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.

Background: Pleural abnormality is the the most common respiratory change caused by asbestos dust inhalation and also develop other asbestos related disease after cessation of asbestos exposure. So we conducted epidemiologic study to investigate if the pleural abnormality is associated with pulmonary function change and what factors are influenced on pulmonary function impairment. Methods: Two hundred and twenty two asbestos workers from 9 industries using asbestos in Korea were selected to measure the concentration of sectional asbestos fiber. Ouestionnaire, chest X-ray, PFT were also performed. All the data were analyzed by student t-test and chi-square test using SAS. Regressional analysis was performed to evaluate important factors, for example smoking, exposure concentration, period and the existence of pleural thickening, affecting to the change of pulmonary function. Results: 1) All nine industries except two, airborn asbestos fiber concentration was less than an average permissible concentration. PFT was performed on 222 workers and the percentage of male was 88.3%, their mean age was $41{\pm}9$ years old, and the duration of asbestos exposure was $10.6{\pm}7.8$ yrs. 2) The chest X-ray showed normal(89.19%), pulmonary Tb(inactive)(2.7%), pleral thickening (7.66%), suspected reticulonodular shadow(0.9%). 3) The mean values of height, smoking status, concentration of asbestos fiberwere not different between the subjects with pleural thickening and others, but age, cumulative pack-years, the duration of asbestos exposure were higher in subjects with pleural thickening. 4) All the PFT indices were lower in the subjects with pleural thickening than in the subjects without pleural thickening. 5) Simple regression analysis showed there was a significant correlation between $FEF_{75}$ which is sensitive in small airway obstruction and cumulative smoking pack-years, the duration of asbestos exposure and the concentration of asbestos fiber. 6) Multiple regression analysis showed all the pulmonary function indices were decreased as the increase of cumulative smoking pack-years and especially in the indices those are sensitive in small airway obstruction. Pleural thickening was associated with reduction in FVC, $FEV_1$, PEFR and $FEF_{25}$. Conclusion: The more concentration of asbestos fiber and the more duration of asbestos exposure, the greater reduction in $FEF_{50}$, $FEF_{75}$. Therefore PFT was important in the evaluation of early detection for small airway obstruction. Furthermore pleural thickening without asbesto-related parenchymal lung disease is associated with reduction in pulmonary function.

Background: For the diagnosis or evaluation of airway obstruction in bronchial asthma and chronic obstructive lung disorders, various parameters derived from the forced expiratory volume curve and maximal expiratory flow volume curve have been used. Recently the peak expiratory flow(PEF) measured by the peak flow meter is widely used because of its simplicity and convenience. But there were still no data of the predicted normal values measured by the peak flow meter in Korea. This study was to obtain the predicted normal value of PEF and to know the accuracy of this value to predict $FEV_1$. Method: The measurements of PEF by the MiniWright peak flow meter and several parameters derived from the forced expiratory volume and maximal expiratory flow volume curves by the Microspiro HI 501(Chest Co.) were done in 129 men and 125 women without previous history of the respiratory diseases. The predicted normal values of parameters according to the age and the height were obtained, and the regression equation of $FEV_1$ by PEF was calculated. Results: The predicted normal values of PEF(L/min) were -2.45$\times$Age(year) +1.36 $\times$ Height(cm)+427 in men, and -0.96 $\times$ Age (year) + 2.01 $\times$ Height (cm) + 129 in women. FEFmax derived from the maximal expiratory flow volume curve was less than by 125 L/min in men and 118 L/min in women respectively compared to PEF. $FEV_1$(ml) predicted by PEF was 5.98 $\times$ PEF(L/min) + 303 in men, and 4.61 $\times$ PEF(L/min) + 291 in women respectively. Conclusion : The predicted normal value of PEF measured by the peak flow meter was calculated and it could be used as a standard value of PEF while taking care of patients with airway obstruction. $FEV_1$, the gold standard of ventilatory function, could be predicted by PEF to a certain extent.
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 term tracheal bronchus refers to an abnormal bronchus that comes directly off of the lateral wall of the trachea (above the carina) and supplies ventilation to the upper lobe. Tracheal bronchi occur almost exclusively on the right trachea and are associated with other congenital anomalies. In addition, tracheai bronchus may be related to other inflammatory conditions with persistent wheezing, such as recurrent pneumonia, chronic bronchitis and bronchiectasis, which is a result of the relatively poor local drainage of the involved bronchi. An infant with recurrent wheezing is likely to be a challenge for a clinician in the evaluation of the etiology of airway obstruction and in the differential diagnosis of wheezy breathing. The authors report a case of an 8-month-old female infant with a ventricular septal defect, who presented with stridor and recurrent respiratory infection and finally was finally diagnosed with a tracheal bronchus using computed tomography and a bronchoscopy. Therefore, tracheal bronchus should be included in the differential diagnosis of any child who presents with chronic or recurrent respiratory tract symptoms such as coughing, wheezing, stridor and recurrent respiratory infection, particularly in children with other congenital deformities.

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.
