Design outcomes

Primary

MeasureTime frame
To asses the diagnostic power of changes in objective measures such as hemodynamic variables and perfusion index to predict successful parasacral ischial plane blockTimepoint: Before block administration and at 10 minutes, 20 minutes,30 minutes and 40 minutes after block administration—

Secondary

MeasureTime frame
1.Changes in perfusion index and regional hemodynamic variables such as peak systolic velocity(PSV), end-diastolic velocity (EDV) , time-averaged maximum velocity (Tmax) and time-averaged mean velocity (Tmean) of popliteal artery following parasacral ischial plane nerve block. 2. Comparison of objective parameters with subjective parameters in terms of sensitivity, specificity, PPV and NPV.Timepoint: Before block administration and at 10 minutes, 20 minutes,30 minutes and 40 minutes after block administration—
