Intravenous sedation with midazolam in oral surgery and implantology procedures A retrospective study

The aim of this retrospective analysis was to investigate the intraoperative and postoperative risk of complications associated with intravenous sedation with midazolam in oral surgery and implantology procedures. A total of 231 patients were included in the retrospective analysis. General history, classification according to ASA, type of surgical procedure, initial and total dose of benzodiazepine administered, type and amount of local anesthetic used, duration of sedation and occurrence, vital signs and complications during sedation were documented. Patients aged 12 to 80 years (mean age 36.1 +/- 17.5 years) were 66.2% classified as ASA class 1 and 33.8% as ASA-class 2. In a total of five (2.2%) patients, complications were documented intra-or postoperatively in the context of the i.v. sedation performed. Compared to the complication-free procedures, no significant difference was found in terms of general history, ASA classification, vital signs and in the type or amount of local anesthetic and benzodiazepine. There was a statistically significant difference in body weight between the two patient groups (p < 0.019). The risk of complications associated with i.v. sedation in oral surgery and implantology is low due to adequate patient selection.
