Use of NIRS in Preterm Population Born at Altitude

Not Applicable

Completed

Brief Summary: Near-infrared spectroscopy (NIRS), is a technology that can provide continuous, non-invasive monitoring of oxygenation in tissue. The objective of this study is to obtain the cerebral regional oxygen saturation (cRSO2) in a preterm population that is born at altitude to determine if the range of "normal" values is different than those obtained at sea level.

Recruitment & Eligibility

Inclusion Criteria

Infant must be <32 weeks' gestational age at time of delivery.
Consenting mother/guardian of the infant must speak English. Other languages are not being included due to the need of a translator being brought into the unit, which adds risk to the vulnerable population. Additionally, as the time to consent is a narrow window, adding the complexity of getting a translator may delay the ability to get consent and thus make it more difficult to enroll patients.
Infants that require blood transfusions during the monitoring time may be included.

Exclusion Criteria

Any known cardiac anomaly or other anomaly which may impair perfusion and blood flow.
Infant born after placental abruption or concern for extreme blood loss immediately after birth.
Unable to consent the mother/guardian due to maternal health issues after delivering (eg requiring intubation or sedation after the delivery).
Mothers/guardians that are prisoners, as the study team would like to have continuing communication with the mother during the study period as needed.
Mothers/guardians that are <18 years of age will not be approached for consent.
Any mother/guardian that is not able to consent due to having a legal representative will not be approached for consent in this study.
Any infant that is planned to be placed for adoption
Infant is greater than 24 hours of age at time of consent.

Arm && Interventions

Group	Intervention	Description
Observational Arm	Near-infrared spectroscopy (NIRS) utilization	Any infant consented to participate in the study will have the NIRS applied for the first 96 hours of life. It will be the goal to apply the NIRS sensors in the first 12 hours of life. All infants will have the same treatment if in the study, but clinicians will not be able to see the data obtained so that there is no clinical interpretation during this time.

Primary Outcome Measures

Name	Time	Method
Cerebral Regional Oxygen Saturation (cRSO2)	first 96 hours of life	Measure cRSO2 for the first 96 hours of life in infants born preterm.

Secondary Outcome Measures

Name	Time	Method
Incidence of Major Complications of Prematurity	From birth until the end of the birth hospitalization, which would be discharge home or death, whichever occurs first. Estimated time is up to 6 months of age.	Additional items recorded to determine if there is any correlation with the cRSO2 values, including death, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, duration of supplemental oxygen required, time to taking full volume feeds via nippling, and hospital length of stay.
