Trial Outcomes & Findings for Liposomal Bupivacaine After Arthroscopic Rotator Cuff Repair (NCT NCT03149887)

NCT ID: NCT03149887

Last Updated: 2020-01-23

Results Overview

Numeric rating score pain level at time of nerve block resolution, on scale of 0-10, as reported by patient at time of 24 hour follow up phone call. A reported score of zero implies no pain, whereas a score of "10" implies very severe pain. Outcome score is mean of reported pain scores by participants at time of nerve block resolution.

PRIMARY outcome

Timeframe: At the time of block resolution, as reported by patients at follow up phone call

Numeric rating score pain level at time of nerve block resolution, on scale of 0-10, as reported by patient at time of 24 hour follow up phone call. A reported score of zero implies no pain, whereas a score of "10" implies very severe pain. Outcome score is mean of reported pain scores by participants at time of nerve block resolution.

SECONDARY outcome

Timeframe: Postoperative day 1

Population: These 51 patients underwent the injection, were assessed for the primary outcome, and completed the questionnaire related to the pain, analgesic and side effects for first three postoperative days (secondary outcomes). Three patients did not fill out this questionnaire and therefore are not included in the reports of secondary outcomes.

Mean NRS pain score on scale of 1-10, at rest (zero is no pain, 10 is severe pain). Patients recorded their pain score at rest with administration of each oral analgesic tablet. Outcome score is mean of reported pain scores for this day.

Population: These 51 patients underwent the injection, were assessed for the primary outcome, and completed the questionnaire related to the pain, analgesic and side effects for first three postoperative days (secondary outcomes). Three patients did not fill out this questionnaire and therefore are not included in the reports of secondary outcomes.

Mean of patient-reported NRS pain scores on postoperative day 2. Patients recorded pain scores at rest with each oral analgesic tablet taken. Zero implies no pain, whereas a score of 10 translates to very severe pain. Outcome score is mean of reported pain scores for this day.

Population: These 51 patients underwent the injection, were assessed for the primary outcome, and completed the questionnaire related to the pain, analgesic and side effects for first three postoperative days (secondary outcomes). Three patients did not fill out this questionnaire and therefore are not included in the reports of secondary outcomes.

Patients recorded their pain scores at rest with ingestion of each oral analgesic table on postoperative day 3. Zero implies no pain, whereas 10 implies very severe pain. Outcome score is mean of reported pain scores for this day.

Timeframe: Mean value of reported pain scores on postoperative days 1,2 and 3

Population: These 51 patients underwent the injection, were assessed for the primary outcome, and completed the questionnaire related to the pain, analgesic and side effects for first three postoperative days (secondary outcomes). Three patients did not fill out this questionnaire and therefore are not included in the reports of secondary outcomes.

NRS Pain score with passive motion (for those patients who performed this), on 0-10 scale, with zero being no pain and 10 representing severe pain. Outcome score is mean of reported pain scores for passive motion episodes on all three postoperative days.
