[Viper bites]

Two cases of bites by the common viper were reviewed. Emphasis was focused on proper medical monitoring in an intensive care unit for a minimum of one day. Observations should include ECG, Hb, leucocytes, electrolytes in both blood and urine, CPK, and coagulation factors. Surgical intervention, heparin and cryotherapy are not recommended. Proper treatment with immobilisation of the bitten extremity, tetanus antitoxin and volume therapy is recommended. In severe cases Zagreb Antitoxin should be used. Patients with cardio-pulmonary problems require special attention.
