Design outcomes

Primary

MeasureTime frame
Minimum Effective Volume of 0.5% Ropivacaine is calculated by titrating the volume of the drug according to block success or failure in previous patient.Block Success is when Minimal Composite score of 14 out of 16 points achieved(Total Composite score is 16;8 for Sensory and 8 for Motor blockade)Onset of Sensory blockade assessed by cold test(0 no block,1 Analgesia-can feel touch not cold,2 Anaesthesia-cannot feel touch)and Motor blockade by a 3 point scale(0 no block,1 paresis,2 paralysis)Timepoint: 8 time points:time 1, immediately after the procedure;time 2,five minutes after completion of the procedure;time 3,ten minutes after the procedure;time 4, fifteen minutes after the procedure;time 5, twenty minutes after the procedure;time 6, twenty five minutes after the procedure;time 7,thirty minutes after the procedure,time 8,thirty five minutes after the procedure—

Secondary

MeasureTime frame
To assess the Onset time of blockade(time from the injection of LA to achieving a Minimal Composite score of 14)and block performance time(Sum of Imaging time-Time interval between contact of USG probe and getting a satisfactory picture plus needling time-From Start of Skin wheal to the end of Local Anaesthetic injection)Timepoint: 8 time points:time 1, immediately after the procedure;time 2,five minutes after completion of the procedure;time 3,ten minutes after the procedure;time 4, fifteen minutes after the procedure;time 5, twenty minutes after the procedure;time 6, twenty five minutes after the procedure;time 7,thirty minutes after the procedure,time 8,thirty five minutes after the procedure—
