Description/Abstract The Trendelenburg position is used frequently in treating hypotensive patients.^It is believed that placing patients in the Trendelenburg position causes an autotransfusion of blood to the central circulation.^No published studies document the volume of blood displaced centrally.^In this study ten volunteers were placed in the Trendelenburg position.^Blood volumes were determined from body surface area, and radionuclide scanning was used to determine blood volume distribution.^Placing normovolemic volunteers in the Trendelenburg resulted in a 1.8% (median) displacement of the total volume centrally.^The autotransfusion of blood produced by the Trendelenburg position is small and is unlikely to have an important clinical effect.
