ABSTRACT

Aim

The aim of this study was to evaluate the features of inhalation conscious sedation for urgent dental treatments in
uncooperative paediatric patients during COVID-19 outbreak.

Methods

Forty-two uncooperative patients,
attending primary and secondary schools, were submitted to emergency dental treatments with inhalation conscious sedation using
nitrous oxide and oxygen during COVID-19 pandemic. Collected data included: number of working sessions, success/failure, adverse
events, side effects, number of teeth treated; type of dental procedure. Parents filled in an e-mailed questionnaire on post-discharge children status to evaluate: pain; crying; fever; vomiting; headache; drowsiness; excitability; irritability; ability to eat; need for drugs.

Results

One working session was carried out in 29 patients, 2 working sessions were carried out in 6 patients and 3 working
sessions were carried out in 7 patients. Success rate was 87.1%. In relation to success, there was no statistically significant difference between males and females, healthy and disabled patients, respectively; while there was a statistically significant difference between patients attending primary and secondary schools (p=0.023). No adverse events occurred. The most frequent side effect was nausea. In relation to side effects, there was no statistically significant difference between males and females, healthy and disabled patients, patients attending primary and secondary schools, respectively. In relation to e-mailed questionnaires on post-discharge children status, 29.6% of the patients had pain, 22.2% vomited, 14.8% had headache, 18.5% experienced drowsiness, 29.6% failed to eating normally, 35.2% needed to take drugs. None of the patients cried, had a fever, exhibited irritability and excitability.

Conclusion

Inhalation conscious sedation is a safe, practical and effective procedure with minimal side effects to perform emergency dental treatments in uncooperative paediatric patients during COVID-19 outbreak.
