Introduction
Failure to seal the infusion port with heparin may lead to blockage. An infusion port refers to the site where the intravenous catheter connects to the needle during injection, typically made of rubber or silicone. Heparin is an anticoagulant commonly used to prevent and treat thrombotic disorders. During infusion, if the infusion port is not properly sealed, heparin may contribute to clot formation within the infusion tubing, leading to occlusion.
Failure to flush the infusion port with heparin may generally lead to blockage.
An infusion port refers to the site where an intravenous catheter connects to tubing and needles during injection, typically made of rubber or silicone. Heparin is an anticoagulant commonly used to prevent and treat thrombotic conditions. During infusion, if the infusion port is not properly flushed and sealed, heparin may contribute to clot formation within the infusion line, leading to occlusion. Similarly, for indwelling needle infusion lines, failure to flush and seal the line after use may also result in blockage.
To prevent catheter occlusion, it is standard practice to disinfect the infusion port before and after infusion and promptly flush and seal the port upon completion of infusion. If medication needs to be added during infusion, the drug should first be dissolved in an appropriate solvent and then injected into the infusion line via a syringe, rather than being injected directly into the infusion port.
In addition, to ensure the safety and effectiveness of infusion therapy, it is essential to strictly follow medical instructions and established procedures, using the infusion port and medications correctly. This helps effectively prevent complications such as infection and drug leakage, thereby enhancing the safety and efficacy of infusion treatment.
