Abstract

BACKGROUND AND AIMS:We hypothesized that mechanically ventilated cirrhotic patients not only have poor outcomes, but also that certain clinical variables are likely to be associated with mortality. We aimed to describe the predictors of mortality in these patients. METHODS:This observational study examined 113 mechanically ventilated cirrhotic patients cared for at our institution between July 1, 2014, and February 28, 2018. We performed bivariate and multivariate analyses to identify risk factors for mortality on mechanical ventilation and created an equation to calculate probability of mortality based on these variables. RESULTS:Seventy percent of patients had a history of a decompensating event. Altered mental status was the most frequently encountered indication for intubation (46%). 53% patients died on mechanical ventilation. After controlling for variables associated with increased mortality, multivariate analysis revealed that vasopressor use was the strongest predictor of mortality on mechanical ventilation (OR = 9.3) followed by sepsis (OR = 4.1). A formula with an area under the curve of 0.85 was obtained in order to predict the probability of mortality for cirrhotic patients on mechanical ventilation (available at https://medweb.musc.edu/mvcp/). This model (AUC = 0.85) outperformed the CLIF-SOFA score (AUC = 0.68) in predicting mortality in this cohort. CONCLUSION:Cirrhotic patients requiring mechanical ventilation have an extremely poor prognosis, and in patients requiring vasopressors, having a history of decompensation, sepsis or low albumin, mortality is higher. Our data points to the clinical variables should be considered in the medical management of these patients and provide physicians with a formula to predict the probability of mortality.

摘要

背景和目的: 我们假设机械通气肝硬化患者不仅预后差,而且某些临床变量可能与死亡率相关。我们旨在描述这些患者死亡率的预测因素。 方法: 这项观察性研究检查了 2014年7月1日至 2018年2月28日在我们机构护理的 113 例机械通气肝硬化患者。我们进行了双变量和多变量分析,以确定机械通气死亡率的危险因素,并根据这些变量创建了计算死亡率概率的方程。 结果: 70% 的患者有失代偿事件史。精神状态改变是插管最常遇到的指征 (46%)。53% 例患者死于机械通气。在控制了与死亡率增加相关的变量后,多变量分析显示血管加压药的使用是机械通气死亡率的最强预测因子 (or = 9.3),其次是脓毒症 (or = 4.1)。为了预测肝硬化机械通气患者的死亡率,获得了曲线下面积为 0.85 的公式 (可在 https://medweb.musc.edu/mvcp/ 获得)。该模型 (auc = 0.85) 在预测该队列死亡率方面优于 CLIF-SOFA 评分 (auc = 0.68)。 结论: 肝硬化需要机械通气的患者预后极差,在需要升压药的患者中,有失代偿、脓毒症或低白蛋白史的患者死亡率更高。我们的数据指出,在这些患者的医疗管理中应该考虑临床变量,并为医生提供预测死亡率概率的公式。

METHODS:Background: The hospitalization of patients treated in the intensive care unit (ICU) in 5&#8722;15% of cases is associated with the occurrence of a complication in the form of ventilator-associated pneumonia (VAP). Purpose: Retrospective assessment of risk factors of VAP in patients treated at ICUs in the University Hospital in Krakow. Methods: The research involved the medical documentation of 1872 patients treated at the ICU of the University Hospital in Krakow between 2014 and 2017. The patients were mechanically ventilated for at least 48 h. The obtained data were presented by qualitative and quantitative analysis (%). The qualitative variables were compared using the Chi2 test. Statistically significant was the p < 0.05 value. Results: VAP was demonstrated in 23% of all patients treated in ICU during the analyzed period, and this infection occurred in 13% of men and 10% of women. Pneumonia associated with ventilation was found primarily in patients staying in the ward for over 15 days and subjected to intratracheal intubation (17%). A statistically significant was found between VAP and co-morbidities, e.g., chronic obstructive pulmonary disease, diabetes, alcoholism, obesity, the occurrence of VAP and multi-organ trauma, hemorrhage/hemorrhagic shock, and fractures as the reasons for admitting ICU patients. Conclusions: Patients with comorbidities such as chronic obstructive pulmonary disease, obesity, diabetes, and alcoholism are a high-risk group for VAP. Particular attention should be paid to patients admitted to the ICU with multi-organ trauma, fractures, and hemorrhage/hemorrhagic shock as patients predisposed to VAP. There is a need for further research into risk factors for non-modifiable VAP such as comorbidities and reasons for ICU admission in order to allow closer monitoring of these patients for VAP.

METHODS::Backgroud Severe pneumonia is one of the most common causes for mechanical ventilation. We aimed to early identify severe pneumonia patients with high risk of extubation failure in order to improve prognosis. Methods From April 2014 to December 2015, medical records of intubated patients with severe pneumonia in intensive care unit were retrieved from database. Patients were divided into extubation success and failure groups, and multivariate logistic regressions were performed to identify independent predictors for extubation failure. Results A total of 125 eligible patients were included, of which 82 and 43 patients had extubation success and failure, respectively. APACHE II score (odds ration (OR) 1.141, 95% confident interval (CI) 1.022-1.273, P = 0.019, cutoff at 17.5), blood glucose (OR 1.122, 95%CI 1.008-1.249, P = 0.035, cutoff at 9.87mmol/L), dose of fentanyl (OR 3.010, 95%CI 1.100-8.237, P = 0.032, cutoff at 1.135mg/d), and the need for red blood cell (RBC) transfusion (OR 2.774, 95%CI 1.062-7.252, P = 0.037) were independent risk factors for extubation failure. Conclusions In patients with severe pneumonia, APACHE II score > 17.5, blood glucose > 9.87mmol/L, fentanyl usage > 1.135mg/d, and the need for RBC transfusion might be associated with higher risk of extubation failure.

METHODS:PURPOSE:To assess the association between the duration of mechanical ventilation during post resuscitation care and 30-day survival after cardiac arrest. METHODS:We conducted a retrospective observational study using data from two national registries. Comatose cardiac arrest patients admitted to general intensive care in Swedish hospitals between 2011 and 2016 were eligible. Based on the median duration of mechanical ventilation for patients who did not survive to hospital discharge, used as a proxy for the endurance of post resuscitation care, the hospitals were divided into four ordered groups for which association with 30-day survival was analyzed. RESULTS:In total, 5.113 patients in 56 hospitals were included. Median duration of mechanical ventilation for patients who did not survive to hospital discharge ranged from 17 hours in hospital group 1 to 51 hours in hospital group 4. After adjustment for baseline characteristics, 30-day survival in the entire cohort was positively and independently associated with ordered hospital group: (adjusted odds ratio (95%CI); 1.12 (1.02,1.23); p = 0.02). Thus, hospitals with a longer duration of mechanical ventilation among non-survivors had better survival rate among patients admitted to ICU after a cardiac arrest. However, in a secondary analysis restricted to patients with length of stay in the intensive care unit ≥ 48 hours, there was no significant association between 30-day survival and ordered hospital group. CONCLUSION:A tendency for longer duration of post resuscitation care in the ICU was associated with higher 30-day survival in comatose patients admitted to intensive care after cardiac arrest.
