Abstract
Pressure injury (PI) is a worldwide health problem that has attracted widespread attention from scientific and clinical research communities. PI incidence correlates with the increase of the aging population. In this situation, it is crucial to select effective and affordable drugs for patients and healthcare systems. Herein, we report a case of a 94-year-old female with a stage 2 PI wound, which was treated topically using a novel combination of mixed powders: metronidazole and nano pearl powders. Metronidazole is the preferred option to treat infected wounds due to its excellent antibacterial ability. However, some drawbacks have limited the use of metronidazole in PI wound management, such as its poor capacity to accelerate wound closure. Pearl powder has a strong capacity to promote wound healing and closure but has not been effective at resisting wound infection. To take advantage of powdered drugs' wound treatment properties and accelerate PI wound healing, we prepared powdered mixtures for wound application. Both drugs are cost-effective and were beneficial to wound healing. Therefore, the combination of metronidazole and pearl powders offer a promising choice to patients with PI wounds.
