BACKGROUND Prophylactic treatment of unruptured small brain aneurysms is still controversial due to the low risk of rupture. Distinguishing which small aneurysms are at risk for rupture has become important for treatment. Previous studies have indicated a variety of hemodynamic properties that may influence aneurysm rupture. This study uses hemodynamic principles to evaluate these in the contex...

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, ...

background: to determine if the glidescope® videolaryngoscope (gvl) could attenuate the hemodynamic responses to orotracheal intubation compared with conventional macintosh laryngoscope. objectives: the aim of this relatively large randomized trial was to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using gvl versus mcl amongst healthy adult individuals r...

context despite advancements in the science of surgery, minimizing bleeding from parenchymal tissue of the liver continues to be one of the challenges surgeons are facing to protect patients’ lives. however, the number of surgeries needing incisions in the liver tissue, e.g. metastatectomy, is constantly increasing. conclusions the excessive blood loss and the long time needed to control the bl...

The properties of the hemodynamic latencies in functional maps have been relatively unexplored. Accurate methods of estimating hemodynamic latencies are needed to take advantage of this feature of fMRI. A fully automated, weighted least-squares (WLS) method for estimating temporal latencies is reported. Using a weighted linear model, the optimal latency and amplitude of the fMRI response can be...
