Conclusion
Cyanide poisoning can present with nonspecific symptoms which can complicate the course of diagnosis and rapid therapy. The clinical course can vary from mild to severe. Early recognition of cyanide toxicity can help guide in treatment and improve outcomes. In our case, due to the unavailability of cyanide antidote kits, we chose plasmapheresis beside other supportive measures. Treatment guidance based on a case report is not possible, however, plasmapheresis can be done when standard treatment is not available or the patient is not responding to such therapy.
