- Acute respiratory failure is one of the most common problems encountered in intensive care units (ICU) and mechanical ventilation is the mainstay of supportive therapy for such patients. A mismatch between ventilator delivery and patient demand is referred to as patient-ventilator asynchrony (PVA). An important hurdle in addressing PVA is the lack of a reliable framework for continuously and automatically monitoring the patient and detecting various types of PVA. ⋯ - The pilot study establishes the feasibility of using a machine learning framework to provide waveform analysis equivalent to an expert human.

Single-Center Experience With Venovenous ECMO for Influenza-Related ARDS.
This study was designed to determine whether venovenous extracorporeal membrane oxygenation (VV ECMO) reduced mortality in patients with influenza-related acute respiratory distress syndrome (ARDS). ⋯ Influenza-related ARDS has a high mortality rate and patients treated only with mechanical ventilation have worse outcome than those managed with VV ECMO. More liberal use of ECMO should be considered in patients with influenza-related ARDS.

Serial Diaphragm Ultrasonography to Predict Successful Discontinuation of Mechanical Ventilation.
Diaphragm excursion and contraction velocity measured using ultrasonography have been used to assess diaphragm function. We aimed to evaluate the performance of diaphragm ultrasonography during weaning from mechanical ventilation (MV). ⋯ Diaphragm excursion measured during SBT is an imperfect predictor of the outcome of extubation. Maintenance of diaphragm excursion between A/C and SBT has good performance characteristics by AUC analysis. Diaphragm contraction velocity has poor ability to predict outcome of extubation.

Early-onset pneumonia (EOP) after endotracheal intubation is common among critically ill patients with a neurologic injury and is associated with worse clinical outcomes. ⋯ The administration of a single antibiotic dose following intubation may reduce the incidence of microbiologically confirmed EOP in patients with neurologic injury who are intubated ≥ 72 h. A prophylaxis strategy does not appear to increase the rate of virulent organism growth or the rate of late-onset pneumonia. However, this practice is not associated with a decrease in days of antibiotic use in the ICU or any clinical outcomes benefit.

Selective Serotonin Reuptake Inhibitors and Serotonin-Norepinephrine Reuptake Inhibitors Are Not Associated With Bleeding or Transfusion in Cardiac Surgical Patients.
Selective serotonin reuptake inhibitor (SSRI) and serotonin-norepinephrine reuptake inhibitor (SNRI) use is known to alter platelet activation and aggregation leading to impairment in hemostasis. Previous studies are ambiguous with regard to bleeding, transfusion, and perioperative complications in patients undergoing cardiac surgery. The purpose of this study was to evaluate the risk of perioperative bleeding, transfusion, morbidity, and mortality in cardiac surgical patients taking SSRI/SNRIs compared with propensity-matched controls. ⋯ SSRI/SNRI use was not associated with an increased risk of bleeding or transfusion in patients undergoing cardiac surgery. While there was prolonged mechanical ventilation and increased ICU/hospital LOS in the SSRI/SNRI group, it is unclear that this finding is the result of such medications or rather associated with the underlying psychiatric condition for which they are prescribed. The results of this study suggest that perioperative interruption of SSRI/SNRIs to reduce the risk of perioperative bleeding and transfusion is unwarranted and may risk destabilization of patients' psychiatric condition.
