Aims Of The Study:
Viper bites produce hematotoxicity and coagulopathy which may be either true disseminated intravascular coagulation (DIC) or DIC-like syndrome. Role of heparin is studied in the present study of viper bite cases as use of heparin provides a rational therapy for defibrination caused by viper envenomation.
Methodology:
One hundred and twenty two patients with viper bite and incoagulable blood were randomised into test group and control group. Test group received heparin in addition to antisnake venom (ASV). Efficacy was assessed by monitoring bleeding time (BT), clotting time (CT), prothrombin time (PT), platelets, fibrinogen, blood urea (BU), serum creatinine, development of complications and overall outcome.
Results:
Heparin group showed favourable outcome in all parameters studied. But many of them were not statistically significant.
Conclusion:
Heparin seems to be having a beneficial role which needs to be confirmed by larger trials and longer duration of heparin administration.
