NITROUS OXIDE/OXYGEN CONSCIOUS SEDATION IN ASA CLASS II DENTAL PATIENTS – PART 2
Abstract
Aim of the study Patients with comorbidities have often difficulties tolerating in-office dental treatment; therefore, they often require sedation to facilitate dental treatment. When deciding on dental treatment under sedation, the plan should be carefully determined because compared to general patients, ASA Class II patients are more likely to experience complications because of their underlying medical conditions and potential drug interactions. The purpose of this study was to evaluate the Ramsay Sedation Score on nitrous oxide-oxygen mixture conscious sedation in a sample of ASA II patient’s. Material and methods 114 ASA II patients scheduled for elective tooth extraction under local anesthesia were enrolled in this randomized controlled trial. The patients were divided into two groups: the Study group – patients that agreed to receive nitrous oxide/oxygen inhalation sedation (n = 54) and the Control group (n = 60) that included patients unwilling to be sedated. Ramsay sedation scale was used to assess adequacy of sedation. Categorical data are summarized as percentages, and differences between groups were tested using Stata/IC16 software (StataCorp). Ethical approval from the local institutional ethics comitee was obtained for this study. Results There was significant difference after surgery between patients exposed to nitrous oxide/oxygen inhalation sedation and the control group. Conclusions The results of this study show that nitrous oxide/oxygen sedation is a useful method for ASA Class II dental patients, who needs lower doses of sedative to obtain an adequate level of sedation.
