Introduction
Venous catheter occlusion can be classified into thrombotic and non-thrombotic types. When a venous catheter becomes blocked, it is first necessary to determine the nature of the obstructing material. Then, flush the clamped catheter with 0.9% sodium chloride injection solution containing heparin sodium and urokinase, and use a syringe to aspirate backward and withdraw the clot. It is recommended that venous catheter occlusion be managed under the guidance of a physician.
Blocked intravenous indwelling catheters can be classified into thrombotic occlusion and non-thrombotic occlusion. It is recommended to manage blocked intravenous indwelling catheters under medical guidance. Taking thrombotic occlusion as an example, the specific procedures are as follows:
1. Determine the type and nature of the obstructing material based on the cause of the catheter blockage.
2. Use 10 mL of 0.9% sodium chloride injection containing either 25 U/mL heparin sodium or 100,000 U/mL urokinase to flush the clamp, diluting for approximately 5 minutes.
3. Gently aspirate with a 10 mL empty syringe to draw the clot out from the catheter.
4. If no blood return is observed, repeat the procedure once. If there is still no blood return, remove the catheter immediately.
Sterile technique must be strictly followed when placing an intravenous indwelling catheter. Avoid catheter bending to prevent adverse symptoms.
