Baby laryngitis caused by Covid is rare in the world

Ho Chi Minh CityA 6-month-old boy with Covid-19 has laryngitis, edema, blocking the airway, acute respiratory failure; This situation is only a few cases in the world literature.

Doctor Nguyen Minh Tien, deputy director of City Children’s Hospital, said on March 28 that the baby was admitted to the hospital with shortness of breath, cyanosis, chest tightness, SpO2 (capillary blood oxygen concentration) decreased to 82%. Two days before the baby had a low fever, runny nose, cough and hoarse cry, wheezing. Her mother also recently contracted Covid-19.

The child was diagnosed with acute laryngitis, severe respiratory failure and was positive for Covid-19. Doctors gave the baby oxygen, anti-inflammatory, and adrenaline aerosol sprays to combat swelling of the airways. After an hour of intervention, the baby is still having difficulty breathing, so a combination of two types of adrenaline and budesonide aerosols should be used. After 5 days of intensive treatment, the baby’s health has improved, no need for oxygen support, can eat and drink, continue to monitor and treat Covid-19.

According to Doctor Tien, acute laryngitis to the point of respiratory failure in children with Covid-19 is not common, so far City Children’s Hospital has only recorded 10 cases. World literature recorded a few scattered cases. This boy is the most severe complication of respiratory failure, grade 2B; the other children had respiratory failure of grade 1 and 2A, recovered earlier.

The cause of acute laryngitis is usually infection with the parainfluenza virus (parainfluenzae virus), which occurs in children aged 5 months to 3 years, but nCoV can also cause this condition. The doctor suspects that the child may be co-infected with the flu and Covid-19 at the same time. However, Vietnam does not do diagnostic tests for influenza, because flu is less fatal. Therefore, it is not possible to accurately determine the causative agent of acute laryngitis, whether the boy was coinfected with influenza and Covid-19 or not.

The larynx is located in front of the neck, an anterior protrusion, also known as the “forbidden fruit”, has the function of pronunciation. When the larynx is inflamed, the child has a fever, when talking, crying has a hoarse voice, coughing sounds hoarse. If the swelling and edema are much obstructing the airway, leading to difficulty breathing, cyanosis, laryngeal stridor, if inhaled, the child may die if not treated promptly. Therefore, children with fever, cough hoarseness, parents should take them to a medical facility for a doctor to examine to find the cause and timely treatment.
