Evaluation of pain
postoperative pain, NRS, pain
Numeric Rating Scale (NRS), which is a numerical scale in which the respondent selects an integer (0–10 integer) that best reflects the intensity of the pain, was used to assess the postoperative pain. In this regard, “0” meant “no pain” and “10” meant “worst pain imaginable”.The NRS scores at rest and in motion were recorded by an anesthetist who did not know the group distributions at postoperative min 0, min 15, min 30, min 60, 2nd hour, 6th hour, 12th hour, and 24th hour. Patients were educated and familiarized with NRS scores at the preoperative period.
