Outcome Measures

Primary Outcome Measures :
  1. Pain at Rest - Part B [ Time Frame: Up to 96 hours ]
    Pain at rest measured by a Numeric Rating Scale (NRS) from time 0 to 96 hours (AUC 0-96). NRS pain scores at rest were collected at 1, 2, 4, 6, 8, 12, 16, 20, 24 and every 4 hours there after post the time of entry into the PACU (while the patient is awake), until discharge from the inpatient until at 96 hour. NRS area under the curve (AUC) is the weighted sum of current pain intensity assessments for a specified time interval. The NRS ranks pain from 0-10; zero being no pain present and 10 being the worst possible pain. Other than 0 and 10, no other pain ratings (2-9) were labeled.


Secondary Outcome Measures :
  1. Evoked NRS - Part B [ Time Frame: Up to 96 hours ]

    Evoked NRS pain scores (three maneuvers: coughing, sitting up, walking) from time 0-96 hours. Evoked NRS scores were obtained twice daily in the morning at 10:00AM (± 1h) and in the afternoon at 4:00PM (±1 h).

    NRS area under the curve (AUC) is the weighted sum of current pain intensity assessments for a specified time interval. The NRS ranks pain from 0-10; zero being no pain present and 10 being the worst possible pain. Other than 0 and 10, no other pain ratings (2-9) were labeled.


  2. Opioid Consumption - Part B [ Time Frame: Up to Day 8 ]
    Total opioid consumption (OC) converted to an oral morphine equivalent (OME) dose from 0 to 96 hours (OC 0-T96) and 0 to Day 8 (OC 0-D8).
