Table 3.

Dexmedetomidine infusion rates and plasma concentrations for each piglet. The timing of the hypothermia (cooling to 33.5°C; HT), normothermia (NT) and rewarming (RW) phases are shown. The timing of the cardiac arrest and resuscitation are shown for those subjects with these events. The oxygen saturation (O2 sats), heart rate (HR) and mean arterial blood pressure (MABP) for time points corresponding to when dexmedetomidine plasma levels were taken are shown. (BL: baseline)
