RESUMEN
@#There have been multiple reports already regarding acute carbon monoxide/CO poisoning in the Philippines secondary to misuse of portable generators, especially during the times of typhoon. We present a case of unintentional carbon monoxide poisoning in a Filipino household wherein three of its members were found dead and leaving other five unconscious before they were rushed to the hospital. The index patient had increased serum fraction percentage of carboxyhemoglobin level and presented with rhabdomyolysis during admission. Neuroimaging confirmed a hypoxic-ischemic encephalopathy secondary to carbon monoxide intoxication. Even without hyperbaric oxygen therapy, patient improved with adequate hydration, early rehabilitation and trauma-focused psychotherapy.
