a clinical scoring system for dose requirement for AScVS is evolved based on sweating, pulse rate, respiratory rate, blood pressure, CNS effects and presence of priapism. Computed doses were given according to clinical grading as intravenous bolus slowly.

Prazosin therapy Prazosin (30 micrograms/Kg/dose): 500 micrograms for pediatric patient, and 1mg for adult patients) will be given every 3 hourly orally till complete recovery.

Combination AScVS and Prazosin therapy In this group, AScVS therapy will be given as mentioned in AScVS therapy group and in addition, prazosin (500 micrograms for pediatric patient and 1mg for adult patients,30 micrograms/Kg/dose) every 3 hourly will be given.

Scorpion Envenomation

AScVS therapy group
If the score is 5 and if the patient belongs to pediatric group(>12-14): 1 vial AScVS as i.v. slow bolus after test dose If the score is 5 and if the patient is adult: 2 vials of AScVS as i.v. slow bolus after test dose. For injection, 1 vial will be dissolved in 10 ml distilled water and given over a period of 4 to 5 minutes.
According to the scores 1 vial for pediatric and 2 vials for adult patient will be increased as shown below:
