Vacuum sealing drainage technique combined with carbon nanomaterial dressings applied in the treatment of skin wounds

Introduction:
Limb trauma (LT) encompasses a variety of conditions and currently poses certain therapeutic challenges in clinical practice.

Aim:
To assess the effectiveness of applying the vacuum sealing drainage (VSD) technique combined with carbon nanomaterial (CNM) dressings in the nursing treatment of LT patients.

Material and methods:
Eighty-six LT patients were enrolled into a control (Ctrl) group and an experimental (Exp) group. Patients in the Ctrl group underwent conventional wound cleansing and drainage methods with regular dressings, while those in the Exp group received VSD combined with CNM dressings. Both groups received the same nursing procedures. Various indicators were observed and compared to analyse the final outcomes.

Results:
The Exp group exhibited a higher favourable wound healing (FWH) rate, overall limb functional recovery (LFR) rate, and nursing satisfaction compared to the Ctrl group (p < 0.05). Meanwhile, patients in the Exp group experienced a greatly lower incidence of complications (IOC), pain scores, and average hospital stays (HS), presenting statistically/significant differences compared to those in the Ctrl group (p < 0.05). The combination of the VSD technique with CNM dressings demonstrated advantages in nursing treatment of LT patients. This approach could enhance rates of FWH, reduce IOC, alleviate postoperative pain, facilitate LFR, and shorten HS. Furthermore, patients in the Exp group expressed higher nursing satisfaction.

Conclusions:
Results of this work yielded a novel therapeutic option for clinical practice, enhancing treatment outcomes and rehabilitation processes for LT patients.
