Trial Outcomes & Findings for Postoperative Opioid Use and Pain Scores in Patients Undergoing Transforaminal Lumbar Interbody Fusion (NCT NCT02061774)

NCT ID: NCT02061774

Last Updated: 2020-05-06

Results Overview

The Visual Analogue Scale (VAS) and Verbal Rating Scale (VRS) will be measured at 4 hour intervals for a 24-hr period - measures of pain intensity in clinical and research settings. 0-10 Numeric pain intensity scale. 0 is no pain, 5 is moderate pain, and 10 is worst possible pain

Sedation will be measured on a scale of 1 to 5 at 4-hour intervals as follows: 1-completely awake; 2-awake but drowsy; 3 asleep, but responds to verbal commands; 4-asleep but responds to tactile stimuli; and 5-asleep and not responding to any stimuli.

SECONDARY outcome

Timeframe: 4-hour intervals (+/- 30 minutes) for 24-hrs averaged

Routine postoperative vital signs will be collected at 4-hour intervals (+/- 30 minutes) postoperatively respiratory rate, oxygen saturation, mean arterial pressure, and heart rate. Any reports of headache, dizziness, nausea, vomiting, pruritis, agitation, constipation, insomnia, bradycardia (Heart rate below 60 beats per minute), hypotension (MAP less than 30% of baseline), or urinary retention will be recorded throughout the study and will be treated appropriately as they occur, and the treatment medication will be stopped if determined to be a causative factor.
