Purpose: Several authors reported about the post - traumatic nasal aesthetic complications. However, the study for functional or intra - nasal complications has been reported not enough. The aim of this study is to observe the incidence of intranasal synechia. Methods: We reviewed the data from 401 consecutive patients with nasal bone fracture from september 2006 to December 2007. We enforced evaluation with preoperative CT in all patients but postoperative CT within complicated patients. We classified the nasal bone fracture according to the anatomy and severity of fracture. Type I is nasal tip fracture(15%, n = 59), Type II is simple lateral without septal injury(38%, n = 152), Type III is simple lateral with septal injury(23%, n = 92), Type IV is closed comminuted(20%, n = 82), Type V is open comminuted or complicated(4%, n = 16). We studied 98 patients with nasal bone fracture who had postoperative symptoms or undergone postoperative endoscopic evaluation. And then we evaluated the postoperative endoscopic finding and nasal synechal formation after operation. Results: The incidence of intranasal synechiae was 15%(n = 62). According to the endoscopic findings, the incidence of intranasal synechiae was 10%(n = 6) in Type I, 8%(n = 12) in Type II, 16%(n = 15) in Type III, 24%(n = 20) in Type IV, and 56%(n = 9) in Type V. Additionally, the incidence of subjective nasal obstruction and olfactory dysfunction is 18%(n = 72) and 13%(n = 51). But the incidence of symptomatic synechiae of nasal obstruction and olfactory dysfunction is 92%(57/62) and 55%(34/62). Conclusion: We identified relatively high prevalence of nasal obstruction and olfactory dysfunction in nasal synechiae. Based on the results of this study, intranasal synechiae really caused airway obstruction(92%). Our data showed significant relationship between intranasal synechiae and severity of the fracture, because of increasing mucosal handling and destructive closed reductional procedures. First of all, education of delicate procedure regarding this subject should be empathized accordingly.

Purpose: With a view to providing basic data to develop cardiopulmonary resuscitation education suitable for elementary students, the cardiopulmonary resuscitation education was conducted to grasp students' knowledge, skills accuracy and the attitude change before and after the education. Methods: Convenience sampling was made on fourth and fifth graders(total-35 students) of S elementary school located in K city, Chungcheongnam-do, and this was a pre-experiment research designed before and after choosing a single group. In terms of methods, specifically we, researchers ; 1) Handed out questionnaires to students directly to make them fill in firsthand and collected the questionnaires. 2) Utilized PPT materials based on 2005 AHA guideline and DVD materials of AHA, to give students theoretical education of cardiopulmonary resuscitation. We used Anne/SkillReporter$^{(R)}$ torso produced by Leardal Inc, and Little Anne to conduct practical education individually. 3) Asked students to give Anne/SkillReporter$^{(R)}$ torso cardiopulmonary resuscitation five times with the ratio of 30 : 2, and then one of researchers filled in the evaluation sheet individually. 4) Evaluated the accuracy of students' ability to perform the resuscitation based on the record of Anne/SkillReporter$^{(R)}$ integrated printer(which was the objective tool to grasp students' skills accuracy). 5) Gave out questionnaires to make students fill them in and then collected them. after completing the practical evaluation. Results: 1) In case of the attitude about cardiopulmonary resuscitation, Students' confidency rose from 19.28%(before the education) to 93.57(after the education)- which is a positive change. 2) As the result of the education, some elementary students scored 11 points (full score-16 points), up from 5 points before the education, in terms of the knowledge about cardiopulmonary resuscitation. The average point also reached 13.14 points(after the education), jump from 8.37(before the education), which was the rise of 29.8%. 3) When it comes to the practical performance, the skills accuracy was 80.93% on average, and the calculation method was as follows: total items were 16, and each item was marked form 0 to 2 points, meaning the full score was 32 points. The minimum score was 19 points and the maximum was 32($M{\pm}SD=25.90{\pm}2.88$), which was calculated based on percentage. 4) Regarding skills accuracy, respiration accuracy(%)($M{\pm}SD=30.20{\pm}27.16$) was higher than pressure accuracy(%) ($M{\pm}SD=15.34{\pm}25.27$). Conclusion: The result showed that students' attitude on cardiopulmonary resuscitation changed positively. and meaningful difference(p = .00) existed in the change of students' knowledge. In terms of skills accuracy. chest compression and airway control showed high accuracy, but the result of Anne/SkillReporter$^{(R)}$ performance showed that the accuracy of chest compression was lower than that of mouth-to-mouth resuscitation.

Background: In previous study, most patients with bronchial anthracofibrosis (BAF) were non-miners, and non-occupational old aged females. However, the clinical significance of BAF in patients with coal workers' pneumoconiosis (CWP) is unknown. Methods: Among patients with CWP who transferred to our hospital for an evaluation of associated pulmonary diseases, 32 patients who had undergone a bronchofibroscopy (BFS) and chest computed tomography (CT) examination were evaluated for the association of the BAF using a retrospective chart review. Results: Nine of the 32 CWP patients (28%) were complicated with BAF. Four of the 16 simple CWP patients (25%) were complicated with BAF. According to the International Labor Organization (ILO) classification by profusion, 2 out of 3 patients in category 1, 1 out of 8 patients in category 2 and 1 out of 3 patients in category 3 were complicated with BAF. Five out of 16 complicated CWP patients were complicated with BAF. Three out of 7 patients in type A and 2 out of 5 patients in type C were complicated with BAF. CWP patients with BAF had significantly greater multiple bronchial thickening and multiple mediastinal or hilar lymph node enlargement than the CWP patients without BAF. There was no difference in the other clinical features between the CWP patients with BAF and those without BAF. Conclusion: Many CWP patients were complicated with BAF. The occurrence of BAF was not associated with the severity of CWP progression. Therefore, a careful evaluation of the airway with a bronchoscopy examination and chest CT is warranted for BAF complicated CWP patients who present with respiratory symptoms and signs, even ILO class category 1 simple CWP patients.

Background and Objectives : In children with tracheal stenosis, operative management remains a challenging problem due to difficulties of operative techniques and postoperative care. The purpose of this study was to determine the effectiveness of tracheal resection with end to end anastomosis as operative management for tracheal stenosis in children. Materials and Methods : 6 children with severe tracheal stenosis underwent tracheal resection with end to end anastomosis. Causes of stenosis were trauma in 1 case and prolonged intubation or tracheotomy in 5 cases. The diagnoses were made by radiologic evaluation (plain X-ray, CT, 3-Dimensional CT) and confirmed by direct laryngoscopy and ventilating bronchoscopy under general anesthesia. Thyroplasty and unilateral arytenoidectomy were performed in 1 case. Suprahyoid release was done in 1 case with severe adhesion. Decanulation was achieved following postoperative endoscopic examination and pulmonary function test. Postoperative physical and radiologic examinations were given at regular intervals. Results : Stenosis were improved from grade III grade I in 4 cases and from grade II to grade I in 2 cases. Decanulation was achieved on average postoperative 6 months in 5 cases, and 10 years in 1 case due to exertional dyspnea. There were 1 each case of immediate postoperative subcutaneous emphysema, pneumothorax and wound infection. Postoperative granulomas at anastomosis site were treated with laser vaporization under suspension laryngoscope and bronchoscope in 3 cases. There was 1 each case of delayed postoperative vocal cord palsy, aspiration pneumonia and loss of cough reflex. Conclusion In tracheal stenosis of children, tracheal resection with end to end anastomosis has good result with preservation of normal airway. Preoperative evaluation of local factors such as swallowing, vocal cord movement and cough reflex and general condition was important for successful treatment. As the cases in adults, authors considered this operation to be a curable operative management for tracheal stenosis.

연구배경: 석면분진의 흡입으로 인한 호흡기 변화중 가장 조기에 그리고 가장 빈번하게 발견되는 것은 늑막 변화이다. 늑막변화에는 늑막상출액, 늑막반, 미만성늑막섬유화로 분류되기도 하나 일반적으로 늑막비후를 단순히 석면폭로의 지표로 여기고 간과하는 경우가 많다. 그러나 석면에 관련된 질환은 대부분이 만성적이고 뒤에 질환이 발현되는 경우가 빈번하여 늑막변화를 나타내는 근로자에 대한 합리적인 관리와 검사가 필요할 것으로 생각된다. 방법: 석면분진을 취급하는 9개 시업장의 작업장 부서별 석면분진농도를 측정하고 석면을 취급하는 업무에 종사하고 있는 222명을 대상으로 하여 설문조사, 흉부 방사선 사진, 폐기능검사를 실시하여 우리나라 석면 취급 근로자들에서 발생되는 늑막변화에 대한 역학조사와 함께 늑막변화에 따른 폐기능의 변화, 그리고 폐기능의 저하에 미치는 인자들에 대한 조사를 실시 하였고 성적은 SAS을 이용하여 분석하였다. 결과: 1) 조사대상 사업장은 총 9개 였으며 대상 사업장중 1개소를 제외하고는 석면분진 농도는 허용농도 이하였다. 조사대상 근로자중 폐기능 검사를 실시한 222명을 대상으로 하였고 남자가 196명(88.3%), 여자 26명(11.7%)였으며 평균 연령은 $41.9{\pm}9.8$세 이었고 평균 석면분진 폭로기간은 $10.6{\pm}7.8$년 이었다. 2) 흉부 방사선 소견상 정상소견을 보인 198명(89.19%), 결핵병변이 관찰된 경우 6명(2.7%), 늑막비후가 보인 경우 17명(7.66%), 망상형 간질성 음영이 의심되는 경우 2명(0.90%)이었다. 3) 늑막비후가 있는 군과 없는 군 사이에 평균신장, 흡연력, 분진농도에는 차이가 없으나, 늑막비후가 없는 군에 비하여 있는군에서 연령, 흡연자의 누적 흡연력, 분진 폭로기간이 유의하게 증가되어 있었다. 4) 늑막비후가 있는 군과 없는 군에서 폐기능의 차이를 보면, 모든 폐기능의 지표에서 늑막비후가 있는 군에서 늑막비후가 없는 군에 비해 유의한 감소를 보였다. 5) 단순회귀분석에서 누적흡연력이 클수록, 폭로기간이 길수록, 그리고 분진농도가 높을 수록 폐기능지표들은 감소하였으며 특히 소기도폐색의 지표인 $FEF_{75}$에서 유의하게 변화하였고 누적흡연력은 $FEF_{50}$의 변화에 유의한 영향을 미쳤다. 6) 다중회귀분석시 폐기능지표등이 누적흡연력이 증가할수록 감소하는 경향을 보였으나 주로 소기도폐색지표에 유의한 감소를 보였으며, 늑막비후가 있는 군에서 없는 군에 비하여 폐기능이 현저히 감소하였다. 결론: 석면 취급 근로자에서 여러가지 폐기능 검사 항목과 석면분진농도등 영향을 미칠수 있는 인자를 조사한 결과 분진폭로농도와 폭로기간에 따라 $FEF_{50}$와 $FEF_{75}$이 특히 민감하게 반응하여 석면에 대한 폐질환의 조기진단을 위하여 도움이 될 것으로 생각되며, 본 연구에서 폐실질병변은 없으나 늑막비후만 관찰되는 경우에도 폐기능이 현저하게 감소한 것으로 미루어 이에 대한 적극적인 관리가 필요하다.

연구배경: 기관지 천식 환자들과 만성폐쇄성폐질환의 진단이나 기도폐쇄 정도를 알기 위하여 통상적으로 노력성 호기곡선이나 최대호기류량곡선을 이용한 환기기능검사가 널리 이용되고 있다. 그러나 외래를 방문하는 환자들이나 자가 치료를 하는 환자들의 경과관찰에는 검사의 간편성으로 인해 peak flow meter를 이용한 peak expiratory flow(PEF)가 많이 이용된다. 이 경우 PEF의 변이성이 크기 때문에 절대값이나 증상이 없을 때의 최대값을 기준으로 비교하여 사용하기도 하는데 검사 판정의 객관성은 추정정상치가 가장 높을 것이다. 그러나 현재까지 국내에서는 최대호기류량곡선을 이용한 PEF(FEFmax)의 추정정상치의 보고는 다수 있으나 peak flow meter를 이용한 보고는 아직까지 없었다. 이에 실제 환자들이 스스로 쉽게 측정할 수 있는 PEF의 추정정상치를 산출하고 이 값이 $FEV_1$을 비롯한 다른 환기기능검사를 어느 정도 정확하게 예측할 수 있는 지를 조사 연구하였다. 방 법: 호흡기 증상이나 기왕 병력이 없는 건강한 남자 129명(나이 ; 19-74 세), 여자 125명(나이 ; 18-67세)을 대상으로 외래에서 mini-Wright peak flow meter(Clement Clarke International Ltd. England)를 이용하여 3 회 이상 PEF를 측정하였다. 아울러 Microspiro HI-501 portable spirometer(Chest Co., Japan)로 노력성호기곡선, 최대호기류량곡선을 측정 분석하여 $FEV_1$, FVC, $FEV_1/FVC$, $FEF_{25-75%}$, $FEF_{25%}$, $FEF_{50%}$, $FEF_{75%}$와 FEFmax를 구하여 각각의 추정정상치를 구하였고 PEF의 $FEV_1$ 및 FEFmax에 대한 설명력을 회귀분석을 통해 구하였다. 결 과: PEF(L/min)의 추정정상치는 남자가 -2.45$\times$Age(year) + 1.36 $\times$ Height(cm) + 427였고 ($R^2=0.28$), 여자에서는 -0.96 $\times$ Age(year) + 2.01 $\times$ Height(cm)+129였다($R^2=0.12$). 최대호기류량곡선에서 산출한 FEFmax는 PEF보다 납자에서는 $125{\pm}74.0$(L/min), 여자에서는 $118{\pm}52.2$(L/min) 적었다. PEF로 예측할 수 있는 $FEV_1$(ml)값은 남자에서 5.98 $\times$ PEF(L/min) + 303 이고 ($R^2=0.43$), 여자에서는 4.61 $\times$ PEF(L/min) +291 이었다($R^2=0.33$). 결 론: 건강한 성인 254명(남자 129명, 여자 125명)을 대상으로 peak flow meter로 측정한 PEF의 추정정상치를 연령과 신장을 변수로 하여 구하였다. 여기서 측정한 PEF로 $FEV_1$ 및 FEFmax를 어느 정도 예측할 수 있었다. 그리고 측정기계 및 방법에 따라서 PEF 값이 달라짐을 확인하였는데 이런 점을 유의한다면 PEF의 측정은 향후 환자 진료에 많은 도움이 될 것으로 생각한다.

The purpose of this Study was to examine the efficacy and compliance of a mandibular advancement device(MAD) according to the severity of sleep apnea in the snorers and obstructive sleep apnea patients. Fifty-four patients (45 males, 9 females, aged 20 - 68years ) who visited Seoul National Uiversity Dental Hospital(SNUDH) to seek for the treatment of snoring and sleep apnea were classified into four groups according to the results of the nocturnal polysomnography and they were instructed to wear MAD regularly which was designed to increase the size of the upper airway by advancing the mandible. The evaluation of the efficacy and compliance of the MAD according to the severity of apnea and the duration after the usage of MAD ( 1week, 1month, 3months, 6months, 12months) was made by using quesionnaires mad in Department of Oral Medicine and Oral diagnosis, SNUDH. The obtained results were as follows : 1. All subjects results were habitual snoreres and 43 patients(79.6%) complained the loudness of snoring that can be heard out of the room. 2. Apnea index(AI) of the total subjects was mean 29.4$\pm$26.9 and respiratory disturbance index(RDI)was mean 37.6$\pm$28.0. And there was nodifference in the efficacy and the compliances of MAD according to the severity of apnea. 3. The severityi of apnea by the questionnaires significantly corresponded with the results of nocturnal polysomnography, and this fact potentiated the diagnostic value of the questionnaire. 4. after the usage of MAD, there was significant improvement in the frequency of snoring, the loudness of snoring, frequency of apnea, daytime sleepiness nad the refreshment after sleep(p<0.001) regardless of the apnea index(AI) and respiratory distrubance index(RDI). 5. The degree of the satisfaction with MAD was mean 74.4$\pm$18.4% and that of the discomfort with the MAD was 31.4$\pm$19.6%. But there was no serious complication in occlusion and temporomandibular joint with the usage of MAD and the duration of the discomfort was mean 3.3$\pm$2.2 weeks. 6. Forty-one patients(75.9%) continued the usage of MAD but thirteen patients(24.1%) stopped the use of MAD because of the discomforts and insufficient results with it.

The Fontan operation is a heart operation used to treat complex congenital heart defects like tricuspid atresia, hypoplastic left heart syndrome, pulmonary atresia and single ventricle. A single ventricle is dedicated to pumping oxygenated blood to the systemic circulation and the entire systemic venous return reaches the pulmonary arterial system without the direct influence of a pumping chamber. In the patient with Fontan operation, it is important to achieve adequate pulmonary blood flow and cardiac output in anesthetic management. In this case, a 10-year-old boy (19.6 kg, 114 cm) with cleft palate, cerebral palsy and severe mental retardation, who underwent a Fontan operation when he was 4 years old, was presented for deep sedation. Because he was suffering from eating disorder with cleft palate, the orthodontist and the plastic surgeon planned to insert intraoral orthodontic device before cleft palate repair. But it was impossible to open his mouth for alginate impression procedure. After careful pre-anesthesia evaluation we planned to administer deep sedation with propofol infusion. After Intravenous catheter insertion, we started propofol intravenous infusion with the formula of a loading dose of 1.0 mg/kg followed by an infusion rate of 6.0 mg/kg/hr with syringe pump. His blood pressure was remained around 80/40 mmHg after loss of consciousness, but he could not maintain his airway patent. So we lowered the infusion rate to 3.0 mg/kg/hr, immediately. The oxygen saturation was maintained above 95% with nasal oxygen supply, and blood pressure was maintained around 100-80/60-40 mmHg. After the sedation of 110 minutes with propofol (the infusion rate to 3.0-5.0 mg/kg/hr), he fully regained consciousness, and was discharged without complication after 1 hour observation. In case of post-Fontan patient, intravenous deep sedation with propofol was safe and effective method of behavioral management during dental treatment.

The main purpose of this study is to examine the concepts appeared on research and provide future research directions in field of child health nursing. 205 studies of the total 318 studies had been analyzed first for the concepts of the client domain and this time 113 studies were analyzed for the practice, the client-nurse and the environmental domain in nursing. The practice domain includes mentalistitic, enactment, knowledge utilization, role related phenomenon, the client-nurse domain includes touch, communication, interaction phenomenon, and the environmental domain includes physical, social, symbolic environment. All were originally published between 1990 and 2000 in Korea. An analysis of concepts for this study was used the metaparadigm framework for nursing proposed by H. S. Kim(2000). 1. 103 studies belonged to the practice domain. Among them, 56(54％) studies used concepts related to enactment phenomenon like education(21.4％), giving information(7.1％), breast feeding(5.4％), caring(5.4％), airway suction(5.4％), nonnutritive sucking(5.4％). 44(43％) studies used concepts related to knowledge utilization like program development and evaluation of smoking, mother-infant interaction, home health nursing, obesity management. And only 3(3％) studies used role related concepts like quality of nursing, direction of health education, contents of child health nursing education. 2. Only 2(0.006％) studies belonged to the client-nurse domain. One concept is empathy in communication phenomenon and the other concept is role conflict in interaction phenomenon. 3. 8(0.02％) studies belonged to the environmental domain. Among them, 3 studies related to physical environment like space, noise and 5 studies related to social environment like social support, home environment. But the concept of symbolic environment was not used. The findings of this study provide the evidence that research related to the client-nurse domain and the environmental domain should be conducted actively to improve the practice of child health nursing. So that the research in field of child health nursing should be dealt with the concepts of four domains to develop knowledge systematically.
