The purposes of this work were to assess the cognition of the registered nurse(RN) on oral and maxillofacial emergency treatment and to compare cognition of the RN with that of the 119 emergency medical technician(EMT). 450 RNs who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. Independent sample t-test and chi-square test were used to assess the state of RN on dental emergency treatment and to compare RN with EMT. The question 'education time on dentistry in formal education' that marked '0 hour' and '1-3 hours' were 73.3% and 20.0%, respectively. The question 'refresher training class on dentistry' that marked '0 hour' and '1-3 hours' were 92.9% and 6.7%, aggregately 99.6%. The results showed low score in the question 'reduction of temporo-mandibular joint(TMJ)'($1.67{\pm}0.857$), 'fixation of dislocated TMJ'($1.70{\pm}0.853$) and 'post-avulsed tooth treatment'($1.78{\pm}0.774$) by 5-point Likert scale. Likewise, the scores were $2.02{\pm}0.806$ in the question 'treatment of maxillofacial trauma', $2.76{\pm}1.061$ in the question 'emergent care of avulsed tooth', $2.70{\pm}1.095$ in the question 'treatment time of avulsed tooth' and $2.79{\pm}1.056$ in the question 'mouth guard', respectively. Compared to EMT, results of RN showed a statistically lower figure(p<0.05) in all items compared except the question 'medicine control', and the question 'doctor care in emergency room' was borderline(p=0.069). From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial emergency treatment for the initial management of injuries. Authors suggest further co-study and nation-wide research with nursing care.

This case report is a treatment of patient with hemophilia A and autism. The patient's chief complaint was treatment of dental caries on entire dentition and he has an impacted mesiodens located on the apex of the upper right primary central incisor. The patient was consulted with pediatrician and anesthetist about the detailed discussion of the complexities of hemorrhagic disorder. Because he had some problems of behavior management and bleeding, the treatment was done under the gerneral anesthesia. The following results were obtained. 1. Consult with the patient's physician and hematologist about the replacement therapy and bleeding tendency. 2. For the severe hemophiliac child who requires extensive or surgical treatment, general anesthesia may be indicated for the comprehensive care. 3. For the hemophiliac child who has a behavior management problem due to autism and other defects, general anesthesia may be considerable. 4. Care must be taken during dental procedures not to causing a bleeding. 5. Local hemostatic methods must be acquired for the emergency state. 6. Neve prescribe aspirin or non-steroidal anti-inflammatory drugs such as ibuprofen, indomethacin, and phenylbutazone. These drugs affect platelet aggregation and exaggerate the bleeding defect. 7. Do not be afraid of hemophiliac patient, and never compromise quality of dental care.

The purpose of this study is to investigate the types of domestic safety accidents involving children and to verify the difference of safety knowledge according to variables of parents. Subjects include 226 parents who have 3-5 year old infants enrolled in kindergartens and day care centers in I-city, Jeollabuk-do. The study tools are modified and complemented questionnaire for the study purpose referred to the preceding research data and the literature. For the processing of collected data, frequency analysis, descriptive statistics, one-way ANOVA, and the Duncan post-test were utilized using the SPSS program. The results of this study are as follows: First, safety accidents occurred at the majority of homes which have infant children. On average, the occurrence frequency was 1.78 times per six months. The accidents involving infants occurred in the order of drop or slip, crash or impact, stricture or jamming, fall, stab or cut, burn, swallow or inhalation. Second, both parents had an average level of safety knowledge. There was a distinction in the areas of 'fall' and 'first aid' according the mother's age. In addition, stay-at-home mothers had the higher level of safety knowledge compared with working mothers in the areas of 'general safety knowledge' and 'fire'. There was a distinction in the area of 'fire' according to the father's age. Given these findings, safety training programs for parents to improve safety knowledge needs to be developed.

The expectoration of blood is always a fearful experience for the patient and a matter of grave concern to the attending physician, because it may be the warning sign of serious diseases. When such bleeding occurs, the possibility of its being due to pulmonary tuberculosis, bronchiectasis or carcinoma of the lung is promptly suggested. Nowadays, with the advance of modern diagnostic studies, differential diagnosis has become possible for the hemoptysis patients to have appropriate treatment. This evaluation is based on the review of 75 cases of patients whom we performed emergency open thoracotomies for 6 years from March 1992 to February 1997 in the Department of Thoracic and Cardiovascular Surgery, Seoul Adventist Hospital. The mean age of the patients was 36.6 years old with a range from 19 to 68, and most prevalent age group was thirties. The most common underlying lung disease causin hemoptysis was tuberculosis(44%). Most accurate diagnostic study was bronchoscopy during hemoptysis(95 Vo) and right middle & lower lobe(17.3%) was the most common site of lesion. Lobectomy(50%) was the most frequent operative method and recurrent hemoptysis(31.6%) was the most common postoperative complication. But most of the patients(82.6%) were completely recovered by surgical treatment. Now we concluded that the proper management of hemoptysis was completed by surgical approach with definite diagnosis and supportive medication.

Purpose: The purpose of this study is to compare the clinical features and complications of snake bite patients in urban and rural areas. Methods: A retrospective study was conducted on patients over 18 years of age who were hospitalized for snake bites from January 2013 to December 2019. Patients were categorized into urban and rural groups according to their respective locations at the time of the snake bite and the clinical characteristics and complications of the two patient groups were researched and compared. Results: Of the 77 snake bite patients, 44 patients were categorized into the rural group (57.1%). The rura1 group showed significant differences in old age (p=0.011), delayed hospital visits (p=0.010), far hospital distance (p<0.001), high local effect score (p<0.001), high traditional snake-bite severity grading scale (p=0.008) and use of large amounts of antivenins (p=0.026). There was a significantly higher incidence of acute kidney injury (p=0.030), rhabdomyolysis (p=0.026), and coagulopathy (p=0.033) in the rural group as well as a longer hospitalization period (p<0.011). Conclusion: Snake bites that occurred in rural areas resulted in patients with more complications compared to urban areas due to farther distances from hospitals, causing a delay in antivenom treatment.

The purpose of this study were to evaluate the effect on the reversion of sedation induced by midazolam with flumazenil and to determine the plasma concentration of flumazenil according to the method of administration. Intranasal and intravenous flumazenil were administered to sedated health volunteers aged from 23 to 25 years, in doses typical of those used clinically to induce sedation with midazolam and for reversal with flumazenil. Objective assessment for degree of sedation and vital signs, plasma concentration were made for 2 hours period. 1. Systolic and diastolic blood pressure, $SpO_2$ were not changed by adminstration of flumazenil in sedated subject with midazolam, but pulse rate was increased temporarily. 2. Flumazenil showed the reversal of the sedative effect induced by midazolam regardless of administration methods. But intravenous administration showed more effect on the degree and the duration of reversion than intranasal administration with the exception of on set time. 3. Peak plasma concentration of flumazenil administered by intranasal route reached after 2 min and that of flumazenil administered by intravenous route was 4 min. Thus uptake of flumazenil did not showed any difference in accordance with the adminstration route. 4. Administration of flumazenil resulted in the temporary increase of midazolam plasma concentration.

This paper describes an EEG(electroencephalogram) software for two-channel cerebral function monitoring system to detect the cerebral ischemia. In the software, two-channel bipolar analog EEG signals are digitized and from the signals various EEG parameters are extracted and displayed on a monitor in real-time. Digitized EEG signal is transformed by FFT(Fast Fourier transform) and represented as CSA(compressed spectral array) and DSA(density spectral array). Additional 5 parameters, such as alpha ratio, percent delta, spectral edge frequency, total power, and difference in total power, are estimated using the FFT spectra. All of these are effectively merged in a monitor and displayed in real-time. Through animal experiments and clinical trials on men, the software is modified and enhanced. Since the software provides raw EEG, CSA, DSA, simultaneously with additional 5 parameters in a monitor, it is possible to observe patients multilaterally. For easy comparison of patient's status, reference patterns of CSA, DSA can be captured and displayed on top of the monitor. And user can mark events of surgical operation and patient's conditions on the software, this allow him jump to the points of events directly, when reviewing the recorded EEG file afterwards. Other functions, such as forward/backward jump, gain control, file management are equipped and these are operated by simple mouse click. Clinical tests in a university hospital show that the software responds accurately according to the conditions of patients and medical doctors can use the software easily.
