Abstract
BACKGROUND: Very limited data are available on the hemodynamic and ventilatory changes during sedation and general anesthesia using bispectral index (BIS) monitoring in intellectually disabled children. The purpose was to determine the hemodynamic and ventilatory changes after propofol and sevoflurane administration in children with special needs (CSN) versus healthy children (HC) during dental treatment. MATERIAL AND METHODS: Forty pediatric patients needing dental treatment were allocated into two groups: children without systemic disease (healthy children [HC]) and mentally disabled children (children with special needs [CSN]). Sevoflurane in oxygen (100% oxygen, 5 l/min) and continuous propofol infusion (target-controlled infusion [TCI], 2 µg/ml) were used as sedative agents, and 2% lidocaine with 1:80,000 adrenaline was used as local anesthesia in both groups. Heart rate (HR), oxygen saturation (SaO2), respiratory rate (RR), exhaled carbon dioxide (CO2), blood pressure (BP) and bispectral monitoring (BIS) values were recorded during the entire dental treatment procedure. RESULTS: A statistically significant decrease in systolic BP, diastolic BP and RR was observed, with no significant differences between the healthy and disabled groups. In contrast, the HR and BIS values were lower in the CSN group than in the healthy patients (p ≤ 0.05). CONCLUSIONS: Patients with special needs had lower HR and BIS values than healthy patients, while BP, SaO2 and exhaled CO2 showed similar results in both groups.
