This monograph focuses on splanchnic function in health and disease. It represents a distillate of the communication that took place at the First International Symposium of Applied Physiol ogy of the Peripheral Circulation, "Splanchnic Circulation: No Longer a Silent Partner." The individual chapters roughly follow the individual presentations and display in durable form the con cepts and importance that this symposium achieved. The concept for this annual symposium was the child of An tonio Artigas, who not only recruited sponsorship but also Jean Francois Dhainaut and me to help with the organization and work. We chose the splanchnic circulation as the peripheral cir culatory system to be presented first for many important reasons. Much new information has become available which demon strates, as the title of the symposium implies, that splanchnic function has major influence on the overall expression of health and disease in humans. All aspects of splanchnic physiology, it seems, have been rediscovered to be dynamic, important, and complex in their interactions within individual tissues and among remote tissues and organs. It is hoped that after having reviewed this monograph the reader will agree that the splanchnic circula tion and its organ systems are emerging as important aspects of critical illness and host-defense homeostasis.

Microcirculation as Related to Shock contains the proceedings of the 1967 Conference on the Microcirculation as Related to Shock held at Boston University. Contributors address reduced blood flow in the microcirculation and microcirculatory hypoperfusion as the focal point of shock. They also review significant progress in shock research, basic cardiovascular physiology, and cognate interdisciplinary fields. This volume is organized into four sections encompassing 26 chapters and begins with an overview of organs and systems involved in shock, including splanchnic circulation, regulatory mechanisms in shock, and microcirculatory studies in hypotension. The next chapters explore the causative factors that produce the state of low blood flow as found in shock, and whether microcirculatory hypoperfusion in humans can be prevented and treated. The book also discusses whether microcirculatory hypoperfusion can be measured in the patient and concludes with an assessment of promising avenues for further research, emphasizing the measurement of blood viscosity, shear stress, and rheological factors as indices of the degree of hypotension. This book is a valuable source of information for physiologists, biologists, and pathologists, as well as those involved in the medical sciences.

This unique book provides clinicians and administrators with a comprehensive understanding of perioperative hemodynamic monitoring and goal directed therapy, emphasizing practical guidance for implementation at the bedside. Successful hemodynamic monitoring and goal directed therapy require a wide range of skills. This book will enable readers to: • Detail the rationale for using perioperative hemodynamic monitoring systems and for applying goal directed therapy protocols at the bedside • Understand the physiological concepts underlying perioperative goal directed therapy for hemodynamic management • Evaluate hemodynamic monitoring systems in clinical practice • Learn about new techniques for achieving goal directed therapy • Apply goal directed therapy protocols in the perioperative environment (including emergency departments, operating rooms and intensive care units) • Demonstrate clinical utility of GDT and hemodynamic optimization using case presentations. Illustrated with diagrams and case examples, this is an important resource for anesthesiologists, emergency physicians, intensivists and pneumonologists as well as nurses and administrative officers.

Advanced Perioperative Crisis Management is a high-yield, clinically-relevant resource for understanding the epidemiology, pathophysiology, assessment, and management of a wide variety of perioperative emergencies. Three introductory chapters review a critical thinking approach to the unstable or pulseless patient, crisis resource management principles to improve team performance and the importance of cognitive aids in adhering to guidelines during perioperative crises. The remaining sections cover six major areas of patient instability: cardiac, pulmonary, neurologic, metabolic/endocrine, and toxin-related disorders, and shock states, as well as specific emergencies for obstetrical and pediatric patients. Each chapter opens with a clinical case, followed by a discussion of the relevant evidence. Case-based learning discussion questions, which can be used for self-assessment or in the classroom, round out each chapter. Advanced Perioperative Crisis Management is an ideal resource for trainees, clinicians, and nurses who work in the perioperative arena, from the operating room to the postoperative surgical ward.

Historically, 20% of all injured combatants die on the battlefield before they can be evacuated to a field hospital. Blood lossâ€"hemorrhageâ€"is the single major cause of death among those killed in action whose lives might otherwise be saved. Fluid resuscitation and the treatment of hypovolemia (the abnormally decreased volume of circulating fluid in the body) offer the greatest opportunity for reducing mortality and morbidity associated with battlefield casualties. In Fluid Resuscitation, a committee of experts assess current resuscitation fluids and protocols for the treatment of combat casualties and make recommendations for future research. Chapters focus on the pathophysiology of acute hemorrhagic shock, experience with and complications of fluid resuscitation, novel approaches to the treatment of shock, protocols of care at the site of injury, and future directions for research. The committee explicitly describes the similarities and differences between acute medical care during combat and civilian emergency trauma care. Fluid Resuscitation should help energize and focus research in both civilian and military emergency care and help save the lives of citizens and soldiers alike.

The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.
