Background: General anesthesia is preferred when prolonged and multiple dental procedures are required in the pediatric population. In children in whom neuromuscular blockers (NMBs) are contraindicated, dental treatments can be performed under deep sedation, but there is increased risk of respiratory complications such as hypoxia and foreign body aspiration.
Case Report: In the case report, due to rocuronium allergy detected during the preoperative evaluation process, the application of nasal positive pressure ventilation support allowing prolonged deep sedation with complete immobilization was presented.
Conclusion: Prolonged deep sedation using a nasal CPAP mask can be used as an alternative to general anesthesia during dental procedures, especially in patients with contraindications to NMBs. In this way, it would be possible to reduce the risk of hypoxia and hypercarbia with ventilatory support while providing total immobility with deep sedation.
