Detained needle vein is a better method of clinical infusion, on the one hand, can reduce the pain caused by repeated puncture of scalp needles and can be suitable for long-term infusion of adults.On the other hand, it also reduces the workload of clinical nurses.
Detained needle vein is simple, suitable for any part of the puncture, reduces the patient repeatedly puncture pain, reduce the workload of nurses, nurses and patients in clinic by the welcome.But the indwelling time has been controversial, the administrative department of health, hospital infection and catheter indwelling time that manufacturers should not be more than 3-5 days.
 
Operation
1, WIth to the patient bed, on the bed number, name, explain to the patient.
2,The transfusion bottle is hung on an infusion rack, open catheter needle packing, wearing gloves.
3, Selection of blood vessels.Tie cuff in the puncture point above 10cm, the local skin disinfection routine, to be dry.
4, Remove the needle, remove the needle sleeve, rotating the needle of the needle bevel to heart.The prepared vein infusion scalp needle into heparin cap, pay attention to exhaust air, closed infusion switch.
5, The needle and the skin was 15 ~ 30 degrees angle of puncture, see back to the blood, then reduce the angle of puncture needle puncture advance 0.2 ~ 0.5cm.Ask the patient to make a fist, the left wing to tighten the skin, right hand thumb and index finger clamping catheter needle.Right hand fixed catheter needle, left hand to pull out the needle core is 0.5 ~ 1cm, the left hand will coat all the tube into the vein, loose pressure pulse band, enjoin patient loose fist.
6, Pull out the needle, with special applicator fixed catheter needle, written in the applicator on the date and time of indwelling the patient's name, then, fixed heparin cap, remove the cuff.
7, Take off the gloves again, check the correct, recording time, drop speed in the infusion and signature card.According to the doctor's condition and adjusting the speed of infusion (reference intravenous infusion)
8, help the patients lie in comfortable position, the bed unit, by intradermal injection processing, hand washing.
9, attention to patients.According to the situation of health education.
10, sealing:When the sealing liquid after transmission.
The routine disinfection of heparin cap.
The pumping tube sealing solution (saline and heparin saline) syringe needle into the heparin cap.
(heparin solution preparation concentration:1.25 million U of a heparin dilution in 125 to 1250mL saline, namely each ml containing 10 to 100u heparin and dose 5ml, strict control of sealing liquid in the maintain time, maintain the normal physiological saline in 6 to 8 hours, the diluted heparin solution maintained for 12 hours).
The injection side sealing liquid side needle.
The indwelling needle used to clamp the silicone tube folder.
11, once again infusion.
The routine disinfection of heparin cap:Loosen the clamp, the pumping syringe needle has the physiological saline into heparin cap, pulling back the blood, then injecting 5 ~ 10mL saline.
Then the infusion of scalp acupuncture into the heparin cap, open the regulator again infusion dripping speed.
The observation of the puncture site has no swelling, in complete dressing surface along the duct have no tenderness to touch.
Note editor
1, the use of intravenous indwelling needle, it is necessary to strictly implement the aseptic technology operation procedures.
2, close observation of the patient's vital signs and the changes of local conditions.Before and after each infusion, the puncture site and the direction of the vein should be checked and there was no swelling, and asked if the patient had pain and discomfort.If there is any abnormal situation, the catheter should be removed in time and make the corresponding treatment.For still need to be replaced with the infusion of the body to be further.
3, the use of venous indwelling needle body should be properly fixed, reduce physical activity, avoid being wet with water.If you need to wash your face or take a bath when the application of plastic paper will be part of the parcel.Patients who are able to lower the activity, the intravenous indwelling needle avoid retained in the lower limb, so as not to cause the gravity of blood back to the blockage of the catheter.
4, before each infusion pump blood, and then sterile saline irrigation catheter.If there is no return to blood, flushing resistance, should consider retaining needle catheter blocking, at this time should be pulled out of the venous indwelling needle, remember not to use the syringe to push hard, so as to prevent the solidification of the thrombus to promote blood vessels, causing embolism.
