신생아 호흡 장애 증후군에서 폐외공기누출의 임상적 고찰

우석정 대한흉부심장혈관외과학회 1999 Journal of Chest Surgery (J Chest Surg) Vol.32 No.1

1994년 9월에서 1997년 5월까지 신생아 호흡곤란을 보였던 환아들중 폐외 공기 누출을 나타내었던 48례를 대상으로 그 임상 양상을 분석하였는데 일차성 15례, 이차성 33례를 보였고, 순수 폐간질 기종이 19례, 다른 병변과 동반된 기흉이 19례 있었다. 정상 체중아가 많고 24시간내 증상 발현의 경우가 많았다. 폐 질환으로는 유리질 막증, 태변 흡입 증후군, 폐렴 등이 있었다. 25.2%의 원내 사망율을 보였고 유리질막증 환자에서 많았다. Background: In neonatal respiratory distress syndrome patients, various types of pulmonary air leak contributes to elevate morbity and mortality. Although early surgical interventions can provide better results in several cases, whole clinical outcomes are poor. This study was designed to investigate the clinical aspects of pulmonary air leak in the neonatal respiratory distress syndrome patients and major contributing factors to mortality. Material and Method : We retrospectively evaluated 48 cases of pulmonary air leak in the neonatal respiratory distress syndrome patients from September 1994 to May 1997. Result: There were 15 cases of primary and 33 cases of secondary pulmonary air leakages. The prominent manifestations were pure interstitial emphysema in 19 cases(39.9%) and combined pneumothorax in 19 cases(39.9%). In clinical aspects, normal birth weight was dominant(83.4%), the onset occurred within 24 hours was in 28 cases(58.8%). The pulmonary diseases were meconium aspiration syndrome(25.2%) and hyaline membrane disease(33.2%). The overall hospital mortality was 25.2%, and the majority were hyaline membrane diseases. Conclusion: Although the overral mortality rate of these diseases were high, more detailed studies about immediate treatement, perinatal prevention, intensive care to geriatric problems were needed individually to improve outcomes.

From March 1988 to May 1991, 140 CarboMedics cardiac valve prostheses[75 mitral, 9 aortic and 28 double aortic-mitral] were implanted in 112 consecutive patients[mean age 36.7$\pm$11.6 years, male/female 48/76] by one surgical team operating on adult cardiac patients at Kyoungpook University Hospital Associated Surgical procedures were performed in 19 patients[16.9%]. Total follow up represented 2,345 patient-months[mean 22.4 months] and was 100% complete. Eighty-two patients[73%] were in NYHA functional class IIIor IV preoperatively and 102 patients [95%] were in class I or II postoperatively. Hospital[30 day] mortality was 4.4%, [3/75 mitral, 1/9 aortic, 1/28 double valve replacement] and late death was 1.7%. [1 /74 mitral, 1 /28 double valve replacement] The actuarial survival at 36 months was 94.0% after mitral, 80% after aortic, 92% after double valve replacement, and 93.2% for the total group. The linearized incidence of valve relater death, prosthetic valve thrombosis, anticoagulant related hemorrhage, and reoperation was 1.00%/pt-yr, 0.51%/pt/yr, 0.51%/pt-yr, and 0.51%/pt-yr respectively. The 36 month rates of freedom from valve replated death, thromboembolism, endocarditis, anti-coagulant related hemorrages, and reoperation were 98.75%, 99.08%, 100%, 99.04%, and 99.08% respectively. The 36 month rate of freedom from all valve related complications and deaths including hospital mortality was 90.2%. These fact suggest that the CarboMedics heart valve has excellent short-term result, low incidence of valve-related complications and valve dysfunction, and additional long term follow up study is necessary.

Aortic valve repair with the use of tailored autologous pericardial extension to the native cusp was performed in one patient with rheumatic aortic valve incompetence. The patient was a 10-year-old girl with Grade II aortic regurgitation and tiny postoperative recannalization of the patent ductus arteriosus. The left aortic coronary cusp appeared to be a little thickened and a cicatrical shortening of the distance between the free edge of the cusp and its annular attachment. A semilunar shaped patch of autologous pericardium, treated with glutaraldehyde solution[6 minutes in 0.6% solution] was sutured along the free edge of the left coronry cusp. Postoperative recovery was uneventful. Echocardiography 8 months later showed Grade I aortic regurgitation. She is now conducting as usual life.

There are more patients with tracheal stenosis lately due to the increased use of tracheostomy and assisted ventilation. Recently we have experienced two cases of post tracheostomy tracheal stenosis and successfully performed circumferential resection and end-to-end anastomosis of the trachea. Postoperative tracheostomy was not performed. The postoperative courses were uneventful and they are now conducting an usual life.

A clinical study was performed on 64 cases of the esophageal diseases experienced at the Department of Thoracic & Cardiovascular Surgery of Kyungpook University Hospital from Jan. 1988 through Dec. 1992. The results were as follows: The most common esophageal disease was cancer which occurred in 37.5% of the total. In esophageal cancer patients, 24 cases were operated on and cancer resection was feasible in 19 cases with 2 cases of hospital death. The overall 1 year survival rate was 41.6% and the most favorable follow up result was revealed in stage I group. Esophageal stricture occurred in 22 cases and its causes were alkali and acid. The most common stricture site was mid-esphagus. Colon interposition was performed on 15 cases. Achalasia occured in 8 cases and was treated with modified Heller`s myotomy. Esophageal perforation occurred in 6 cases and its operative mortality rate was 16.6%. Two patients with congenital bronchoesophageal fistula were treated with surgical division. The first case, which occurred in an adult, is of Braimbridge,s typeII classification. The second one which occured in an child with sequestration, is of Braimbridge,s type IV classification. Diverticulectomy was performed in 1 case of esophageal diverticulum. Enucleation of tumor was performed in 1 case of esophageal leiomyoma.

Background: The aim of this study is to define the cardioprotective effects(functional and metabolic) of newly developed DelNido cardioplegic solution(containing plasma solution, mannitol, magnesium and lidocaine). Material and Method: This study assessed the function of rat hearts after itermittent infusion of DelNido cardioplegia with different preserving methods(Air or Icebox) for 2hours and perfusing the hearts on a Langendorff apparatus. Heart rate, left ventricular developed pressure(LVDP) and coronary flow, were measured at pre-ischemic, post-reperfusion 15min, 30min and 45min. Coronary flow was standardized to dry heart weight. Each weight was weighted to calculate water content. Creatine kinase-MB isoenzyme release was measured and ultrastructural assessment was done with electron microscopes. Result: DelNido group was better than St, Thomas group and Icebox group was better than Room-air group. Conclusion: DelNido cardioplegia have better myocardial protective effects than St. Thomas cardioplegia when they were preserved in the Room-air. But we can not tell the difference between Delnido cardiplegia with Air preserving method and St. Thomas cardioplegia with Icebox.

The management of chronic empyema remains still disturbing. These patients always have chances to exposure septic conditions. We presents 4 patients of chronic empyema with sepsis who underwent E-flap and Myoplasty with extrathoracic skeletal muscles between December 1994 and March 1997. Two patients who had BPF were treated with intercostal muscle flap as co-procedures. Intervals between first E-flap and second Myoplasty ranged from 5 to 10 months. There was no morbidity or mortality. We think these stepwise procedure offers a chance to terminate these debilitating diseases.

Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.
