Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Mean Umbilical Artery Lactate at Delivery | At delivery | Determined by umbilical artery cord gas collected at time of delivery and only in patients with paired (umbilical artery and umbilical vein) cord gases. |
| Secondary | Umbilical Artery pH | At time of delivery | Determined by umbilical artery cord gas collected at time of delivery and only in patients with paired (umbilical artery and umbilical vein) cord gases. |
| Secondary | Mode of Delivery | At delivery | Delivery via Cesarean section, operative vaginal delivery (forceps or vacuum), or spontaneous vaginal delivery |
| Secondary | Umbilical Artery pCO2 | At time of delivery | Partial pressure of carbon dioxide as collected on cord gases at time of delivery |
| Secondary | Umbilical Artery pO2 | Time of delivery | Partial pressure of oxygen as collected on cord gases at time of delivery |
| Secondary | Umbilical Artery Base Deficit | At time of delivery | As determined by cord gas collection at time of delivery |
| Other | Number of Patients With Resolved Recurrent Decelerations | 60 minutes after randomization | Number of patients with resolution of recurrent variable or recurrent late decelerations within 60 minutes of randomization |
