ABSTRACT

PURPOSE: Paediatric burn care is a delicate discipline which benefits from special attention. Despite being highly effective, the current standard of care for second degree burns in the largest paediatric burn center in France - exposure to infrared light - involves long hospital stays, straining economic and professional resources, especially in times of a pandemic. The present study investigated this standard of care and compared it to the use of a bacterial nanocellulose dressing. MATERIALS AND METHODS: A retrospective analysis of two groups has been performed: the control group assessed thirty consecutive children treated with the standard of care, and the intervention group assessed thirty consecutive children treated with the bacterial nanocellulose dressing. Parameters evaluated were: healed wounds, additional treatments, rate of infections, hospital length of stay, pain experience and overall satisfaction. RESULTS: The two groups did not differ significantly in terms of age and TBSA. A significant reduction in hospital length of stay (p < .001) and pain experience (p < .001) could be observed. In terms of healed wounds, additional treatments and infections, the two groups were equally matched (p > .05) with satisfactory results in both groups. Tendencies towards better results could be seen in the intervention group. CONCLUSION: The use of bacterial nanocellulose wound dressings is an important tool in the armamentarium of today's burn surgeons. Satisfying results were achieved, ameliorating burn care for children. Future studies are indicated to further support its value and assess the economic impact.

ABSTRACT

PURPOSE: Modern burn care strives for new means to guarantee optimised wound healing. Several studies have shown a correlation between the pH value in a (burn) wound and successful wound healing. A multitude of devices to monitor pH is available, all requiring direct wound contact and removal of the dressing for pH monitoring. The aim of this feasibility study was to create a sterile and easy to handle method for pH monitoring while simultaneously using an advanced wound dressing. MATERIALS AND METHODS: Dressing sheets of biotechnologically generated nanofibrillar cellulose (epicitehydro) were chemically functionalised with the indicator dye GJM-534. pH-donors with increasing pH were subsequently applied to the created indicator dressing. To investigate temporal resolution and continuous monitoring we used circular pH-donors with different pH (7 and 10) and decreasing diameters that were placed on another dressing sheet. Clinically relevant spatial resolution was checked by a wound bed simulation with small areas (8 mm) of higher pH (10) on a field of lower pH (7) and vice versa. RESULTS: The indicator dressing showed a gradual colouring from yellow to dark orange with increasing pH in steps of 0.3. After conversion of digital pictures to greyscale values, a sigmoidal distribution with a pKa-value of 8.4 was obtained. A ring-like pattern with alternating colour change corresponding to the pH was observed in the continuous monitoring experiment and the wound bed simulation delivered excellent local resolution. CONCLUSION: Since the pH of a (burn) wound can have a significant influence on wound healing, a pH indicator was successfully linked to an advanced, temporary, alloplastic wound dressing material. We were able to show the possibility of pH monitoring by the dressing itself. Additional testing, including studies with large case numbers for optimisation are necessary before clinical implementation.
