Intranasal midazolam conscious sedation for dental surgery in child with left ventricular noncompaction

Left ventricular noncompaction (LVNC) is a recently described rare type of congenital cardiomyopathy with a poor long-term prognosis. We performed dental extraction for a 6-year-old female patient with LVNC who had risk of endocarditis due to dental disease along with a history of being uncooperative with dental care. For this case, we utilized intranasal (IN) midazolam conscious sedation, which enables a rapid sedation onset and is considered appropriate for child patients with a high level of anxiety, as movement is effectively decreased, making dental surgery possible. In cases with a small number of teeth, IN midazolam conscious sedation provides a safe condition for high-risk or anxious children undergoing treatment.
