How Many Days Should a Wound Dressing Stay On? Change Guide
How many days should a wound dressing stay on?
The Quick Answer
Dressing duration depends on **type and exudate level**: Xeroform/petrolatum gauze (daily), hydrocolloid (3–7 days), hydrogel (2–3 days), alginate (5–7 days). Never exceed manufacturer guidelines. Critical rule: change immediately if saturated, soiled, or causing skin irritation—prolonged wear risks maceration, infection, or adherence trauma that resets healing progress by days to weeks.
Why We Ask This
Patients extend dressing wear beyond recommendations to reduce discomfort or costs, unaware that 'more coverage' paradoxically harms healing through moisture imbalance—maceration in exuding wounds or desiccation in dry wounds both delaying epithelialization despite good intentions.
The Practical Science
Optimal wear time balances moisture maintenance with bioburden control. Bacterial counts double every 20 minutes in warm, moist environments—exceeding 10⁵ CFU/g (infection threshold) within 48 hours in unchanging dressings on moderate-exudate wounds. Daily changes disrupt this exponential growth curve.
In Clinical Practice
A surgical incision with light serous drainage receives daily Xeroform changes for 7 days until epithelialization completes. The same wound developing increased exudate at day 4 requires twice-daily changes until drainage decreases—demonstrating how dynamic assessment must guide frequency rather than rigid schedules.
