Observational Study
A noninvasive hemoglobin monitor in the pediatric intensive care unit.
Critically ill pediatric patients frequently require hemoglobin monitoring. Accurate noninvasive Hb (SpHb) would allow practitioners to decrease anemia from repeated blood draws, traumatic blood draws, and a decreased number of laboratory Hb (LabHb) medical tests. The Food and Drug Administration has approved the Masimo Pronto SpHb and associated Rainbow probes; however, its use in the pediatric intensive care unit (PICU) is controversial. In this study, we define the degree of agreement between LabHb and SpHb using the Masimo Pronto SpHb Monitor and identify clinical and demographic conditions associated with decreased accuracy. ⋯ The Masimo Pronto SpHb Monitor provides adequate agreement for the trending of hemoglobin levels in critically ill pediatric patients. However, the degree of agreement is insufficient to be used as the sole indicator for transfusion decisions and should be used in context of other clinical parameters to determine the need for LabHb in critically ill pediatric patients.

Sepsis is one of the most troublesome problems in critically ill patients and often accompanied with multiple organ dysfunction and high mortality. Gut injury or dysfunction may contribute to the pathogenesis of sepsis. Neutrophil extracellular traps (NETs) do not only kill microorganisms but also damage host cells during inflammatory response to infection. The aim of this study was to investigate whether NETs are capable of promoting the impairment of the gut in a rat model of lipopolysaccharide (LPS)-induced sepsis. ⋯ This study demonstrates that the release of NETs may contribute to the intestinal damage during sepsis.

Racial disparities remain for women undergoing immediate breast reconstruction (IBR) after mastectomy. Understanding patterns of racial disparities in IBR utilization may present opportunities to tailor policies aimed at optimizing care across racial groups. The aim of this study was to determine if racial disparities exist for types of IBR chosen. ⋯ Utilization of IBR may be a sensitive measure of disparities in access to high-quality care and underlying cultures. Strategies aimed at reducing racial disparities in IBR should be tailored to specific patterns of disparities among Asian, black, and Hispanic women.

Emerging therapies for prolonged cardiac arrest (CA) include advanced circulatory interventions like emergency cardiopulmonary bypass (ECPB) and continuous venovenous hemofiltration (CVVHF). However, preclinical studies are limited because of the absence of a practical method of using CVVHF along with ECPB in rodents. ⋯ We developed a method of CVVHF along with ECPB in rodents after CA. We further demonstrated the ability to regulate both standard and HV filtration rates.

Ischemia-reperfusion injury caused by severe hemorrhagic shock and subsequent resuscitation leads to deterioration of hepatic homeostasis and possibly to liver failure. The present study focuses on determining whether there is a different biological response to hemorrhagic shock by different sources of hemorrhage, hepatic hemorrhage (HH) versus peripheral hemorrhage. ⋯ Our study provides evidence that HH entails worse consequences for the hepatocytes than systemic hemorrhage. Higher needs for resuscitation fluids, decreased proliferation, and augmented inflammatory response when HH takes place are findings with possible clinical importance in liver surgery and trauma.
