Treatment of cyanide poisoning

Cyanide poisoning: 0.3 mL ampul of amyl nitrite is crushed every minute and vapor is inhaled for 15-30 seconds until an I.V. sodium nitrite infusion is available. Following administration of 300 mg I.V. sodium nitrite, inject 12.5 g sodium thiosulfate I.V. (over ~10 minutes), if needed; injection of both may be repeated at 1/2 the original dose.

Sodium nitrate infusion is limited by hypotension; sodium thiosulfate infusion rate is 2.5-5 mL/minute

Kit: Sodium nitrite 300 mg/10 mL (#2); sodium thiosulfate 12.5 g/50 mL (#2); amyl nitrite 0.3 mL (#12); also disposable syringes, stomach tube, tourniquet and instructions
