Clinical Trial
Noninvasive assessment of intra-abdominal pressure by measurement of abdominal wall tension.
Sustained increased intra-abdominal pressure (IAP) has negative effects. Noninvasive IAP measurement could be beneficial to improve monitoring of patients at risk and in whom IAP measurements might be unreliable. We assessed the relation between IAP and abdominal wall tension (AWT) in vitro and in vivo. ⋯ AWT reflects IAP. The epigastric region appears most suitable for AWT measurements. Further longitudinal clinical studies are needed to assess usefulness of AWT measurements for monitoring of IAP.

Children under age 12 y represent 15% of all-terrain vehicle (ATV)-related deaths, and those under 16 y old represent >36% of deaths nationwide. In recent years, this has accounted for an increasing proportion of pediatric trauma victims and longer hospitalizations secondary to worsened injuries. We believe it is possible to create a simple mathematical model that can be used to predict hospital length of stay. ⋯ Based on our data and statistical analysis, we found it was possible to create a mathematical model that could predict hospital LOS in pediatric ATV accident victims.

This study aims to quantify by intravital microscopy the microhemodynamic response after extracorporeal shock wave application (ESWA) to the physiologic microcirculation of the mouse dorsal skinfold chamber. ⋯ This study shows that ESWA provokes a favorable persistent increase of patent capillaries, however accompanied by a transient and slight inflammatory response but also by dose-dependant apoptotic cell death. Our data suggest that ESWA might represent a noninvasive biomechanical tool to treat critically perfused and endangered tissues, but certainly warrants further investigation.

Lower limb ischemia-reperfusion (I/R) elicits oxidative stress and causes inflammation in lung tissues that may lead to lung injury. Magnesium sulfate (MgSO(4)) possesses potent anti-oxidation and anti-inflammation capacity. We sought to elucidate whether MgSO(4) could mitigate I/R-induced lung injury. As MgSO(4) is an L-type calcium channel inhibitor, the role of the L-type calcium channels was elucidated. ⋯ MgSO(4) mitigates lung injury induced by bilateral lower limb I/R in rats. The mechanisms may involve inhibiting the L-type calcium channels.

Dobutamine (DB) has been recommended in combination with vasopressor therapy in septic shock, given its reported ability to improve mesenteric and microcirculatory perfusion. Vasopressin (VP) is typically reserved as a second-line agent due to the concern of ischemia. The purpose of our study was to determine whether combination DB and VP therapy improved microcirculatory blood flow in severe endotoxic shock. ⋯ Results indicate that DB is ineffective in increasing CO or improving mesenteric blood flow when used with physiologic replacement doses of VP. In combination, DB is unable to overcome the blood flow distribution achieved with VP administration alone in severe endotoxic shock.
