Purpose: To evaluate the safety of midazolam and diazepam for adolescents during third molar extraction and whether any differences in perioperative complications exist when using the 2 benzodiazepines alone or in combination.
Materials and methods: A prospective study was performed in adolescents (<21 yr old) who underwent at least 1 third molar extraction by an oral and maxillofacial surgeon in the ambulatory setting from January 2001 through December 2010 using the Oral and Maxillofacial Surgery Outcomes System. The primary predictor variable was type of benzodiazepine used, divided into the total number of patients who received diazepam with or without midazolam. The outcome of interest was adverse complications resulting from anesthesia. Multivariable logistic regression was applied to measure the association between benzodiazepine type and adverse complications.
Results: Patients in the diazepam group (n = 4,213) and in the combination group (n = 426) had a complication rate of 1.4%, whereas those in the midazolam group (n = 13,451) had a complication rate of 1.0% (P = .027). Multiple logistic regression analysis showed a 50% increased odds of adverse complications in patients receiving diazepam (adjusted odds ratio = 1.50; 95% confidence interval, 1.05 to 2.16; P = .027).
Conclusions: Adolescent patients who received intravenous diazepam during third molar procedures had an increased odds of anesthesia-related complications compared with those given midazolam.
