The Comparison of Blood Pressure and Heart Rate Changes with Extubation of the Endotracheal Tube and the Laryngeal Mask Airway / 대한마취과학회지

When the endotracheal tube is removed, blood pressure elevates and heart rate increases. In order to evaluate the hemodynamic changes after removal of a new developed device-laryngeal mask airway, we measured the change of the systolic & diastolic blood pressure and heart rate of 120 patients undergoing general anesthesia. The results were elevation of blood pressure and heart rate after extubation or removal on both groups immediately. But the degree of changes were 18.7+/-1.6% in the endotracheal tube groups and 12.3+/-1.4% in the laryngeal mask airway groups in systolic blood pressure respectively. Therefore the degree of changes of the laryngeal mask airway groups was significantly small (p<0.05). The comparison of the change of diastolic blood pressure was not significant. The degree of the change in heart rate was 19.6+/-2.8% in the endotracheal tube groups and 9.2+/-2.2% in the laryngeal mask airway groups. Therefore the degree of the ehange in blood pressure and heart rate of the laryngeal mask airway groups was significantly small (p<0.05).

Intraoperative Radiation Therapy of locally Advanced Gastric Cancers: Case report / 영남의대학술지

Stomach cancer is the most popular tumor in Korea but the prognosis following extensive surgery and chemotherapy has not improved for many years. Conventional external radiotherapy also has some limitation, namely, a cancerocidal dose cannot be delivered to tumors because of low radiation tolerance of adjacent critical sensitive organs. In order to overcome these limitations of curative surgery and external radiotherapy, intraoperative radiotherapy was proposed in many centers and the results were excellent. We treated two cases of locally advanced gastric cancers with IORT by using NEC 18 MeV Linear Accelerator after standard subtotal resection of the stomach. After treatment, the patients are in good conditions so far, but in order to evaluate the effectiveness of IORT, a study will be performed on the survival rates between patients treated by IORT and those treated by surgery alone.

Ambulatory Anesthesia / 대한마취과학회지

An imaginative innovation to shorten hospital stays as a means to reduce patient charges, is out-patient surgery. This procedure also minimized the inconvenience and disruption of the family unit, reduced the opportunities for cross-infection, and freed hospital beds for the more seriously ill patients Since the concept of out-patient surgical service was organized, managed, and performed in the Hanyang Medical Center, we had experience of 132 ambulatory anesthetics during the last two years (from Jan. 1974. to Dec. 1975 ). The results are summarized as follower 1. Preanesthetic examination should be routinely checked with Hb., Hct., urinalysis and chest x-ray. 2. Premedication should be administered preanesthetically, atropine sulfate intravenously. 3. ASA class 1 patients should be chosen for short (less than 1 hour) procedures. 4. Anesthesia is induced with Epontol+S.C.C. and maintained with Halothane+N2O+O2. 5. We suggest that ambulatory anesthesia should be more carefully planned, organized, and managed.
