3.1 Primary Postpartum Haemorrghage (PPH)
A
total of 339 women had a primary PPH (EBL ≥ 500mL) (33.1%), with
252/810 women (31.1%) in the low-volume IV fluids group and 87/213
(40.8%) in the high-volume IV fluids group. Sixty-four (7.9%) in the
low-volume group and 24 (11.3%) in the high-volume group had a severe
primary PPH (EBL ≥ 1000mL). There was a positive association between
high-volume IV fluids and primary PPH ≥ 500 mL in the univariable
logistic regression (odds ratio [OR] 1.53 95% confidence interval
[CI]: 1.12, 2.09). However, the OR decreased to 1.02 (95% CI: 0.72,
1.44) and statistical significance was not reached in the multiple
logistic regression (Table 3).
