Effectiveness of Formal Dysphagia Screening for Stroke Patients / 대한연하장애학회지

Objective@#Early identification of dysphagia after stroke helps in preventing aspiration pneumonia. However, data are limited regarding the effectiveness of formal dysphagia screening for reducing the risk of aspiration pneumonia.The current study evaluates the effectiveness of formal dysphagia screening in stroke patients, to prevent future episodes of aspiration pneumonia. @*Methods@#The stroke registry of a tertiary hospital was retrospectively reviewed. We compared clinical variables and the incidence of aspiration pneumonia of patients hospitalized between 2014 and 2015 after formal screening was implemented, and patients hospitalized in 2011 when no established dysphagia screening protocol was in place.Additionally, we identified the incidence of pneumonia according to stroke severity, and evaluated the association with results obtained for incidence of pneumonia and dysphagia screening. @*Results@#A total of 2,902 patients were identified to have suffered acute stroke (2,018 who underwent formal dysphagia screening; 884 without screening). Patients with formal dysphagia screening developed pneumonia less frequently than patients not administered screening (1.3% with formal screening vs. 3.4% no formal screening, P＜0.001).Pneumonia was significantly lower in patients with moderate and severe stroke who underwent formal dysphagia screening. Furthermore, failure of the dysphagia screening test, presentation with severe dysarthria, and conditions where dysarthria could not be evaluated, were independent predictors of pneumonia among patients who underwent formal screening. @*Conclusion@#Our findings demonstrate the association of formal dysphagia screening with reduced risk of poststroke aspiration pneumonia, and indicates the efficacy of the procedure in identifying patients at higher risk of contracting pneumonia.

Prognostic Value of APACHE 3 Score System in the Patients with Hemoptysis Who ware Admitted at Medical Intensive Care Unit / 대한내과학회지

BACKGROUND: Massive hemoptysis is one of the major medical emergency with high risk of mortality. Though the best predictor of mortality associated with hemoptysis appears to be the amount of bleeding within the first 24 hours, catastrophic hemorrhage could be occurred to the patients who were apparently in a stable condition with scanty hemoptysis at the time of admission. We evaluated APACHE III score system to find if it could be a prognostic index that can predict the mortality of the patients with hemoptysis. METHODS: We identified all the patients who had admitted with hemoptysis in the Medical Intensive Care Unit of Asan Medical Center between May 25, 1989, and July 31, 1995. A retrospective analysis was done in 66 patients with hemoptysis on APA- CHE III score. RESULTS: The overall mortality rate was 17.4% (12/69). In univariate analysis of possible prognostic factors, independent predictors of mortality were age(P=0.016), amount of hemoptysis(P=0.012), AaDO2 (P=0.017), requirement of transfusion(P=0.036), mechanical ventilatory care(P<0.05) and APACHE III score(P=0.02), In multivariate analysis with sex, age, amount of hemoptysis, AaDO2, requirement of transfusion and APACHE III score, APACHE III score was the only independent predictor of mortality(P=0.015, odd ratio=19.3, 95% confidence interval, 3.4 to 249.7) CONCLUSION: APACHE IU score may be a clinically significantly important independent predictor of outcome in the patients with hemoptysis. In addition, invasive procedure, such as bronchial artery embolizaticn or operation, could be considered in advance in the patients with more than 30 points of APACHE III.

Predcitors of the Development of Acute Respiratory Distress Syndrome in the Patients with Acute Pancreatitis / 결핵

BACKGROUND: Though acute respiratory distress(ARDS) often occurs in the early stage of severe acute pancreatitis and significantly contributed to the mortality of the condition, the characteristics of the group who develops ARDS in the patients with acute pancreatitis have not been fully found. The objective of this investigation was to identify predictable factors which distinguish a group who would develop ARDS in the patients with acute pancreatitis METHODS: A retrospective analysis of 94 cases in 86 patients who were admitted the Medical Intensive Care Unit with acute pancreatitis was done ARDS were developed in 3 cases among them (13.8%). The possible clinical factors related to the development were analyzed using univariate analysis and X(2)-test. RESULTS: The risk of ARDS development was increased in the patients with abonormal findings of chest X-ray at admission compared to the patients with normal chest X-ray (P<0.05). The risk was also increased according to the sevecrity index score in abdominal computed tomography at the time of admission (p<0.05). The higher APACHE III score of the first day of admission, the more risk increment of ARDS development was observed (p<0.01). Patients with more than one points of Murray's lung injury score showed higher risk of ARDS compared to the patients with 0 points of that. The patients with sepsis and the patients with more than three organ dysfunction at admission had 3.5 times and 23.3 times higher risk of the development, of ARDS compared to the patients without sepsis and without organ failure in each (p<0.05, p<0.01). CONCLUSION: The risk of ARDS development would k higher in the acute pancreatitis patients with abnormal chest X-ray, higher CT severity index, higher APACHE HI or Murray's lung injury score, accompanying sepsis, and more than three organ failure at admission
