1) When performing indwelling needle puncture on patients, try to avoid joint areas as much as possible.
2) After puncture, all catheters should be inserted into the blood vessels.
3) Keep the skin at the puncture site clean and dry for easy fixation. Before puncture, it is not advisable to use too much iodine to avoid stimulating blood vessels.
4) Maintaining the indwelling needle requires frequent observation and immediate fixation. If there is sweat causing the film to curl, it is still necessary to replace it immediately to prevent infection.
5) Strengthen relevant health education for patients and their families. Teach patients the necessary knowledge for maintenance and ensure seamless management.
6) After puncture, the catheter should be firmly fixed. The application should be firmly fixed, and the movement of the trocar should be reduced during puncture.
