We have experienced 25 cases of aortic aneurysm from October 1987 to January 1996. Patients ranged in age from 26yrs to 73yrs(mean age 52.5yrs). There were 13 males and 12 females. Eighteen cases were thoracic aneurysm and seven were abdominal aneurysm. The cause of aneurysm were dissecting in 16cases aneurysms and non-dissecting in 9 cases. Risk factors of aortic aneurysm were hypertension, hypercholesterolemia, Marfan's syndrome. In thoracic aneurysm patients, 12 cases of dissecting aneurysm underwent aneurysmectomy and replacement of vessel interposition graft with or without coronary artery implantation on the graft. 6 cases of non-dissecting aneurysm underwent operation with same policy as dissecting aneurysm. In 7 case of abdominal aneurysm,all patients underwent aneurysmectomy and graft interposition with straight or Y graft. There were 5 postoperative death(mortality 20%). Several cases of complications were improved with proper managements. All survivors showed improvement in clinical symptom and sign and discharged without specific complications.

Background:
Although dental sedation helps control anxiety and pain, side effects and serious complications related to sedation are gradually increasing. Due to the introduction of new drugs and sedation methods, insurance rates, legal regulations, drugs, and methods used for dental sedation are inevitably changed. In the Republic of Korea, National Health Insurance is applied to all citizens, and this study investigated changes in the use of sedatives using this big data.
Methods:
This study used customized health information data provided by the Healthcare Insurance Review & Assessment Service of Korea. Among patients with a record of use of at least one of eight types of sedatives for dental sedation between January 2007 and September 2019 were selected; the data of their overall insurance claims for dental treatment were then analyzed.
Results:
The number of patients who received dental sedation was 786,003, and the number of dental sedation cases was 1,649,688. Inhalational sedation using nitrous oxide (N2O) accounted for 86.8% of all sedatives that could be claimed for drugs and treatment. In particular, it was confirmed that the number of requests for sedation using N2O sharply increased each year. Midazolam showed an increasing trend, and in the case of chloral hydrate, it gradually decreased.
Conclusion
According to our analysis, the use of N2O and midazolam gradually increased, while the use of chloral hydrate gradually decreased.

BACKGROUND: Recently, patients' demands for emergency medicine are increasing, and most of prehospital medical care, including basic life support, cardiopulmonary resuscitation and triage, are provided by paramedics or emergency medical technicians. Evaluation of the adequacy of prehospital management and triage has become important for improving the quality and the effectiveness of the emergency medical system. METHODS: The 202 patients who were transferred by ambulance with paramedics, nurses, or emergency medical technicians to the Emergency Department in Gil Medical Center from July 1, 1999, to September 31, 1999, were enrolled. This study was conducted prospectively by using the emergency physician's log and newly devised protocols recorded by paramedics or nurses. RESULTS: 1) Male to female ratio was 1:0.8, and the peak age of the patients were the 4th(18.8%) and 6th decade(15.3%). 2) Of the 202 patients, 84 patients were transferred for trauma and 118 for medical problems. The mean transfer time was 6+/-1.73 minutes. 3) The validities of prehospital triage and decisions using the trauma severity measure and the disease severity measure, were 33.3% in trauma patients and 57.6% in medical patients. 4) The results for the adequacy rate in prehospital management analyzed by using the rate of necessity of treatment, performance of treatment, and adequate treatment were as follows: oxygen supply, 38.1/41.6/93.8; wound dressing, 19.3/71.8/92.9; immobilization of the cervical spine, 15.8/56.3/92.9; application of a spinal board, 12.9/42.3/72.7; application of a splint, 9.9/50.0/60.0; manual maintenance of an airway, 9.9/55.0/63.6; and CPR, 4.5/66.7/0.5) Kind of ALS(Advanced Life Support) were not conducted(peripheral IV, EKG, intubation medical administration, defibrillation, pacing). The rates of necessity of treatment were as follows: peripheral IV, 40.6%; ECG monitoring, 23.3%; endotracheal intubation, 8.9%; medical administration, 8.9%; defibrillation, 3.5%; and pacing, 1.5%. CONCLUSION: The adequacy of prehospital triage and decisions using trauma and disease severity measures was relatively low. To improve the adequacy of BLS(Basic Life Support) and to increase the performance of ALS(Advanced Life Support), we must create challenges to develop new protocols and to supplement new equipment.

We have experienced 66 cases of video assisted thoracic surgery(VATS) of spontaneous pneumothorax. The patients ranged in age from 15years to 46years(mean age, 22.3years) and male patients were sixty three. The indications of video assisted thoracic surgery of spontaneous pneumothorax were recurrence, continuous air leakage, visible blebs on the chest X-ray and others. Infraoperative findings were as follows; blebs, pleural adhesion and pleural effusion. The operation was performed under general anesthesia with double lumen endo- bronchial tube. Operative procedures included blebectomy and/or wedge resection of lung, vibramycin pleurodesis with mechanical abrasion. In most cases, postoperative courses were uneventful and patients were discharged without significant complications. VATS provided the benefits of lesser postoperative pain, rapid recovery, short hospitalization, and smaller scar of wound. Conclusively VATS is a new interesting modality of surgical treatment of spontaneous pneumothorax and also can be extensively applicable in the diagnosis and treatment of other intrathoracic disease.

10.Air leakage due to the cuff hanging on the vocal cords during nasotracheal intubation: a case report

Nasotracheal intubation is commonly performed under general anesthesia in oral and maxillofacial surgery. For the convenience of surgery, nasal Ring-Adair-Elwyn (RAE) tubes are mainly used. Because the nasal RAE tubes were bent in an “L” shape, the insertion depth was limited. Particularly, it is necessary to accurately determine the appropriate depth of the RAE tubes in children. Several types of nasal RAE tubes are used in the medical market, which vary in material and length. We performed endotracheal intubation using a nasal RAE tube for double-jaw surgery, but air leakage persisted even when the air pressure in the cuff was increased. When checked with a laryngoscope, it was confirmed that the tube was pushed out, and the cuff was caught on the vocal cords, causing air leakage. Since inserting the tube deeply did not solve the problem, replacing it with a nasal RAE tube (Polar TM , Preformed Tracheal Tube, Smith Medical, Inc., USA) did not cause air leakage; thus, we reported this case.
