The application of intravenous I.V. Catheters is a better method of clinical infusion. Venous I.V. Catheters are easy to operate and are suitable for puncture of any part. At the same time, it alleviates the pain of repeated punctures and reduces the workload of nursing staff.
Precautions for use:
(1) When using intravenous I.V. Catheters, the operating procedures of the aseptic technique must be strictly followed.
(2) Closely observe the changes and local conditions of the patient's vital signs. Before and after each infusion, check the puncture site and vein direction for redness and swelling, and ask the patient for pain and discomfort. If there is any abnormality, the catheter should be taken out in time and dealt with accordingly. For patients who still need infusion, their limbs should be replaced and punctured.
(3) The limbs using intravenous I.V. Catheters should be properly fixed, and the movement of the limbs should be minimized to avoid being wetted by water. If you need to wash your face or take a shower, wrap the parts in the plastic paper. For patients who can move downwards, avoid leaving the vein I.V. Catheters in the lower extremities, so as not to return blood due to gravity and block the catheter.
(4) Before each infusion, the blood should be drawn back, and then the catheter should be flushed with sterile 0.9% sodium chloride injection. If there is no return of blood and resistance to flushing, the I.V. Catheter should be considered to block the catheter. At this time, the intravenous I.V. Catheters should be pulled out. Remember not to push hard with the syringe, so as not to push the clotted thrombus into the blood vessel and cause an embolism.
