Sepsis is a major cause of mortality and morbidity in critically ill patients. Procalcitonin (PCT) and C-reactive protein (CRP) are the most frequently used biomarkers in sepsis. We investigated changes in PCT and CRP concentrations in critically ill patients with sepsis to determine which biochemical marker better predicts outcome. We retrospectively analyzed 171 episodes in 157 patients with severe sepsis and septic shock who were admitted to the Samsung Medical Center intensive care unit from

This study aimed to investigate cognitive impairment and psychological distress of critically ill patients at discharge from intensive care unit (ICU). This study included 30 critically ill patients who had neither pre-existing dementia nor ongoing delirium. At ICU discharge, they performed a screening test for cognitive impairment (Mini-Cog test) and completed questionnaires for depression (Patient Health Questionnaire-2, PHQ-2) and for 4 stressful experiences during ICU stay including nightmar

BACKGROUND: Despite the high workload of mechanical ventilation, there has been a lack of studies on the association between nurse workforce and mortality in mechanically ventilated patients. We evaluated the association of the bed-to-nurse ratio with mortality in ventilated pediatric patients admitted to an intensive care unit (ICU). METHODS: We conducted a nationwide retrospective analysis by using the Korean National Health Insurance database, which categorizes the bed-to-nurse ratio into 9 g

BACKGROUND: Delirium frequently occurs among patients admitted to the intensive care unit (ICU). There is limited evidence to support interventions to treat or resolve delirium in patients who have already developed delirium. Therefore, the early recognition and prevention of delirium are important in the management of critically ill patients. OBJECTIVE: This study aims to develop and validate a delirium prediction model within 24 hours of admission to the ICU using electronic health record data

The optimal timing of enteral nutrition (EN) in sepsis patients is controversial among societal guidelines. We aimed to evaluate the evidence of early EN's impact on critically ill sepsis patients' clinical outcomes. We searched the MEDLINE, Embase, CINAHL, Cochrane Library, ClinicalTrials.gov, and ICTRP databases on 10 March 2023. We included studies published after 2004 that compared early EN versus delayed EN in sepsis patients. We included randomized controlled trials (RCTs), non-RCTs, cohor

Sepsis is a common cause of delirium in the intensive care unit (ICU). Recently, vitamin C and thiamine administration has been gaining interest as a potential adjunct therapy for sepsis. We investigated the impact of early vitamin C and thiamine administration on ICU delirium-free days among critically ill patients in septic shock. We performed a single-center, retrospective study of patients who visited the emergency department (ED) from January 2017 to July 2018. We categorized patients into

Recently, extracorporeal membrane oxygenation (ECMO) support has been increasingly applied in acute respiratory failure. The ECMO brings some advantages for enhancing the capacity of lung regeneration. Thus, the timing of determining irreversibility of the injured lung could be delayed. In this study, we experienced a case of prolonged maintenance of veno-venous ECMO for 104 days that resulted in native lung recovery. In this case, the initial empirical treatment showed no response within 4 week

OBJECTIVE: Delirium in the intensive care unit (ICU) may be a preventable risk factor for cognitive impairment or psychiatric problems. We aimed to evaluate the association between the presence of delirium during hospitalization involving ICU care and post-discharge cognitive impairment or psychiatric problems. DESIGN: A retrospective cohort study. SETTING: A database of nationwide insurance claims data. PATIENTS: All adult patients aged 18 years or older who were admitted to an ICU between Janu

PURPOSE: To assess the effect of continuous ketamine administration in patients admitted to medical and cardiac intensive care units (ICUs) and received mechanical ventilation support. METHODS: We conducted a retrospective cohort study between March 2012 and June 2020 at an academy-affiliated tertiary hospital. Adult patients who received mechanical ventilation support for over 24 h and continuous ketamine infusion for at least 8 h were included. The primary outcome was immediate hemodynamic saf

ABSTRACT: Cardiac output (CO) is an important parameter in fluid management decisions for treating hemodynamically unstable patients in intensive care unit. The gold standard for CO measurements is the thermodilution method, which is an invasive procedure with intermittent results. Recently, electrical impedance tomography (EIT) has emerged as a new method for noninvasive measurements of stroke volume (SV). The objectives of this paper are to compare EIT with an invasive pulse contour analysis (

The Korean version of the FSS-ICU showed excellent intra-rater and inter-rater reliability, internal consistency, and construct validity for medical ICU patients. The results of this study, along with prior publications, support that the FSS-ICU Korean version is a valid and reliable assessment tool for the ICU environment.Implications for rehabilitationIntensive care unit patients usually experience decreased muscle strength and physical function.The Korean version of the Functional Status Scor

Abstract Pulmonary artery catheterization (PAC) has been used as a clinical standard for cardiac output (CO) measurements on humans. On animals, however, an ultrasonic flow sensor (UFS) placed around the ascending aorta or pulmonary artery can measure CO and stroke volume (SV) more accurately. The objective of this paper is to compare CO and SV measurements using a noninvasive electrical impedance tomography (EIT) device and three invasive devices using UFS, PAC-CCO (continuous CO) and arterial
