Acute Circulatory Failure During Surgical Operations

Circulatory failure in acute carbon monoxide poisoning.

Fluid responsiveness in acute circulatory failure.

Although fluid resuscitation of patients having acute circulatory failure is essential, avoiding unnecessary administration of fluids in these patients is also important. Fluid responsiveness (FR) is defined as the ability of the left ventricle to increase its stroke volume (SV) in response to fluid administration. The objective of this review is to provide the recent advances in the detection ...

Mechanical Circulatory Support Devices for Acute Right Ventricular Failure.

Right ventricular (RV) failure remains a major cause of global morbidity and mortality for patients with advanced heart failure, pulmonary hypertension, or acute myocardial infarction and after major cardiac surgery. Over the past 2 decades, percutaneously delivered acute mechanical circulatory support pumps specifically designed to support RV failure have been introduced into clinical practice...

Renin and acute circulatory renal failure in the rabbit.

Plasma renin concentration (PRC) was measured in 25 rabbits before and 6, 24, or 72 hours after subcutaneous injection of glycerol. Renal failure and tubular necrosis developed in most animals and PRC rose sixfold to a maximum at 24 hours. Small insignificant changes of PRC were present at 6 and 72 hours. None of these changes was observed in a control group of nine animals killed 24 hours afte...

Elective circulatory arrest in neurosurgical operations.

Elective peripheral circulatory arrest under moderate hypothermia in neurosurgical operations on intracranial aneurysms and angiomata gives improved operating conditions and a lower mortality and morbidity than previous methods. Circulatory arrest can be achieved by means of intracardiac pacing and placement of a balloon catheter in the ascending aorta, at the same time allowing adequate corona...
