Patients may experience some discomfort when using polyurethane foam dressings, but usually these discomforts are mild and temporary. Here are some possible discomforts:
Mild itching or stinging: Patients may experience mild itching or stinging due to the contact of the polyurethane foam dressing with the wound. This is usually caused by the dressing rubbing against the wound surface or the skin being sensitive to certain components of the dressing.
Skin tightness: Polyurethane foam dressings have certain elasticity and conformability, and sometimes patients may feel skin tightness. This tightness is usually due to the pressure of the dressing as it fits the wound, but will generally lessen as the wound heals.
Changes in temperature sensation: After using polyurethane foam dressing, some patients may feel a change in the temperature of the wound site, such as feeling slightly warm or cool. This may be due to the insulating or cooling effect of the dressing on the wound environment, but generally does not cause a serious problem.
Allergic reactions: Although polyurethane foam dressings generally have good biocompatibility, individual patients may still have allergic reactions to certain components of the dressing, manifesting as skin redness, swelling, itching and other symptoms. If this occurs, discontinue use immediately and consult a physician.
If obvious discomfort or abnormal symptoms occur, you should consult a doctor in time to receive appropriate treatment and advice.
