Pathophysiology of hemorrhagic shock

Journal of Veterinary Emergency and Critical Care, 2022
AbstractBackgroundHemorrhagic shock is a common condition that may lead to hemodynamic instability, decreased oxygen delivery, cellular hypoxia, organ damage, and ultimately death.Clinical importanceThis review addresses the pathophysiology of hemorrhagic shock.

Vasopressin in Hemorrhagic Shock

Anesthesia & Analgesia, 2005
We describe the treatment of two patients with hemorrhagic shock unresponsive to volume replacement and catecholamines. Both patients responded to a small-dose infusion of vasopressin, which allowed tapering off of the catecholamines. The possible role of small-dose infusions of vasopressin in fluid- and catecholamine-resistant hemorrhagic shock is ...

Treatment of Hemorrhagic Shock

Pediatrics, 1970
Dr. Replogle's recent review of hemorrhagic shock is very well presented. As a result of our experiences with children, as well as severely injured servicemen, we feel that two points may have been overemphasized. These are the emphasis on blood or colloid solutions for volume replacement and the emphasis on the use of the ankle saphenous vein as an ...

Hemorrhagic shock in the monkey

American Journal of Physiology-Legacy Content, 1962
African green monkeys were subjected to varying degrees and durations of hemorrhagic hypotension (arterial reservoir technique) and the shed blood returned. Seven monkeys bled to a mean arterial blood pressure of 50 mm Hg for 5.0 or 6.5 hr, 40 mm Hg for 5.5 hr, or 35 mm Hg for 4.5, 5.0, 5.5, or 6.0 hr survived. Of five monkeys bled to 35 mm Hg for 7.0

Hemorrhagic Shock

2023
Abstract Hemorrhagic shock is a significant cause of morbidity and mortality in trauma and surgical patients. Hemodynamically significant hemorrhage, when coupled with the physiologic derangements associated with trauma and surgery, results in oxygen debt, acidosis, organ dysfunction, coagulopathy, and ultimately death if not treated ...

FLUID THERAPY IN HEMORRHAGIC SHOCK

Survey of Anesthesiology, 1964
The role of cardiac output, blood volume, and peripheral resistance in hemorrhagic shock has been well studied. Changes in the extravascular extracellular fluid and in fluid and electrolytes within the cell, invoked by hemorrhagic shock, have received relatively little attention.

Hemorrhagic Shock in Obstetrics

Clinics in Perinatology, 1986
Hemorrhage during pregnancy is life threatening to both the mother and her fetus. Physiologic preparation for blood loss at parturition does take place but the wise clinician also prepares for this eventuality. The usual causes of hemorrhage are discussed in this article, as well as a useful clinical approach to priorities in the management steps for ...

Microcirculation and hemorrhagic shock

The American Journal of Emergency Medicine, 1984
Blood loss is followed by compensatory cardiovascular readjustments that favor the maintenance of blood flow to central vital organs rather than to peripheral tissues. The microcirculatory changes that occur in skeletal muscle in shock states are of major importance, since skeletal muscle is not only the largest cell mass of the body but also one of ...

Hemorrhagic Shock and the Microvasculature

Comprehensive Physiology, 2018
ABSTRACT The microvasculature plays a central role in the pathophysiology of hemorrhagic shock and is also involved in arguably all therapeutic attempts to reverse or minimize the adverse consequences of shock.

l c t i t z i U o t l r p g a d c t r istorical perspective lthough anecdotal reports of liver trauma such as that f Hellwig and Orr alluded to the effect of shock on the iver, the first large clinical review of liver ischemia was ublished by Bywaters in 1946.
