RIC in HIE: A Safety and Feasibility Trial

No results posted yet for this study

Summary

Remote Ischemic Conditioning has never been studied in neonates with HIE. However, RIC has been studied in animal models of perinatal asphyxia and has shown encouraging results. In neonatal rats with HIE, RIC is associated with reduced sensory motor deficits compared to non-RIC, and repeated cycles in three consecutive days is superior to a single treatment. In piglets, four cycles of 10 minutes of bilateral hindlimb ischemia immediately after bilateral common carotid occlusion results in reduced cell death in the periventricular white matter and internal capsule. These preclinical studies support the hypothesis that RIC may be beneficial in infants with HIE.

Conditions

  • Hypoxic-Ischemic Encephalopathy

Interventions

DEVICE

Remote Ischemic Conditioning

Patients randomized to the RIC arm, cohorts of 4 consecutive patients will receive escalating therapy: A. 4 consecutive patients will undergo 4 cycles of 3 minutes ischemia, followed by 5 minutes reperfusion, on Day 1 of therapeutic hypothermia B. Observing no safety events (see below) from patients in group A, 4 consecutive patients will undergo 4 cycles of 5 minutes ischemia, followed by 5 minutes reperfusion, on Day 1 of therapeutic hypothermia. C. Observing no safety events from patients in group B, 4 consecutive patients will undergo 4 cycles of 5 minutes ischemia, followed by 5 minutes reperfusion, on Days 1 and 2 of therapeutic hypothermia. D. Observing no safety events from patients in group C, 4 consecutive patients will undergo 4 cycles of 5 minutes ischemia, followed by 5 minutes reperfusion, on Days 1, 2, and 3 of therapeutic hypothermia. All infants will have an extra 1ml of blood collected.
