What is the difference between the traditional two-handed catheter delivery method and the new skill of indwelling needle puncture?

Venous indwelling needle was widely used in Europe and America from 65438 to 0930. In recent ten years, it has been gradually popularized in some Asian countries and regions, and it has also been widely used in clinic in China.

The traditional two-handed delivery method has many disadvantages.

For critically ill patients with traumatic hemorrhagic shock, the degree of blood vessel filling is weaker than that of ordinary patients. Long-term treatment and repeated puncture also increase the difficulty of blood vessel puncture, and the traditional two-handed catheter delivery method is difficult to ensure the success of puncture.

In addition, after the traditional double-hand tube feeding method transfuses blood, the skin at the vein is no longer fixed, resulting in skin relaxation and reduced vascular fixation, which is easy to cause pain to the patient due to the movement of the patient's hands and feet or the limbs of the nursing staff.

Operation method: one-handed tube feeding method (taking right-handed needle insertion as an example). The left hand jumps tightly around the skin at the puncture site, and the right hand holds the indwelling needle for needle insertion. After seeing the blood returning, reduce the needle insertion angle, then slowly enter 0. 1-0.2cm, keep the left hand still, and continue to tighten the skin. Put the index finger of the right hand on the handle of the needle core, and pull the index finger out of the needle core while the thumb sends the hose into the blood vessel. At this time, most of the hose has entered the blood vessel, so you can safely hold the needle handle and send the indwelling needle into the blood vessel completely.

1. Blood returned after the needle was inserted, indicating that the cannula entered the blood vessel.

2. Keep your left hand still and your right hand continue to push the intubation into the blood vessel.

3. Keep your left hand still and pull out the needle core with your right hand.

4. Keep your left hand still, and fix the needle with tape in your right hand, and then proceed to the next operation.
