The optimal dosage and ideal infusion rates are unknown. Keep in mind that pre-existing chronic premature ventricular contractions may be suppressed during hypothermia and recur during rewarming. Moreover, the majority of hypothermia-induced dysrhythmias convert spontaneously during rewarming. You order an infusion of Bretylium in 50 cc of fluid over 10 min.

Heat is conducted directly to the intraperitoneal abominal and posterior parietal structures.
Heat is also conducted through the posterior parietal peritoneum. A double catheter system can be used to increase the rate of rewarming with suction at the outflow. Infuse 2 liters, retain for 20 to 30 minutes, and then aspirate. Beware of abdominal adhesions from previous surgeries. The good news is that this method allows direct detoxification of associated drug ingestion and rhabdomyolysis.
