Brief Summary

Management of neonatal pain and sedation often includes opioid therapy. A growing body of evidence suggests long-term harm associated with neonatal opioid exposure. Providing optimal sedation while neonates are undergoing therapeutic hypothermia (TH) may be beneficial but also presents therapeutic challenges. While there is evidence from animal models of brain injury and clinical trials in adults to support the safety and neuroprotective properties of dexmedetomidine (DMT), there are no published large clinical trials demonstrating safety and efficacy of DMT use in neonates with hypoxic-ischemic encephalopathy (HIE) during treatment with TH. This study is innovative in proposing a Phase II, 2-arm trial providing the opportunity to evaluate the use of DMT as compared to the use of morphine for sedation and pain management for babies undergoing TH. We propose to confirm optimal DMT dosing by collecting opportunistic pharmacokinetics (PK) data and determine safety of DMT in this population. These data will inform a larger phase III efficacy trial.

Arm && Interventions
GroupInterventionDescription
Dexmedetomidine (DMT)Dexmedetomidine HydrochlorideSubjects randomized to DMT arm in a 1:1 ratio. A loading dose of 1 mcg/kg will be given followed by 0.1 to 0.5 mcg/kg/h continuous infusion. The Neonatal Pain, Agitation, and Sedation Scale (N-PASS) will be used to determine infusion rate.
MorphineMorphine SulfateSubjects randomized to morphine in a 1:1 ratio. Intermittent dosing every 3-4 hours of 0.02-0.05 mg/kg/dose or continuous infusion of 0.005 to 0.01 mg/kg/hr. The N-PASS will be used to determine dosing and frequency.
Primary Outcome Measures
NameTimeMethod
Examine Safety Measures in infants receiving DMT to those receiving morphineFirst 96 hours of life

Safety will be evaluated during the first 4 days of life by documenting potential adverse events such hypotension, hypertension, bradycardia, cardiac arrhythmias, hypothermia, acute renal failure, liver failure, and seizures outside of normal range for the study population.

Secondary Outcome Measures
NameTimeMethod
DMT plasma levelsone week

Two opportunistic PK samples (at time of routine laboratories) and a PK sample any time there is an adverse event will be obtained for measurement of DMT plasma concentrations as needed.
