Clinical Use
1) Place the patient in a trendelenberg position (15 to 30 degrees head down) to reduce the chance of an air embolism, turn the patient’s head to the side contralateral to the site chosen.
2) mark puncture site
3) Anesthetize the spot by using needle, the angle between needle and skin shall be 30 to 45 degrees.
4) when a flush of blood returns by advancing the needle, insert venous needle.
Remarks: pay attention to the direction of needle and color of blood
returns during advancing seeker needle , meanwhile, pay attention to
the direction of needle and depth of puncturing needle , the bevel of
needle shall be faceup.
5) one hand hold the needle,another hand hold the syringe ,keep the pressure negative during the slow insertion. When you feel the needle placed into the vein, the blood will return smoothly.
6) Guidewire will be inserted through Y shaped syringe or hollow syringe.
Remarks: during the insertion of guidewire,please judge the resistence , don’t withdraw
the guidewire by force, withdraw the guidewire together with syringe if ncessary.
7) withdraw syringe, and insert dilator by 1-2 cm under the skin for enlarge the track.
Remarks: During insertion of dilator, attention shall be paid to the direction and the force of dilator, specially the force transfering between dilator and guidewire, the driving force shall be increased gradually.
Withdraw the dilator, implant the catheter from the end of guidewire, and saline shall be injected into to the catheter immediately.
Ensure the whole catheter implanted completely and then fixed the catheter at the final position.
Connect with other tubes and devices
The force for inserting the catheter is related to enlarging of the track, if the resistence is big, the length of each insertion shall be shorter , and attetion shall be paid to avoid kink of guidewire.
