Mast cell stabilization improves cardiac contractile function following hemorrhagic shock and resuscitation.
Hemorrhagic shock (HS) is associated with cardiac contractile dysfunction. Mast cell (MC) degranulation is hypothesized to mediate the cardiodepressant effect. Cardiac function was assessed after HS and resuscitation (HS/R) with the administration of the MC stabilizers to prevent MC degranulation. Anesthetized male Sprague-Dawley rats were randomized to sham-operated control or HS/R groups and ...
متن کاملEsophageal capnometry during hemorrhagic shock and after resuscitation in rats
BACKGROUND Splanchnic perfusion following hypovolemic shock is an important marker of adequate resuscitation. We tested whether the gap between esophageal partial carbon dioxide tension (PeCO2) and arterial partial carbon dioxide tension (PaCO2) is increased during graded hemorrhagic hypotension and reversed after blood reinfusion, using a fiberoptic carbon dioxide sensor. MATERIALS AND METHO...
متن کاملEarly organ-specific endothelial activation during hemorrhagic shock and resuscitation.
Multiple organ dysfunction syndrome (MODS) is a complication of hemorrhagic shock (HS) and related to high morbidity and mortality. Interaction of activated neutrophils and endothelial cells is considered to play a prominent role in the pathophysiology of MODS. Insight in the nature and molecular basis of endothelial cell activation during HS can assist in identifying new rational targets for e...
متن کاملInitial resuscitation of hemorrhagic shock
The primary treatment of hemorrhagic shock is control of the source of bleeding as soon as possible and fluid replacement. In controlled hemorrhagic shock (CHS) where the source of bleeding has been occluded fluid replacement is aimed toward normalization of hemodynamic parameters. In uncontrolled hemorrhagic shock (UCHS) in which bleeding has temporarily stopped because of hypotension, vasocon...
متن کاملNitroglycerin attenuates vasoconstriction of HBOC-201 during hemorrhagic shock resuscitation.
BACKGROUND Vasoconstriction, an inherent property of Hemoglobin Based Oxygen Carriers (HBOC) potentially due to nitric oxide (NO) scavenging, may increase cardiovascular complications in HBOC resuscitated trauma patients. The purpose of this study was to determine if co-administration of a weak NO donor, intravenous nitroglycerin (NTG), with HBOC-201 during resuscitation from hemorrhagic shock ...
