Thoracic bio-impedance cardiography was used to study the haemodynamic changes in 28 patients undergoing transurethral prostatectomy (TURP) under either general or spinal anaesthesia. Cardiac output and mean arterial pressure fell with induction of general anaesthesia, whilst mean arterial pressure and systemic vascular resistance fell with induction of spinal anaesthesia. The transthoracic fluid index fell during resection under general anaesthesia, but no significant haemodynamic changes were seen during resection under either anaesthetic. This study suggests that resection has no specific adverse haemodynamic consequences. Spinal anaesthesia may produce less haemodynamic disturbance than general anaesthesia in patients undergoing TURP and formal comparison of the 2 techniques seems necessary.
采用胸阻抗心动图研究28例接受全身麻醉或脊髓麻醉下行经尿道前列腺切除术（TURP）患者的血流动力学变化。全身麻醉诱导时心输出量和平均动脉压下降，而脊髓麻醉诱导时平均动脉压和全身血管阻力下降。全身麻醉下切除过程中经胸液体指数下降，但两种麻醉下切除过程中均未观察到明显的血流动力学变化。本研究提示，切除手术无特定的不良血流动力学后果。对于接受TURP的患者，脊髓麻醉可能比全身麻醉产生的血流动力学干扰更小，似乎有必要对这两种技术进行正式比较。
