COVID-19 and Dysphagia in Children: A Review

Coronavirus (COVID-19) infection usually causes mild symptoms in children. However, serious complications may occur as a result of both acute infection or in association with the multisystem inflammatory syndrome (MIS-C). Dysphagia may develop as a sequela of COVID-19. We review the limited data on dysphagia associated with COVID-19 infection in children. Children can develop acute respiratory distress syndrome (ARDS) due to severe COVID-19 infection leading to endotracheal intubation and mechanical ventilation. These children can possibly develop post-intubation dysphagia. Screening for the presence of dysphagia, in an effort to minimize aspiration, in children with active COVID-19 infection must be done carefully to reduce the risk of transmission of the virus. Those children diagnosed with persistent dysphagia after COVID-19 infection has resolved will need further evaluation and management by pediatric subspecialists experienced in treating children with this condition. We recommend, this evaluation and treatment be done by a pediatric aerodigestive team.

Postintubation Dysphagia During COVID-19 Outbreak-Contemporary Review

The COVID-19 is a global pandemic. Its rapid dissemination and serious course require a novel approach to healthcare practices. Severe disease progression is often associated with the development of the Acute Respiratory Distress Syndrome and may require some form of respiratory support, including endotracheal intubation, mechanical ventilation, and enteral nutrition through a nasogastric tube. These conditions increase the risk of dysphagia, aspiration, and aspiration pneumonia. The data on the incidence and risks of dysphagia associated with COVID-19 are not yet available. However, it is assumed that these patients are at high risk, because of respiratory symptoms and reduced lung function. These findings may exacerbate swallowing deficits. The aim of this review is to summarize available information on possible mechanisms of postintubation dysphagia in COVID-19 patients. Recommendations regarding the diagnosis and management of postintubation dysphagia in COVID-19 patients are described in this contemporary review.

Tracheal tubes lubricated with water to reduce sore throat after intubation: A randomized non-inferiority trial

Background

Sore throat is common after tracheal intubation. Water can be used to lubricate tracheal tubes, but its benefit has not been validated. We thus did a randomised non-inferiority trial to test the hypothesis that a tube lubricated with water does not reduce sore throat after tracheal intubation.

Methods

We randomized female or male patients (n = 296) undergoing surgery in the ears or eyes to receive either a tube lubricated with water or a tube without lubrication for intubation. We assessed sore throat at 0, 2, 4, and 24 h after surgery; pharyngeal injury at 2 and 24 h after surgery; and respiratory infections within 7 days after surgery. For the incidence of sore throat within 24 h after surgery (primary outcome), the two-sided 90% confidence interval of the risk difference was compared with the prespecified non-inferiority margin of 15%. Other outcomes were analyzed with two-sided superiority tests.

Results

The incidence of sore throat within 24 h after surgery was 80/147 (54.4%) in the non-lubricated tube group and 83/149 (55.7%) in the water-lubricated tube group (risk difference -1.3%, 90% confidence interval -10.9% to 8.3%). Because the confidence interval was below the non-inferiority margin, the incidence of sore throat was not higher in the non-lubricated tube group than in the water-lubricated tube group. There was no significant association between groups in the sore throat, pharyngeal injury, and respiratory infection at each assessment time.

Conclusions

The tube lubricated with water did not reduce sore throat and pharyngeal injury after tracheal intubation compared to the tube without lubrication.
