Although there have been numerous advancements in burn wound management, burn injuries are still a major cause of morbidity and mortality in the United States, and novel therapeutics are still needed to improve outcomes. Poloxamer 188 (P188) is a synthetic copolymer with Food and Drug Administration (FDA) approval that has many biological applications. This study aimed to review the literature on P188 in burn injuries and its effects based on burn mechanisms. ⋯ Although its utility may be limited in radiation injuries, P188 may be helpful in delaying the initial damage caused by radiation burns. P188 therefore has the potential to be used as a therapy in both burn wound management and in the treatment of systemic injuries sustained through burns. Future studies should aim to assess the efficacy of P188 in clinical models of burn injury.

The literature has revealed gaps in knowledge and attitudes regarding pediatric pain management among Ghanaian nurses and nursing students that can be attributed to inadequate education in the area. Consequently, nursing tutors teaching pain management might not have the appropriate knowledge to transfer to their students. ⋯ Educating nursing tutors about pediatric pain is imperative to enable students and thus future nurses to be equipped with the necessary evidence-based knowledge of how to manage pediatric pain.

Septic cardiomyopathy is a common complication in patients with sepsis, and is one of the indicators of poor prognosis. Its pathogenesis is complex, involving calcium ion imbalance in cardiomyocytes, nitric oxide (NO) synthesis disorder, mitochondrial abnormalities and immune inflammatory reaction, especially mitochondrial abnormalities. In this paper, the mechanism of mitochondrial abnormalities causing septic cardiomyopathy was discussed from the aspects of mitochondrial structure change, mitochondrial energy metabolism disorder, redox imbalance, mitochondrial calcium overload, mitochondrial biosynthesis and autophagy abnormalities.

Postoperative pulmonary complications can increase hospital length of stay, postoperative morbidity, and mortality. Although many factors can increase the risk of postoperative pulmonary complications, it is not known whether intraoperative ventilation/perfusion (V/Q) mismatch can be associated with an increased risk of postoperative pulmonary complications after major noncardiac surgery. ⋯ In patients with intermediate or high risk of postoperative pulmonary complications undergoing major noncardiac surgery, intraoperative V/Q mismatch is associated with the development of postoperative pulmonary complications. Increased high V/Q ratio before extubation is independently associated with the occurrence of postoperative pulmonary complications in the first 7 days after surgery.

Observational StudyValidation of a Novel Method for Noninvasive Mixed Venous Oxygen Saturation Monitoring in Anesthetized Children.
Mixed venous oxygen saturation (SvO 2 ) is a critical variable in the assessment of oxygen supply and demand but is rarely used in children due to the invasive nature of pulmonary artery catheters. The aim of this prospective, observational study was to investigate the accuracy of noninvasively measured SvO 2 acquired by the novel capnodynamic method, based on differential Fick equation (Capno-SvO 2 ), against gold standard CO-oximetry. ⋯ In conclusion, this first clinical application of a novel concept for noninvasive SvO 2 monitoring without the need for a pulmonary artery catheter indicates that Capno-SvO 2 generates absolute values and trending capacity in close agreement with the gold standard reference method.
