Jamieson等近年实验研究表明,在肠缺血时血清和腹腔液中磷酸盐水平有显著和早期升高。本实验研究是试图进一步证实这一升高是否确实为早期和可靠诊断的指标,并确定这种升高与肠活力和肠系膜血流重建之间的关系。材料和方法取体重10～20公斤的狗,进行气管插管麻醉。作右股动脉插管以备采血标本之用。用5％葡萄糖生理盐水以每小时10 ml/kg注入下肢周围静脉。在腹正中作切口手术。实验分6组进行,每组5条狗。第一组为对照组,剖腹后解剖从腹主动脉分出的肠系膜上动脉的起始部,但不予结扎。其余5组为实验组,均将肠系膜上
Recent experimental studies by Jamieson et al. Showed that there was a significant and early increase in phosphate levels in serum and peritoneal fluid during intestinal ischemia. This experimental study is an attempt to further confirm whether this elevation is indeed an indicator of early and reliable diagnosis and to determine the relationship between this increase and intestinal motility and mesenteric blood flow reconstruction. Materials and methods Take dogs weighing 10 ~ 20 kg, intubation anesthesia. For the right femoral artery catheter preparation for blood samples. Peripheral limbs were infused with 5% dextrose saline at a rate of 10 ml / kg per hour. In the middle abdominal incision surgery. The experiment was divided into 6 groups, each group of 5 dogs. The first group was the control group. After laparotomy, the beginning of the superior mesenteric artery separated from the abdominal aorta was dissected, but no ligation was performed. The remaining five groups for the experimental group, will be on the mesentery
