200In this study, the investigators aim to investigate if artificial uterine contractions prior to elective caesarean section delivery may have an impact on the respiratory morbidity of term neonates.
Accumulating evidence suggests that the respiratory morbidity of infants is lower if delivered by caesarean section after the spontaneous onset of uterine contractions, or after oxytocin exposure. Moreover, benefits for the mother due to stretching of the lower uterine segment and possible lower blood loss are plausible.
In obstetrics, there is a well described and standardized way to induce artificial uterine contractions in order to predict fetal wellbeing and tolerance of labor, without inducing the labor itself. This is the oxytocin challenge test (OCT). Although the OCT has not been performed previously in the context of planned elective caesarean section deliveries, it is generally considered a safe procedure if appropriate monitoring is granted. Hence evaluation of the role of artificial uterine contractions in perinatal respiratory morbidity of term infants delivered by elective caesarean section is possible and of interest.
The intervention group (ARTCON) will receive the standard assignment for the elective caesarean section, but at least one hour before surgery oxytocin exposure will be performed with cardiotocographic (CTG) monitoring and obstetrical supervision.
The control group (SA) will receive the standard assignment for the elective caesarean section, but at least one hour before surgery placebo exposure will be performed with cardiotocographic (CTG) monitoring and obstetrical supervision.
All participating patients in the intervention (ARTCON) group will undergo oxytocin exposure in the form of a continuous intravenous infusion according to dosage guidelines of The Czech Society of Obstetrics and Gynaecology. The exposure will take two hours to complete and should be finished at least one hour before elective caesarean section is performed in order for the assumed effects of physiological stress associated with labor to occur.
All participating patients in the control (SA) group will undergo placebo exposure in the form of a continuous intravenous infusion. The exposure will take two hours to complete and should be finished at least one hour before elective caesarean section is performed.
