BACKGROUND AND PURPOSE Hemodilution in the acute phase of ischemic stroke is still controversial. Multicenter studies have failed to demonstrate any benefit. The present study focuses attention on analysis of circulation in stroke and on individual restabilization of circulation. METHODS The Amsterdam Stroke Study is a prospective, single-center, randomized clinical trial (n = 300). Normovole...

At present, individual techniques, including intraoperative acute normovolemic hemodilution, use of tranexamic acid, use of intrathecal morphine, proper positioning, and modification of operative techniques, seem most promising for reducing perioperative blood loss and allogeneic blood transfusion in patients undergoing major spine surgery. Other techniques including preoperative autologous pre...

Rigorous control procedures adopted presently by blood banks have reduced transfusionassociated risks, such as transmission of infectious diseases. Nevertheless, other complications related with blood-transfusions remain, such as transfusion-related acute lung injury (TRALI) and other immune disorders. In critically ill patients, transfusion has been associated with increase in morbidity and mo...

BACKGROUND AND OBJECTIVES Acute Normovolemic Hemodilution (ANH) is a simple and low-cost autologous transfusion method. This study aimed at evaluating whether ANH is able to decrease homologous transfusions in children undergoing posterior spinal fusion and at verifying hemodilution-induced complications in those patients. METHODS Participated in this study 25 children, physical status ASA I ...

Poor condition subarachnoid hemorrhage (SAH) patients present a high mortality and morbidity. In this study, we reviewed the acute interventional (surgical and endovascular) management of 109 SAH-poor condition patients, who were treated as early as logistically possible after confirming stable circulation parameters. Patients over the age of 70 years, without clinical response to painful stimu...

BACKGROUND Preoperative autologous blood donation is accepted as a standard of care for radical prostatectomy. Acute normovolemic hemodilution (ANH) is an alternative method for obtaining autologous blood. The cost and benefits of these two autologous blood-collection techniques are compared. STUDY DESIGN AND METHODS Thirty consecutive patients scheduled for radical prostatectomy underwent AN...

Hemodilution is one of the sequelae of cardiopulmonary bypass (CPB). Autologous blood priming (retrograde autologous priming [RAP]/venous antegrade priming [VAP]) and acute normovolemic hemodilution (ANH) may be effective techniques to minimize hemodilution. The primary objective of this study is to investigate the impact of RAP/VAP combined with ANH on changes in cerebral saturations. A retros...

The effect of isovolemic hemodilution on red blood cell flow distribution was studied in complete self-contained microvessel networks of the rat mesentery. Hematocrit, diameter, and length of all vessel segments as well as the topological structure were determined in control networks (systemic hematocrit, 0.54) and after hemodilution (systemic hematocrit, 0.30). Hemodilution was performed by ex...

Objective: To investigate the effect of acute normovolemic hemodilution (ANH) combined with controlled hypotension (CH) on extravascular lung water and systematic oxygen metabolism for elderly patients, and to explore the clinical security of ANH + CH. Methods: 45 elderly patients undergoing elective spine and hip replacement surgery were selected and randomly divided into 3 groups (n=15 in eac...
