Interval 21.7 to 29.2

SECONDARY outcome

Timeframe: postoperative day 1 day 2, day 3.

Verbal rating scales (VRS): a list of adjectives describing different levels of pain intensity with 0 = no pian and 10 = extremely intense pain. An adequate VRS of pain intensity should include adjectives that reflect the extremes of this dimension; from 'no pain' to 'extremely intense pain'. Patients are asked to read over the list of adjectives and select the word or phrase that best describes their level of pain on the scale from 0 to 10.
