Introduction: Considering the cost of Anti-Snake Venom (ASV) and irregularity in its supply, there is often a need to curtail doses of ASV, despite guidelines for management of snake bite. During June 2013 to Sept 2013, when ASV was in short supply, our institutional committee reviewed the overall hospital statistics of snake bite cases as well as scientific literature and formulated a working modified protocol that used low dose of ASV in snake bite cases.

Aim: To retrospectively analyse and compare the modified ASV protocol versus conventional ASV protocol with respect to outcome, number of ASV vials required, duration of stay in the hospital/ ICU, and additional supportive interventions needed.

Materials and Methods: This was a retrospective study conducted at a tertiary care teaching hospital, Maharashtra, India. Hospital records of inpatients admitted for snake bite during June 2013 to September 2013 (since introduction of the modified protocol) as well as during June 2012 to September 2012, (when patients received conventional protocol-historical controls) were retrospectively analysed to assess the number of ASV vials received by the patients during the stay, need for supportive therapy, duration of stay and outcome of the patients.

Results: There was a significant reduction in average number of ASV vials per patient, required vide the modified protocol compared to their historical controls (10.74+0.95 Vs 28.17+2.75 p<0.001). There was no significant difference in outcome, need for dialysis, fresh frozen plasma requirement, need for ICU stay and duration of hospitalization of snake bite patients. Yet, the average cost of management of each patient reduced by approximately 11974.41 INR per treated patient, based on the requirement of ASV.

Conclusion: The modified ASV protocol used in this study is more cost effective as compared to the conventional protocol, deserves prospective evaluation and may be followed at least during prime time of scarcity of ASV.
