Five dogs were cooled externally with ice‐bags to rectal temperatures of 21.8–24.8°C. Rewarming was performed with a specially constructed double‐lumen oesophageal tube with circulating water at 42°C. With this device, rewarming of the dogs to 30°C took place in 60–102 min (mean 82 min). Up to a temperature of 31 °C (the “cardiac safety temperature”), the rise in blood temperature was 4.5°C/h ± 0.79 (s. d.). Calculation of a “rewarming efficiency index” showed an inverse relationship between surface area and temperature rise per hour. The efficiency of this rewarming method is comparable to that of peritoneal dialysis. No afterdrop in temperature was observed and there were no other complications during these experiments. Rewarming with an oesophageal thermal tube is very simple and safe to use.
