Improvement medicine function experiment median artery intubation experimental study
And uses the straight leaving alone needle compared with the traditional self-restraint's arterial cannula to replace the arterial cannula in the medicine function experiment the application situation, discovers one kind to be advantageous for the student to operate, the success ratio high arterial cannula method. Method: Divides into A group and B group stochastically 40 example experimental animal, uses the traditional self-restraint separately the arterial cannula and makes the arterial cannula good arteria carotis communis anterior encheiresis with 18G×29MM the model straight vein leaving alone needle, and carries on the comparison and the appraisal to 2 group of intubation method's surgery time and the success ratio. Finally: Makes the arterial cannula 2 groups of comparisons with the traditional self-restraint's arterial cannula and with the straight leaving alone needle, the straight leaving alone needle makes the arterial cannula method in the surgery time and the intubation success ratio to be higher than traditional obviously the arterial cannula method. Conclusion: The straight leaving alone needle makes the arterial cannula and the traditional self-restraint arterial cannula compares has simple, fast, accurate, the security and the success ratio higher merit. Replaced the tradition arterial cannula with the straight leaving alone needle the biggest superiority is solves the self-restraint arterial cannula caliber size to vary, not to have the fixed point reasonably, but easy to fall off and so on questions, was worth promoting.
