Sepsis and septic shock are prevalent conditions that are likely to increase in prevalence in the future. Given the high mortality and morbidity associated with sepsis and sepsis-induced cardiac dysfunction, we must continue to make advances in knowledge of the complex physiologic interactions and how we may target specific mediators for potential therapeutic options in the future. ⋯ Sepsis-induced cardiomyopathy is the result of complicated interactions between the pathogen, the body's response to infection, and iatrogenic injury. Interplay between inflammatory, metabolic, and adrenergic systems results in direct and indirect myocardial injury leading to decreases in both systolic and diastolic cardiac function. As the interactions are further elucidated with additional research into other proteins and mediators, new treatment options can be researched. VIDEO ABSTRACT.

ReviewNutrition in the ICU: new trends versus old-fashioned standard enteral feeding?
The narrative review aims to summarize the relevant studies from the last 2 years and provide contextual information to understand findings. ⋯ Studies from the last 2 years will have marked impact on future nutritional support strategies and practice guidelines for critical care nutrition as they challenge several old-fashioned concepts.

ReviewThe ethics of interventional procedures for patients too ill for surgery.
Minimally invasive interventional procedures are increasingly popular options for patients who are high-risk candidates for open surgical procedures. It is unclear how to proceed in the rare circumstance of a complication during an interventional procedure, where addressing the complication would require exposing the patient to the full risk that was being avoided with the minimally invasive technique. This review provides recommendations on how to approach this paradoxical scenario. ⋯ Interventional procedures, and emergent open surgery, should be offered as long as patients are fully informed about the benefits and risks, including the implications of potential life-sustaining treatments, and whether their respective goals of treatment are consistent with the intervention. Implementing this framework will require a cultural shift in physician attitudes to recognize that in some cases, nonintervention or less aggressive treatment may be a reasonable alternative to surgical intervention.

Trauma is the most common cause of pediatric mortality. Much of the research that led to life-saving interventions in adults, however, has not been replicated in the pediatric population. Children have important physiologic and anatomic differences from adults, which impact hemostasis and transfusion. Hemorrhage is a leading cause of death in trauma, and children have important differences in their coagulation profiles. Transfusion strategies, including the massive transfusion protocol and use of antifibrinolytics, are still controversial. In addition to the blood that is lost from the injury itself, trauma leads to inflammation and to a dysfunction in hemostasis, causing coagulopathy. ⋯ This article explores new research from the past year in pediatric trauma, starting with the physiologic differences in pediatric red blood cells and coagulation profiles. We also looked at the dramatic change in thinking over the past decade in the tolerable level of anemia in critically ill pediatric patients, as well as scales for determining the need for massive transfusion and exploring if the concepts of damage control resuscitation apply to children. Other strategies, such as avoiding hypothermia, and the selective administration of antifibriniolytics, are important in pediatric trauma as well. Future research that is pediatric focused is needed for the optimal care of our youngest patients.

ReviewBlood transfusion management in the severely bleeding military patient.
Hemorrhage remains the primary cause of preventable death on the battlefield and in civilian trauma. Hemorrhage control is multifactorial and starts with point-of-injury care. Surgical hemorrhage control and time from injury to surgery is paramount; however, interventions in the prehospital environment and perioperative period affect outcomes. The purpose of this review is to understand concepts and strategies for successful management of the bleeding military patient. Understanding the life-threatening nature of coagulopathy of trauma and implementing strategies aimed at full spectrum hemorrhage management from point of injury to postoperative care will result in improved outcomes in patients with life-threatening bleeding. ⋯ Lessons learned in the treatment of combat casualties will likely continue to have positive impact and influence and the management of hemorrhage in the civilian trauma setting.
