Case ReportsUsing Compressed Virtual Reality Exposure Therapy for an Adult Critical Illness Survivor: A Case Report.
Nearly one-quarter of adult critical illness survivors develop posttraumatic stress disorder symptoms triggered by sensory stimuli after intensive care unit discharge. Intensive care unit delirium is a risk factor for posttraumatic stress disorder. Compressed virtual reality exposure therapy (C-VRET) incorporates sensory stimuli to reduce posttraumatic stress disorder symptoms through habituation. ⋯ This report highlights the severity of posttraumatic stress disorder symptoms in critical illness survivors and the importance of strategies to limit delirium and posttraumatic stress disorder. Compressed virtual reality exposure therapy may reduce posttraumatic stress disorder symptoms in critical illness survivors.

Background : Previous preclinical studies have demonstrated a pathobiome after traumatic injury; however, the impact of postinjury sepsis on gut epithelial permeability and bacterial translocation remains unknown. We hypothesized that polytrauma with postinjury pneumonia would result in impaired gut permeability leading to specific blood microbiome arrays. Methods : Male and proestrus female Sprague-Dawley rats were subjected to either polytrauma (PT), PT plus 2-hours daily chronic restraint stress (PT/CS), PT with postinjury day 1 inoculation with pseudomonas pneumonia (PT + PNA), PT/CS + PNA, or naive controls. ⋯ Females PT/CS + PNA had a significant abundance of Staphylococcus at day 2 and Streptococcus at day 7 in the blood biome compared to male counterparts ( P < 0.05). Conclusion : Multicompartmental trauma with postinjury pneumonia results in increased intestinal permeability and bacteremia with a unique blood biome, with sexual dimorphisms evident in the blood biome composition. These findings suggest that postinjury sepsis has clinical significance and could influence outcomes after severe trauma and critical illness.

Acute kidney injury (AKI) is a frequent and serious complication in critically ill patients. Currently, no effective therapy to prevent or treat AKI is available. This review highlights recently published developments on pharmacological treatments that aim to prevent AKI or to alleviate the severity of AKI in critical ill patients. ⋯ The discovery of reno-protective therapies is hampered by the timely detection and recognition of the overriding mechanism of AKI. Nevertheless, several compounds are under investigation, which hold promise for a future treatment.

Acute kidney injury (AKI) is commonly encountered in critical care medicine as is intravenous fluid therapy. It is accepted that there is interplay between fluid use and AKI, both potentially positive and negative. An understanding of the physiological rationale for fluid is important to help clinicians when considering fluid therapy in patients with, or at risk for AKI; this includes understanding choice of fluid, method of monitoring, administration and clinical sequelae. ⋯ This review assesses the physiological rationale for fluid use in ICU cohorts with AKI of various types, as well as a systematic approach for choice of fluid therapy using a number of different variables, which aims to help guide clinicians in managing fluid use and fluid balance in critically ill patients with AKI.

Echocardiographic Findings in Critically Ill COVID-19 Patients Treated With and Without Extracorporeal Membrane Oxygenation.
To describe echocardiographic findings among mechanically ventilated patients with COVID-19 acute respiratory distress syndrome, comparing those with and without venovenous extracorporeal membrane oxygenation (VV ECMO) support. ⋯ The prevalence of echocardiographic abnormalities, in particular RV dysfunction, was frequent among patients with COVID-19 receiving VV ECMO support and was associated with worse clinical outcomes.
