groups, group I(received 5ml bupivacaine 0.5% with 5ml normal
saline each side in the block)& group II (given5ml bupivacaine0.5%
with 5ml normal saline containing ketamine 0.5mg/kg each side in
the block) 50 patients each. After approval from the Local Ethical
Committee and all patients had informed written consent of the study.

0.5% with a 25-gauge Whitacre pencil-point needle inserted between
the lumbar intervertebral space 4/5 under aseptic conditions.
group I: received Ultrasound guided pudendal nerve block
on both sides using 10 ml volume each side (5 ml bupivacaine
0.5% and 5 ml normal saline ) after saddle block.
group II: Received Ultrasound guided pudendal nerve block
on both sides using 10 ml volume each side (5 ml bupivacaine
0.5% and 5 ml normal saline containg ketamine 0.5mg/kg)
