1. If transurethral prostatectomy is a cardiovascular insult this should be reflected by peroperative changes in haemodynamic performance. Little work has been done on this subject. Radioisotope dilution techniques performed before and after transurethral prostatectomy under spinal anaesthesia showed a postoperative fall in cardiac output of 17-5%.'5 Raised pulmonary artery wedge pressure and changes in systemic vascular resistance have been identified in high risk patients undergoing transurethral prostatectomy.'6 In our pilot study using oesophageal Doppler ultrasonography to measure aortic blood flow during routine transurethral prostatectomy we showed significant, early, and progressive haemodynamic responses.'7 Bradycardia and a reduced Doppler index of stroke volume resulted in mean peroperative reductions in cardiac output of;BMJ VOLUME,1992
