This article reviews the development of early ideas regarding the origins and pathogenesis of shock. The early history of shock is related primarily to traumatic shock. More recent history centers on differentiation of clinical syndromes and individual characteristics. ⋯ Progress has been aided by constant development of improved assessment technologies. Today, shock is not a single syndrome and the definition of shock no longer is descriptive in nature. The most accepted current definition involves an oxygen supply/demand imbalance that can have various causes-hypovolemia, cardiac dysfunction, vascular failure, or obstructive processes.

Historical ArticleA history of ethics and law in the intensive care unit.
Because they provide potential benefit at great personal and public cost, the intensive care unit (ICU) and the interventions rendered therein have become symbols of both the promise and the limitations of medical technology. At the same time, the ICU has served as an arena in which many of the ethical and legal dilemmas created by that technology have been defined and debated. This article outlines major events in the history of ethics and law in the ICU, covering the evolution of ICUs, ethical principles, informed consent and the law, medical decision-making, cardiopulmonary resuscitation, withholding and withdrawing life-sustaining therapy, legal cases involving life support, advance directives, prognostication, and futility and the allocation of medical resources. Advancement of the ethical principle of respect for patient autonomy in ICUs increasingly is in conflict with physicians' concern about their own prerogatives and with the just distribution of medical resources.

Posttraumatic stress disorder (PTSD) is a common psychiatric condition that can occur after a traumatic event. Individuals exposed to traumatic events are at risk for PTSD and other psychologic morbidity, such as depression, panic disorder, generalized anxiety disorder, and substance abuse. ⋯ Emerging literature suggests a significantly increased risk for symptoms of PTSD among survivors of critical illness and the families of patients who survive or die after critical illness. This review summarizes these studies and provides suggestions for current clinical implications and for future research.

Psychiatric medications are frequently an essential component of care for critically ill patients. Their use may lead to medical complications, however, as a result of (1) direct toxicity from psychotropic medications, (2) drug-drug interactions, or (3) intoxication or withdrawal states. These complications may be a nuisance (eg, dry mouth and nausea) or serious and life-threatening (eg, neuroleptic malignant syndrome and cardiac arrhythmias). This article addresses the most important medical complications (organized by organ systems) of psychiatric treatment.
