Is this trial a fit for you?

Likely a good fit

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

Probably not a fit

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

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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