Terapia intensiva

OBJECTIVE: To develop a simple, robust, safe and efficient invasive mechanical ventilator that can be used in remote areas of the world or war zones where the practical utility of more sophisticated equipment is limited by considerations of maintainability, availability of parts, transportation and/or cost. METHODS: The device implements the pressure-controlled continuous mandatory ventilation mode, complemented by a simple assist-control mode. Continuous positive airway pressure is also possible...

OBJECTIVE: To evaluate whether critical SARS-CoV-2 infection is more frequently associated with signs of corticospinal tract dysfunction and other neurological signs, symptoms, and syndromes, than other infectious pathogens. METHODS: This was a prospective cohort study with consecutive inclusion of patients admitted to intensive care units due to primary infectious acute respiratory distress syndrome requiring invasive mechanical ventilation > 48 hours. Eligible patients were randomly assigned to three investigators for clinical evaluation, which encompassed the examination of signs of corticospinal tract dysfunction...

OBJECTIVE: To compare the lung mechanics and outcomes between COVID-19-associated acute respiratory distress syndrome and non-COVID-19-associated acute respiratory distress syndrome. METHODS: We combined data from two randomized trials in acute respiratory distress syndrome, one including only COVID-19 patients and the other including only patients without COVID-19, to determine whether COVID-19-associated acute respiratory distress syndrome is associated with higher 28-day mortality than non-COVID-19 acute respiratory distress syndrome and to examine the differences in lung mechanics between these two types of acute respiratory distress syndrome...

OBJECTIVE: To evaluate the effectiveness of the Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ solution in activating the rapid response team in a timely manner compared to manual activation. METHODS: The Hillrom study is a single-center, open-label, superiority, cluster-randomized, parallel-group (1:1 allocation ratio) clinical trial that will be conducted in a tertiary hospital. Two sets of three wards with 28 beds will be included (one as the intervention cluster and the other as the control)...

OBJECTIVE: To synthesize the evidence about diagnostic accuracy of inferior vena cava collapsibility (IVCc) in prediction of fluid responsiveness among spontaneously breathing patients. DESIGN: Systematic review of diagnostic accuracy studies. SETTING: Intensive care units or emergency departments. PATIENTS AND PARTICIPANTS: spontaneously breathing patients with indication for fluid bolus administration. INTERVENTIONS: A search was conducted in MEDLINE and EMBASE...

OBJECTIVE: To describe the implementation and results of the collaborative PROADI-SUS project by the Brazilian Ministry of Health to reduce healthcare-associated infections: ventilator-associated pneumonia, primary central line-associated bloodstream infection and catheter-associated urinary tract infections. METHODS: This was a prospective observational study that investigated the implementation stages and outcomes during 18 months in five intensive care units in the city of Recife...

OBJECTIVE: Exploring infectious diseases (ID) practice in Intensive Care Unit (ICU) to identify gaps and opportunities. DESIGN: Online international survey (PRACT-INF-ICU) endorsed by the ESICM and open from July 30, 2019 to October 19, 2019. SETTING: International study conducted in 78 countries. PARTICIPANTS: Physicians working in ICU. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Practice variations were assessed according to respondents' countries income class, training, and years of practice...

INTRODUCTION: Diarrhea is a frequent complication in critically ill patients. Its origin is multifactorial. The objective of this work is to analyze the relationship between 5 ready-to-use formulas and the development of diarrhea in critically ill patients. METHODS: Retrospective study where the volume of the stools of 315 patients and the presence of diarrhea defined with a cut-off point of a volume of 250 ml/day were evaluated. 35.34% of the patients presented diarrhea with said cut-off point...

OBJECTIVE: To investigate the applicability of the Respiratory Rate-Oxygenation Index to identify the risk of high-flow nasal cannula failure in post-extubation pneumonia patients. METHODS: This was a 2-year retrospective observational study conducted in a reference hospital in Bogotá, Colombia. All patients in whom post-extubation high-flow nasal cannula therapy was used as a bridge to extubation were included in the study. The Respiratory Rate-Oxygenation Index was calculated to assess the risk of post-extubation high-flow nasal cannula failure...

OBJECTIVE: To compare the perceptions of patients' relatives with the perceptions of health professionals regarding a flexible visitation model in intensive care units. METHODS: Cross-sectional study. This study was carried out with patients' relatives and members of the care team of a clinical-surgical intensive care unit with a flexible visitation model (12 hours/day) from September to December 2018. The evaluation of the flexible visitation policy was carried out through an open visitation instrument composed of 22 questions divided into three domains (evaluation of family stress, provision of information, and interference in the work of the team)...

The number of elderly patients admitted to cardiac intensive care units (CICU) is significantly increasing. Nowadays, novel diagnostic and therapeutic tools allow to treat the vast majority of cardiac acute diseases, nonetheless care of elderly patients requires a careful clinical evaluation. A favorable proportion of cost-effectiveness is warranted, aimed at avoiding futile procedures or treatments. On the other hand, the availability of minimally invasive procedures carries forward old limits to treatments in elderly patients in CICU...

(1) Background: Vestibular migraine (VM) and Meniere's disease (MD) share multiple features in terms of clinical presentations and auditory-vestibular dysfunctions, e.g., vertigo, hearing loss, and headache. Therefore, differentiation between VM and MD is of great significance. (2) Methods: We retrospectively analyzed the medical records of 110 patients with VM and 110 patients with MD. We at first established a regression equation by using logistic regression analysis. Furthermore, sensitivity, specificity, accuracy, positive predicted value (PV), and negative PV of screened parameters were assessed and intuitively displayed by receiver operating characteristic curve (ROC curve)...

Posterior reversible encephalopathy syndrome is a rare clinical and radiological syndrome characterized by vasogenic edema of the white matter of the occipital and parietal lobes, which are usually symmetrical, resulting from a secondary manifestation of acute dysfunction of the posterior cerebrovascular system. We describe a case of posterior reversible encephalopathy syndrome secondary to SARS-CoV-2 infection in a 9-year-old boy who developed acute hypoxemic respiratory failure and required assisted mechanical ventilation...

Ketamine is unique among anesthetics and analgesics. The drug is a rapid-acting general anesthetic that produces an anesthetic state characterized by profound analgesia, preserved pharyngeal-laryngeal reflexes, normal or slightly enhanced skeletal muscle tone, cardiovascular and respiratory stimulation, and occasionally a transient and minimal respiratory depression. Research has demonstrated the efficacy of its use on anesthesia, pain, palliative care, and intensive care. Recently, it has been used for postoperative and chronic pain, as an adjunct in psychotherapy, as a treatment for depression and posttraumatic stress disorder, as a procedural sedative, and as a treatment for respiratory and/or neurologic clinical conditions...

OBJECTIVE: The central venousarterial carbon dioxide pressure to arterial-central venous oxygen content ratio (Pcv-aCO2/Ca-cvO2) is frequently used as a surrogate for tissue oxygenation. We aimed to identify and synthesize literature and quality of evidence supporting Pcv-aCO2/Ca-cvO2 as a predictor of mortality in critically ill patients compared with lactate. METHODS: We searched several databases for studies measuring Pcv-aCO2/Ca-cvO2 in critically ill patients...
