Low-cost negative pressure wound therapy for gunshot traumatism in developing countries

Area of Science:

• Trauma Surgery
• Wound Management
• Plastic Surgery

Background:

• Gunshot and explosive wounds often result in significant tissue loss and contamination.
• Achieving adequate wound coverage is a primary surgical challenge in these cases.
• Traditional treatments like sugar and honey dressings have limitations in managing complex wounds.

Purpose of the Study:

• To evaluate the efficacy of vacuum-assisted closure (VAC) therapy for complex traumatic wounds.
• To compare VAC therapy outcomes with conventional wound care methods.
• To demonstrate the feasibility and benefits of VAC therapy in developing countries.

Main Methods:

• Application of vacuum-assisted closure (VAC) therapy in a humid environment.
• Monitoring of exudate drainage, local blood flow, and tissue edema.
• Assessment of bacterial colonization and granulation tissue formation.
• Presentation of four clinical case observations.

Main Results:

• VAC therapy demonstrated superior outcomes compared to sugar and honey dressings.
• Enhanced local blood flow through neoangiogenesis and stimulated cell proliferation.
• Reduced bacterial colonization and tissue edema, promoting granulation tissue.
• Successful wound healing and coverage achieved in presented cases.

Conclusions:

• Vacuum-assisted closure (VAC) therapy is a feasible and beneficial treatment for complex traumatic wounds.
• VAC therapy promotes wound healing by managing exudates, increasing blood flow, and reducing bacterial load.
• This approach offers a viable solution for wound management in resource-limited settings.
