Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Safety, Efficacy

To determine whether intranasal dexmedetomidine (DEX) 2 µg/kg, as an adjunct to standard care, provides lower procedural pain scores during ROP screening compared to placebo in preterm infants born at GA <30 weeks.

Secondary objectives 1

  1. Physiological stability (heart rate, respiratory rate, oxygen saturation, supplemental oxygen requirements, and cardiorespiratory adverse events) during and for 6 hours after IMP administration; Analgesic effect at the time of speculum removal as a secondary measure of pain trajectory; Respiratory support requirements as a measure of respiratory safety; Duration of the first cry episode after ROP screening; Total sleep duration during the first 6 hours after ROP screening; Gastrointestinal tolerability measured by number of vomiting episodes; Cerebral blood flow velocities measured by NeoDoppler before, during, and after ROP screening; EXPLORATORY: Longitudinal blood flow patterns across the NeoDoppler monitoring period; Association between cerebral Doppler velocities and pain scores (PIPP-R); Ophthalmologist's assessment of examination conditions and infant behaviour (VAS).

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1
