[Efficacy of wound dressing with microspheres containing levofloxacin on burns treatment]
Abstract:
This research was aimed to find the skin irritation and burns treatment effect of wound dressing with mi- crospheres containing levofloxacin. We used reference GB/T16886. 10-2005 to evaluate the dressing skin irritation. We prepared rabbit models divided into three groups. The control group was rapped with Vaseline gauze bandage, while the positive control group was rapped with the wounds of nano-silver paste bandage. The experimental sample group was rapped with wound dressing with microspheres containing levofloxacin. We measured the wound without healing area and the hydroxyproline content at the ends of 3 d, 6 d, 9 d, 14 d, 21 d, 28 d. and meanwhile performed histopathological examination. The experimental results showed that the dressing primary irritation index was 0. The nonhealing wound area of theexperimental sample group and positive control group at the ends of 6 d, 9 d, 14 d, 21 d were less than that of the control group (P<0. 05). The nonhealing wound area of the experimental sample group at the ends of 9 d and 14 d was significantly lower than that of the positive control group (P < 0.05). The hydroxyproline content of the experimental sample group at the ends of 6 d, 9 d and 14 d was significantly higher than that of the positive control group and blank control group (P<0. 05). The pathology observed of the experimental sample group at 21 d were the earliest appendages. The wound dressing with microspheres containing levofloxacin has minimal skin irritation, effectively promote wound healing of burn.
Insights
Levofloxacin-loaded microsphere wound dressings show minimal skin irritation and effectively promote burn wound healing. This advanced dressing significantly reduces healing time compared to traditional treatments.
Area of Science:
- Biomaterials Science
- Wound Healing Research
- Dermatology
Background:
- Effective burn wound treatment is crucial for patient recovery and minimizing complications.
- Current treatments may have limitations in efficacy or side effects.
- Levofloxacin is a potent antibiotic with potential for wound healing applications.
Purpose of the Study:
- To evaluate the efficacy of wound dressing with microspheres containing levofloxacin for treating skin irritation and burns.
- To assess the skin irritation potential of the novel wound dressing.
- To compare the healing effects of the levofloxacin microsphere dressing against control groups.
Main Methods:
- Skin irritation was assessed using the GB/T16886.10-2005 standard in rabbit models.
- Three groups were established: control (Vaseline gauze), positive control (nano-silver paste), and experimental (levofloxacin microspheres).
- Wound healing was monitored by measuring non-healing area and hydroxyproline content, with histopathological examinations performed.
Main Results:
- The levofloxacin microsphere dressing exhibited a primary irritation index of 0.
- The experimental and positive control groups showed significantly reduced non-healing wound areas compared to the control group.
- The experimental group demonstrated significantly faster healing and higher hydroxyproline content than the positive control group.
Conclusions:
- Wound dressing with levofloxacin-loaded microspheres demonstrates minimal skin irritation.
- This novel dressing effectively promotes burn wound healing, outperforming nano-silver paste.
- The findings support the use of levofloxacin microspheres as a promising therapeutic option for burn wound management.
