The method and time of wearing tourniquet are also learned
在临床实践中发现，在采血过程中应用止血带对血糖含量有一定影响，随机选择40名患者分两组进行实验，对不同止血带结扎法的结果进行比较发现：未扎法（采血中不应用止血带）；常规法（采血中按常规应用止血带，止血带应用时间为 1min）；延长法（采血中延长止血带应用时间，止血带应用时间为 2min），测血标本结果血糖含量有明显区别。
In clinical practice, it was found that the use of tourniquet in the process of blood collection had a certain impact on the blood sugar content. Forty patients were randomly selected and divided into two groups for the experiment. The results of different tourniquet ligation methods were compared and found that: the method without tourniquet was not used in blood collection; Routine method (the tourniquet is used routinely during blood collection, and the application time of tourniquet is 1 min); Prolongation method (prolonging the application time of the tourniquet during blood collection, and the application time of the tourniquet is 2min), the blood glucose content of the blood sample is obviously different.
长时间捆扎止血带静脉极度充盈、压力型线 流水槽模具 景观石 检查井钢模具 保定通风管道 重庆窗帘 隔离墩模具 保定保洁公司增高，可能会造成血管损伤或某些组织因子进入血液，也可能穿刺时相对肿胀的肢体内的组织因子进入注射器内，加快血液凝固使PT缩短。实验证实了捆扎止血带时间过长（超过3min以上）PT缩短。
If the tourniquet is tied for a long time, the vein is extremely full and the pressure is increased, which may cause vascular damage or some tissue factors enter the blood, or tissue factors in the relatively swollen limbs enter the syringe during puncture, speeding up blood coagulation and shortening PT. The experiment confirmed that the binding time of tourniquet is too long (more than 3min) and PT is shortened.
