[The use of a rapid infusion system in orthopedics]

Major orthopedic surgery such as partial resection of the pelvis and subsequent implantation of a prosthesis is highly connected with massive bleeding. Therefore we tested the hypothesis that the use of a rapid infusion device, which was originally designed for liver transplantations, can prevent hypovolemic shock. We studied 20 patients: in one group (n = 10) the iv volume was given in a conventional way (37 degrees C) by use of pressure infusion bags. Patients of the second group (n = 10) received the iv volume via the Rapid Infusion system (Haemonetics Corp., Braintree, MA). We can conclude that with this new device for rapid volume replacement it is possible to keep the patient's vital functions stable even during times of excessive bleeding and to prevent from metabolic consequences following hypovolemic shock.
