An 18-year-old man developed acute pulmonary edema following heroin overdose. Two days after initial improvement, there was recurrence of hypotension and pulmonary edema with severe hypoxemia refractory to mechanical ventilatory support utilizing positive and end-expiratory pressure. Cardiac

This study evaluated the hypothesis that the postoperative formation of cerebral edema may be influenced by the rate of blood pressure return after induced hypotension in a graded brain retractor injury. Nineteen cats underwent unilateral craniotomy, isoflurane-induced hypotension to a mean of 50 mm

This report illustrates a severe anaphylactoid reaction to sodium diatrizoate infusion during intravenous urography that was characterized chiefly by noncardiogenic pulmonary edema ("shock lung") and protracted hypotension. This occurred in an otherwise previously healthy adult without prior

Spontaneous intracranial hypotension should be considered as a possible cause of cochlear hydrops. We report a case of unilateral hearing loss attributed to spontaneous intracranial hypotension on the basis of characteristic abnormalities seen on magnetic resonance imaging. The diagnostic gold

Objective: We describe three rare cases of spontaneous intracranial hypotension (SIH) presenting with symptoms of endolymphatic hydrops (EH) and perform a literature review to bring attention to a rare link between SIH and EH.

The effect of hypotension on postischemic cerebral edema was studied by the occlusion-reperfusion model of the middle cerebral artery (MCA) of a cat. The middle cerebral artery was transorbitally occluded for 3 hrs and reperfused for 3 hrs. We chose cats whose CBF decreased lower than 10 ml/100

The effects of induced hypotension with isoflurane and labetalol on cerebral edema formation were compared following a cryogenic brain injury in dogs. Thirteen dogs received a maintenance anesthetic of 70% N2O, 0.5% isoflurane in O2 and a fentanyl infusion (3 micrograms.kg-1 x hr-1). All dogs were

Background: Spontaneous intracranial hypotension may be associated with neuro-otological symptoms that might mimic Menière's disease. Case presentation: We report the case of a

Dextran solutions are favored distending media for many hysteroscopic procedures because they are easy to administer, distribute uniformly within the uterine cavity, and are relatively nontoxic. We present the case of a 26-year-old woman who developed hypotension, noncardiogenic pulmonary edema, and

This study examined the effect of exposures to hyperbaric oxygen on the development of the edema and necrosis of muscle that are associated with compartment syndromes that are complicated by hemorrhagic hypotension. A compartment syndrome (twenty millimeters of mercury for six hours) was induced by

BACKGROUND Phenylephrine is a selective alpha(1) adrenergic receptor agonist that increases arterial blood pressure by peripheral vasoconstriction. However, whether phenylephrine improves the outcome of cerebral ischemia in patients with internal carotid artery disease during hemorrhagic shock is

ECG of the month. Hypotension, pulmonary edema, and an irregular cardiac rhythm in a 50-year-old woman. Sinus tachycardia, type I (Wenckebach) second degree atrioventricular block, acute inferoposterior myocardial infarct, and anterolateral myocardial infarct of indeterminate age (probably old).

A 50-year-old woman came to the emergency department because of chest discomfort and dyspnea. She was found to have hypotension, oliguria, and pulmonary edema, i.e., full-blown cardiogenic shock, an irregular rhythm, and no cardiac murmur. The electrocardiogram (ECG) was recorded one lead at a time,

We studied the role of O2 supply and demand factors for producing diaphragmatic failure in a canine model of cardiogenic shock with pulmonary edema. We produced pulmonary edema with oleic acid and then hypotension with cardiac tamponade and followed the animals until respiratory failure began, which

Amlodipine overdose can be life-threatening when manifesting as noncardiogenic pulmonary edema. Treatment remains challenging. We describe a case of noncardiogenic pulmonary edema without refractory hypotension and bradycardia after ingestion of 500 milligram amlodipine with suicidal intent.
