Is age a determinant for nausea and vomiting in disabled patients after dental treatment under sedation?

BACKGROUND AND AIM: Postoperative nausea and vomiting (PONV) is one of most frequently encountered problems after dental treatment of mentally and/or motor disabled patients under sedation or general anesthesia. In this study, we aimed to investigate whether PONV incidence in disabled patients differs between adults (>/=18 years) and children/teenage (<18 years). Also investigating complication rates related with anesthesia protocols were additional objectives of the study. MATERIALS AND METHODS: We retrospectively evaluated anesthesia reports of 664 cases undergone different dental treatment procedures under deep sedation with various anesthetic agents. Two study groups (Group 1 consisted from patients with special needs <18 years, while Group 2 consisted from patients >/=18 years) were created. PONV incidence and other complications recorded. RESULTS: There was no statistical difference between groups in terms of used anesthetic agent except midazolam (P < 0.017), while higher female/male ratio and longer duration of anesthesia was recorded in Group 2 (P = 0.043 and P = 0.046, respectively). We found significantly higher PONV rates in disabled patients under 18 years (P = 0.006). Hypoxia (peripheral oxygen saturation (SpO2) <90%) and bradycardia (heart rate <50/minute) were observed in only two patients. CONCLUSION: PONV is more common in disabled patients younger than 18 years and dental treatment procedures under deep sedation can be provided with acceptable complication rates in patients with special needs.
