Alcohol

Hypothermia and ethanol are often closely linked and in hypothermic accidents ethanol is often a contributing factor. To study the effects of ethanol on the circulation in hypothermic conditions, cardiac catheterization was carried out on 18 anaesthetized beagle dogs. They were divided into two groups. ⋯ Changes in negative dP/dt coincided with the changes in the time constant of exponential isovolumic pressure fall. Ethanol did not influence relaxation. All the parameters we checked recovered to normal during rewarming.
