Comorbid burden at ICU admission in COVID-19 compared to sepsis and acute respiratory distress syndrome.
Comorbidities are similarly associated with short-term mortality for COVID-19, acute respiratory distress syndrome (ARDS) and sepsis in intensive care unit (ICU) patients, but their adjusted frequencies at admission are unknown. Thus, we aimed to evaluate the adjusted distribution, reported as odds ratios, of known risk factors (i.e., age, sex and comorbidities) for ICU admission between COVID-19, sepsis and ARDS patients in this nationwide registry-based study. ⋯ Patients admitted to ICU with sepsis or ARDS carry a heavier burden of comorbidity and high age than patients admitted with COVID-19. This is likely caused by a combination of: (1) respiratory failure in COVID-19 being less dependent on comorbidities than in other forms of ARDS, and the cause of critical illness in other infections causing sepsis and (2) COVID-19 patients being deferred admission in situations where patients with the other syndromes were admitted.

Somatosensory evoked potentials (SEPs) are highly specific predictors of poor prognosis in hypoxic-ischemic coma when cortical responses (N20s) are absent. However, bilateral N20 presence is nonspecific for good outcomes. High-frequency oscillations (HFOs) in the SEP waveform predict neurologic recovery in animals, but clinical applications are poorly understood. We sought to develop a clinical measure of HFOs to potentially improve detection of good outcomes in coma. ⋯ In this pilot investigation, we developed a novel clinical measure of SEP HFOs. Incorporation of this measure may improve the specificity of the SEP to predict in-hospital GCS outcomes in coma, but requires further validation in specific neurologic injuries and with longitudinal outcomes.

Emergency Anesthesiology Encounters, Care Practices, and Outcomes for Patients with Firearm Injuries: A 9-Year Single-Center US Level 1 Trauma Experience.
Firearm injuries cause significant morbidity and mortality. Patients with firearm injuries require urgent/emergency operative procedures but the literature incompletely describes how anesthesia care and outcomes differ between high acuity trauma patients with and without firearm injuries. Our objective was to examine anesthesia care, resource utilization, and outcomes of patients with acute firearm injuries compared to nonfirearm injuries. ⋯ Over the study period, anesthesiologists increasingly cared for patients with firearm injuries, who often present outside of daytime hours and require urgent operative intervention. Operating room readiness and high-intensity resuscitation capacity, such as access to hemostatic control measures, are critical to achieving intraoperative survival and favorable postoperative outcomes, particularly for patients with firearm injuries.

Hemorrhagic shock (HS) is a life-threatening condition with high mortality rates despite current treatments. This study investigated whether targeted temperature management (TTM) could improve outcomes by modulating inflammation and protecting organs following HS. Using a rat model of HS, TTM was applied at 33 °C and 36 °C after fluid resuscitation. ⋯ Cytokine array analysis confirmed reduced levels of proinflammatory cytokines with TTM at 36 °C. These results collectively highlight the potential of TTM at 36 °C as a therapeutic approach to improve outcomes in HS. By addressing multiple aspects of injury and inflammation, including modulation of macrophage responses and cytokine profiles, TTM at 36 °C offers promising implications for critical care management after HS, potentially reducing mortality and improving patient recovery.
