Prematurity Related Ventilatory Control (PRE-VENT) - Specific Aim 3
To determine if servo-controlled oxygen environment is associated with reduction in (a) bradycardia events, (b) hypoxemic time, (c) bradycardia time, (d) apneic episodes
- Eligible Ages
- Under 98 Days
- Eligible Genders
- Accepts Healthy Volunteers
- Inborn infants weighing 401-1,000 grams on admission and/or 22w 0/7d to 28w 6/7d (<29 weeks) inclusive completed weeks of gestation
Infants eligible for full care and resuscitation as necessary, and surviving beyond 24 h of age
Enrollment in main study protocol (Aim 1 of PreVENT Apnea) at <1 week post-natal age
This study will enroll the subset of infants from Aim 1 who are receiving oxygen supplementation at 32w and 36w PMA, and are not judged too unstable by the Attending neonatologist
Informed consent from parent/guardian
- Refusal or withdrawal of consent Major congenital malformations (e.g., not including patent ductus arteriosus, small hernia)
- Study Type
- Intervention Model
- Crossover Assignment
- Intervention Model Description
- (b) The first 24h of the data collection will be the baseline data. Over the next 72h, we will evaluate 3 interventions in a cross-over manner: Intervention 1 (24-48h of data), Intervention 2 (48-72h), and Intervention 3 (72-96h; same as intervention 1). Initial intervention will be by random assignment (computer-generated). The intervention will be to provide oxygen either by nasal cannula or by servo-controlled oxygen environment, followed by cross-over to other intervention for 24h, and then back to original intervention.
- Primary Purpose
- None (Open Label)
Servo-controlled Oxygen Environment
|Oxygen will be provided by servo-controlled oxygen environment with adjustment of oxygen concentration (FiO2) to keep infant's oxygen saturation target range at 91-95% in a cross-over manner for 24 hours at a time, over a 4-day period, and use Cardiorespiratory Monitoring to evaluate control of breathing.||
Nasal Cannula Oxygen
|Oxygen will be provided by nasal cannula with adjustment of flow rate and FiO2 to keep infant's oxygen saturation target range at 91-95% in a cross-over manner for 24 hours at a time, over a 4-day period, and use Cardiorespiratory Monitoring to evaluate control of breathing.||

This study will enroll the subset of infants enrolled in the main study (PreVENT Aim 1; 401-1000g at birth and/or 22w 0d-28w 6d; enrolled at <1 week postnatal age; eligible for full care and surviving beyond 24 hours, with informed consent; and with no major malformations) who are receiving oxygen supplementation at 32w and 36w postmenstrual age (PMA), and are not judged too unstable by the Attending neonatologist.
For infants on oxygen supplementation at 32w PMA, the investigators will use data from the 96 hours of intensive multiparametric physiologic monitoring at 32w PMA. For infants on oxygen supplementation at 36w PMA, we will use the 96 hours of intensive multiparametric physiologic monitoring at 36w PMA as well as data from the sleep study.
The first 24 hours of data collection will be the baseline data. Over the next 72 hours, the investigators will evaluate 3 interventions in a cross-over manner with the initial intervention (cannula or oxygen environment) randomly assigned: Intervention 1 (24-48h of data), Intervention 2 (48-72h of data) and Intervention 3 (72-96h of data).
