3.7 Emergency Caesarean section
Overall, 278 women had an emergency caesarean section (27.2%), 176/810
(21.7%) women in the low-volume IV fluids group, and 102/213 (47.9%)
women in the high-volume IV fluids group. The unadjusted logistic
regression showed that women in the high-volume IV fluids group were
more likely to have an emergency caesarean section than women in the
low-volume IV fluids group (ORunadj 3.3; 95% CI: 2.4,
4.5). In the adjusted model, emergency caesarean section remained
associated with high-volume IV fluids after adjusting for maternal age,
birth weight, BMI, Intrapartum IV antibiotics for infection/suspected
infection, maternal origin, parity, previous caesarean section, length
of active labour, and model of care
(ORadj 1.99; 95%
CI: 1.4, 2.8) (Table S2). Additionally, women born in South-East Asia
(ORadj 1.5; 95% CI: 1.008, 2.3), duration of active
labour ≥ 12 hours (ORadj 1.6; 95% CI: 1.04, 2.5), and
neonatal birthweight ≥ 4000 grams (ORadj 2.4; 95% CI:
1.3, 4.4) were associated with emergency caesarean section in the
adjusted model (Table S2).
