Meta AnalysisThe predictive value of airway occlusion pressure at 100 msec (P0.1) on successful weaning from mechanical ventilation: A systematic review and meta-analysis.
The predictive value of airway occlusion pressure at 100 milliseconds (P0.1) on weaning outcome has been controversial. We performed a meta-analysis to investigate the predictive value of P0.1 on successful weaning from mechanical ventilation. ⋯ This meta-analysis suggests that P0.1 is a useful tool to predict successful weaning. To determine clinical utility, a large prospective study investigating the sensitivity and specificity of P0.1 on weaning outcomes from mechanical ventilation is warranted.

Meta AnalysisEffectiveness of polymyxin B-immobilized hemoperfusion against sepsis and septic shock: A systematic review and meta-analysis.
To evaluate the efficacy and safety of Polymyxin B-immobilized hemoperfusion (PMX-HP) against sepsis or septic shock. ⋯ Using PMX-HP to treat patients with less severe sepsis can reduce overall mortality and is safe. Treatment efficacy may benefit from the reduction of endotoxin level and the improvement of hemodynamics. More high quality RCTs are required to further evaluate the clinical role of PMX-HP against severe sepsis or septic shock.

ReviewEthical, legal, and communication challenges in managing goals-of-care discussions in chronically critically ill patients.
Clinicians should expect controversial goals of care discussions in the surgical intensive care from time to time. Differing opinions about the likelihood of meaningful recovery in patients with chronic critical illness often exist between intensive care unit providers of different disciplines. ⋯ Providers in the surgical intensive care unit should approach goals-of-care discussions in a structured and interprofessional manner. This best practice paper highlights medical, legal and ethical implications of changing goals of care from prioritizing cure to prioritizing comfort and provides tools that help physicians become effective leaders in the multi-disciplinary management of patients with challenging prognostication.

ReviewDoes stress influence the performance of cardiopulmonary resuscitation? A narrative review of the literature.
Cardiopulmonary resuscitation represents a major physical and psychological challenge for all involved health care workers because survival of the patients is closely related to the timely and accurate actions of rescuers. Consequently, rescuers may experience high levels of acute mental stress. Stress, in turn, may influence attentional resources and distractibility, which may affect the quality of resuscitation. ⋯ Finally, few interventional studies assessed whether interventions aiming at reducing levels of stress may have a beneficial effect on resuscitation performance, but results are variable. Although the mechanisms linking stress to performance of emergency teams are still not fully understood, factors such as individual experience and self-confidence of rescuers, gender composition and hierarchy within resuscitation teams may play an important role. This review provides a targeted overview of how stress can be defined and measured, how it may influence emergency situations such as a cardiopulmonary resuscitation, and which interventions have the potential to reduce overwhelming stress.

Review Meta AnalysisUse of recombinant activated factor VII for the treatment of perioperative bleeding in noncardiac surgery patients without hemophilia: A systematic review and meta-analysis of randomized controlled trials.
To evaluate the efficacy and safety of perioperative use of recombinant activated factor VII (rFVIIa) in noncardiac patients. ⋯ For perioperative hemorrhagic patients, rFVIIa-based hemostatic therapy showed no effect on mortality, ICU or hospital LOS, or the rate of thromboembolic events, although it appears to decrease blood loss and reduce the need for blood product transfusion in a subset of patients.
