All three patients in Hung Nguyen district were severely poisoned by CO gas. After 1 day of treatment, the mother regained consciousness. The hospital transferred all three patients to the provincial General Hospital for treatment with hyperbaric oxygen therapy (HBO) to reduce the incidence and severity of chronic neurological complications after CO poisoning.

Doctor Ngo Nam Hai recommends: “In the cold days, people need to be especially careful with heating devices using honeycomb coal and firewood. Coal burning in conditions of lack of air will create an extremely toxic gas called carbon monoxide, which is very dangerous. Victims who inhale this gas will die in severe cases, and in mild cases, will be left with neurological and mental sequelae.

CO gas is a colorless, odorless and non-irritating gas, so when poisoned, the victim is often unaware. By the time the victim realizes that he or she has been poisoned, he or she is no longer able to call for help. In case the victim is found to have been poisoned by CO gas due to heating with coal or firewood, it is necessary to promptly open the door, ventilate, and take the patient out of the contaminated area as quickly as possible. At the same time, quickly transfer to the hospital for timely emergency care.

At the Department of Emergency Resuscitation and Anti-Poisoning - Vinh City General Hospital, in this cold weather, the Department receives 4-5 stroke cases every day...

Weathercold, the cold weather increases the risk of stroke for the elderly, in addition, some chronic diseases will increase more than normal. The high-risk group is the elderly with a history of diabetes and high blood pressure.

Dr. Nguyen Ngoc Hoa - Director of the Stroke Center shared: Cold weather leads to high blood pressure due to increased activity of the sympathetic nervous system and the renin-agiotensin system. In addition, cold affects hemodynamics by reducing skin perfusion, increasing urine excretion, increasing dehydration, increasing blood concentration... Cold also affects the arteries and heart such as increasing risk factors for cardiovascular disease, increasing atherosclerotic plaque instability, plaque rupture... All of this leads to high blood pressure, myocardial infarction, stroke (cerebral infarction, cerebral hemorrhage).

According to Dr. Hoa: During the cold season, people need to control their lifestyle well to prevent cardiovascular disease and stroke. Specifically, avoid using stimulants such as alcohol, tobacco. Besides, it is necessary to keep the body warm. For those who have the habit of waking up early, exercising (especially the elderly), it is necessary to avoid sudden cold. There are many patients who have stroke, heart attack while exercising in the morning, evening, bathing... due to sudden cold.

Complications of acute pneumonia

The cold air has had a negative impact on the respiratory tract. At Nghe An Lung Hospital and Nghe An Obstetrics and Pediatrics Hospital, the number of patients seeking examination and treatment has increased. For the elderly, common diseases are chronic obstructive pulmonary disease, chronic bronchial asthma, chronic pneumonia, asthma and complications. Because of poor health and reduced resistance, respiratory diseases are often more severe and require longer treatment.

For young children, the main diseases are bronchitis, pneumonia, rhinopharyngitis, severe flu... Some children come to the hospital with their lives threatened by complications of acute pneumonia. During this cold spell, not only young children and infants are sick, but the number of children over 10 years old with respiratory complications at Nghe An Obstetrics and Pediatrics Hospital has also increased.

Doctor Bui Anh Son, Head of the Respiratory Department, Obstetrics and Pediatrics Hospital, recommends: With the cold weather, the number of children who need to be hospitalized for treatment is increasing day by day. In the face of this weather, people need to proactively take measures to protect their children's health, such as wearing enough warm clothes, not letting children go outside, and especially keeping children warm at home.
