A Multicenter Clinical Study of the Safety and Activity of Maleimide-Polyethylene Glycol–modified Hemoglobin (Hemospan®) in Patients Undergoing Major Orthopedic Surgery

Abstract

In comparison with Ringer's acetate, Hemospan mildly elevates hepatic enzymes and lipase and is associated with less hypotension and more bradycardic events. The absence of a high frequency of serious adverse events suggests that further clinical trials should be undertaken.
