Filter by:Some ICU ventilated patients might present with large tidal volume despite very low or inexistant presser support. Patient-Self Inflicted Lung Injury (P-SILI) might appear related with large alveolar stretch an distension. Two clinical presentations are observed: patients with or without respiratory distress signs such as supra-clavicular depression and thoracic-abdominal asynchronies. The aim of this study is to compare the pulmonary physio(-patho)logical parameters of these two types of patients (eupneic or with respiratory distress signs), and presenting important TV in spite of a minimal adjustment of the ventilatory support, except for Acute Respiratory Distress Syndrome (ARDS).
Acute respiratory distress syndrome (ARDS) accounts for almost 10% of intensive care units (ICU) admissions. Three ARDS stages have been defined, based on the PaO2/FIO2 ratio measured with positive end-expiratory pressure (PEEP) ≥5 cmH2O: mild (201-300 mmHg), moderate (200-101 mmHg), and severe (≤100mmHg). They represent 30.0%, 46.6%, and 23.4% of ARDS, respectively. Mechanical invasive ventilation (MV), the cornerstone of ARDS patient care, has a primary goal to protect the lung from ventilator-induced lung injury (VILI). Delivering MV in a prone position (PP) has been shown to improve oxygenation, protect the lung through a better homogenization of lung stress/strain, and stabilize hemodynamics. A meta-analysis of four randomized controlled trials showed beneficial effect of PP vs. supine position (SP) in the most hypoxemic patients. A fifth randomized controlled trial further showed a significant reduction in mortality with PP in ARDS patients with PaO2/FIO2 <150 mmHg, when neuromuscular blockade and long prone positioning sessions were used. Therefore, PP has since been strongly recommended for ARDS patients with PaO2/FIO2 <150 mmHg. Yet, there is limited evidence in patients with mild to moderate ARDS. There are, however, strong arguments supporting the need for a new trial in ARDS patients with PaO2/FIO2 in the range 150-300 mmHg: 1. There is no trial that has specifically tested PP in this ARDS subset; 2. PP is safe and has become a standard of care in ICU; 3. Should VILI prevention be a mechanism through which PP improves survival, this should be involved in all ARDS patients; 4. The mortality at hospital discharge in this subset of ARDS remains significant, amounting to 34.9% (95% confidence intervals 31.4-38.5%) in mild and 40.3% (37.4-43.3) in moderate stages; 5. Among 580 patients with mild ARDS at admission to the ICU, in-hospital mortality was 10%, 30%, and 37% for those who improved, persisted, and worsened ARDS, respectively. 6. Finally, PP has been shown to be cost-effective under commonly accepted thresholds. The hypothesis is that in patients within the 150-300mmHg PaO2/FIO2 range at the time of ARDS diagnosis, PP can reduce mortality as compared to a similar group left in the SP.
Background: For patients with out-of-hospital cardiac arrest (OHCA) at the intensive care unit (ICU), oxygen therapy plays an important role in post resuscitation care. During hospitalisation, a lot of these patients occur with pulmonary arterial hypertension (PAH). Currently a wide oxygen target is recommended but no evidence regarding optimal treatment targets to minimise the prevalence of PAH exists. Methods: The RELIEPH trial is a substudy within the BOX (Blood pressure and OXygenation targets in post resuscitation care) trial. It is a single-center, parallel-group randomised controlled clinical trial. 300 patients with OHCA hospitalised at the ICU are allocated to one of the two oxygenation interventions, either a restrictive- (9-10 kPa) or liberal (13-14 kPa) oxygen target both within the recommended range. The primary outcome is the fraction of time with pulmonary hypertension (mPAP >25 mmHg) out of total time with mechanical ventilation. Secondary outcomes are: length of ICU stay among survivors, lactate clearance, right ventricular failure, 30 days mortality and plasma brain natriuretic peptide (BNP) level 48 hours from randomisation. Discussion: This study hypothesises that a liberal target of oxygen reduces the time with PAH during mechanical ventilation compared to a restrictive oxygen target in patients with OHCA at the ICU. When completed, this study hopes to provide new knowledge regarding which oxygen target is beneficial for this group of patients.
The gender, age, ICU diagnosis, basic diseases, antibiotic treatment plan, physiological indicators, duration of hospital stay, length of stay in ICU, hospitalization cost, prognosis and other discharge information of patients receiving tigecycline or polymyxin B admitted to the ICU of four provincial-level Grade A hospitals in Changsha, Hunan Province ,China from 2017 to 2021 were included. To analyze the therapeutic effect of tigecycline-based or polymyxin B-based antibiotic regimens and their effect on the prognosis of patients, and to conduct subgroup analysis.
Through clinical cases or retrospective work with small sample size, some authors have observed an improvement in hemodynamic parameters, with a reduction or even withdrawal of norepinephrine after administration of a single dose of hydroxocobolamin (HCB) in refractory vasoplegic shock (cardiac surgery, liver transplantation and septic shock). HCB produces beneficial alterations in NO metabolism and may be suitable in vasoplegic syndrome. In addition, HCB seems to be involved in the elimination of hydrogen sulfide which also has an endogenous vasodilator function in the vascular endothelium. By these different actions it would cause vasoconstriction in vascular smooth muscle cells. Previous reports demonstrate that HCB was useful for refractory vasoplegic syndrome. The investigators will conduct a retrospective data collection of patients who was given intravenous HCB for refractory vasoplegic shock since January 2019.

Hospital-acquired bloodstream infection (BSI) is serious care problem worldwide associated with significant morbidity and mortality. However, only few nationwide studies have focused on the incidence of BSI, and its results were often inconsistent. The objective of this study was to analyze bloodstream infections in patients hospitalized in the intensive care unit of the tertiary, university hospital. Special attention was put on the etiology of the infections, the antimicrobial susceptibility/resistance of the isolated pathogens, as well as the incidence of central vein catheters infections in the analyzed population. Data were collected in the intensive care unit of the Military Institute of Medicine, Warsaw, Poland, between January, 1, 2007 and December, 31, 2019.
A randomized controlled trial is designed to investigate the safety and clinical efficacy of a mega dose of VD in patients admitted in intensive care unit (ICU). Patients will be randomly allocated to receive 400,000 IU of VD3 or placebo. They will be followed up until ICU discharge or death or the 15th day of ICU stay. Adverse events that occur during ICU stay is collected. Primary outcome is intensive care unit-acquired infection (ICU-AI), and secondary outcomes are septic shock, organ failure, and ICU-mortality. Plasma 25-hydroxyvitamin D is assessed at baseline and at the end of follow-up. Cox regression models will be applied to test how VD supplementation affects adverse outcomes while adjusting for confounders.
After cardiopulmonary bypass heart surgery, with the rewarming of body temperature, the metabolic capacity of the body is enhanced, the microcirculation is opened, and tissue perfusion is increased. At the same time, the body pays off the oxygen debt formed by the low temperature and reduced blood flow in cardiopulmonary bypass, so that the tissue oxygen demand increases and oxygen consumption increases.Analgesia and sedation are important treatment measures for patients after cardiopulmonary bypass. S-isomer of ketamine and eselamine enhanced the sedation and enhanced the analgesic effect, but whether it can improve the imbalance of oxygen supply and oxygen consumption after cardiopulmonary bypass is unknown.
Delirium is common in septic patients, especially those receiving mechanical ventilation in the intensive care unit (ICU). Dexmedetomidine is a highly selective α2 adrenoreceptor agonist with anxiolytic, sedative, analgesic, and anti-inflammatory effects. Use of dexmedetomidine in mechanically ventilated ICU patients is associated with less delirium and improved outcomes. However, dexmedetomidine infusion produces dose-dependent bradycardia and hypotension; these limited the use of dexmedetomidine in ICU patients. This study is designed to test the hypothesis that low-dose dexmedetomidine infusion can also reduce delirium in mechanically ventilated ICU patients with sepsis.
