Use of medium and long catheters for PVC infusionUse of medium and long catheters for PVC infusion
1. What is a medium and long catheter?
The medium and long catheter is a vascular access device through a thicker vein on the arm. It is mainly used for medium and short-term infusion therapy with a treatment time of more than 7 days. The tip of the catheter is located at the level of the axilla.
2. What are the benefits of medium and long catheters?
(1) Complete inpatient intravenous treatment with "one shot";
(2) Protect blood vessels and avoid the pain of repeated puncture;
(3) Prevent drug extravasation;
(4) The catheter has a high success rate, safe use, low infection rate, and fewer complications; because it is guided by B-ultrasound.
(5) The catheter can be indwelled for up to 7 weeks;
(6) Irritable limbs are not affected;
(7) Ensure an effective vascular access to facilitate timely medication and rescue medication;
(8) Simple nursing care, reducing the total treatment cost;
(9) The peripheral blood vessels are poor and it is difficult to get an injection;
(10) There is no sequelae after extubation.
3. When or what crowd
Need to place a medium and long catheter?
(1) When you need short-term intravenous infusion (more than 5 days);
(2) (Such as mannitol, 10% potassium chloride, 10% sodium chloride);
(3) When you need intravenous infusion during the day and night;
(4) When you are in a critical condition (such as coma, irritability).
4. What should I pay attention to after inserting a medium and long catheter?
(1) Reflect the condition of the body and the limbs on the side of the puncture to the nurse truthfully;

(7) Do not pull the catheter or change the position of the catheter at will;
(8) The arm with the tube should not use excessive force and lift heavy objects.
5. What are the contraindications for medium and long catheters?
(1) Infusion of blister drugs, medium and long catheters are not useful.
(2) History of thrombosis, hypercoagulability, reduced limb venous blood flow, and end-stage renal disease.
(3) Blood vessel sclerosis and phlebitis.
6. Medium and long catheters are used in your hospital. What impact do you think this new technology has brought?
The guidelines recommend the principles of infusion:
Meet the needs of infusion therapy.
The number of punctures is the smallest.
The retention time is the longest.
Minimal damage to the patient.
The risk is minimal.
For patients, reduce repeated punctures, reduce the risk of drug extravasation, and improve satisfaction.
For nurses, reduce the workload of nurses and reduce the risk of professional sharp equipment.
