Randomized Controlled Trial Comparative Study Clinical Trial
[Circulatory changes at the time of anesthetic induction and endotracheal intubation--comparison of thiamylal induction group and propofol induction group].
We examined the circulatory changes after intravenous thiamylal with additional injection of thiamylal 1 minute before intubation and after propofol at the time of anesthetic induction and endotracheal intubation. Sixty ASA I or II patients were studied after the institutional and informed consents. We compared the following three groups. ⋯ But the systolic and diastolic pressures were significantly more stable in Group II and Group III. The change of the RPP was slight and most stable in Group II compared with the other two groups. We conclude that additional injection of thiamylal 4 mg.kg-1 following induction of anesthesia with thyamylal 3 mg.kg-1 1 minute before endotracheal intubation is an effective method for minimizing the increase in blood pressure and circulatory changes at the time of rapid induction of anesthesia and endotracheal intubation.

Randomized Controlled Trial Clinical Trial
[Anesthetic management by continuous total intravenous anesthesia].
Total intravenous anesthesia (TIVA) is one of the most recommended methods of anesthesia for the prevention of air pollution. But the intermittent administration of anesthetic agents has a disadvantage of elongating emergence time. When inexperienced residents undertake TIVA with larger doses of drugs to stabilize vital signs, it takes long emergence time. ⋯ The patients with general anesthesia combined with epidural anesthesia showed longer B time than the patients with only general anesthesia. But there were no differences in Op time and Pr time. We conclude that the continuous TIVA is useful to reduce emergence time and prevent air pollution.

We compared the distance between the upper central incisors and the laryngoscope blade with the four different types of laryngoscope blade (McCoy, Macintosh, Miller, Belscope). Twenty-three patients scheduled for general anesthesia were studied. The tooth-blade distance was measured when optimum visibility of the glottis was obtained. ⋯ The visibility grade was significantly worse with the Macintosh than with the other types of laryngoscope. The results indicate that the McCoy and the Belscope provide less incidence of upper dental injuries and greater visibility than either with the Macintosh or the Miller. Furthermore, the force applied to the handle is thought to be smaller with the McCoy than with the Belscope.

We experienced anesthetic management of a 45-yr-old female patient with a 12-yr history of multiple sclerosis who underwent orthopedic surgeries three times under general anesthesia. We chose rapid induction with propofol and maintained the anesthesia with nitrous oxide, oxygen, and sevoflurane. ⋯ There is no other report of anesthesia using propofol as induction agent for a patient with multiple sclerosis. We succeeded in the satisfactory perioperative management of the patient.

Case Reports
[Anesthetic management of a patient with hypertrophic cardiomyopathy using propofol, fentanyl and ketamine].
A 59-year-old male with hypertrophic cardiomyopathy was scheduled for resection of a maxillary cyst. Metoprolol was discontinued the day before surgery. Thirty min before anesthesia, meperidine 35 mg was administered intramuscularly. ⋯ However, BP, PA, SVRI and PVRI increased temporally at extubation. His postoperative course was uneventful. In conclusion, total intravenous anesthesia with propofol, fentanyl and ketamine may be useful for anesthetic management of a patient with hypertrophic cardiomyopathy.
