According to Dr. Nguyen Trung Nguyen, Director of the Poison Control Center, among these 5 cases, there were 3 cases of poisoning from the kitchen in a house in Hanoi and 2 mothers and children in Nghe An were poisoned by using a generator in a closed room. Notably, the 2 mothers and children in Nghe An were hospitalized with multiple organ damage, especially the brain, heart and respiratory system.

Up to now, after a period of treatment, the mother (48 years old) has regained consciousness and had the breathing tube removed, but the son (15 years old) is still in a coma and in critical condition. "The poisoning cases this time have higher levels of HbCO in the blood than the victims of the fire in Khuong Ha, Thanh Xuan, Hanoi in September 2023," added a representative of the Poison Control Center.

A patient in Nghe An with CO gas poisoning is being treated at the Poison Control Center.

According to Dr. Nguyen Trung Nguyen, the Center has received many cases of CO poisoning that were not caused by fire or explosion, such as: "rotting out" a motorbike in a closed room; running a generator in the bedroom; sitting in a car and being poisoned by inhaling CO from the car's smoke; using a gas-powered water heater; an oil fryer that uses both gas and electricity.

Doctors are looking at an X-ray of a patient's brain damaged by CO2 poisoning.

“CO is a colorless, odorless gas that does not irritate the respiratory tract. Therefore, it is difficult to detect the presence of CO in the air. CO gas is formed by the incomplete combustion of carbon-containing materials such as gasoline, oil, natural gas, wood or charcoal, plastic, fabric, straw, etc. and is absorbed through the skin into the body, then converted into CO gas and causes poisoning,” said Dr. Nguyen Trung Nguyen.

Dr. Nguyen Trung Nguyen warned that up to 50% of patients with mild CO poisoning will still suffer neurological sequelae, dementia, and memory loss after treatment. About 30% of those with severe initial poisoning with cardiovascular damage will die within 8 years due to arrhythmia complications. Furthermore, people over 35 years old with CO poisoning are at higher risk of sequelae. Therefore, early detection and active treatment will reduce the severity, reduce the risk of death, and limit sequelae.
