Outcome Measures

Primary Outcome Measures :

Analysis of Total Pain Relief (TOTPAR) Over 0 to 12 Hours (TOTPAR-12) After Time 0 [ Time Frame: Over 0 to 12 Hours ]
Total pain relief as computed as a time-weighted sum of individual patient pain relief scores at each timepoint from 0-12 hours.

Values for TOTPAR are measured from 0 to 4 on the Pain Relief Scale 0 None Min; 1 A little; 2 Some; 3 A lot; 4 Complete Max

The TOTPAR is a weighted measure of the observations; the minimum possible value is 0 and the maximum possible value is 60.
