RIC in HIE: A Safety and Feasibility Trial

"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."
