[Comparison of Cormack/Lehane classification grades decided by novice residents and those by board certified anesthesiologists].

Background: Tracheal intubation training is one of the most important ones in anesthesia training. But it is difficult to evaluate from the outside whether the laryngeal view obtained with the laryngoscope is appropriate or not.

Methods: We chose a total of 389 cases of tracheal intubation performed by 12 novice residents in 2 months, and compared the grades of Cormack/Lehane classification of the same patients decided by novice residents and board certified anesthesiologists.

[Study of analgestic efficacy of ropivacaine-fentanyl patient-controlled epidural analgesia after upper abdominal gynecological surgery].

Background: Most of the patients who undergo radical or subradical hysterectomy with paraaortic lymphadenectomy suffer from postoperative pain for upper abdominal incision. They also complain of postoperative nausea and vomiting (PONV) frequently, which are increased by opioids.

Methods: Reducing total fentanyl dose to 0.

[Anesthetic management of two patients with Brugada-type ECG and of different clinical severity].

Brugada syndrome is an arrhythmia syndrome characterized by typical electrocardiogram (Brugada-type ECG) and development of ventricular fibrillation (Vf) without any distinct structural heart diseases. The essential goal in the management of Brugada syndrome is to avoid the development of Vf. However, there has been no established consensus on pre-operative risk assessment of patients with Brugada-type ECG.

[Occupational exposure of operating room staff to anesthetic gases during inhaled induction--a comparison with intravenous anesthesia induction].

Background: The risk of occupational exposure to waste anesthetic gases still remains during inhaled induction. In this study we investigated how much we were occupationally exposed to anesthetic gases during induction period.

Methods: Twenty-six adult patients were induced with sevoflurane 5% using a face mask for three minutes and maintained with sevoflurane 1% after end-tracheal intubations (IH-Group).

[Intensive care management of acute pulmonary thromboembolism].

Three patients with acute pulmonary thromboembolism, who had fallen into cardiopulmonary arrest or severe respiratory failure, were treated and saved in our intensive care unit. Two patients were resuscitated with percutaneous cardiopulmonary support device. Two patients underwent surgical embolectomy and we carefully applied positive pressure ventilation to prevent postoperative reperfusion pulmonary edema.
