The types of polycythaemia are reviewed and evidence presented indicating the need for reduction of the packed cell volume in polycythaemic patients before operation. Such patients must also be offered a full regimen of perioperative antithrombosis therapy, the only possible exception being in cases of primary polycythaemia with a bleeding tendency. Either heparin or dextran should be given intravenously and pulsating boots or elastic stockings placed on the patient's legs. An indication is given of the evidence pointing towards mild anaemia, by British standards, being the optimum state for circulatory efficiency and ways of producing this in the polycythaemic patient are described.
本文综述了红细胞增多症的类型，并提供了证据表明，红细胞增多症患者在手术前需要降低红细胞压积。此类患者还必须接受全面的围手术期抗血栓治疗，唯一可能的例外是有出血倾向的原发性红细胞增多症患者。应静脉注射肝素或右旋糖酐，并在患者腿部使用脉动靴或弹力袜。文中给出了证据表明，按照英国标准，轻度贫血是循环效率的最佳状态，并描述了在红细胞增多症患者中产生这种状态的方法。
