RESUMEN
Objective:To evaluate the effect of M-POSSUM and NRS2002 in predicting the postoperative complications and mortality of abdominal surgery in general surgery.Methods:The M-POSSUM score and NRS2002 score of 121 patients undergoing abdominal major surgery in Department of general surgery were measured by continuous fixed-point sampling,and the receiver operating characteristic (ROC) curve was compared between the two methods.The levels of serum albumin,prealbumin and complications were recorded 1,3 and 7 days after operation.Results:The scores of M-POSSUM and NRS2002 in the complication group were significantly higher than those in the non complication group.The difference was statistically significant (P＜0.05).The scores of M-POSSUM and NRS2002 in the death group were significantly higher than those in the survival group(P＜0.05).The area under curve(AUC) of M-POSSUM,NRS2002 score and the combination of the two methods were 0.795,0.714 and 0.826 respectively.The AUC for predicting mortality were 0.904,0.871,and 0.935,respectively.Albumin and prealbumin were significantly lower than those before operation on 1 day,3 day and 7 day(P＜0.05).The values of albumin and prealbumin in the patients without complications increased significantly on the 7 day after surgery(P＜0.05).There was no significant difference between the patients with complications and the 3 days after operation(P＞0.05).Conclusion:M-POSSUM score and NRS2002 score can effectively predict the complications and mortality after general surgery.Patients with major abdominal surgery have higher nutritional risk,and albumin and prealbumin are significantly lower than those before operation,suggesting that the incidence of complications may increase.
