Effect of Hypocaloric Parenteral Nutrition on Postoperative Recovery in Aged Patients with Gastric Cancer

Objective: To observe the effect of hypocaloric parenteral nutrition(PN) regimen on the postoperative recovery in aged patients with gastric cancer. Methods: Sixty aged patients with gastric cancer were divided into observation group (n=30) and control group (n=30) on the basis of postoperative PN feeding strategies.The observation group received hypocaloric PN which contained calorie 18 kcal/kg/d and nitrogen 0.1 g/kg/d. And the control group received calorie 30 kcal/kg/d and nitrogen 0.2 g/kg/d. Both groups have been provided with PN for 6 days continuously .The differences regarding C-reactive protein(CRP), serum albumin, blood glucose, infectious complications and duration of hospital stay were compared between the two groups. Results: CRP level on the 6th day in observation group was significantly lower than that in control group, while levels of serum prealbumin and transferrin in observation group were higher than those in control group (P＜0.05). There was no significant difference regarding blood glucose concentration between the groups, but the dose of insulin administered on the 6th day in observation group was significantly lower than that in control group (P＜0.05). And both infectious complications and duration of hospital stay in observation group were fewer than those in control group (P＜0.05). Conclusions: Hypocaloric PN regimen was conducive to postoperative recovery in aged patients with gastric cancer.
