Effect and Ethical Consideration on New Technical Application of Negative Pressure Wound Therapy / 中国医学伦理学

ABSTRACT

Objective:To explore the clinical effect of negative pressure wound therapy and to discuss the ethi-cal issues in this therapy and seek a solution. Methods:Sixty patients with negative pressure wound therapy in our hospital were invited to participate in this study. Patients were all with deep pressure ulcers or diabetic foot, of which the Wagner Scores were graded as three or four. They were divided into two groups randomly. The subjects in control group received standard treatment, while those in experimental group were treated by self -designed closed negative pressure drainage settings. The wound healing time, the cost of the treatment and comfort were compared between the two groups. Results:The cost of wound care in the experimental group was less than those in the control group (P0. 05). But the wound healing time was longer in the experimental group than those in the control group. Conclusion:Self-designed closed negative pressure settings can decrease the cost of patient care with the equal patient comfort and acceptance as the standard negative pressure, however, the wound healing time has been extended. So before using negative pressure technique, the medical staff should comprehensively analyze, be guided by medical ethics and choose the appropriate treatment for different patients.
