Pain Assessment Tool for Postoperative Pain


It is more suitable for measuring the intensity of pain, rather than its duration and nature over time. VAS is recommended, based on its methodological qualities of reliability, validity, sensitivity and relevance to day operations people. He is also one of the most widely used tools for assessing postoperative pain (Gudex et al. 1996, Briggs and Dean 1998). The use of VAS as a tool for measuring pain favor of the defendant, because it uses a few words, and thus less subject dictionary (Flaherty 1996). Provided that clear instructions are given to the respondents, it is enough to fill (Katz and Melzack 1999). In addition, for the appraiser:

• Easy and short, and manage your account (Katz and Melzack 1999);

• This is a good way of expressing pain severity (Scott and Huskisson 1976, Huskisson 1982);

• Because it has the properties of the ratio scale is a true zero point, and, consequently, differences between VAS measurements can be interpreted as a significant interest (Flaherty 1996);

• It is a continuous distribution of frequencies, which allows rigorous statistical tests to be conducted, on average, more levels.

Therefore, we argue that the VAS is more sensitive than the NRS, as the latter may be underestimated and overestimated in the VAS scores, depending on where exactly the VAS score on a scale between any two points of anchor. For example, underestimated the NRS score occurs by rounding down the VAS score of 34.9 mm to 3 on the NRS and the overstatement occurs by rounding points 35.0 mm to 4. This means that the difference of 0.1 mm on the VAS will be a whole difference (3-4) on the NRS. These...
