ABSTRACT
Objectives: To test our hypothesis that a new modified VAS [mVAS] is superior and more objective than VAS in evaluating pain perception and treatment response between genders who have renal colic pain
Methods: The individuals in patient and control groups were first asked to mark the pain perceived during access of IV line [VAS[IV] score]. Then the patients with renal colic were asked to mark the pain they experienced before treatment [VAS[RC] score] and at 15 and 30 minutes after the administration of the first analgesic drug. The modified VAS scores [mVAS score] were obtained by subtracting the VASIV score from VAS[RC] score
Results: When VAS was used, the female patients had significantly higher level of pain at 0, 15, and 30th minutes than men [p = 0.012, p = 0.001, and p = 0.003, respectively]. However, there was not any significant difference at 0 and 30[th] min between sexes while female patients had significantly higher level of pain scores only at 15[th] minute according to mVAS scores [p = 0.027]
Conclusion: We think that the mVAS is superior and more objective than VAS in evaluating pain perception and abolished the difference in the perceived level of pain due to gender
