BACKGROUND AND PURPOSE We created a distal internal carotid artery side-wall aneurysm model in dogs and compared its geometric, hemodynamic, and histological similarities with human models. METHODS Eight distal internal carotid artery-shaped devices were constructed using rapid prototyping, and 8 aneurysms were created via surgical reconstruction and elastase incubation. The geometric and hem...

PURPOSE OF REVIEW To discuss the pathophysiological rationale of advanced hemodynamic monitoring in the critically ill and also to highlight the importance of a multimodal, individualized approach. RECENT FINDINGS There are several clinical studies and animal experiments evaluating, which hemodynamic endpoint should be the best target during fluid management. Recent systematic reviews and met...

introduction: hemodynamic alterations are a common complication during anesthetic induction with intravenous anesthesia. hypotension due to propofol injection may be very severe in cardiac vascular patient. ketamine produces the significant increasing but temporary in systematic blood stream, heartbeat, cardiac output through central sympathetic stimulation. objective : to determine effect of k...

objectives this study evaluates the effects of oral tizanidine on hemodynamic responses during operations and aims to determine the appropriate propofol dosage to maintain anesthesia under bis monitoring. materials and methods a double-blind clinical trial has been performed on 70 candidates for elective abdominal surgery undergoing general anesthesia in educational hospital of ghaem, mashhad, ...
