Study summary

In 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.

Read the detailed description

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.

Study arms

  • Experimental
    artificial contractions (ARTCON) group

    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.

    Drug: Oxytocin

  • Placebo comparator
    standard approach (SA) group

    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.

    Other: Normal saline

Interventions

  • DrugOxytocin

    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.

  • OtherNormal saline

    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.

What researchers measure

Primary outcomes

  1. Incidence of neonatal respiratory morbidity

    Neonatal respiratory morbidity during the first 24 hours after delivery is defined as presence of transitory tachypnoea of the newborn, or respiratory distress syndrome, and/or persistent pulmonary hypertension of the newborn.

    Time frame: First 24 hours after delivery

Secondary outcomes

  1. Oxytocin challenge test effectivity

    Contractions being induced (felt or CTG recorded) before elective caesarean section

    Time frame: Before elective caesarean section

  2. Oxytocin challenge test safety and feasibility

    CTG trace suggestive of hypoxia during oxytocin exposure. Subjectively unbearable pain and discomfort during oxytocin exposure.

    Time frame: Before elective caesarean section

  3. Maternal blood loss

    Defined as the difference in hemoglobin levels before and after surgery

    Time frame: During caesarean section

  4. Total duration of surgery

    Minutes

    Time frame: Time of caesarean section

  5. Lamellar body count in amniotic fluid

    Particles per microlitre

    Time frame: During caesarean section

  6. Incidence of transitory tachypnoea of the newborn

    Breathing rate above 60 per minute at least for 3 hours (3 consecutive measurements) and /or dyspnoea for at least two hours in the follow-up period (consecutive) and /or the need for oxygen therapy during the first 24 hours after birth.

    Time frame: First 24 hours after delivery

  7. Incidence of respiratory distress syndrome

    Defined by need for ventilatory support in the first 24 hours after birth (nasal continuous positive airway pressure, mechanical ventilation) and X-ray examination results consistent with RDS diagnosis.

    Time frame: First 24 hours after delivery

  8. Incidence of perinatal hypoxia

    Presence of diagnostic criteria of hypoxic-ischaemic encephalopathy: 5-min Apgar score of less than 5, need for delivery room intubation or CPR, umbilical cord arterial pH less than 7.00 and abnormal neurological signs such as hypotonic muscles or lack of sucking reflex

    Time frame: First 24 hours after delivery

  9. Incidence of early onset sepsis

    Clinical or proven (positive blood culture)

    Time frame: First 48 hours after delivery

  10. Incidence of significantly increased neonatal pulmonary vascular resistance

    Pulmonary vascular resistance measurements consist of measuring the right ventricular systolic pressure (RVSP), pulmonary artery pressure (PAP) and persistent ductus arteriosus (PDA) shunting (if present).

    Time frame: First 72 hours after delivery

  11. Incidence of persistent pulmonary hypertension of the newborn

    Defined by marked pulmonary hypertension that causes hypoxemia secondary to right-to-left shunting of blood at the foramen ovale and ductus arteriosus.

    Time frame: First 24 hours after delivery
