Can Hydrocolloid Dressings Cause Side Effects?

Hydrocolloid dressing is one of the most commonly used advanced dressings, which is widely used in clinical wound treatment and also in daily life, such as hydrocolloid bandages for small wound care, such as acne. However, it does not mean that people have a deep understanding of it.

Is hydrocolloid dressing safe?

The application of hydrocolloid dressing has been more than 20 years, and its safety is high, with few reports related to allergic contact dermatitis. However, some types of hydrocolloid dressings contain hydrogenated rosin ester as a thickening agent, which has the risk of causing allergies. Therefore, when using hydrocolloid dressings, it is best to understand the composition of the product. Due to the weak absorption of hydrocolloid dressing to exudate, if used for wounds with a large amount of exudate, it may cause skin saturation, and if used for wounds with infection risk, it may accelerate the occurrence of infection.

In addition, due to the strong viscosity of hydrocolloid dressing, its viscosity will only decrease after absorbing enough exudate. If it is used for too short a time, it may cause skin and wound damage when removing the dressing, especially for new granulation tissue and epithelium which are relatively fragile. Therefore, the time of using hydrocolloid dressing should not be too short and should follow the manufacturer's recommendations. In clinical practice, it is common to remove the dressing after a short period of time without understanding the characteristics of hydrocolloid dressing. For example, during perioperative pressure ulcer prevention, due to the strong stickiness of the dressing, skin damage was caused when removing the dressing. Especially for elderly patients, due to dry and fragile skin, dressing replacement or removal may cause damage. Therefore, special attention is required when using hydrocolloid dressings for pressure ulcer prevention or venous thrombosis treatment. In addition, when removing hydrocolloid dressings, do not pull hard, but press one side of the dressing with one hand, while stretching and lifting the dressing to slowly tear it off.

How much liquid can hydrocolloid dressing absorb?

The liquid absorption capacity of hydrocolloid dressing varies greatly between different products, and is closely related to the length of its use. Laboratory studies have shown that hydrocolloid dressings are not suitable for wounds with moderate to high exudate. Other studies have shown that if used properly, hydrocolloid dressings can reduce wound exudate. Essentially, as one of wound plaster types, hydrocolloid dressing is a moisturizing dressing that maintains a moist environment after absorbing and locking exudate, with moderate liquid absorption capacity and is only suitable for low to moderate exudate wounds.
