Haemodynamic and central venous pressure changes in transurethral resection of prostate during general, spinal and epidural anaesthesia: A comparative study

Abstract

During transurethral resection of prostate (TURP) both intravascular and extra vascular absorption of irrigating fluid may lead to adverse cardiovascular effects and myocardial damage. This prospective study is aimed to compare central venous pressure and haemodynamic changes with different techniques of anaesthesia and to find the best possible technique. We randomly allocated 90 elderly patients (ASA I, II III) into three equal groups receiving either general anaesthesia (Group A), spinal anaesthesia (Group B) or epidural anaesthesia (Group C) for transurethral resection of prostate (TURP). It was observed that the MAP increased by 11% from preinduction values to the completion of surgery in group A while a decrease of 11.2% was observed in group B but only minimal changes in group C. There was decrease in heart rate of 14% and 17% in group A& C respectively but maximum decrease was in group B of 21%. CVP was raised from basal value up to 77%, 44% and 42% and in group A, B and C respectively. Thus, patients who received epidural anaesthesia had minimal changes in haemodynamics.
