“…Different from the strut, which size was fixed, the pore dimension varied following the wound dressing specification applied in the NPWT device. There were three sizes of pore in literature: 0.4 mm [19], 0.5 mm [19], and 0.68 mm [20], thus generating three samples for each material, which had the same strut dimension, as well as the number of pores and struts. As a result, there were 9 samples: PCL0.68, PCL0.5, PCL0.4, PU0.68, PU0.5, PU0.4, PVA0.68, PVA0.5, and PVA0.…”

One of the wound treatments was negative pressure wound therapy (NPWT), which used wound dressings on the wound bed to ameliorate wound healing. Unfortunately, most wound dressings were two dimensional (2D), lacking the ability to cover severe wounds with a straightforward procedure. The sheets needed to be stacked following the wound curvature, which might be problematic since improper stacking could hinder the wound healing. Regarding the mentioned problems, our group develops 3D wound dressings, which are made using 3D printers. The wound dressings are made of polycaprolactone (PCL), polyurethane (PU), and polyvinyl alcohol (PVA). As the initial stage, the mechanical integrity of the soft polymers was investigated under uniaxial tensile and uniaxial compressive stress using computational methods. The polymers were defined as 3D lattices following the dimension of existing wound dressings. Based on the simulation results of displacement and von Mises stress, the three polymers are mechanically safe to be used as wound dressing materials.

“…To determine the value of the two forces, the working pressure of an NPWT device was used. On a clinical basis, a 125-mmHg negative pressure was delivered to the wound bed [19]. Considering the safety factor of 10, the load used in this study was equal to 1250 mmHg (166,653 Pa).…”

Objective: Tie-over dressing is the most frequently used technique of skin grafting. However, many deficiencies affecting the outcome have been reported. We hereby introduce a modified method, termed the ‘extra-wound fixation technique’, for skin dressing, and evaluate the complications and clinical outcomes. Method: In this retrospective cross-sectional study we analysed the medical records of patients treated between January 2012 and December 2017. All patients received full thickness skin grafts. Patients were divided equally into to groups: patients were treated using the extra-wound fixation technique, and the remaining, randomly selected patients treated using the traditional tie-over method. The extra-wound fixation technique uses the traditional tie-over dressing method followed by additional stitches made in healthy skin locating 0.5-1.0 cm laterally to the wound edge. The follow-up outcomes between the two groups were compared using the Chi-square test. Results: A total of 38 patients took part (19 patients in each group). The follow-up duration was 1–6 months. No raised edges were observed in any of the patients. Prolonged follow-up demonstrated that the grafted skin texture became soft with a thin layer of adipose tissue, and elasticity was gradually improved along with the regeneration of dermoelastic fibre. The colour was similar to the normal skin with a smooth surface. Compared with the traditional method, the extra-wound fixation technique significantly improved the survival of the grafted skin (p=0.008), reduced the risk of laceration of the skin (p=0.001), and eliminated crater rim-like appearances (p=0.020). Conclusion: The extra-wound fixation technique could be used for different skin grafts and improve clinical outcomes compared with the traditional tie-over dressing method.
