Avoiding Hypotension in Preterm Neonates

Not Applicable
Completed
Conditions
Hypotension
Interventions
Device: NIRS not visible and treatment as usual
Device: NIRS visible and predefined interventions
Registration Number
NCT01910467
Lead Sponsor
Medical University of Graz
Brief Summary

Objectives Firstly to examine in preterm neonates, whether it is possible to reduce number of hypotensive episodes and use of catecholamines by applying cerebral/peripheral near infrared spectroscopy in combination with predefined interventions and secondly to explore the potential impact on cerebral injury and mortality.

Hypothesis By using predefined interventions for changes in cerebral/peripheral oxygenation ratio investigators will reduce hypotensive episodes and use of catecholamines which will reduce cerebral injury and mortality.

Methods Cerebral (cTOI) and peripheral-muscle (pTOI) tissue-oxygenation-index (NIRO 300) will be measured for 24h starting \<6 hours postpartum. When cTOI/pTOI ratio increases \>5% within a 6h period, predefined interventions will be performed.

Primary outcome parameter will be duration of hypotensive episodes and use of catecholamines during the first 48h after birth. Secondary outcome parameters will be cerebral injury and mortality.

NIRS visible and predefined interventionsNIRS visible and predefined interventionsNIRS measurements are visible and the patients will be treated according to predefined clinical interventions: If cTOI/pTOI ratio increases \>5% within a six-hours-period echocardiography will be performed and based on results of echocardiography and blood pressure a volume bolus or, if ventilated, modification of ventilation or treatment of patent ductus arteriosus will be considered.
