-3.87), and 4hours 2.31 (1.25-4.24). ConclusionsRisks of maternal complications in the postpartum period increase with duration of second stage of labour also after accounting for maternal, pregnancy and delivery characteristics. Special attention has to be given to parous women with previous caesarean deliveries.
