Management of Blistering Stretch Marks
For blistering stretch marks, the recommended treatment is to gently pierce the blister at its base with a sterile needle, leave the blister roof intact as a biological dressing, and apply a bland emollient to support barrier function and encourage re-epithelialization. 1
Initial Management of Blisters
- Gently cleanse the blister with an antimicrobial solution, taking care not to rupture it 1
- Pierce the blister at its base using a sterile needle with the bevel facing up, selecting a site that allows fluid to drain out by gravity 1, 2
- Apply gentle pressure with sterile gauze swabs to facilitate drainage and absorb fluid 1
- Do not remove the blister roof as it acts as a biological dressing and protects the underlying skin 1
- After drainage, gently cleanse again with an antimicrobial solution 1
- Apply a bland emollient such as 50% white soft paraffin and 50% liquid paraffin to support barrier function and reduce transcutaneous water loss 1, 2
Prevention and Management of Complications
- Monitor for signs of infection, which is a significant risk in any open skin lesion 1
- Consider daily washing with an antibacterial product to decrease bacterial colonization 1
- Change dressings using aseptic technique to prevent contamination 1
- If clinical signs of infection develop, obtain bacterial and viral swabs of the affected area 1
- Consider short-term application of topical antimicrobials if appropriate 1, 3
- Use systemic antibiotics only if there are local or systemic signs of infection 1
Pain Management
- Many patients report pain or burning sensation during blister care; offer analgesia prior to the procedure 1
- Pay attention to both acute and background pain management, especially during dressing changes 1
- Consider consulting a pain management team if pain is difficult to control 1
Additional Care Measures
- For large blisters, a larger needle may be needed, and multiple piercing sites might be required to ensure proper drainage 1
- If necessary, apply a non-adherent dressing over the area to protect it 1, 2
- Document the number and location of blisters to track progression of the condition 1, 4
- For extensive areas, consider antiseptic baths to help dry lesions and prevent infection 2
Special Considerations for Stretch Marks
- Unlike typical stretch marks (striae distensae), which are usually asymptomatic, blistering stretch marks require prompt intervention to prevent complications 5
- The underlying pathophysiology of blistering in stretch marks is not well understood, but treatment principles follow those of other blistering conditions 5, 6
- After the acute blistering phase resolves, consider addressing the underlying stretch mark with appropriate treatments 5
By following these guidelines, you can effectively manage blistering stretch marks while minimizing the risk of complications such as infection and scarring.
