总结1例严重多发伤肠空气瘘患者分段式营养治疗的护理体会。 针对肠空气瘘局部创面大，消化系统连续性遭到破坏，营养支持难度高，采取腹腔开放处瘘口肠管保护及负压辅助关腹技术的护理，结合分段式肠内营养治疗和肠液回输护理。 患者瘘口肠液引流顺利，后期腹壁缺损处愈合良好，肠内营养支持达到目标量，住院60 d后患者康复出院。

In view of the difficulty of wound care around entero-atmospheric fistula，the disruption of the continuity of the digestive system，and the difficulty of nutritional support，the fistula and intestinal tube protection at the open abdomen with vacuum-assisted closure technology was adopted，combined with segmented enteral nutrition therapy and nursing of intestinal fluid reinfusion treatment. The intestinal fluid from the fistula was drained smoothly，and abdominal wall defect healed well in the later period，the enteral nutrition support reached the target amount. After 60-day hospitalization，the patient finally recovered and was discharged.
