A retrospective study has been made of 784 cases of road traffic casualties who were treated at the Soon-Chun-Hyang Hospital between July 1980 and December 1981. This study was conducted to find out the nature and pattern of the traffic accident from the clinical and epidemiological standpoints. In additions, the mode of injury from the road accidents were persued which might help to reduce the misdiagnosis rate. The results obtained were as follows: l. In this survey, male dominated in numbers (casualty rate, 70%). The highest incidence was in the age group between 31–40 year (26.5%). The predominance was found in younger casualties (ages between 21–50 years, 72.1% of all casualties). 2. The large number of casualties followed the rush hours. There was a peak between 10PM to midnight. The explanation for this high incidence during the hours was the hurry-up life due to midnight crufew, pedestrian's carelessness and hurry-scurry, and the negligence of traffic rules, the poor labor conditions and weariness due to drivers long continuous working hours, especially in taxi drivers. The highest seasonal incidence was in October. 3. The high incidences were in drivers and students; the drivers were the commonest victims in car passenger accidents and students were injured by pedestrians accidents respectively. The causes of high risk of injury in drivers were intimately related with their vocational aptitudes, the employment status, the driving attitudes and car maintainances; and in students, their carelessness and emotional instability, unsolved mass transportation system and their negligence of traffic rules were listed as the causative factors. 4. Over 51.8% of all casualties were injured by passenger car accidents, and 21.5% were by truck and other types of special vehicles. 5. Approximately 60% of victims were injuried in the road as pedestrian and other 40% were in the car as passengers. In general, the pedestrian injuries were more serious than those sustained in the car as passengers. 6. About 40% of total pedestrian casualties sustained injury at pedestrian's cross road. 7. About 80%of injured drivers were in the drunken state on arrival, and 20.4% of pedestrians were also heavily drunken. 8. The trauma risk was about twice higher in the front-seated passengers than the rear-seated ones in the car. In buses, the highest incidence was in the passengers seated in the front 1/3 of the seats. 9. Orthopaedic (40.5%) and head injuries (38.2%) were the commonest types of the injuries among the hospitalized casualties; about 35% of total patients had the tibial fractures. 10. Of the 784 cases, 479(61.6%) victims arrived hospital within 30 minutes after accident, and among them only 94 cases (12%) were transported by ambulance from the accident site to the hospital.

Although the endotracheal intubation using laryngoscope can usually be performed under general anesthesia, it may be very difficult in situations such as head and neck trauma, hemorrage, or deformity. Recently we performed antegrade fiberoptic nasotracheal intubation with a guide wire. A 15-month aged female child with mandibular fracture was scheduled for open reduction and internal fixation under general anesthesia. She was anticipated difficult intubation due to displacement of the fracture site. After induction of anesthesia, we passed an adult fiberoptic bronchoscope (O.D. 3.8 mm, LF-2, Olympus optical co, Japan) to vocal cord via right nostril. Then a guidewire was inserted through the suction port of bronchoscope, and bronchoscope was removed in a state of guidewire in situ. We slid the endotracheal tube over guidewire according to Seldinger's technique. We think that nasotracheal intubation using an adult fiberoptic bronchoscope and a guidewire is good for children under 2 years old who are expected the difficult intubation.

BACKGROUND: Bupivacaine induces cardiac depression, which is resistant to treatment. Therefore early recognition of its development is important so that the injection of bupivacaine can be discontinued promptly. We compared the efficacy of continuous mixed venous oxygen saturation (cSvO2) monitoring with that of the mean arterial blood pressure (MBP) monitoring in terms of the prediction of cardiac output (CO) changes in anesthetized dogs with bupivacaine-induced cardiovascular depression. METHODS: Bupivacaine was infused to pentobarbital-anesthetized mongrel dogs (n = 8) at a rate of 0.5 mg/kg/min until the MBP decreased to 40 mmHg or less (end of bupivacaine infusion; BIE). We defined the early period as the interval from baseline till 30 minutes after the bupivacaine infusion and the late period as that after the 30 minutes till BIE. We monitored cSvO2 with a fiberoptic pulmonary artery catheter. The MBP and CO were measured every ten minutes after the initiation of the bupivacaine infusion. Arterial blood gas analysis, mixed venous gas analysis, measurement of serum electrolyte concentrations and serum bupivacaine concentrations were performed simultaneously. The relationship between CO versus cSvO2 or versus MBP was compared retrospectively by regression analysis. RESULTS: The Pearson's correlation coefficients between CO and cSvO2 were 0.782 (r2 = 0.6111, P < 0.01) in the early period and 0.824 (r2 = 0.6790, P < 0.01) in the late period. The correlation coefficients between CO and MBP were 0.019 (r2 = 0.0003, P > 0.05) in the early period and 0.799 (r2 = 0.6381, P < 0.01) in the late period. CONCLUSIONS: cSvO2 is superior to MBP for the prediction of CO changes in bupivacaine-induced cardiac depression in dogs, especially in the early period. We might expect a profound reduction of CO when MBP begins to decrease in the late period.

An interlocking intramedullary nail is the most popular device for managing tibial shaft fractures. Interlocking screws should be inserted to prevent rotation at the fracture site, but inserting distal interlocking screws by free hand technique requires time and skill. The BrookerWills tibial nail was designed to stretch out distal metal fins after settling the nail in position. On the other hand, Brooker-Wills nails should be removed for reasons such as chronic osteomyelitis, and folding the distal metal fins is necessary. Nevertheless, many problems arise in this process. Usually, the removal of Brooker-Wills tibial nails is not attempted because of this trouble. The authors tried a new method and could fold the fins successfully in a 30-year-old Brooker-Wills tibial nail, which had to be removed to cure a chronic osteomyelitis around the nail. This paper reports the case of a 72-year-old male with a review of the relevant literature to suggest a useful method.

PURPOSE: To identify the brain centers associated with visually evoked sexual arousal in the human brain, and to investigate the neural mechanism for sexual arousal using functional MRI (fMRI). MATERIALS AND METHODS: A total of 20 sexually potent volunteers consisting of 10 males (mean age: 24) and 10 females (mean age: 23) underwent fMRI on a 1.5 T MR scanner (GE Signa Horizon). The fMRI data were obtained from 7 slices (10 mm slice thickness) parallel to the AC-PC (anterior commissure and posterior commissure) line, giving a total of 511 MR images. The sexual stimulation consisted of a 1-minute rest with black screen, followed by a 4-minute stimulation by an erotic video film, and concluded with a 2-minute rest. The brain activation maps and their quantification were analyzed by the statistical parametric mapping (SPM 99) program. RESULTS: The brain activation regions associated with visual sexual arousal in the limbic system are the posterior cingulate gyrus, parahippocampal gyrus, hypothalamus, medial cingulate gyrus, thalamus, amygdala, anterior cingulate gyrus, insula, hippocampus, caudate nucleus, globus pallidus and putamen. Especially, the parahippocampal gyrus, cingulate gyrus, thalamus and hypothalamus were highly activated in comparison with other areas. The overall activities of the limbic lobe, diencephalon, and basal ganglia were 11.8%, 10.5%, and 3.4%, respectively. In the correlation test between brain activity and sexual arousal, the hypothalamus and thalamus showed positive correlation, but the other brain areas showed no correlation. CONCLUSION: The fMRI is useful to quantitatively evaluate the cerebral activation associated with visually evoked, sexual arousal in the human brain. This result may be helpful by providing clinically valuable information on sexual disorder in humans as well as by increasing the understanding of the neuroanatomical correlates of sexual arousal.

Ticlopidine hydrochloride is world-wide used antiplatelet agent that inhibit ADP pathway. Its clinical side effects are the change of the blood picture, allergic skin reaction and gastrointestinal symptoms. We report three patients with severe cholestatic hepatitis caused by ticlopidine. They developed jaundice about 20days after taking ticlopidine (500 mg/day). Infectious and immunological etiologies were excluded by serology. There was no history of alcohol or drug abuse. Their symptoms were gradually subsided for a few months after discontinuing ticlopidine.

BACKGROUND: There have been a lot of methods that prevent catatrophic airway fires during laser surgery, but none of them can protect endotracheal tube cuff exposed directly to laser beam. This study was performed to know the preventive effect of viscous lidocaine-filled cuffs on laser-induced combustion, and to know how long we can maintain positive pressure ventilation if laser beam broke out cuff perforation. METHODS: Transparent acrylic trachea attached to artificaial lung was intubated with 8.0 ID polyvinylchloride endotracheal tube. Cuff was filled with 8ml of saline or saline and viscous lidocaine mixture with 2:1 or 4:1 ratio. Positive pressure ventilation with air in tidal volume of 500 ml was begun. The laser output was set to 10 watt/sec in the continuous mode with beam diameter of 1 mm. Laser beam was directed perpendicularly at the part of the cuff protruding between endotracheal tube shaft and acrylic trachea, and laser emission was continued until the cuff was perforated or combusted. RESULTS: There was no case of laser-induced fires. After the perforation of cuff, the tidal volume was slowly decreased in 2:1 mixture of saline and viscous lidocaine filled cuff compared to others (P<0.05). CONCLUSION: 2:1 mixture of saline and viscous lidocaine may be used as an efficient inflating material of endotracheal tube cuffs on laser airway surgery.

The incidence of anaphylaxis to intravenous agents used for general anaesthesia is reported as about 1 : 6000. Despite appropriate treatment, mortality is reported as about 6%, thus it is important to try to minimize the risk by prevention. A adequate investigation, communication and avoidance of drugs responsible with the use of pretreatment and alternative techniques, the risk of second reaction should be reduced. A patient who has the history of anaphylactic shock to thiopental, for the induction of anesthesia was scheduled for subtotal gastrectomy. Skin test confirmed that she had a hypersensitivity to a thiopental. We performed combined general and spinal anesthesia. She was premedicated with dexamethasone and pheniramine malate in the operating room. Spinal blockade is up to T6 by 0.5% tetracaine. Then, anesthesia was induced with propofol and midazolam. There is no need for muscle relaxant drugs and anesthesia was maintained with isoflurane, N2O, O2. Subtotal gastrectomy was done without event. Combined general and spinal anesthesia affords the anesthesiologist the opportunity to lower the local anesthetic doses, to avoid using many kinds of intravenous drugs (muscle relaxants, opioids, benzodiazepine, etc.) and to approach a kind of anesthesia that is close to the ideal anesthesia.

Background: Although an ambulatory surgical practice continues to increase, there is a few data exist about patient discharge criteria. This study was undertaken to evaluate the usefulness and safety of Aldrete PAR (postanesthetic recovery) score and modified PADSS (modified postaneathesia discharge scoring system) on ambulatory surgery patients for recovery in Korea. Methods: Demographic, anesthetic data, Aldrete PAR score and modified PADSS on 279 patients were recorded. The time to dicharge, from recovery room and postoperative complications were evaluated, also. Results: PAR score and modified PADSS are correlated to length of stay in ambulatory surgery center. 24hr after discharge, 16% patients complained postoperative complications. Pain was most frequent postoperative complication. The PAR score was correlated with the occurrence of the complication. Conclusion: PAR score and modified PADSS are useful scoring systems to evaluate patients and make a decision to discharge the patients from ambulatory surgery center in safe.

PURPOSE: The purpose of the study was to develop and evaluate the effect of a metabolic syndrome prevention program using mobile application for university students. METHODS: A pretest-posttest design with content analysis as a triangulation method was used. The participants were 49 university students. Data were analyzed using descriptive statistics, chi2-test, t-test and Fisher's exact test with the SPSS WIN 18.0 program. RESULTS: The application consisted of six main menus as follows: 'basic education', 'nutrition education', 'exercise education', 'meal diary', 'exercise checkup', and 'tips'. The experimental group had higher recognition about metabolic syndrome prevention than the control group (F=7.919, p=.007). Understanding of metabolic syndrome among participants was mostly related to chronic diseases such as obesity, hypertension and diabetes in relation to the importance of eating habits and exercising. CONCLUSION: The results indicate that metabolic syndrome prevention education using mobile application is necessary and would be useful for university students.
