Introduction
In general, an intravenous injection site (commonly referred to as a "drip needle puncture") may become swollen. Swelling can be managed by discontinuing infusion at the affected site, applying pressure, using warm compresses, administering medications to reduce swelling, or performing incision and drainage if necessary. If swelling or a lump develops at the injection site during infusion, the infusion should be stopped immediately, or the medication should be administered through a new puncture site to prevent ineffective drug delivery and extensive swelling at the original site.
In general, a swollen intravenous injection site (commonly referred to as a "drip needle site") usually results from intravenous infusion. Swelling at the IV site can be managed through measures such as stopping the infusion at the affected site, applying pressure, warm compresses, medication for reducing swelling, or incision and drainage. Specific approaches are analyzed below:
1. Stop Infusion at the Affected Site
If swelling occurs at the injection site during infusion, the infusion should be stopped immediately or restarted at a different site to prevent ineffective drug delivery and extensive swelling at the puncture area.
2. Pressure Application
For minor swelling, gentle pressure can be applied to the puncture site while maintaining a resting position and avoiding arm dangling, which helps facilitate self-absorption of the swelling.
3. Warm Compress
If the swelling has not been absorbed within 72 hours, a warm towel can be applied to the affected area to improve local blood circulation, promote absorption and dissipation of edema, and relieve discomfort caused by swelling.
4. Medication for Reducing Swelling
When local swelling is significant and the above methods are ineffective, topical medications such as sodium aescinate gel or Voltaren ointment may be used as directed by a physician.
5. Incision and Drainage
For patients with abscess formation, surgical incision and drainage are required. With prompt treatment, the swollen area can be rapidly absorbed and relieved.
Swelling caused by intravenous injection should be evaluated and treated by a healthcare professional based on the specific medication and condition; self-medication is not recommended.
