Design outcomes

Primary

Measure	Time frame
Time to demand of the first rescue analgesic in either of the group in the post operative period.Timepoint: patient should be observed immediately at PACU(ZERO minute),2hour,4hour,6 hour,12 hour,24 hour	—

Secondary

Measure	Time frame
The comparison of the total rescue analgesic consumption within first 24 hours after below knee surgeries in both groups.Timepoint: patient should be observed for 24 hours at PACU(zero minute),2 hour,4 hour,6 hour,12 hour ,24 hour;Numerical Rating Scales (NRS) scale at the time, when the patient in either of the groups required rescue analgesic for pain relief.Timepoint: Postoperative pain will be measured using NRS pain scores within 24 hours in both the groups, where the score will be determined by asking the patient to rate the pain from 0-10 where a NRS score of 0 will indicate ?no pain? to NRS score of 10 indicating ?worst pain?.	—
