목 적 : 최근 신생아학의 발달과 신생아 집중 치료의 발달로 기관내 삽관 후 인공 환기요법 치료가 빈번하게 이루어져 호흡곤란증이 있는 신생아의 사망률은 감소된 반면 이에 따른 여러 합병증이 병발할 가능성이 높아지게 되었다. 이에 저자들은 인공 환기요법을 사용한 신생아에서 VAP의 발생빈도와 위험요인 및 주된 균주에 대해 알아보았다. 방 법 : 2000년 1월 1일부터 2003년 6월 30일까지 한림대학교 강남성심병원 신생아 집중치료실에 입원하여 인공 환기요법을 사용한 신생아 50명을 대상으로 하여 입원 기록지를 후향적으로 분석하였다. VAP의 진단은 기관내 삽관 당시에는 폐렴이 보이지 않으나 기관내 삽관 후 최소 48시간 경과 후 흉부 방사선상 새롭게 침윤이 발생한 경우로 정의하였다. 상기 조건에 만족하는 환아 13명을 VAP군으로, 만족하지 않는 환아 37명을 대조군으로 분류하였다. 결 과 : 인공 환기요법을 사용했던 환아 50명 중 VAP의 발생빈도는 26.0%(13명)였다. 동맥관 개존증과 뇌실내 출혈이 VAP 발생과 연관이 있었고 재태연령, 출생체중, 1분 및 5분 Apgar 점수 및 호흡곤란 증후군, 기관지폐 이형성증, 미숙아 망막증, 패혈증, 급성 신부전, 폐출혈, 공기 누출 증후군 등과는 연관이 없었다. 본 연구에서는 총 12균주가 동정되었는데 MR-CNS 4례(33.3%), E. cloacae 3례(25.0%), P. aeruginosa 2례(16.7%), MRSA 1례(8.3%), Acinetobacter baumanii 1례(8.3%), K. pneumoniae 1례(8.3%)로 MR-CNS가 가장 많았다. 결 론 : 본원 신생아 집중치료실에서 인공 환기요법 치료 후 발생한 폐렴의 빈도는 26.0%이며 MR-CNS가 가장 많이 배양되였다. 기관삽관 말단의 배양은 VAP의 정확한 진단을 위해서는 적절치 않을 수 있으나 신생아에게 필요한 침습적이지 않고 정확한 방법에 대한 연구가 필요하다고 생각된다.

Background: Recent developments in surgical techniques and hospital care have led to improved outcomes following total anomalous pulmonary venous return (TAPVR) repair. However, the surgical repair of TAPVR remains associated with a high risk of mortality and need for reoperation. We conducted this retrospective study to evaluate mid-term outcomes following in situ TAPVR repair without total circulatory arrest (TCA), and to identify the risk factors associated with surgical outcomes. Methods: We retrospectively reviewed 29 cases of surgical intervention for TAPVR conducted between April 2000 and July 2015. All patients were newborns or infants who underwent in situ TAPVR repair without TCA. Results: Four anatomic subtypes of TAPVR were included in this study: supracardiac (20 cases, 69.0%), cardiac (4 cases, 13.8%), infracardiac (4 cases, 13.8%), and mixed (1 case, 3.4%). The median follow-up period for all patients was 42.9 months. Two (6.9%) early mortalities occurred, as well as 2 (6.9%) cases of postoperative pulmonary venous obstruction (PVO). Preoperative ventilator care (p=0.027) and preoperative PVO (p=0.002) were found to be independent risk factors for mortality. Conclusion: In situ repair of TAPVR without TCA was associated with encouraging mid-term outcomes. Preoperative ventilator care and preoperative PVO were found to be independent risk factors for mortality associated with TAPVR repair.

배경: 흉부 외상 환자에 있어서 폐렴은 가장 흔한 감염증이며, 진단 및 치료의 발전에도 불구하고 이환율과 치사율을 높이는 매우 심각한 합병증이다. 본 연구는 흉부 외상 환자 중 인공호흡기 치료를 하였던 환자에서 폐렴의 임상 양상을 분석하고 그 원인 인자를 파악하고자 하였다. 대상 및 방법: 2001년 1월부터 2006년 12월까지 흉부 외상에 의해 인공호흡기 치료를 시행한 78명의 환자를 대상으로 하였다. 대상 환자 중 폐렴이 발생한 38예를 I군으로,폐렴이 발생하지 않은 40예를 II군으로 나누어 비교 분석하였다. 각 군의 병원 도착시 혈역학적 소견 및 이학적 소견, 혈액학적 소견, 외상의 원인, 흉부 외상의 형태 및 그 정도, 동반 외상, 기저 질환, 인공호흡기 이용 기간, 중환자실 입원 기간 그리고 사망률 등을 후향적으로 조사하였다. 결과: 대상 환자는 남자 57명, 여자 21명이었으며, 평균 연령은 $48.3{\pm}19.9$세였다. 흉부외상에 의해 인공호흡기 치료를 시행한 환자의 48.7%에서 외상 후 페렴이 발생하였고, 사망률은 I군에서 21.0%, II군에서 2.5%로 II군에서 현저하게 높았다. 내원시 혈역학적 소견 상 수축기 혈압이 90 mmHg 이하의 쇼크 상태로 인해 수축촉진약(inotropics)을 사용한 경우는 I군에서 24예(63.1)로 II군의 10예(25%)보다 유의하게 많았으며(p=0.001), C-Reactive Protein(CRP) 치는 I군에서 $11.3{\pm}7.8$으로 II군의 $6.4{\pm}7.3$에 비해 유의하게 높았다(p=0.006). 인공호흡기 이용기간 및 중환자실 입원 기간은 I군에서 각각 17.4일, 21.7일로 II군의 6.5일, 9.7일에 비해 유의하게 길었다(p<0.001). 결론: 외상 후 폐렴의 발생은 인공호흡기 이용 기간 및 중환자실 입원 기간이 긴 환자에서 많이 발생하였으며 그외 내원시 측정한 CRP 치가 높은 경우, 쇼크 상태로 인해 수축촉진약(inotropics)를 사용한 경우에 많이 발생하였다. 흉부 외상 환자의 치료 시 이런 요인들을 고려한다면 폐렴의 예방 및 치료에 도움이 될 것으로 생각된다.

Purpose: Chest injuries in multiple trauma patients are major predisposing factor for increased length of stay in intensive care unit, prolonged mechanical ventilator, and respiratory complications such as pneumonia. The aim of this study is the evaluation of lung injury score as a risk factor for prolonged management in intensive care unit (ICU). Methods: Between June to August in 2011, 46 patients admitted to shock and trauma center in our hospital and 24 patients had associated chest damage without traumatic brain injury. Retrospectively, we calculated injury severity score (ISS), lung injury score, and the number of fractured ribs and performed nonparametric correlation analysis with length of stay in ICU and mechanical ventilator support. Results: Calculated lung injury score(<48 hours) was median 1(0-3) and ISS was median 30(8-38) in study population. They had median 2(0-14) fractured ribs. There were 2 bilateral fractures and 2 flail chest. Ventilator support was needed in 11(45.8%) of them for median 39 hours(6-166). The ISS of ventilator support group was median 34(24-34) and lung injury score was median 1.7(1.3-2.5). Tracheostomy was performed in one patient and it was only complicated case and ICU stay days was median 9(4-16). In correlation analysis, Lung injury score and ISS were significant with the length of stay in ICU but the number of fractured ribs and lung injury score were predicting factors for prolonged mechanical ventilator support. Conclusion: Lung injury score could be a possible prognostic factor for the prediction of increased length of stay in ICU and need for mechanical ventilator support.

Background: Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are significant public health issues in the world, but the epidemiological data pertaining to HAP/VAP is limited in Korea. The objective of this study was to investigate the characteristics, management, and clinical outcomes of HAP/VAP in Korea. Methods: This study is a multicenter retrospective cohort study. In total, 206,372 adult patients, who were hospitalized at one of the 13 participating tertiary hospitals in Korea, were screened for eligibility during the six-month study period. Among them, we included patients who were diagnosed with HAP/VAP based on the Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) definition for HAP/VAP. Results: Using the IDSA/ATS diagnostic criteria, 526 patients were identified as HAP/VAP patients. Among them, 27.9% were diagnosed at the intensive care unit (ICU). The cohort of patients had a median age of 71.0 (range from 62.0 to 79.0) years. Most of the patients had a high risk of aspiration (63.3%). The pathogen involved was identified in 211 patients (40.1%). Furthermore, multidrug resistant (MDR) pathogens were isolated in 138 patients; the most common MDR pathogen was Acinetobacter baumannii. During hospitalization, 107 patients with HAP (28.2%) had to be admitted to the ICU for additional care. The hospital mortality rate was 28.1% in the cohort of this study. Among the 378 patients who survived, 54.2% were discharged and sent back home, while 45.8% were transferred to other hospitals or facilities. Conclusion: This study found that the prevalence of HAP/VAP in adult hospitalized patients in Korea was 2.54/1,000 patients. In tertiary hospitals in Korea, patients with HAP/VAP were elderly and had a risk of aspiration, so they were often referred to step-down centers.

Background: Ventilator-associated pneumonia (VAP) is a common disease that may contribute to morbidity and mortality among trauma patients in the intensive care unit (ICU). This study evaluated the associations between trauma factors and the development of VAP in ventilated patients with multiple rib fractures. Methods: We retrospectively and consecutively evaluated 101 patients with multiple rib fractures who were ventilated and managed at our hospital between January 2010 and December 2015, analyzing the associations between VAP and trauma factors in these patients. Trauma factors included sternal fracture, flail chest, diaphragm injury, traumatic aortic dissection, combined cardiac injury, pulmonary contusion, pneumothorax, hemothorax, hemopneumothorax, abbreviated injury scale score, thoracic trauma severity score, and injury severity score. Results: Forty-six patients (45.5%) had at least 1 episode of VAP, 10 (21.7%) of whom died in the ICU. Of the 55 (54.5%) patients who did not have pneumonia, 9 (16.4%) died in the ICU. Using logistic regression analysis, we found that VAP was associated with severe lung contusion (odds ratio, 3.07; 95% confidence interval, 1.12 to 8.39; p=0.029). Conclusion: Severe pulmonary contusion (pulmonary lung contusion score 6-12) is an independent risk factor for VAP in ventilated trauma patients with multiple rib fractures.

목적: 인공 환기요법 관련 폐렴은 중증 소아 환자에게 있어서 심각한 위협이 될 수 있다. 소아 환자에서 Stenotrophomonas maltophilia에 의한 인공 환기요법 관련 폐렴에 대한 연구는 부족한 실정이다. 본 연구는 소아 중환자에서 S. maltophilia에 의한 인공 환기요법 관련 폐렴의 임상적 특성을 알아보고자 하였다. 방법: 2008년 1월 1일부터 2012년 12월 31일까지 삼성서울병원 소아중환자실에 입원한 S. maltophilia로 인한 인공 환기요법 관련 폐렴에 걸린 18세 이하 소아들의 의무 기록을 기초로 한 후향적 연구를 시행하였다. 결과: S. maltophilia로 인한 인공 환기요법 관련 폐렴으로 진단 받은 총 31명의 환자가 연구 대상에 포함되었다. 연령 중앙값은 8개월(범위, 0.5개월-16.6세)이고, 남자는 13명(40.6%)이었다. 환자들의 만성질환 분포는 심혈관질환(n=11, 34.4%), 혈액종양질환(n=7, 25.0%), 신경질환(n=4, 12.5%), 호흡기질환(n=3, 9.4%) 그리고 기타(n=4, 12.5%)이었다. 인공 환기요법 관련 폐렴을 진단하기 전 인공 환기요법을 하였던 기간의 중앙값은 14일(범위, 4-256일)이었다. S. maltophilia 인공 환기요법 관련 폐렴후 30일 이내 사망률은 12.5% (4/32) 이었다. 결론: S. maltophilia는 중증 소아 환자에서 인공 환기요법 관련 폐렴의 원인균으로 반드시 고려되어야 할 대상이다. 경험적 광범위 베타-락탐 항생제를 사용하고 있음에도 불구하고 환자 상태가 나빠지고 있다면, 항생제 선택에서 S. maltophila의 감염을 고려해야 할 것으로 사료된다.

Purpose: The purpose of this study was to examine the effect of tooth-brushing oral care on oral health and ventilator-associated pneumonia of patients in Intensive Care Unit (ICU). Methods: A total of 74 participants were recruited from a medical, surgical, or neurosurgical ICU at S Hospital in Seoul, Korea, from September of 2010 to January of 2011. An experimental group (n= 36) received oral care with tooth-brushing while a control group (n=38) received oral care with cotton ball and gauze. In both group, the oral care was done three times a day at least one minute for 7 days. Oral health was examined by the Modified Oral Assessment Guide before the intervention and each night. Results: There is no difference between the groups in aspect of passage of time (p = .603), interaction between time and intervention (p =.300), the performance intervention (p = .766), and the incidence of VAP (p = .486). Conclusion: The effect of oral care with tooth-brushing on oral health and VAP was not different from that of usual oral care in ICU. However, further study is necessary due to high attrition in this study.
