does irrigation and aspiration of intramedullary contents alter the systemic response?

GROUND: Reaming of the femoral canal has been demonstrated to introduce intramedullary contents into the circulation with subsequent pulmonary embolization. The aim of this study was to investigate whether this effect can be minimized by use of a reamer system that provides simultaneous irrigation and aspiration of intramedullary contents. METHODS: A unilateral lung contusion was created and intramedullary femoral nailing was subsequently performed in eighteen female skeletally mature Merino sheep. The animals were divided into three groups, of six animals each, to receive one of three types of treatment: reamed femoral nailing; reaming, irrigation, and aspiration; and unreamed femoral nailing. Blood samples were obtained and a bronchoalveolar lavage was performed at baseline, immediately after creation of the lung contusion, immediately after intramedullary nailing, and at four hours after surgery.
