OBJECTIVE In order to reduce the damage of negative pressure from cardiotomy suction on red blood cell and endocardium during extracorporeal circulation, we developed a cardiotomy suction relief valve and applied clinically.

作者：乔建民，高立兵，王委三目的为了减轻体外循环心内吸引力过大，所产生的负压对红细胞和心内膜的破坏，将研制的一种心内吸引减压阀我们在临床试用。

Application of cardiotomy suction relief valve reduces the negative pressure of cardiotomy suction, consequently prevents endocardium and red blood cell from hematoclasis and endocardium damage.

心内吸引减压阀可减小体外循环心内吸引管内的负压，减轻红细胞破坏和心内膜伤害，有保护心内膜以及红细胞的作用。

Results:The clinical manifestation of postoperative gastroparesis was abdominal distention,vomit,no obvious celiodynia and normal gas discharge by anus in majority patients,weak enterocinsia was shown by barium meal X-ray of alimentary canal opacification,and unobstructed anastomotic stoma shown by gastroscopy.52 patients relieved from gastrointestinal decompression,nutrition support,water-electrolyte metabolism balance,gastrointestinal motility medicine and combined integrated traditional chinese medicine and western medicien treament.

结果：术后胃瘫的临床表现主要为腹胀、呕吐、无明显腹痛，大多数患者排气正常，消化道X-ray钡餐造影提示胃蠕动差，胃镜检查吻合口通畅。52例患者进行胃肠减压、营养支持、维持水电解质代谢平衡治疗，并应用促进胃肠蠕动的药物及中西医结合治疗等非手术治疗后，均缓解。
