Perinatal mortality
deaths
Fresh still birth risk was 43.8 deaths per 1,000 live births: 95% CI (28.3–64.4). Early neonatal mortality risk was: 58.4 deaths per 1,000 live births: 95% CI (40.3–81.4). Perinatal mortality risk was: 102.2 deaths per 1,000 live births: 95% CI (78.1–130.6).The areas under the curve were 0.86 for umbilical arterial lactate, 0.83 for umbilical venous lactate, 0.71 for myometrial lactate, 0.65 for 1 h lactate, and 0.59 for baseline lactate 0.59 for predicting perinatal mortality.
