Current opinion in critical care
-
The purpose of this review is to examine the current state of the evidence, including several recent systematic reviews and meta-analyses, to determine if proportional modes of ventilation have the potential to hasten weaning from mechanical ventilation for adult critically ill patients, compared to pressure support ventilation (PSV), the current standard of care during the recovery and weaning phases of mechanical ventilation. ⋯ The current state of the evidence suggests that proportional modes may hasten weaning from mechanical ventilation, but larger, multicentre RCTS are needed to confirm these preliminary findings.

ReviewDoes targeted temperature management at 33 °C improve outcome after cardiac arrest?
Following successful resuscitation from cardiac arrest, a complex set of pathophysiologic processes are acutely triggered, leading to substantial morbidity and mortality. Postarrest management remains a major challenge to critical care providers, with few proven therapeutic strategies to improve outcomes. One therapy that has received substantial focus is the intentional lowering of core body temperature for a discrete period of time following resuscitation. In this review, we will discuss the key trials and other evidence surrounding TTM and present opposing arguments, one 'against' the use of postarrest TTM and another 'for' the use of this therapeutic approach. ⋯ There are several arguments for and against the use of TTM targeting 33 °C for alleviating brain injury after cardiac arrest. More studies are on the way that will hopefully provide more robust evidence and hopefully allow for consensus on this important topic.

ReviewIs tranexamic acid appropriate for all patients undergoing high-risk surgery?
Tranexamic acid (TXA), an antifibrinolytic agent, reduces surgical bleeding in a variety of procedures, such as cardiac, orthopedic, abdominal, and urologic surgery, cesarean section, and neurosurgery. However, there are surgical interventions for which its use is not yet widespread, and some caution persists because of concerns regarding thrombotic risk. The purpose of this review is to analyze the most recent evidence in various subgroups of surgical specialties and the association of TXA with thrombotic events and other side effects (e.g. seizures). ⋯ Wider use of TXA has the potential to improve surgical safety, avoid unnecessary blood use, and save healthcare funds.

ReviewManual mastery vs. mechanized magic: current opinions on manual vs. mechanical chest compressions.
Mechanical chest compression devices are increasingly deployed during cardiopulmonary resuscitation. We discuss the data supporting the use of mechanical chest compression devices during cardiac arrest and provide an opinion about the future of the technology. ⋯ Mechanical chest compression devices offer a solution to some of the human limiting factors of resuscitation, but have failed to demonstrate meaningful improvement in outcomes from cardiac arrest. Routine use of mechanical chest compression devices during cardiac arrest is not supported by evidence.

ReviewCardiac arrest and microcirculatory dysfunction: a narrative review.
This review provides an overview of the role of microcirculation in cardiac arrest and postcardiac arrest syndrome through handheld intravital microscopy and biomarkers. It highlights the importance of microcirculatory dysfunction in postcardiac arrest outcomes and explores potential therapeutic targets. ⋯ Although research continues to suggest the important role that microcirculation may play in postcardiac arrest syndrome and cardiac arrest outcomes, the existing studies are still limited to draw any definitive conclusions. Further research is needed to better understand microcirculatory changes and their significance to improve cardiac arrest care and outcomes.
