GASTRIC hypothermia is now used extensively for the management of acute, massive, upper gastrointestinal hemorrhage. It is induced by any one of a number of commercially available machines. They all depend upon the recirculation of a refrigerant solution in a closed system, using some type of balloon in the stomach, through which heat exchange occurs. A predetermined volume of solution is generally used, and temperatures of the solution leaving and returning to the machine are monitored. The efficiency of this type of system is not great because maximum contact between balloon and gastric wall may not be obtained with the volume of solution in use. Furthermore, when larger volumes are used, there is a considerable risk of gastric rupture. The likelihood of rupturing the stomach is greater when the elasticity of the gastric wall is reduced by underlying disease. It can also occur when a smaller volume is added
