4 Of these patients only 4 required mechanical ventilation No one required dialysis 1 died

5 Facilities available at the centre ICU care 1 mechanical ventilator Blood components for transfusion available from Blood Bank about 35 km away from Dehradun Laboratory tests like Prothrombin time and Partial Thromboplastin test and other biochemical tests

6 Protocol for Snake bite management Paediatric department follows CMC, Vellore and Secondary hospitals mordified version of W.H.O protocol Medicine department projected 2 different versions of care

7 2 different versions of treatment Version 1 – according to senior resident Version 2 – according to other residents Lab tests at presentation BT/CT, Bld. Urea, S. Creatinine, WBCT, Urine microscopy Lab tests at presentation not mentioned

8 Indications for ASV Version 1 Version 2 Mild/moderate signs and symp – lymph edema, lymphangitis, enlarged lymph nodes, blister and edema at site of bite, bleeding from sight of bite. Sever / generalised signs and symptoms – hemolysis, ptosis, respiratory depression, head lag, prolonged WBCT Mild/moderate symp and signs – cellulitis involving half of bitten limb, rapid progression of edema, bleeding from site of bite, lymphadenopathy, 20 min WBCT Severe signs/ symp – DIC, Hypotension, ARF, Neurotoxicity

9 Treatment of mild/moderate symptoms Version 1 Version 2 For both hematotoxic and neurological bites – 5 vials ASV over 1 hour. Repeat 20 min. WBCT in 30 min. after the dose If WBCT is pronged or if neurological signs/ symp. Repeat 5 vials in 6 hours 5 vials are continued every time for 6 hours if WBCT is pronged or if there are signs of neurotoxicity. For both types of bites a maximum of 20 vials ASV are given For mild/moderates toxicity – 3 vials loading dose over 1 hour. Reassess and repeat WBCT. Then 3 vials are repeated over 4 hours.
