M-the Possum And Nrs Correlation With Clinical Outcome

Objective:Application of the nutritional risk screening 2002 and modified POSSUM scoring system on the general surgical operative risk in patients with major abdominal surgery to assess, to evaluate the combination and alone in predicting postoperative complications in general surgery and mortality.And to study the Screening of Nutritional Risk and nutritional recovery of patients with major abdominal surgery before and after operation, and its relations with complications. Methods:we followed up for 81 cases of general surgical patients undergoing major abdominal surgery, observed the correlation of the nutritional risk screening 2002,modified POSSUM scoring system and a combination of both, and prediction of postoperative complications and mortality of the ROC curve.The NRS scoring system was performed on 81 patients with major abdominal surgery before and after operation, and the nutritional recovery was also surveyed by observing changes of Albumin and Prealbumin before and after operation. Results:The correlation coefficient of M-POSSUM score and the combination of both was 0.948 (P= 0.00); The correlation coefficient of NRS score and the combination of both was 0.589 (P =0.00); The area under the ROC curve of three score in predicting complications were 0.892,0.804,0.723; The area under the ROC curve of predict mortality were 0.936,0.916,0.869.The NRS score of 81 patients with major abdominal surgery, the number of patient with score≥3 was 19 before operation and 44 after operation, and the number of patient with score<3 was 62 before operation and 37 after operation when evaluating the 81 patient with NRS 2002. In the first month after operation. There were 9 patients who appeared complications in the 19 patients with score≥3 before operation. There were 11 patients who appeared complications in the 61 patients with score< 3 before operation. Application of X2 tests,There were significant differences between the two groups.Compared with the preoperative, the postoperative Albumin and Prealbumin of all patients are lower, and they still didn't recovered until 7 days after operation in the group of score>3 before operation, whereas they had risen again on postoperative 7 day in the group of score<3 before operation. Conclusion:The nutritional risk screening 2002,modified POSSUM scoring system and the combination of both have a good correlation, the three score have equally effective general surgical in predicting complications and mortality; The combination of both better than the two alone under the performance of initial observation.Patients with major abdominal surgery have a higher nutritional risk. The Albumin and Prealbumin decreased after operation. It may suggest that the incidence of postoperative complications would increase when the patients with score>3 before operation.
