总结1例肠系膜巨大淋巴管瘤致短肠综合征患儿行小肠移植的术后护理体会。术后在早期稳定灌注、防范血栓和出血风险的基础上，针对感染防控、急性排斥反应监测、移植肠造口管理及营养支持等核心难点，护理团队实施了“三重屏障”感染防控措施、“三定一监”抗排斥用药管理、个体化儿童造口护理及阶梯式营养支持方案，通过“五位一体”整合式干预策略，预防儿童ICU后综合征。患儿术后第28天顺利转出儿童重症监护病房。随访5个月，患儿体重增长25%，移植肠功能恢复良好。

This paper summarized the postoperative nursing experience of a child with short bowel syndrome caused by a giant mesenteric lymphangioma who underwent small bowel transplantation. After the operation，on the basis of stabilizing perfusion in the early stage and preventing the risks of thrombosis and bleeding，aiming at the core difficulties such as infection prevention and control，monitoring of acute rejection reactions，management of the transplanted intestinal stoma，and nutritional support，the nursing team implemented “triple barrier” measures for infection prevention and control，the management of anti-rejection drug administration with the principle of “three fixation and one monitoring”，individualized nursing for child’s stoma，and a step-by-step nutritional support plan. The “five-in-one” integrated intervention strategy was adopted to prevent the pediatric post intensive care syndrome（PICS-p）. The child was successfully transferred out of the pediatric intensive care unit on the 28th day after the operation. After 5 months of follow-up，the child’s body weight increased by 25%，and the function of the transplanted intestine recovered well.
