Comparative study in patients treated by negative pressure wound therapy versus conventional wound treatment for abdominal wounds

Abstract

Background: The use of negative pressure to enhance wound healing is a well-known notion. If excess fluid is not effectively evacuated from a wound during surgery, its constituents may act as both physical and chemical impediments to wound healing. Furthermore, mechanical stresses can alter tissue form and growth. A buried drain tube has little mechanical impact on the surrounding tissue. Aims and Objectives: The aim of the study was to compare the effectiveness of negative pressure wound therapy (NPWT) versus conventional wound treatment (CWT) in abdominal wounds after surgery in clinical practice. Materials and Methods: The present and prospective study was conducted among 60 patients taking treatment for abdominal wounds after surgery at General surgery Department at BJ Medical College, Ahmedabad, Gujarat, India, during June 2022–May 2023. The cases divided in two groups: Group A: Patients treated with NPWT (n = 30), Group B: Patients treated with CWT (n = 30). Results: Cases treated by NPWT had faster reduction of surface area, higher rate of granulation achieved in lesser time and had better outcome with wound closure by delayed primary suturing. Conclusion: NPWT is the safe and effective compare to CWT in term of duration of wound closure, faster reduction in surface area, and faster proliferation of granulation tissue.
