Official title

Comparative Efficacy of Dexmedetomidine Versus Morphine in Alleviating Secondary Brain Injury, When Used for Sedation During Hypothermia Therapy in Neonates: A Pilot Randomized Trial

Overview

About \~3/ 1000 live-born newborns may suffer from brain injury due to a transient drop in oxygen supply to the brain during the birth process. The degree of brain injury that ensues in the first 72 hours after the injury is directly proportional to the severity of long-term childhood disabilities (e.g., cerebral palsy and developmental delays). Whole-body cooling during the first 3 days of life is proven effective in reducing the severity of brain injury. However, cooling therapy leads to pain, shivering, stress, and discomfort. The best way to alleviate the pain and agitation of cooled newborns is unknown. Standard practice is to provide morphine infusion to reduce pain. Recently, a new drug called "dexmedetomidine" has been tested in small studies and has been found to be safe during cooling in newborns. Dexmedetomidine has added beneficial effects such as anti-inflammation, faster recovery, and shorter hospital stays. This study is going to test the feasibility of conducting a future clinical trial to compare the effects of using Dexmedetomidine versus morphine in the management of cooling-related pain/agitation on the severity of brain injury in the first week of life. The study will also examine the effect of dexmedetomidine compared to morphine on short-term clinical outcomes, parental experiences and developmental outcomes at 1 year.

Interventions

  • Drug Dexmedetomidine Infusion
    Dexmedetomidine infusion given for sedation during therapeutic hypothermia. Dexmedetomidine infusion at a starting dose of 0.2 μg/kg/h, with titration in 0.1 μg/kg/h increments with a maximum of 0.5 μg/kg/h based on objective assessment of sedation.
  • Drug Morphine Infusion
    Morphine infusion given for sedation during therapeutic hypothermia. Morphine infusion at a starting dose of 4 μg/kg/h, with titration in 2 μg/kg/h increments with a maximum of 10 μg/kg/h based on objective assessment of sedation.
