Observational StudyFull Finger Reperfusion Time Measured by Pulse Oximeter Waveform Analysis in Children.
Capillary refill time is a noninvasive method to assess tissue perfusion to determine shock status. Capillary refill time is defined as the time required to regain skin color after blanching pressure is applied. Although common methods to measure capillary refill time depend on clinicians' visual assessment, a new approach using a pulse oximeter waveform analysis exists, referred to as full finger reperfusion time. We aim to evaluate reproducibility and validity of the novel full finger reperfusion time measurement using clinicians' visual capillary refill time assessment as a reference standard. ⋯ Full finger reperfusion time demonstrated good reproducibility. Full finger reperfusion time showed moderate correlation with clinician capillary refill time. Full finger reperfusion time was 1.14 seconds longer than capillary refill time. Future studies should focus on the clinical value of full finger reperfusion time as a monitoring device for hemodynamics in critically ill children.

Multicenter Study Observational StudyNormothermia in Patients With Sepsis Who Present to Emergency Departments Is Associated With Low Compliance With Sepsis Bundles and Increased In-Hospital Mortality Rate.
To investigate the impact of normothermia on compliance with sepsis bundles and in-hospital mortality in patients with sepsis who present to emergency departments. ⋯ Normothermia at emergency department triage was significantly associated with an increased risk of in-hospital mortality and a lower rate of compliance with the sepsis bundle. Despite several limitations, our findings suggest a need for new strategies to improve sepsis outcomes in this group of patients.

Multicenter StudyEarly Arterial Embolization and Mortality in Mechanically Ventilated Patients With Hemoptysis: A Nationwide Retrospective Cohort Study.
Hemoptysis, a symptom common across various respiratory diseases, can cause airway obstruction leading to a life-threatening condition. Arterial embolization has been used to control bleeding from the lower airways. However, limited studies have evaluated its effects on in-hospital mortality in patients with hemoptysis requiring mechanical ventilation. The objective of this study was to clarify whether early intervention by arterial embolization reduced mortality in mechanically ventilated patients with hemoptysis. ⋯ Our results show that early intervention by arterial embolization may be effective in reducing 7-day and 30-day mortalities in patients with life-threatening hemoptysis requiring mechanical ventilation.

Modifiable Risk Factors and Mortality From Ischemic and Hemorrhagic Strokes in Patients Receiving Venoarterial Extracorporeal Membrane Oxygenation: Results From the Extracorporeal Life Support Organization Registry.
Although acute brain injury is common in patients receiving extracorporeal membrane oxygenation, little is known regarding the mechanism and predictors of ischemic and hemorrhagic stroke. We aimed to determine the risk factors and outcomes of each ischemic and hemorrhagic stroke in patients with venoarterial extracorporeal membrane oxygenation support. ⋯ Despite a decrease in the prevalence of acute brain injury in recent years, mortality rates remain high when ischemic and hemorrhagic strokes are present. Future research is necessary on understanding the timing of associated risk factors to promote prevention and management strategy.

Multicenter StudyExtracorporeal Membrane Oxygenation to Support Life-Threatening Drug-Refractory Electrical Storm.
Despite rapid implementation of anti-arrhythmic treatment and sedation and controlling the triggering event, rare patients develop treatment-refractory electrical storm and their hemodynamic instability prevents emergency catheter ablation. In that context, venoarterial extracorporeal membrane oxygenation could rapidly restore hemodynamics and tissue perfusion and reduce myocardial oxygen consumption, until adequate anti-arrhythmic drug levels are reached to safely perform catheter ablation. ⋯ Among venoarterial extracorporeal membrane oxygenation-supported drug-refractory electrical storm patients, 42% survived 6 months post-ICU admission. Ventricular tachycardia and/or ventricular fibrillation episodes alternating with short periods of sinus rhythm and age less than 50 years were independently associated with better survival.
