The amount of blood used in transfusions during certain neurosurgical operations was less in 1978-79 than in 1971-72 and in 1965-66. The operations investigated were for gliomas and meningiomas of the brain, pituitary adenomas, acoustic neurinomas, arteriovenous malformations, and arterial aneurysms. The major change in anaesthetic techniques between 1965-66 and 1971-72 was the introduction of hypocapnia by controlled artificial hyperventilation. We suggest that this was the main factor responsible for the reduction in the need for blood transfusions. The avoidance of halothane, the use of induced hypotension, and microsurgical technique may have been responsible for the smaller drop between 1971-72 and 1978-79. Good neurosurgical anaesthesia demands anaesthetic expertise, reliable apparatus, and instant laboratory service, but may also reduce costs by reducing the need for blood transfusions.
在某些神经外科手术中，1978 - 1979年期间输血所用的血量比1971 - 1972年以及1965 - 1966年都少。所研究的手术包括脑胶质瘤、脑膜瘤、垂体腺瘤、听神经瘤、动静脉畸形和动脉瘤。1965 - 1966年至1971 - 1972年期间麻醉技术的主要变化是通过控制性人工过度通气引入了低碳酸血症。我们认为这是导致输血需求减少的主要因素。避免使用氟烷、采用诱导性低血压以及显微外科技术可能是1971 - 1972年至1978 - 1979年期间降幅较小的原因。良好的神经外科麻醉需要麻醉专业知识、可靠的设备和即时的实验室服务，但也可能通过减少输血需求来降低成本。
