Title: Surfactant Positive Airway Pressure and Pulse Oximetry Trial (SUPPORT) in Extremely Low Birth Weight Infants
Brief Summary: This study compared the use of continuous positive airway pressure initiated at birth with the early administration of surfactant administered through a tube in the windpipe within 1 hour of birth for premature infants born at 24 to 27 weeks gestation. In addition, these infants within 2 hours of birth, had a special pulse oximeter placed to continuously monitor their oxygen saturation in two different target ranges (85-89% or 91-95%). This study helped determine whether or not these two management strategies affect chronic lung disease and survival of premature infants.


Options:
A: Inclusion Criteria:

* Gestational age of 27 to 31 6/7 weeks,
* Postnatal age between 15 and 60 minutes,
* Supplemental oxygen requirement or evidence of increased work of breathing (tachypnea, intercostal retractions, nasal flaring, or grunting), and
* Prenatal consent.

Exclusion Criteria:

* Apgar score less than 2 at 5 minutes,
* Intubation prior to randomization,
* Prenatal diagnosis of major congenital anomalies,
* Prolonged rupture of membranes of greater than 3 weeks duration, and
* Infants who were likely to be transferred to another center soon after birth were not enrolled in the study.
B: Inclusion Criteria:

Infants likely to be delivered to women presenting to a participating Vermont Oxford Network Center at high risk of premature delivery at gestational age 26 + 0 to 29 + 6 weeks will be eligible for inclusion. Specific inclusion criteria that must be met prior to randomization include:

1. Imminent delivery
2. No potentially life-threatening congenital anomaly or genetic syndrome
3. No known lung maturity
4. Antenatal steroid status known
5. Written, informed consent obtained (on admission or prior to delivery).

Exclusion Criteria:

1. Stillborn (Apgar score of 0 at one minute of age)
2. Noted to have a potentially life-threatening congenital anomaly or genetic syndrome noted immediately after delivery.
C: Inclusion Criteria:

* Infants with a minimal gestational age of 24 weeks 0 days to 27 completed weeks (up to 27 6/7ths) by best obstetrical estimate
* Infants who will receive full resuscitation as necessary, i.e., no parental request or physician decision to forego resuscitation
* Infants whose parents/legal guardians have provided consent for enrollment, or
* Infants without known major congenital malformations

Exclusion Criteria:

* Any infant transported to the center after delivery
* Infants whose parents/legal guardians refuse consent
* Infants born during a time when the research apparatus/study personnel are not available
* Infants \< 24 weeks 0 days or \> 28 weeks 0 days, completed weeks of gestation
D: Inclusion Criteria:

* Preterm neonates with a gestational age (GA) of 25+0 - 28+6 completed weeks.
* Inborn neonates.
* In case of twins, both neonates will be included in the same treatment arm.
* Parental written informed consent for participation in the study obtained on admission into the hospital or prior to delivery.

Exclusion Criteria:

* Evidence of severe birth asphyxia, that is an APGAR score below 3 at 5 minutes of age.
* Need for endotracheal intubation for cardiopulmonary resuscitation or insufficient respiratory drive.
* Known genetic or chromosomal disorders.
* Delivered to mothers with ruptured membranes of more than 3 weeks duration.
* Potentially life-threatening conditions unrelated to immaturity.
* Participation in another clinical trial of any placebo, drug, biological, or device conducted under the provisions of a protocol.
