Post-intensive care syndrome (PICS) affects the quality of life (QOL) survivors critical illness. Although PICS persists for a long time, longitudinal changes in each component and their interrelationships over time both remain unclear. This multicenter prospective study investigated 2-year trajectory its components as well factors contributing to deterioration or recovery mechanically ventilated patients with coronavirus disease 2019 (COVID-19), also attempted identify possible...

Post-intensive care syndrome (PICS) is an emerging problem in critically ill patients and the prevalence risk factors are unclear with severe coronavirus disease 2019 (COVID-19). This multicenter prospective observational study aimed to investigate of PICS ventilated COVID-19 after ICU discharge.Questionnaires were administered twice surviving who had required mechanical ventilation, concerning Barthel Index, Short-Memory Questionnaire, Hospital Anxiety Depression Scale scores. The for...

Objective: To implement early rehabilitation interventions by physical therapists is recommended. However, the effectiveness of for severe coronavirus disease 2019 (COVID-19) patients in prevention post-intensive care syndrome (PICS) unclear. We analyzed a multicenter prospective observational study (Post-Intensive Care outcomeS with COronaVIrus Disease 2019) to examine association between and PICS impairment.Methods: An analysis was performed on COVID-19 who were admitted intensive units...

Lung ultrasound (LUS), a rapid, bedside, goal-oriented diagnostic test, can be quantitatively assessed, and the scores used to evaluate disease progression. However, little data exists on predicting prolonged mechanical ventilation (PMV) successful extubation using serial LUS scores. We examined relationship of PMV with in patients severe coronavirus (COVID-19) by two types One score evaluated both pleura lung fields, while other assessed each separately (modified-LUS score). Both were...

Abstract Background Arterial lactate (AL) level is an important predictor of patient prognosis. AL and peripheral venous (PVL) in blood gas analysis have a low concordance rate, PVL cannot be used as substitute for AL. However, if the range can predicted from PVL, may alternative method predicting prognosis, risk arterial puncture complications with reduced. This could safe rapid test method. Methods was retrospective observational study 125 cases which performed on both infectious disease...

Abstract Background: Arterial lactate (AL) level is an important parameter used to predict patients’ prognosis. AL and peripheral venous (PVL) in blood gas analysis have a low concordance rate, PVL cannot be as substitute for AL. However, if the range can predicted from PVL, may alternative method of predicting patient prognosis, risk arterial puncture complications with reduced. This could become safe rapid test method. Methods: was retrospective observational study 143 cases which...

Abstract Background: Some patients with severe coronavirus disease (COVID-19) who present fibrosis on computed tomography (CT) require prolonged mechanical ventilation (PMV). Lung ultrasound (LUS), a rapid, bedside test, has been reported to have findings consistent those of CT. Thus, this study aimed assess whether serial LUS scores could predict PMV or successful extubation in COVID-19 patients. Methods: was performed for 20 consecutive at three time points: admission (day 1), after 48 h...
