Comparative Study Observational StudyPrognostic evaluation of severe sepsis and septic shock: Procalcitonin clearance vs Δ Sequential Organ Failure Assessment.
The purpose of the study is to compare the clearance of procalcitonin (PCT-c) in the first 24 and 48 hours of treatment of severe sepsis and septic shock with another early prognostic marker represented by the 48-hour Δ Sequential Organ Failure Assessment (SOFA). ⋯ The 48-hour Δ SOFA score and the clearance of 24- and 48-hour PCT are useful markers of prognosis in patients with severe sepsis and septic shock. A decrease in PCT-c in the first 24 hours of treatment should prompt the reassessment of the appropriateness and adequacy of treatment.

Prolonged mechanical ventilation in Canadian intensive care units: A national survey.
We sought to describe prevalence and care practices for patients experiencing prolonged mechanical ventilation (PMV), defined as ventilation for 21 or more consecutive days and medical stability. ⋯ Prolonged mechanical ventilation patients occupied 11% of Canadian acute care ventilator bed capacity. Most units preferred an individualized approach to weaning and mobilization with considerable variation in weaning methods, protocol availability, access to specialized rehabilitation equipment, communication technology, psychiatry, and discharge follow-up.

Observational StudyComparative effectiveness of physician diagnosis and guideline definitions in identifying sepsis patients in the emergency department.
The purpose of our study was to compare the agreement of emergency physician diagnoses relative to the 1991 American College of Chest Physicians (ACCP)/Society of Critical Care Medicine (SCCM) and 2001 ACCP/SCCM/European Society of Intensive Care Medicine/American Thoracic Society/Surgical Infection Society internationally accepted definitions of sepsis, severe sepsis, and septic shock. ⋯ Our study showed that ED physician diagnosis of sepsis may disagree with the international definitions such that severe sepsis is underrecognized by clinical judgment alone. Although these results are limited to a single center, we raise concern that early treatments for these high-risk patients may be delayed due to inaccurate clinical diagnosis. Efforts are needed to increase the application of sepsis guideline definitions to better identify ED patients with this potentially deadly condition.

Comparative StudyComparison between ultrasound- and bronchoscopy-guided percutaneous dilational tracheostomy in critically ill patients: A retrospective cohort study.
Percutaneous dilational tracheostomy (PDT) is routinely performed in the intensive care unit with bronchoscopic guidance. Recently, ultrasound (US) has emerged as a new safety adjunct tool to increase the efficacy of PDT. However, the available data are limited to case series without any control group. Hence, a retrospective cohort study was designed to evaluate the efficacy of US-guided PDT compared with bronchoscopy-guided PDT. ⋯ Ultrasound-guided PDT is effective, safe, and associated with similar complication rates and clinical outcomes compared with bronchoscopy-guided PDT.

Low-dose recombinant factor VIIa for reversing coagulopathy in patients with isolated traumatic brain injury.
The purpose of this study was to investigate the role of low-dose recombinant factor VIIa (rFVIIa) (20 μg/kg) in reversing coagulopathy in patients with isolated traumatic brain injury (TBI). ⋯ The use of low-dose rFVIIa (20 μg/kg) is effective for correcting coagulopathy in patients with TBI without an increase in thromboembolic events. Moreover, it is more effective for preventing the occurrence of PHI.
