大肠癌患者术前肠外营养支持对术后胃肠功能恢复的影响

Effects of Preoperative Parenteral Nutrition on Postoperative Recovery of Patients with Colorectal Tumor

目的对比术前肠外营养支持对有无存在营养不良的大肠癌患者术后恢复的影响,以探讨术前营养支持的合理应用。方法回顾分析2008年4月—2009年3月住院行手术治疗的大肠癌患者345例资料,用营养风险筛查评分区别出有、无营养不良,比较术前肠外营养对是否有营养不良患者术后恢复的影响。结果术前使用肠外营养的无合并营养不良的大肠癌患者术后排气时间延长(P<0.05),而术前肠外营养的使用对合并有营养不良的大肠癌患者术后的恢复无促进作用(P>0.05)。结论术前无营养风险的大肠癌患者不宜使用肠外营养,有营养风险的大肠癌患者也应慎用,临床营养支持应该在充分评估患者营养状况的前提下,恰当选择营养支持方式。

Objective Compare the effects of preoperative parenteral nutrition（PN） support on postoperative recovery of colorectal tumor patients who had malnutrition or not,in order to explore how to apply the preoperative nutrition support reasonably.Methods Recalling 345 cases of patients who had been diagnosed with colorectal cancer and went under the knife in Center of Gastrointestinal Surgery from Apr.2008 to Mar.2009,using NRS2002 to get preoperative score of nutritional status to distinguish whether the patients had malnutrition or not,and then comparing the effects of preoperative PN support on patients’ postoperative recovery.Results The patients who were preoperative non-malnourished,preoperative PN would extend the exhausting time（P0.05）,while to the preoperative malnutrition patients,all the postoperative recovery indicators’ differences had no statistical significances.Conclusion Preoperative PN support should not be applied to patients who are non-malnourished,and even be cautiously used to patients who have malnutrition,clinical nutritional support should be reasonably applied based on a full assessment of the patients’ nutritional status and then choose an appropriate method.
