THE INVESTIGATION OF CORRELATIONS OF PAIN SCORING SYSTEMS USED IN EVALUATING ANALGESIC EFFECTS AFTER ABDOMEN OPERATIONS
ABSTRACT
Objective: It was planned to investigate the correlation of Numerical pain scale (NRS) and Prince Henry pain scale (PHPS) scoring systems used to assess postoperative pain levels.
Materials and Methods: Seventy-five patients who underwent unilateral inguinal hernia repair from ASA I-III over the age of 18 years were included in the study. Transversus Abdominis Plan (TAP) Block was applied to each patient at the end of the operation for standard postoperative analgesia following standard general anesthesia. Demographic data of the patients and postoperative 0., 2., 4., 6., 8., 12.hour nausea at time, presence of vomiting, need for additional analgesia, NRS and PHPS values were compared.
Results: Demographic characteristics of the cases and postoperative analgesic usage times are also seen. Nausea was observed in 20% (n=15) and vomiting in 2.7% (n= 2). There were statistically significant difference between NRS values and PHRS at 0., 2., 4., 6., 8. and 12. hours (respectively p = 0,001, p <0,01, p = 0,001, p <0,01). The relationship between the two pain scores was assessed by Spearman's correlation analysis and ICC, and the relationship between the two pain scores was found statistically significant in both cases. PHPS scores of the cases were found at time 0 (r = 0,773; p <0,01) among the NRS scores; 2nd hour (r = 0,711; p <0,01); At 4th hours (r = 0.725; p <0,01); At 6th hours (r = 0,640; p <0,01); Positive correlations were found statistically significant at 8th hour (r = 0,786; p <0,01) and 12th hour (r = 0,743; p <0,01)
Conclusion: PHPS also provides an effective assessment, such as NRS, in assessing pain after abdominal operations. We believe that PHPS can provide a more objective assessment especially during the early postoperative period. However, larger, heterogeneous sampling studies are needed.
