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.

Ventilator-associated pneumonia (VAP) is a lung infection that develops in patients receiving mechanical ventilation. VAP contributes to about 50% of hospital-acquired pneumonia in ICU settings. One of the recommendation of the Institute of for Healthcare Improvement ventilator bundle is HOB elevation. HOB elevation affects shearing forces and makes higher risk for pressure injury development. Pressure injury (PI) is localized damage to the skin over a bony prominence. PI prevention guidelines recommend that HOB positioning should be lower to reduce risk for PI development which contradicts VAP prevention guidelines for the HOB between 30 and 45 degrees for ICU patients. This presents a care dilemma and tension. The purpose of this study was to perform a secondary data analysis using cumulative electronic health record data in order to determine the association of HOB elevation with VAP and PI in ICU patients. A secondary data analysis was conducted to determine whether HOB elevation is associated with VAP and PI. HOB elevation was not likely to be associated with VAP prevention whereas it was likely to be related to PI development. This is somewhat contrary to popular data and publications. Prospective cohort study is desired to inform us in an evidence-based fashion what actually is optimal HOB elevation for ventilated patients in ICU settings.

Purpose: The purpose of this study was to examine the effects of a closed endotracheal suction system(CES) on oxygen saturation, ventilator associated pneumonia(VAP), and nursing efficacy in mechanically ventilated patients. Method: This study was conducted in the intensive care unit of a University Hospital in Gwangju City. Data was collected from July to October, 2003. Seventy mechanically ventilated patients were randomly divided into two groups; 32 for CES and 38 for open endotracheal suction system(OES) protocol. Twenty one nurses were also involved to examine the nurses' attitude of usefulness about CES. Result: $SaO_2$ was significantly different between CES and OES. The incidence of VAP in CES was lower than that of OES. Nursing efficacy was related to time, cost, and usefulness of the suction system. Time of suctioning in CES was shorter than that of OES. CES also contributed significantly to lower the cost of treatment than OES. The usefulness score of CES increased after 6 months of use. Conclusion: CES prevented VAP, was cost effective, and a safe suctioning system. CES can be used with patients with sensitivity to hypoxygenation and with a high risk of VAP.

Recently, several researches indicated the relationship between oral condition and respiratory disease such as pneumonia and chronic obstructive pulmonary disease (COPD). Respiratory disease is known as common chronic disease in the elderly increasing mortality and morbidity. In this study, we have reviewed the association between oral disease and respiratory disease in the elderly. The related data were searched and collected from abroad and domestic studies. The studies included the randomized controlled clinical trials (RCTs), longitudinal, cohort, case-control, and systematic review studies. With the data from the studies, we concluded that poor oral hygiene or periodontal disease can influence the pneumonia in the elderly. Further studies will be needed to investigate the association between oral disease and COPD.

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: This study is to evaluate the effect of systemic corticosteroid on the clinical outcomes and the occurrence of complications in mechanical ventilated patients with severe community-acquired pneumonia (CAP). Methods: We retrospectively assessed the clinical outcomes and complications in patients with severe CAP admitted to ICU between March 1, 2003 and July 28, 2009. Outcomes were measured by hospital mortality after ICU admission, duration of mechanical ventilation (MV), ICU, and hospital stay. Complications such as ventilator associated pneumonia (VAP), catheter related-blood stream infection (CR-BSI), and upper gastrointestinal (UGI) bleeding during ICU stay were assessed. Results: Of the 93 patients, 36 patients received corticosteroids over 7 days while 57 patients did not receive corticosteroids. Age, underlying disease, APACHE II, PSI score, and use of vasopressor were not different between two groups. In-hospital mortality was 30.5% in the steroid group and 36.8% in the non-steroid group (p>0.05). The major complications such as VAP, CR-BSI and UGI bleeding was significantly higher in the steroid group than in the non-steroid group (19.4% vs. 7%, p<0.05). The use of steroids and the duration of ICU stay were significantly associated with the development of major complications during ones ICU stay (p<0.05). Conclusion: Systemic corticosteroid in patients with severe CAP requiring mechanical ventilation may have no beneficial effect on clinical outcomes like duration of ICU stay and in-hospital mortality but may contribute to the development of ICU acquired complications.
