[Circulatory survival of irreversible comas].

On the basis of a series of 53 cases of irreversible coma maintained in circulatory survival with the aim of removing the kidneys, the authors discuss the mode of treatment, with particular reference to the intravenous fluids used and the use of medications influencing the circulation. Fluid and electrolytes given must be adjusted hourly to ensure the exact replacement of urinary losses. Isoprotenerol is the only medication usually necessary. In the event of circulatory insufficiency, which is difficult to foresee and hence prevent, immediate volume expansion in a short a time as possible and isoprotenerol most frequently correct the situation (14 out of 17 cases). Thus effective circulation may be maintained until the kidneys are removed (48 out of 53 cases). 92 p.cent of the grafted kidneys functioned from the first day onwards.
