Assessing the Effectiveness of Midazolam Premedication

Patients in Group P received midazolam (0.05 mg/kg, intramuscular injection) 30 minutes before induction of general anesthesia.

Target controlled infusion of remifentanil (4ng/ml) was used for induction of anesthesia based on the pharmacological models of Minto. After intubation, remifentanil (2 ng/ml) was infused until incision time. (Both groups)

Target controlled infusion of propofol (4.0 μg/ml) was used for induction of anesthesia based on the pharmacological models of Marsh. After intubation, propofol (3.0μg/ml) was infused until incision time. (Both groups)
