Lactate level in uterine muscles can be visualized by analysis of amniotic fluid lactase which used as bedside test with partogram to acquire good prediction of labour outcome.
To assess the relationship between amniotic fluid lactase level of full term pregnant women and their mode of delivery.
PATIENTS AND METHODS:
A cross sectional study carried out in Labour room of Al-Yarmouk Teaching Hospital through the period from the 1st of July to the end of December, 2015 on a convenient sample of 100 women of term pregnancy. Each woman participated in the study was in an active phase of labour with cervical dilation > 4 cm and before artificial rupture of membranes .By coscus speculum the cervix was visualized with 2-3 ml of liquor was taken by a syringe while the amniotic fluid still in the uterus to prevent vaginal contamination, then collected liquor in plain tube after centrifuge was stored in refrigerator at -20° for not more than 3 days before it sent to a private laboratory for analysis of lactase.
Mean maternal age was 26.5±5.4 years and mean gestational age was 38.6±1.1 weeks. Thirty three pregnant women had elevated lactase level and 31 women were delivered with cesarean section. A significant association was observed between elevated amniotic fluid lactate level (≥10nm) among pregnant women and cesarean section delivery mode (p<0.001). Amniotic fluid lactate was a significant predictor of delivery mode (p=0.001) with odds ratio (5.5).
Amniotic fluid lactate could be a significant predictor of labour outcome for term pregnant women.
