BACKGROUND: Impaired cerebral autoregulation and cerebral hypoperfusion may play a critical role in the high morbidity and mortality in patients with sepsis-associated encephalopathy (SAE). Bedside assessment of cerebral autoregulation may help individualize hemodynamic targets that optimize brain perfusion. We hypothesize that near-infrared spectroscopy (NIRS)-derived cerebral oximetry can identify blood pressure ranges that enhance autoregulation in patients with SAE and that disturbances in autoregulation are associated with severity of encephalopathy...

OBJECTIVE: Training in critical care ultrasonography is an essential tool in critical care medicine and recommended for fellowship programs in pulmonary and critical care medicine. Major barriers to implementing competency-based training in individual fellowship programs include a lack of expert faculty, time, and funding. Our objective was to investigate whether regional collaboration to deliver an introductory critical care ultrasonography course for fellows might overcome these barriers while achieving international training standards...

INTRODUCTION: We previously showed that a "10-hour daytime on-site" and "nighttime (NT) on-call" staffing strategy was associated with higher mortality for intensive care unit (ICU) patients admitted during NT than it was for patients admitted during office hours (OH). In here, we evaluated the clinical effects of a 24-hour intensivist staffing model. METHODS: We formed an intervention group of 3034 consecutive ICU patients hospitalized from January 2013 to December 2015, and a control group of 2891 patients from our previous study (2009-2011)...

PURPOSE: The objective of this study was to compare the incidence of acute kidney injury (AKI) among critically ill patients receiving combination therapy with vancomycin plus piperacillin-tazobactam (VPT) against patients receiving vancomycin plus cefepime (VC). METHODS: A retrospective cohort study of adult patients admitted to an intensive care unit between September 2012 and December 2016 was conducted. Patients were included if they received combination therapy with VPT or VC for ≥48 hours...

BACKGROUND: Cardiogenic shock (CS) is the most life-threatening manifestation of acute heart failure. Its complexity and high in-hospital mortality may justify the need for invasive monitoring with a pulmonary artery catheter (PAC). METHODS: Patients with CS included in the CardShock Study, an observational, prospective, multicenter, European registry, were analyzed, aiming to describe the real-world use of PAC, evaluate its impact on 30-day mortality, and the ability of different hemodynamic parameters to predict outcomes...

Sepsis is a major cause of morbidity and mortality worldwide. With the advance of medical care, the mortality of sepsis has decreased in the past decades. Many treatments and diagnostic tools still lack supporting evidence. We conducted a retrospective population-based cohort study with propensity score matched subcohorts based on a prospectively collected national longitudinal health insurance database in Taiwan. Severe sepsis-associated hospital admissions from 2000 to 2011 based on International Classification of Diseases, Ninth Revision, Clinical Modification codes of infections and acute organ dysfunction were identified...

BACKGROUND: The purpose of this study was to examine how frequently invasive intensive care unit (ICU) treatments are delivered to critically ill patients despite clinicians' impressions that ICU care may be nonbeneficial. METHODS: Patients admitted to the medical ICU of an academic public hospital were prospectively categorized according to guidelines from the Society of Critical Care Medicine which classifies patients based on severity of illness and likelihood of recovery (categories 1-4)...

INTRODUCTION: Although prognostic prediction scores for pneumonia such as CURB-65 score or pneumonia severity index (PSI) are widely used, there were a few studies in very elderly patients. The aim of the study was to validate prognostic prediction scores for severe pneumonia and investigate risk factors associated with in-hospital mortality of severe pneumonia in very elderly patients. METHODS: During the 6-year study period (from October 2012 to May 2018), 160 patients aged 80 or older admitted to medical intensive unit were analyzed retrospectively...

BACKGROUND: Although many performance-based measures assess patients' physical function in intensive care unit (ICU) survivors, to our knowledge, there are no patient-reported ICU rehabilitation-specific measures assessing function. We developed the Patient-Reported Functional Scale-ICU (PRFS-ICU), which measures patients' perceptions of their ability to perform 6 activities (rolling, sitting edge of bed, sit-to-stand and bed-to-chair transfers, ambulation, and stair climbing). Each item is scored from 0 (unable) to 10 (able to perform at pre-ICU level) to a maximum of 60...

Acute kidney injury (AKI) is a common and serious medical condition associated with significant increases in morbidity, mortality, and cost of care. Because of the high incidence and poor outcomes associated with AKI, there has been significant interest in the development of new therapies for the prevention and treatment of the disease. A lack of efficacy in drug trials led to the concern that AKI was not being diagnosed early enough for an effective intervention and that a rise in serum creatinine itself is not a sensitive-enough marker...

BACKGROUND: Currently, it remains controversial whether the Sepsis-3 definition provides the most appropriate criteria for clinical use. The purpose of this study was to compare between the Sepsis-2 and Sepsis-3 definitions using Japan's nationwide registry. METHODS: Data were obtained from a multicenter registry conducted at 42 intensive care units (ICUs) throughout Japan, in which patients received treatment for severe sepsis or septic shock between January 2011 and December 2013...

PURPOSE: Conflicting results exist regarding the efficacy of N-acetyl cysteine (NAC) in sepsis treatment. A pivotal factor affecting the therapeutic potency of NAC in sepsis is timing and dosing of its infusion. We aimed to assess the effect of NAC on redox status of patients with sepsis and to compare its efficacy in intermittent and continuous infusion with the objective of developing the infusion regimen and optimizing the timing. MATERIALS AND METHODS: A prospective, randomized clinical trial was designed to compare the antioxidative effect of NAC in intermittent infusion group (IV: 25 mg/kg bolus and then 25 mg/kg/8 hours 3 times) and continuous infusion group (IV: 25 mg/kg bolus and then 75 mg/kg over 24 hours) in 60 critically ill patients with sepsis (20 patients in each group)...

RATIONALE: The feasibility and clinical outcomes of conservative fluid management after sepsis resuscitation remain unknown. OBJECTIVES: To evaluate the effect of a conservative fluid management protocol on fluid balance and intensive care unit (ICU)-free days among patients with sepsis. METHODS: In a single-center phase II/III randomized trial, we enrolled adults with suspected infection, ≥2 systemic inflammatory response syndrome criteria, and either shock (mean arterial pressure <60 mm Hg or vasopressors) or respiratory insufficiency (mechanical ventilation or oxygen saturation <97% and fraction of inspired oxygen ≥0...

OBJECTIVE: The elevation of serum cardiac troponin I (TNI) in patients with nontraumatic subarachnoid hemorrhage (ntSAH) is a well-known phenomenon. However, the relation between elevated TNI and different cardiopulmonary parameters (CPs) within the first 24 hours after ntSAH is unknown. The present study was conducted to investigate the association between TNI and different CP in patients with ntSAH within the first 24 hours of intensive care unit (ICU) treatment. PATIENTS AND METHODS: We retrospectively analyzed a consecutive group of 117 patients with ntSAH admitted to our emergency department between January 2008 and February 2017...

OBJECTIVE: To evaluate the effect of high-flow nasal cannula oxygen (HFNO) therapy on hospital length of stay (LOS) and postoperative pulmonary complications (PPCs) in adult postoperative patients. DATA SOURCES: PubMed, Embase, the Cochrane Library, Web of Science of Studies, China National Knowledge Index, and Wan Fang databases were searched until July 2018. STUDY SELECTION: Randomized controlled trials (RCTs) comparing HFNO with conventional oxygen therapy or noninvasive mechanical ventilation in adult postoperative patients were included...

PURPOSE: Passive leg raise (PLR), in combination with technologies capable of capturing stroke volume changes, has been widely adopted in the management of shock. However, dedicated evaluation of safety, feasibility, and receptiveness of patients and nursing staff to PLR maneuver is missing. METHODS: A noninterventional, prospective trial recruited adult patients with onset of undifferentiated shock within 24 hours with persistent vasopressor requirements despite fluid resuscitation...

STUDY OBJECTIVE: Vasodilatory shock is the most common type of shock. Catecholamine vasopressors are the cornerstone of hemodynamic therapy but carry risks. Angiotensin II (AT2 ) was recently approved, and other novel agents (selepressin and terlipressin) are under investigation and used outside the United States (terlipressin). We performed a systematic review to summarize the efficacy and safety of these novel vasopressors and to offer guidance on their appropriate use. DESIGN: Systematic review of controlled trials...

BACKGROUND: Agitation is common in the intensive care unit (ICU). Although antipsychotics are frequently used as first-line therapy, chlorpromazine has fallen out of favor due to risk of cardiovascular complications and severe hypotension. Although chlorpromazine is used anecdotally, there is a lack of data regarding its safety and effectiveness. The objective of this study was to investigate the use of intravenous (IV) chlorpromazine for agitation in the ICU setting. METHODS: A retrospective review was performed at a tertiary care academic medical center...

BACKGROUND: Critically ill patients are at high risk for pulmonary embolism (PE). Specific PE prediction rules have not been validated in this population. The present study assessed the Wells and revised Geneva scoring systems as predictors of PE in critically ill patients. METHODS: Pulmonary computed tomographic angiograms (CTAs) performed for suspected PE in critically ill adult patients were retrospectively identified. Wells and revised Geneva scores were calculated based on information from medical records...
