Abstract
INTRODUCTION AND IMPORTANCE: Following debridement, the skin and mucous membranes around the wound must be disinfected with broad-spectrum disinfectants like Iodophor, 75 % ethanol, chlorhexidine, and bromogeramine. Despite the fact that it is rarely reported, skin allergy to disinfectants is extremely detrimental to wound recovery after debridement. CASE PRESENTATION: In this study, a 29-year-old man with no previous allergic history developed delayed contact dermatitis after being exposed to multiple disinfectants, including iodophor, 75 % ethanol, and Erythromycin ointment. Given the possibility of the patient's allergic constitution, skin patch tests were repeated to confirm the allergic disinfectants. To avoid the allergy, the wound was simply rinsed with 0.9 % sodium chloride solution and Cefdinir (0.1 g, tid) was taken orally, while all local disinfectants were discontinued. The wound healing process was gradually accelerated, and allergic symptoms were alleviated. Furthermore, our findings revealed that the frequency and immunosuppressive function of Tregs were significantly lower in patients than in healthy controls (P < 0.05). CLINICAL DISCUSSION: By minimizing allergic reactions and providing appropriate wound care, the use of 0.9 % sodium chloride solution with oral antibiotics could expedite the healing process. This enabled the wound to close faster and reduces the risk of complications. CONCLUSION: The use of 0.9 % sodium chloride solution for wound irrigation, combined with oral administration of antibiotics, could be modified to mitigate further allergic reactions and enhance the recovery process following debridement. However, individual patient characteristics and medical history should also be taken into consideration when making these alterations.
