Monitoring carbon dioxide levels in newborns with brain injury receiving cooling treatment

Transcutaneous Carbon Dioxide Monitoring in Neonates Receiving Therapeutic Hypothermia for Neonatal Encephalopathy

Observational Brigham and Women's Hospital · NCT04603547

This study is testing a new way to monitor carbon dioxide levels in newborns with brain injury who are receiving cooling treatment to see if it works as well as the usual methods.

What this trial studies

This study evaluates the feasibility of using transcutaneous carbon dioxide monitoring (tcPCO2) in neonates undergoing therapeutic hypothermia for neonatal encephalopathy. It aims to quantify the agreement between tcPCO2 and traditional PCO2 measurements in this vulnerable population, which may include infants with or without respiratory support. Given the high incidence of hypocarbia in these patients, the study seeks to optimize their intensive care and potentially improve neurodevelopmental outcomes. The research is particularly significant as tcPCO2 has not been systematically evaluated in this context before.

Who should consider this trial

Good fit: Ideal candidates for this study are neonates with neonatal encephalopathy who are admitted for therapeutic hypothermia.

Not a fit: Patients with major birth defects or those in extremis with a focus on palliative care may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance monitoring techniques and improve outcomes for infants with neonatal encephalopathy receiving therapeutic hypothermia.

How similar studies have performed: While the use of tcPCO2 monitoring is common, this specific application in neonates with encephalopathy undergoing hypothermia has not been previously tested.
