[Anaphylactoid shocks induced by infusion of a modified gelatin. Six cases (author's transl)].

One of these shocks occurred in course of a rapid infusion in a patient in whom catheters were previously inserted. So, an hemodynamic study was possible. This study shows a peripheral vasodilatation leading to a decrease of preload and cardiac output, and finally to a systemic hypotension which generally raises the alarm. These cases are the first anaphylactoid shocks reported after an infusion of modified gelatin. They demonstrate the general risk of anaphylactoid shock with all types of colloids.
