Primary Outcome Measures

Name	Time	Method
Preoperative focused TTE by an independent anaesthetist changes the:<br>a.     diagnosis of haemodynamically significant cardiovascular disease, haemodynamic state or presence of pulmonary oedema made by the treating anaesthetist >30%<br>b.     management plan of the treating anaesthetist or surgeon by >30%<br>compared to prior clinical assessment. <br>A standardized form will be used and variation from planned anaesthetic will be note post TTE/Lung scan[pre-operatively]

Secondary Outcome Measures

Name	Time	Method
Identify the incidence and distribution of clinically significant cardiovascular disease, abnormal haemodynamic state (including pulmonary hypertension, RVSP>60 mm Hg) and pulmonary oedema and pleural effusions.[This will be determined by the TTE/Lung scan and the treating anaesthetist informed pre-operatively];Incidence of vasodilated haemodynamic state and compare to the time interval after last haemodialysis.[pre-operatively at the time of the TTE/lung scan]
