Impedance Cardiography (ICG) is a noninvasive technique for monitoring stroke volume, cardiac output and other hemodynamic parameters, which is based on sensing the change of thoracic electrical impedance caused by blood volume change in aorta during the cardiac cycle. Motion artifact and respiratory artifact can lead to baseline drift in ICG signal, particularly during or after exercise, which...
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...
BACKGROUND Pulmonary hypertension is a contradiction for heart transplantation (HTx). The aim of the study was to examine prognostic significance of pulmonary hemodynamic variables in patients with severe chronic heart failure (HF) considered for HTx. METHODS Patients with HF were qualified to HTx in Poland. We measured pulmonary artery systolic pressure (PASP), pulmonary capillary wedge pres...
Amifostine reduces nephrotoxicity and myelotoxicity of alkylating agents. Little is known about its role in preventing cardiotoxicity. We studied if amifostine could affect the hemodynamic parameters in doxorubicin-pretreated rabbits. The animals were divided into six groups consisting of 6 rabbits each. Group 1--doxorubicin iv 2 mg/kg of body weight 4 times every 14 days (cumulative dose 8 mg/...
While certain parameters such as blood loss and serum lidocaine levels following liposuction have been well studied, fluid shifts between the intravascular and extravascular space have not. With the advent of large volume liposuction, prudent fluid management has become obligatory. Hence, the reason for our study.To test the impact of large volume infiltration on intercompartmental fluid shifts...
INTRODUCTION Standard procedures carried out at a stroke department in patients after a cerebral event may prove insufficient for monitoring hemodynamic indices. Impedance cardiography enables hemodynamic changes to be monitored non-invasively. The aim of the work was to describe hemodynamic parameters in patients with acute phase of ischemic and hemorrhagic stroke and to analyse the correlatio...
In patients with atherosclerotic internal carotid artery or middle cerebral artery occlusive disease, chronic reduction in cerebral perfusion pressure (chronic hemodynamic compromise) increases the risk of ischemic stroke and can be detected by directly measuring hemodynamic parameters. However, strategies for selecting treatments based on hemodynamic measurements have not been clearly establis...
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...
