2.6. Evaluation of pain:
A numeric rating scale (NRS) was used for pain assessment. The NRS is a
segmented numeric version of the visual analog scale (VAS) in which a
respondent selects a whole number (0-10 integers) that best reflects the
intensity of his / her pain. It is considered a unidimensional measure
of pain intensity in adults. The 11-point numeric scale ranges from ’0’
representing one pain extreme (”no pain”) to ’10’ representing the other
pain extreme (”pain as bad as you can imagine” or ”worst pain
imaginable”). NRS pain score was evaluated at 30th minute and 1st, 2rd,
3th, 6th, 12th and 24th hours.
