Research on hemorrhage has concentrated on its effects rather than the manner of occurrence. A new experimental method in which the rate of bleeding is a function of prevailing arterial pressure is proposed and described. The effects of standard crystalloid volume expansion and of small volume hypertonic treatment on this protocol are demonstrated. In(More)
It is controversial whether rotation is necessary for patients undergoing pleurodesis. In addition, the optimal volume of the injectate remains to be determined. The purpose of this study was to determine the importance of rotation and the volume of the agent on the intrapleural dispersion of agents injected into the pleural space of rabbits.

In pressure-driven hemorrhage (PDH), where the rate of bleeding is a function of prevailing arterial pressure, survival time, arterial pressure, cardiac output, oxygen consumption, and base excess are functions of initial bleeding rate. The quantitative rate of transcapillary refill (TR) throughout PDH leading to death was determined in splenectomized dogs,(More)
Two different hypertonic (2400 mOsm/L) isochloremic dextran solutions (sodium acetate, HAD; and sodium lactate, HLD; in 0.9% NaCl + 6% dextran 70) were compared with HSD (2400 mOsm/L NaCl + 6% dextran 70) as initial treatment for severe uninterrupted arterial bleeding. The substitution of dextran 70 for lactated Ringer's solution as the maintenance isotonic(More)
PURPOSE OF REVIEW This article reviewed very recent papers (2016) discussing or bringing clinical evidences of the possible common pathways leading to diabetic foot syndrome (DFS) and increased mortality rates. RECENT FINDINGS Diabetic patients with diabetic foot syndrome have a mortality rate greater than twofold when compared with non-ulcerated(More)
