Abstract

Background: The purpose of this study is to investigate the efficacy and safety of the sedation technique for implant surgery by combining the use of inhalation of nitrous oxide/oxygen with intravenous midazolam. Methods: Patients requiring surgery for the placement of dental implants were randomly allocated to two groups receiving intravenous midazolam or a combined technique using nitrous oxide/oxide and intravenous midazolam. Safety parameters, cooperation scores, anxiety scales, total amount of midazolam administered and recovery time were recorded and compared. Results: There were a statistically significant reduction in the amount of midazolam required to achieve optimal sedation (P<0.01), an overall significant reduction in recovery time (P<0.01), a significant reduction in anxiety scales (P<0.05), and a significant improvement in cooperation (P<0.05) and peripheral oxygen saturation (P<0.05) when a combined technique of inhalational $N_2O/O_2$ and midazolam was used. Conclusions: For implant surgery, this combining sedation technique could be safe and reliable, demonstrating reduction of total dose of midazolam and level of patient's anxiety and improvement in patient's recovery and cooperation.
