This study is a descriptive investigation for understanding factors influencing the length of stay in the postanesthesia care unit of elderly patients. Retrospective investigation was conducted on 300 patients aged 65 or older among those who had received an operation under general anesthesia and treated in postanesthesia care unit of hospital C located in Gyeonggi-do, from January 1 to December 31, 2014. The patients' average postanesthesia care unit stay was found to be 48.4 minutes and the 30-59 minute section accounted for the highest part with 58.0%. The postanesthesia care unit stay time according to intra-operative factors showed significant differences depending upon muscle relaxants, transfusion, ABGA, body temperature and total hours under anesthesia. Concerning the post anesthesia care unit stay length according to post-operative factors, significant differences were observed depending upon complications, PCA device, and circulatory drug use. In order to find out factors influencing the post anesthesia care unit stay length, the multiple regression analysis was conducted. As a result, the circulatory drug use and intra-operative lower body temperature were found to have an effect on the post anesthesia care unit stay length with the total explanatory power of 13%. Based on these findings above, it is deemed helpful to carefully monitor factors related to the post anesthesia care unit stay length and provide swift response accordingly for shorter post anesthesia care unit stay time of elderly general anesthesia patients.

Williams syndrome (WS) is a rare congenital disorder which is caused by microdeletion of approximately 1.6 MBP from the long arm of chromosome 7 at 7q11.23. It is characterized by cardiovascular anomalies, elfin face and mental retardation. The most typical oral signs in patient with WS are hypodontia, reduced mesio-distal dimensions both in the primary and permanent teeth, macroglossia, excessive interdental spacing, enamel hypoplasia and enamel hypomineralization. The majority of children with WS have mild to moderate mental retardation, generalized anxiety disorder, hyperactivity disorder and sensitivity to sounds. The purpose of this presentation is to describe dental treatment for a child with WS. A 9-year-old boy diagnosed with WS had caries on his first permanent molars. Because of the poor cooperation, these teeth were filled temporarily with glass ionomer, and treatment under general anesthesia was planned. Under general anesthesia, caries treatment of first permanent molar and extraction of primary molar was successfully performed and there was no postoperative complications related to general anesthesia. Open bite, hypodontia, excessive dental space, enamel hypoplasia, enamel hypomineralization were observed which were characteristic in WS.

소에서는 전신마취보다 전달마취로써 대부분의 수술을 수행한다. 본 연구는 9두의 소에서 요방 1혈(제 1요추 횡돌기의 전단), 요방 2혈(제 2요추 횡돌기 후단) 그리고 요방 4혈(제 4요추의 횡돌기 후단)에 침을 삽입하고 2.0~9.5volt와 주파수 30Hz로 통전하여 각종 수술을 실시하였다. 마취 도입에는 10~25분이 소요되었고, 9두중 7두(78%)에서 전침전달마취만으로, 2두 (22%)는 추가 침윤마취로 수술을 원만하게 완료할 수 있었다. 이상의 결과 소에 대한 전침전달마취는 복강수술을 위해서 특히 poor risk 상태에서는 활용될 수 있을 것으로 생각된다.

Grisel's syndrome is a non-traumatic subluxation of the atlantoaxial joint with an inflammatory condition in the adjacent soft tissues. Due to the instability of the cervical spine, careful airway management is crucial to prevent potential cervical spinal cord injury following airway manipulation. We successfully secured the patient airway using a supraglottic airway device (I-gel) in a patient who had previously diagnosed with Grisel's syndrome. The operation was successfully completed, and the patient recovered without any neurological complications. I-gel can be a good option for airway management during general anesthesia in a patient diagnosed with Grisel's syndrome.

Background: Video-assisted thoracoscopic surgery has become a standard therapy for several diseases such as pneumothorax, hyperhidrosis, mediastinal mass, and so on. These methods usually required single-lung ventilation with double-lumen endobronchial tube to collapse the lung under general anesthesia. However, risks of general anesthesia itself and single-lung ventilation must be considered in high-risk patients. Material and method: Between December 1997 and July 1998, eight high-risk patients (6: empyema, 1: intractable pleural effusion, 1: idiopathic pulmonary fibrosis) with underlying pulmonary disease and poor general condition were treated by video-assisted thoracoscopic surgerys under epidural anesthesia and spontaneous breathing. Result: Video-assisted thoracoscopic surgerys were successfully per formed in 7 patients. Conversion to general anesthesia was required in 1 patient because of decrease in spontaneous breathing. But, conversion to open decortication was not required. In two patients with chronic empyema, one patient required thoracoplasty as a second procedure and one patient required re-video-assisted thoracoscopic procedure due to a recurrence. The mean operative time was 31.8$\pm$15.2 minutes. No significant postoperative respiratory com plication was encountered. Conclusion: Video-assisted thoracoscopic surgerys can be per formed safely under epidural anesthesia for the treatment of empyema and diagnosis of pulmonary abnormalities in high-risk patients.

척추마취는 국소마취제를 지주막하강에 주입하여 척수신경 전근과 후근을 차단하는 방법으로 하복부나 하지 수술 뿐 아니라 만성 통증과 암성 통증의 치료에도 이용되고 있는데 마취시간이나 제통시간의 연장 및 적절한 피부분절의 마취나 진통의 달성은 척추마취에서 중요한 사항이다. 본 연구에서는 morphine정주가 척추마취에 어떤 영향을 주는지 알아보기 위해 척추마취하에서 하지 수술을 받은 40명의 환자를 대상으로 척추마취를 시행한 80분에 척추마취 레벨, 수축기 및 이완기 혈압, 맥박 그리고 호흡수를 조사한후 morphine 10 mg을 정맥내로 주사후 20분후에 척추마취 레벨과 혈압, 맥박, 호흡수를 조사하여 다음과 같은 결과를 얻었다. 1) 척추마취 레벨은 morphine 투여진 $T_{7.5{\pm}0.32}$에 비해 morphine 투여 20분후에 $T_{6.0{\pm}0.31}$로 의의있게 상승하였다 (p<0.005). 2) 수축기 및 이완기 혈압과 맥박수는 morphine투여전과 투여후에 의의있는 변화가 없었다. 3) 호흡수는 morphine 투여전에 비해 투여후 감소가 있었다(p<0.005). 이상의 결과로 척추마취하에서 수술을 시행할 때나 통증치료시 전신적으로 morphne을 투여하여 마취와 진통부위를 넓일 수 있을 것으로 사료된다.

국내에서도 많은 치과의사들이 임상에서 진정법을 시행하고 있으나, 국내에 이와 관련된 지침이 마련되지 않아 임상에서 진정법 시행과 관련하여 어려움을 격기도 하고, 법적인 문제에 휘말리기도 하고 있다. 이에 대한치의학회에서는 치과 진정법 가이드라인을 마련하고자 하고 있다. 이에 참고가 될 만한 미국치과의사협회에서 발간한 진정법 관련 가이드라인을 완역하여 소개한다.

Background: High thoracic epidural anesthesia allows awake coronary artery bypass grafting, avoiding the drawbacks of mechanical ventilation and general anesthesia. Materian and Method: From April, 2005 to September, 2005, 12 patients were underwent awake coronary artery bypass grafting using high thoracic epidural anesthesia. There were 1 female and 11 male patients, with a mean age of $66{\pm}6$ years. Off pump coronary artery. bypass grafting was performed through a median sternotomy using arterial grafts. Result: There were no mortality. Pneumothorax was developed during surgery in 8 patients. Five patients required secondary intubation because of pneumothorax (n=3), bowel herniation (n=1), and hemothorax after chest tube insertion (n=1). Postoperative coronary angiography was performed before discharge in all patients and all the grafts were patent. Conclusion: Our intial experience demonstrated the feasibility of awake off-pump coronary artery bypass grafting. Further study is required to define the indications, advantages and limitations of this strategy.

The excess molar volumes of a general anesthetics on Purple membrane and Red membrane separated by extraction in Halobacteriun Halobium and in suspensions of vesicle have been determined at $25^{\circ}C$, it was used a excess volume dilatometer. The anesthesia characteristics of general anesthetics, Propofol was fined by our study to correlate with excess molar volume. Excess volume changes of the vesicle measured by excess volume dilatometer, which is an important amino acid and lipid in the purple membrane and red membrane by means of specific weight in Halobacteriun Halobium, were studied by absorption intensity at 280 nm and 330 nm. The particle size analysis and relative turbidity of Purple membrane and Red membrane by means of Propofol were measured for mechanical properties. In the samples where Propofol is incoporated in vesicle, especially, the excess molar volume of PM + RM + Propofol is the greatest than the excess molar volumes of PM, and RM.
