[The concentration of lactate in amniotic fluid in delivery under physiological course of pregnancy]
Abstract:
The study was carried out to establish admissible range of concentrations of lactate using standard biochemical method in amniotic fluid at first period of delivery under physiologically progressing pregnancy. The sampling included 44 women examined during first period of urgent delivery. The samples of amniotic fluid were taken during the first period of delivery using vaginal amnitomy. The concentration of lactate in samples of amniotic fluid was established using enzymatic amperometric technique. The reference values of concentration of lactate were established in the following admissible limits: 4.4-9.4 mmol per l; ratio lactate/creatinine - 17.7-79.4; ratio lactate/protein - 0.044-0.692. The admissible range of concentration of lactate and ratio lactate/creatinine and lactate/protein in amniotic fluid at first period of delivery under physiologically progressing pregnancy was established.
