[ECG changes in an adverse reaction to dextran].

The infusion of a few ml of dextran 60 to a 72 years old patient in a spinal anesthesia produced a fall of the blood pressure to 30% of the primary value at constant pulse rate. As the observed raising of the ST part in the ECG is in principle atypical for an anaphylactoid shock reaction, the ECG had at first been misinterpreted and the diagnosis had only been corrected on observation of the dark colour of the skin. After 10 minutes the therapy according to the "AAC-rule" led to an improvement of the circulatory situation, and finally, to complete recovery of the patient. The present case should demonstrate, that also raises of the ST part in the ECG might occur in connection with anaphylactoid shock reactions.
