Comparative Study
Hypocalcemia in trauma patients receiving massive transfusion.
Massive transfusion protocol (MTP) is increasingly used in civilian trauma resuscitation. Calcium is vital for coagulation, but hypocalcemia commonly occurs during massive transfusion due to citrate and serum calcium chelation. This study was conducted to determine the incidence of hypocalcemia and severe hypocalcemia in trauma patients who receive massive transfusion and to compare characteristics of patients with severe versus nonsevere hypocalcemia. ⋯ Hypocalcemia is common during MTP, and vigilant monitoring is warranted. Research is needed to effectively manage hypocalcemia during massive transfusion.

Multiply injured patients (MIPs) are at risk to develop multiple-organ failure (MOF) and prolonged systemic inflammation response syndrome (SIRS). It is difficult to predict which MIPs are at the highest risk to develop these complications. We have developed a novel method that quantifies the distribution and physical magnitude of all injuries identified on admission computed tomography scanning called the Tissue Damage Volume (TDV) score. We explored how individualized TDV scores corresponded to MOF and SIRS. ⋯ A novel index that quantifies the magnitude and distribution of mechanical tissue damage volume is a patient-specific index that can be used to identify patients who have sustained injury patterns that predict progression to MOF and SIRS. The preliminary methods will need refinement and prospective validation.

As a common and life-threatening infectious syndrome, sepsis contributes significantly to morbidity and mortality in clinical settings. Vascular endothelial injury and hyperpermeability play an important role in the development of sepsis-induced organ dysfunction. Heat shock protein A12B (HSPA12B) is one of the HSP70 superfamily members and is mainly expressed in vascular endothelial cells. The present study was performed to investigate the role of HSPA12B in endothelial barrier dysfunction during sepsis. ⋯ HSPA12B plays a protective role in vascular endothelial barrier dysfunction by preserving the endothelial permeability during sepsis.

Renal injury is an important complication of infrarenal aortic occlusion (IAO), which is mainly encountered during the postoperative period. Aortic clamping procedure may lead to turbulent blood flow and eventually vasoconstriction at renal arterial level of the abdominal aorta. IL-18BP has well-known antioxidant and anti-inflammatory properties. In this study, we aimed to determine whether IL-18BP has anti-inflammatory, antiapoptotic, antioxidant, and protective effects on acute kidney damage induced by IAO rat model. ⋯ Data established from the present study suggest that IL-18BP may exert anti-inflammatory, antiapoptotic, antioxidant, and protective effects on IAO-induced acute kidney injury in rats.

This study was conducted to investigate whether Xuebijing injection can rectify the dysfunction of microcirculation in septic shock and assessed the microcirculatory parameters directly via orthogonal polarization spectral and software AVA 3.0. ⋯ Based on the adequate fluid resuscitation, Xuebijing injection plays a helpful role of improving microcirculation in septic shock.
