[Evaluation of midazolam intravenous sedated patient's comfort degree in mandibular third molar surgery].

OBJECTIVE: To evaluate the clinical efficacy and safety of continuous low-flow intravenous infusion of midazolam sedation in mandibular third molar surgery. METHODS: Fifty healthy patients with symmetrically placed impacted bilateral mandibular third molars were included in this self controlled, randomized clinical study. Degree of comfort (their actual current anxiety level) was assessed using a visual analogue scale (VAS) of pain and anxiety. Patients' satisfaction and degree of amnesia were also evaluated. Vital signs and oxygen saturation were recorded. RESULTS: Low dose midazolam sedation obviously increased the degree of patients' comfort and satisfaction. Vital signs and oxygen saturation levels did not differ significantly between the two groups. CONCLUSIONS: Midazolam as an intravenous sedation agent in mandibular third molar surgery showed satisfactory effect on patients with mild dental fear.
