In patients undergoing dental treatment or oral surgery who are scheduled to undergo general intravenous anesthesia using remimazolam, we will measure blood levels of remimazolam and its metabolite CNS7054 upon awakening (after completion of remimazolam administration) to determine their pharmacokinetics and to explore factors affecting them.
Pharmacokinetics
Remimazolam blood concentration at various time points after completion of remimazolam administration
- Patient information: age, weight, height, BMI, gender, medical history, medications, and laboratory test results
- Surgical information: operation details, operation time, anesthesia time
- Time from the end of remimazolam administration to extubation (awake time)
- Blood concentration of CNS7054 at each time point after completion of remimazolam administration
- Pharmacokinetic parameters such as AUC (area under the blood concentration-time curve) of remimazolam and CNS7054
- BIS values at the end of remimazolam and at the time of extubation or flumazenil administration
- Remimazolam total dose, average rate of administration
- Remifentanil total dose, mean rate of administration
- BIS values before anesthetic administration, during loss of consciousness, and during maintenance of anesthesia
- Time from remimazolam administration to loss of consciousness
- Number of bolus doses of remimazolam
