When using closed intravenous infusion to treat physical disorders, it is first necessary to ensure the sterility of the infusion environment. Additionally, before initiating the infusion, allergy tests should be conducted for certain drugs that may potentially cause allergic reactions in the body, in order to avoid potential health hazards resulting from improper medication. Furthermore, during the infusion process, it is important to minimize excessive movement at the infusion site to prevent needle dislodgment or other such occurrences. The key considerations primarily include the following:

Key Considerations for Closed Intravenous Infusion

1. Ensure that the operation is performed in a sterile environment, and have a clear understanding of the relevant procedures, regulations, and requirements.

2. Be aware of contraindications and incompatibilities between drugs. For drugs with strong irritancy or special characteristics, medication should be added only after the needle has entered the blood vessel.

3. Have a thorough understanding of the patient's condition and arrange the infusion sequence clearly to enhance treatment effectiveness.

4. During the patient's use of closed intravenous infusion, it is important to strengthen patrols and closely observe the infusion status. Check for any leakage in the needle and infusion tubing, needle dislodgment, blockage, or displacement, as well as any distortion or compression of the infusion tubing. Additionally, monitor for any swelling or pain at the infusion site.

5. When using closed intravenous infusion, it is crucial to explain the purpose of the infusion to the patient. Advise them to keep the liquid level higher than the infusion limb to prevent needle dislodgment. Furthermore, remind patients not to adjust the infusion speed themselves.
