胃肠道手术后规范化序贯肠内肠外营养支持疗法与肠外营养支持的临床随机对照研究

目的 比较胃肠道手术后规范化序贯肠内肠外营养支持疗法与肠外营养支持的临床疗效.方法 采用随机数字表法,将126例拟行开腹胃肠道手术的患者随机分为早期肠内肠外营养支持疗法组(EEN+PN组,n=62)和肠外营养支持组(PN组,n=64),分别于手术前,手术后第3、7天监测患者的体重、体重指数、血清白蛋白、前白蛋白、血脂、血生化、血淋巴细胞计数、血C反应蛋白变化情况,比较两组患者术后胃肠道功能恢复时间、手术并发症、营养支持相关费用及住院天数.结果 术前两组患者的营养相关指标、血生化指标和炎症及免疫指标差异均无统计学意义(P>0.05);术后第3天,EEN+PN组患者前白蛋白水平显著高于PN组[(160.3±23.0)g/L比(137.0±28.7)g/L,P=0.000];术后第7天,EEN+PN组患者前白蛋白[(210.6±34.6)g/L比(154.8±36.9)g/L,P=0.000]、白蛋白[(33.6±3.8)g/L比(31.8±4.7)g/L,P=0.042]、淋巴细胞计数[(2.33±0.53)×109/L比(1.04±0.36)×109/L,P=0.046]水平均显著高于PN组,血γ-谷氨酰转肽酶[(48.12±33.84)U/L比(71.54±34.00)U/L,P=0.048]、C反应蛋白[(31.15±19.00)mmol/L比(45.90±23.21)mmol/L,P=0.042]、总胆固醇[(3.09±0.83)mmol/L比(3.29±0.91)mmoL/L,P=0.045]、低密度脂蛋白[(2.01±0.39)mmoi/L比(2.31±0.72)mmol/L,P=0.049]水平显著低于PN组.EEN+PN组患者术后胃肠道功能恢复时间显著短于PN组[(65.7±15.6)h比(75.1±27.0)h,P=0.036],围手术营养支持疗法总费用显著低于PN组[(2634.5±1306.8)元比(3058.6±1216.0)元,P=0.046].结论 胃肠道手术后早期规范化序贯肠内肠外营养支持疗法可以改善机体术后前白蛋白水平,有益于术后患者免疫功能和组织损伤水平的恢复,促进早期胃肠道功能恢复,降低营养支持疗法相关费用.

Abstract：

Objective To compare the clinical efficacy between standard sequential early enteral nutrition (EEN) plus parenteral nutrition (PN) and PN alone in patients undergoing gastrointestinal surgery. Methods Werandomly divided 126 patients who underwent laparotomy gastrointestinal surgery into EEN + PN group (n = 62) and PN group (n = 64). The levels of blood nutrition-related indicators, biochemical indicators, and inflammatory indicators were determined before surgery and 3 and 7 days after surgery, and the gastrointestinal function recovery time, complications, nutritional support cost, and length of hospital stay were compared between two groups. Results The preoperative nutrition-related indicators, biochemical indicators, and inflammatory indicators showed no significant differences between two groups (P >0. 05). Three days after operation, however, the levels of prealbumin in EEN + PN group were significantly higher than those in PN group [(160. 3 ±23. 0) g/L vs. (137.0±28.7) g/L, P=0.000]. Seven days after operation, the levels of albumin [(33.6±3.8) g/L vs. (31.8±4.7) g/L, P = 0.042], prealbumin [(210.6±34.6) g/L vs. (154.8 ±36.9) g/L, P=0.000], and lymphocyte cell count [(2.33±0.53) x 109/L vs. (1.04±0.36) × 109/L, P = 0. 046] in EEN + PN group were significantly higher than those in PN group, and the levels of serum γ-glutamyltransferase [(48. 12 ± 33.84) U/L vs. (71.54±34.00)U/L, P=0.048], C-reactive protein [(31.15 ± 19.00) mmol/L vs. (45.90 ± 23.21) mmol/L, P=0.042], total cholesterol [(3.09±0.83) mmol/L vs. (3.29±0.91) mmol/L, P = 0. 045] and low density lipoprotein [(2.01 ± 0. 39) mmol/L vs. (2. 31 ± 0. 72 ) mmol/L, P = 0. 049] were significantly lower than those in PN group. The postoperative gastrointestinal function recovery time in EEN + PN group was significantly shorter than that in PN group [(65. 7 ± 15. 6) hours vs. (75. 1 ± 27. 0) hours, P = 0. 036], and the total cost of perioperative nutrition in EEN + PN group was also significantly lower than in PN [(2634. 5 ±1306. 8) RMB vs. (3058. 6 ± 1216. 0) RMB, P= 0.046]. Conclusion Standard sequential EEN plus PN can increase the post-operative prealbumin level, improve the immune function, promote the recovery of gastrointestinal function, and decrease the cost of nutritional support.
