Rewarming should be started 24 hours after the start of cooling, and should be done slowly, usually over 6 to 12 hours, to prevent the hypotension and rapid shifts in fluid volume and electrolytes associated with vasodilation. The patient’s potassium and glucose levels will likely start to rebound during this phase, so expect
possible decreases in blood glucose and ensure that all potassium containing fluids have been stopped. Discontinue neuromuscular blockade once the patient’s temperature is greater than 96.8° F (36° C),after which sedation can be weaned as well.
