Pathophysiology and Treatment of Circulatory Shock

Critical Care Clinics, 1993
Circulatory shock is a syndrome characterized by imbalance between oxygen supply and demand. Myriad different mediators are responsible for the systemic manifestations of shock. The therapeutic approach requires initial interventions directed at increasing oxygen delivery followed by definitive therapy for the causative process.

Fluid Resuscitation in Circulatory Shock

Critical Care Clinics, 1993
Over the past century, the treatment of various forms of circulatory shock has included fluid resuscitation with either crystalloidal or colloidal solutions. Despite decades of investigation, there still is considerable controversy over the beneficial and adverse effects of each fluid type.

Shock and Circulatory Homeostasis.

Archives of Internal Medicine, 1959
The transactions of the fifth and final conference on shock and circulatory homeostasis, sponsored by the Josiah Macy Jr., Foundation, brings to the reader the deliberations of a distinguished group of investigators from a variety of professional disciplines, all of them having strong interest in this field, reflected in their substantial contributions

Vasoactive Drugs in Circulatory Shock

American Journal of Respiratory and Critical Care Medicine, 2011
Shock occurs when failure of the cardiovascular system compromises tissue perfusion. When fluid administration fails to restore adequate arterial pressure and organ perfusion in patients with shock, therapy with vasoactive agents should be initiated.

Role of the Lymphatic Circulatory System in Shock

Journal of Burn Care & Rehabilitation, 1987
That the lymphatic vessel participates in the regulation of interstitial dynamics through its ability to contract and propel fluid and protein from the extravascular tissues back to the bloodstream has not been fully appreciated. The "lymph pump" appears to be regulated by local physiologic forces as well as neurogenic and humoral factors.

Nitric Oxide and Circulatory Shock

1998
Key discoveries in the past two decades have proved that the vascular endothelium is more than just a passive barrier between blood vessels and tissues, and have led to many important new concepts in vascular biology and pathophysiology.

Circulatory mechanisms of shock and their mediators

Critical Care Medicine, 1987
Traditional concepts of shock therapy have been based on conventional monitoring. However, the availability of invasive monitoring systems has provided the means to describe the patterns of oxygen transport in various acute life-threatening illnesses.

The role of lysosomes in circulatory shock

Life Sciences, 1976
Abstract Lysosomes are sensitive to the stressful stimuli which develop in the shock states (i.e., ischemia, hypoxia, acidosis). As a result, lysosomal membranes become leaky and tissue lysosomes swell. These conditions are favorable for the leakage of lysosomal contents, largely acid hydrolases, into the cytoplasm of splanchnic cells, particularly ...

Circulatory shock in pregnant sheep

American Journal of Obstetrics and Gynecology, 1974
Uteroplacental and fetal hemodynamics and oxygen transfer were studied in near-term pregnant sheep during progessively induced hemorrhagic shock and blood reinfusion. When the perfusing pressure fell to 50 or 60 mm. Hg, uteroplacental vascular resistance increased significantly and the blood flow fell more than the arterial pressure.
