“…[2] have demonstrated the advantages of keeping a moist environment at the wound surface rather than allowing the wound to dry out. It has been shown that the healing rate is at least twice faster when the wound is covered by a dressing in order to maintain optimal hydration [4]. Moisture on wounds accelerates the epithelialization phase of wound healing by preventing scab formation over the wound bed.…”

The sensitivity of a low-cost polymeric optical fibre humidity sensor based on transmittance changes due to evanescent wave absorption is reported using test measurements in an environmental chamber and of the skin. The layer-by-layer method was used to coat 30mm of the central unclad section of a multimode polymeric optical fibre with 7 layers of a hydrophilic film consisting of bilayers of poly(allylamine hydrochloride) and SiO2 mesoporous nanoparticles. Sensor characterisation shows a decrease in light transmission as relative humidity increases as a result of refractive index changes of the coating deposited onto the optical fibre which correlates with a commercial capacitive humidity sensor. The sensitivity obtained for the sensor coated with an optimum 7 layers was approximately -3.87x10 -3 and -9.61x10 -3 in transmittance percentage per RH percentage for the range of ~10% to ~75% RH and 90% to 97% RH, respectively. In addition, a response time of 1.5s can be seen for breath monitoring with the polymeric optical fibre humidity sensor. The proof of concept measurements made on the skin indicate that this sensor has the potential to be used to monitor humidity of the skin microenvironment within a wound dressing which can be used to provide better prognosis of healing.

“…Recently, the conventional wound dressings such as natural or synthetic bandages, cotton wool and gauzes which passively provide wound protection have been replaced by modern dressings such as usual textiles and other materials as films, sponges, hydrocolloids, gels and pastes that are capable of providing an optimum environment around the wound and delivering active ingredients or directly interacting with cells in the local wound environment to facilitate wound healing [1,2]. The ideal wound dressing should (1) prevent infection, (2) remove blood and excess exudates, (3) provide or maintain moist environment, (4) allow gaseous exchange (water vapor, oxygen), (5) be thermally insulating, (6) comfortable and easily removable without causing trauma, (7) be non-toxic and non-allergenic and (8) be cost effective [3].…”

Chitosan films incorporated with thyme oil for potential applications of wound dressing were successfully prepared by solvent casting method. The water vapor permeability, oxygen transmission rate, and mechanical properties of the films were determined. Surface and crosssection morphologies and the film thicknesses were determined by Scanning Electron Microscopy (SEM). Fourier transform infrared (FT-IR) spectroscopy was conducted to determine functional group interactions between the chitosan and thyme oil. Thermal behaviors of the films were analyzed by Thermal Gravimetry (TGA) and Differential Scanning Calorimetry (DSC). In addition, the antimicrobial and the antioxidant activities of the films were investigated. The antimicrobial test was carried by agar diffusion method and the growth inhibition effects of the films including different amount of thyme oil were tested on the gram negative microorganisms of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and a gram positive microorganism of Staphylococcus aureus. The minimum thyme oil concentration in chitosan films showing the antimicrobial activity on all microorganisms used in the study was found as 1.2 % (v/v). In addition, this concentration showed the highest antioxidant activity due to mainly the carvacrol in thyme oil. Water vapor permeability and oxygen transmission rate of the films slightly increased, however, mechanical properties decreased with thyme oil incorporation. The results revealed that the thyme oil has a good potential to be incorporated into chitosan to make antibacterial and permeable films for wound healing applications.

“…Foam and calcium alginate both have excellent absorbency. [4] Raffl was the first one to describe a practical way of continuous negative suction [5] and later its benefits were proven. [6] NPWT proved to be better than moist gauze dressings in diabetic feet, [7] effective in the treatment of chronic leg ulcers [8] and also showed better graft take p < .05.…”

Wound management is vital part of surgery. We used a non-powered, disposable, portable Negative Pressure Wound Therapy dressing (NPWT) ("Nanova™", KCI™) on different types of surgical wounds treated in one Secondary Care Hospital in Ireland. It is easy to use and is self-operated by patients. It was trialled on three patients, was well tolerated, resulting in early mobility and return to daily activities, along with rapid recovery. There was no non-compliance or adverse effects to surrounding skin. The recovery time ranged from 2-3 weeks. The use of this device positively affected the clinical outcome and resulted in early discharge from hospital, quicker recovery and early return to daily activities.
