Infusion port withdrawal process, mainly including disinfection and positioning, anesthesia and incision of the skin to separate the base, remove the infusion tube and check, hemostasis and suture the incision. 1. Disinfection and positioning: infusion port is a medical device mainly used for patients with long-term infusion therapy. Before removal, the area where the infusion port is placed needs to be sterilized, and then the exact location of the infusion port needs to be positioned. 2. Sterilize and incise the skin to separate the base: After locating the port, an incision of about 2 cm in length is usually made to separate the subcutaneous tissue layer by layer to reach the port site. The base of the port is then carefully separated from the surrounding tissue. During the separation process, it is necessary to operate carefully to minimize the damage to the peripheral nerves, blood vessels and other tissues. 3. Remove the infusion tube and check: After separating the base, carefully remove the infusion tube. During the removal process, the integrity of the tubing should be checked to prevent the tubing from breaking off and remaining in the body. 4. Hemostasis and wound closure: After completing the above operations, the process of needle removal is basically completed. Finally, the incision wound should be hemostatized, and then the subcutaneous tissue and skin should be sutured layer by layer, and then the wound should be bandaged.
