Abstract：Objective:To probe into the relationship between intra abdominal pressure variation rate and post-operative jejunum nutrition of gastric cancer patients.Methods:A total of 85 cases of patients with gastric cancer undergoing operation from 201 1 January to 2013 June,according to the 24 h IAP changes,the postoperative pa-tients were divided into group A (24 h IAP >20% increased,n =28),group B(24 h IAP increased- 20% ~20%,n=33)and group C(24 h<-20% IAP to increase the rent,n =24).The nutritional index changes and postoperative ventilation,defecation time and jejunum nutrition tolerance of patients were compared among 3 groups.Results:There was statistically significant difference in postoperative prealbumin,retinol binding protein and albumin among 3 groups.The postoperative prealbumin,retinol binding protein and albumin of group A and group B were lower than those in group C,and the difference was statistically significant (P <0.05);there was statistically significant difference in postoperative ventilation,defecation time and jejunum nutrition tolerance of patients among 3 groups (P <0.05);IAP was negatively correlated with nutrient tolerance of patients (P<0.05);the single factor analysis showed that the influencing factors of nutrition tolerance included Apache III,IAP and age;multi factor analysis showed that the influencing factors of nutrition tolerance were Apache III and IAP. Conclusion:IAP variability is correlated with postoperative nutrition tolerance of patients with gastric cancer,the influencing factors of nutritional tolerance include Apache III and IAP,and IAP is one of the important indexes of assessing postoperative jejunum nutrition status of patients with gastric cancer.
