猪小肠移植的围手术期管理

实验于2004-02／2006-05在哈尔滨医科大学附属第二医院完成。杂种小猪40只，供体20只，受体20只。①供体手术：原位腹主动脉4℃肝索盐水500mL耀洗，灌洗压力为7．8～9．8kPa，快速切除供体肠管后置于4℃生理盐水中保存。②受体手术：根据探查情况，分别行原位和异位小肠移植。40～45℃生理盐水冲洗腹腔，直至吸引出的冲洗液变温暖为止。③围手术期管理：移植前、移植后讨论，注意体温的监测和控制，尝试早期进食，其中4只移植后自由进水，第2天给予正常饮食，其余移植后2d进水。④移植后评估：实验动物进食后无吻合口漏发生。16只存活超过7d，最长存活超过14d。平均存活9d，小肠移植手术成功率为80％（16／20）。失败原因：静脉血栓1只，失血1只，其他原因2只。结果提示开展的围手术期管理经验经过大量的小肠移植实践取得了较为满意的效果。

Periprocedural management of porcine small intestine transplantation

The experiment was conducted between February 2004 and May 2006 at The Second Affiliated Hospital of Harbin Medical University, Harbin, Heilongjiang province, China. Forty hybrid pigs were used in the experiment, 20 were used as donors and the other 20 were used as recipients. Donor operation: Abdominal aorta was lavaged in situ with 500 mL 4℃ heparinized saline (lavage pressure 7.8-9.8 kPa), intestinal canal cut from donor was conserved in 4℃ physiological saline.Recipient operation: Orthotopic small intestine transplantation and heterotopic small intestine transplantation were conducted according to exploring results, and abdominal cavity was washed with 40-45℃ physiological saline until the flush out liquid became warm.Periprocedural management: Preoperative discussion and postoperative discussion were done, and body temperature of pigs was monitoring and controlled. Early-stage feeding was used, 4 pigs could drink water freely after transplantation and took food normally at the second day, while other 16 pigs began to drink water 2 days after transplantation. Evaluation after the operation: No experimental animal had anastomotic leakage after taking food. Sixteen pigs survived over 7 days, average 9 days, the longest over 14 days. The success rate of the small intestine transplantation is 80% (16/20). Failure reasons: One with phlebothrombesis, one with blood loss and two with unknown reasons. Results showed that experience of periprocedural management had got relatively satisfactory effects through a great quantity of small intestine transplantation practices.
