Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
This is an observational trial of cerebral oxygen kinetic and haemodynamic responses in newborn infants <30 weeks gestation following administration of indomethacin or ibuprofen for haemodynamically significant ductus arteriosus.
Treatment of a patent ductus arteriosus is a clinical decision prior to study inclusion. Once enrolled in the study newborns will receivin either ibuprofen (20mg/kg) or Indometacin (0.2mg/kg).
Babies enrolled in the trial will have a number or observations and measurements.
1.regional cerebral tissue oxygen saturation - data to be collected continuously from baseline up to 6 hours after medication infusion. Additional data will be captured for 30 miutes between 20 and 26 hours after medication administration.
2. Internal Carotid blood flow - measured by serial pulsed-wave Doppler ultrasound before, 5, 30 mins, 4-6 hours and 20-26 hours after medication administration.
3. Arterial blood gas - taken before, 5, 30 min, 4-6 hours and 20-26 hours after medication administration.
These measures will be used to calculate cerebral oxygen kinetic variables including delivery and consumption.

Outcomes
Primary outcome [1] 306363 0
i. Comparison of cerebral oxygen kinetics using either indomethacin or ibuprofen with direct comparison at each time point
Cerebral oxygen kinetics will be assessed using the following measures:
1: Near-infrared spectroscopy derived regional tissue oxygen saturation (rS02)
3: Co-oximetry derived arterial oxygen saturation (Sa02)
2: ultrasound derived internal carotid blood flow
3: Arterial blood gas measures - Haemoglobin, Pa02
From this, cerebral oxygen delivery, consumption and extraction will be calculated.
This is a composite primary outcome
