IVH- Intraventricular Hemorrhage Extreme Prematurity Hypoxia Neonatal Hyperoxia Respiratory Insufficiency | Procedure: Delayed Cord Clamping with Low Oxygen concentration Procedure: Delayed Cord Clamping with High Oxygen concentration | Not Applicable |

Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 140 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | Once consent is obtained and the research staff is notified of a subject's impending birth, our research team member will open a randomization card and set the oxygen blender on the special bed to either an FiO2 of .30 or 1.0 and cover the blender. The research team member will not be involved in the clinical care for the infant and will blind the clinical care team from the randomized assignment. |
Primary Purpose: | Prevention |
Official Title: | Delayed Cord Clamping With Oxygen In Extremely Low Gestation Infants |
Actual Study Start Date : | November 17, 2021 |
Estimated Primary Completion Date : | December 1, 2023 |
Estimated Study Completion Date : | June 1, 2026 |

Active Comparator: DCC and Low Oxygen Concentration
During 90 seconds of delayed cord clamping, the infant will receive gentle stimulation and start CPAP by 30 seconds of life at an FiO2 .30, with CPAP of 5 cmH20. If the infant is apneic or there is no Pedicap color change the team will begin positive pressure ventilation (starting PIP of 20 cmH20) by 60 seconds of life. The infant will remain on this support up until the umbilical cord is clamped at 90 seconds or greater. Once the cord is clamped the infant resuscitation will continue according to unit protocol.
|
Procedure: Delayed Cord Clamping with Low Oxygen concentration
During delayed umbilical cord clamping of 90 seconds, breathing assistance with CPAP/PPV and low oxygen concentration (FiO2 0.30) will be provided.

Experimental: DCC and High Oxygen Concentration
During 90 seconds of delayed cord clamping, the infant will receive gentle stimulation and start CPAP by 30 seconds of life at an FiO2 1.0, with CPAP of 5 cmH20. If the infant is apneic or there is no Pedicap color change the team will begin positive pressure ventilation (starting PIP of 20 cmH20) by 60 seconds of life. The infant will remain on this support up until the umbilical cord is clamped at 90 seconds or greater. Once the cord is clamped the infant resuscitation will continue according to unit protocol.
|
Procedure: Delayed Cord Clamping with High Oxygen concentration
During delayed umbilical cord clamping of 90 seconds, breathing assistance with CPAP/PPV and high oxygen concentration (FiO2 1.0) will be provided.
