I am a general dentist new to midlevel IV sedation. We had a high anxiety patient in need of at least 2 hours of dentistry. As we delivered Versed and 100 ug of Fentanyl, we noticed that the patient was not adequately sedated. Delivering more Versed over a short period of time seemed to agitate the patient more instead of sedating her more. Is anybody able to comment on the side effects of Versed delivered "too rapidly" ? I asked a group of dentists at a meeting who use Versed, and nobody seemed to have an answer. Is anybody able to answer this question???
