BACKGROUND: We performed a systematic review of randomized controlled studies evaluating any drug, technique or device aimed at improving the success rate or safety of tracheal intubation in the critically ill. METHODS: We searched PubMed, BioMed Central, Embase and the Cochrane Central Register of Clinical Trials and references of retrieved articles. Finally, pertinent reviews were also scanned to detect further studies until May 2017. The following inclusion criteria were considered: tracheal intubation in adult critically ill patients; randomized controlled trial; study performed in Intensive Care Unit, Emergency Department or ordinary ward; and work published in the last 20 years...

High-flow nasal oxygen (HFNO) is a potentially life-saving adjunct in the emergency management of the obstructed airway. HFNO has multiple beneficial applications in critical care and respiratory support, but its use in emergency-obstructed airway management has not been defined. This case report describes spontaneous respiration using intravenous anesthesia and high-flow nasal oxygen to successfully manage acute adult epiglottitis with rapidly progressing airway obstruction. Oxygenation, carbon dioxide levels, and airway patency were maintained, which facilitated endotracheal intubation while the patient was spontaneously breathing during general anesthesia...

BACKGROUND: Whilst research demonstrates the benefits of nasal high flow oxygen in the intensive care setting, limited literature exists on its benefits in ward patients. OBJECTIVES: This study evaluated the use of nasal high flow oxygen in adult ward patients with respiratory failure or at risk of respiratory deterioration. Primary outcome was an improvement in pulmonary function as indicated by decreases in respiratory and heart rates and an increase in arterial oxygen saturation via pulse oximetry...

BACKGROUND: Conflicting recommendations exist on whether high-flow nasal cannula (HFNC) oxygen therapy should be administered to adult patients in critical care with acute hypoxemic respiratory failure. We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate its effect on intubation rates. METHODS: We searched electronic databases from inception to April 2016. We included RCTs that compared HFNC oxygen therapy with usual care (conventional oxygen therapy or noninvasive ventilation) in adults with acute hypoxemic respiratory failure...

Importance: High-flow conditioned oxygen therapy delivered through nasal cannulae and noninvasive mechanical ventilation (NIV) may reduce the need for reintubation. Among the advantages of high-flow oxygen therapy are comfort, availability, lower costs, and additional physiopathological mechanisms. Objective: To test if high-flow conditioned oxygen therapy is noninferior to NIV for preventing postextubation respiratory failure and reintubation in patients at high risk of reintubation...

BACKGROUND: Peripheral arterial disease (PAD) of the lower limb is common, with prevalence of both symptomatic and asymptomatic disease estimated at 13% in the over 50 age group. Symptomatic PAD affects about 5% of individuals in Western populations between the ages of 55 and 74 years. The most common initial symptom of PAD is muscle pain on exercise that is relieved by rest and is attributed to reduced lower limb blood flow due to atherosclerotic disease (intermittent claudication). The ankle brachial index (ABI) is widely used by a variety of healthcare professionals, including specialist nurses, physicians, surgeons and podiatrists working in primary and secondary care settings, to assess signs and symptoms of PAD...

Non-invasive ventilation (NIV) is a well recognised and increasingly prevalent intervention in the paediatric critical care setting. In the acute setting NIV is used to provide respiratory support in a flexible manner that avoids a requirement for endotracheal intubation or tracheostomy, with the aim of avoiding the complications of invasive ventilation. This article will explore the physiological benefits, complications and epidemiology of the different modes of NIV including continuous positive airway pressure (CPAP), non-invasive positive pressure ventilation (NIPPV) and high-flow nasal cannula oxygen (HFNC)...

IMPORTANCE: Studies of mechanically ventilated critically ill patients that combine populations that are at high and low risk for reintubation suggest that conditioned high-flow nasal cannula oxygen therapy after extubation improves oxygenation compared with conventional oxygen therapy. However, conclusive data about reintubation are lacking. OBJECTIVE: To determine whether high-flow nasal cannula oxygen therapy is superior to conventional oxygen therapy for preventing reintubation in mechanically ventilated patients at low risk for reintubation...

Use of high-flow oxygen via nasal cannula (HFO2-NC) is increasingly common in intensive care unit (ICU) settings. Despite the critical interface between respiration and swallowing, and the high acuity of patients in ICUs, the impact of HFO2-NC on feeding and swallowing is unknown. The present prospective, single-center, cohort study investigated the impact of HFO2-NC use on oral alimentation in neonatal and adult ICU patients. Oral alimentation status was evaluated in 100 consecutive ICU inpatients (50 neonatal and 50 adult) requiring HFO2-NC...

RATIONALE: Hypoxemia is common during endotracheal intubation of critically ill patients and may predispose to cardiac arrest and death. Administration of supplemental oxygen during laryngoscopy (apneic oxygenation) may prevent hypoxemia. OBJECTIVES: To determine if apneic oxygenation increases the lowest arterial oxygen saturation experienced by patients undergoing endotracheal intubation in the intensive care unit. METHODS: This was a randomized, open-label, pragmatic trial in which 150 adults undergoing endotracheal intubation in a medical intensive care unit were randomized to receive 15 L/min of 100% oxygen via high-flow nasal cannula during laryngoscopy (apneic oxygenation) or no supplemental oxygen during laryngoscopy (usual care)...

BACKGROUND: Physiotherapy in intensive care units (ICU) has traditionally focussed on the respiratory management of mechanically ventilated patients. Gradually, focus has shifted to include rehabilitation in adult ICUs, though evidence of a similar shift in the paediatric ICU (PICU) is limited. OBJECTIVES: Review the evidence to determine the role of physiotherapists in the management of mechanically ventilated patients in PICU. DATA SOURCES: A search was conducted of: PEDro, CINAHL, Medline, PubMed and the Cochrane Library...

Microcirculatory changes and coagulation disturbances are thought to play a key role in sepsis. Some evidence suggests that the percentage of reticulated platelets (RP%) may be a valuable and cost-effective sepsis screening parameter. This was a prospective study in surgical patients to investigate the potential value of RP% as a predictor of mortality in septic shock patients.This was a prospective study conducted in a surgical critical care center of a Chinese tertiary care hospital. Consecutive septic shock patients were enrolled at admission...

Intensive care unit patients who developed systemic inflammatory response syndrome (SIRS) with proven microbial etiology were assigned to the infectious causes (n = 29), while patients with negative cultures and more probable other etiology were assigned to the noninfectious causes (n = 37). Flow cytometry was used to detect the presence of CD64 on neutrophils. The multivariate analysis revealed that KPC-producing Klebsiella pneumoniae rectal colonization and >1.39 mean fluorescence intensity (MFI) of CD64 expression on neutrophils upon day 1 of SIRS were significantly associated with an infectious SIRS...

INTRODUCTION: Mixed phenotype acute leukemia (MPAL) is a rare subset of acute leukemia where the blasts exhibit lineage specific antigens of more than one lineage. Flow cytometric immunophenotyping is essential for the diagnosis of MPAL and the accurate diagnosis highly depends on the panel of markers used. The precise incidence of MPAL is uncertain as various institutions use different combinations of antibodies to assign the blasts to a particular lineage. AIM: The aim was to study the immunoprofile of acute leukemia including aberrant antigen expressions and to study the incidence, clinical features, laboratory findings, and immunophenotype of MPAL in our institution...

BACKGROUND AND PURPOSE: Pain assessment in Intensive Care Units (ICU) can be performed based on validated instruments as the Behavioral Pain Scale (BPS). Despite the existence of this clinical score, there is no Brazilian version of it to assess critically ill patients. This study aimed to translate the BPS into Brazilian Portuguese, verify its psychometric properties (reliability, validity, and responsiveness) and the correlation between pain measured and heart rate (HR), blood pressure (BP), Ramsay, and RASS scores...
