Introduction
Nowadays, negative pressure wound therapy or NPWT is one of the most increasingly used therapies for the intervention of acute and chronic wound management (Sandoz 2014). It is a non-invasive therapy that assisted in the promotion of fast healing of acute or chronic wounds. For the reason that NPWT is relatively new area to be evaluated in many surgical wards in its efficiency and within this practice the research into NPWT is still more contemporary. It is too early provide a statement whether NPWT will have an advantageous or disadvantageous influence in wound management. While the literature tackles a variety of such theories, this literature review will direct on five main themes, which will be compared …show more content…

In clinical settings, application of NPWT varies from the thickness of the wound and the type of NPWT materials. It is important to ensure that the NPWT is working properly to allow the wound to heal. ‘The method of application entailed placing a sterile, polyurethane foam dressing, into the wound defect after it had been trimmed to shape. Adhesive drape was used to cover the foam and an additional 3 to 5 cm of surrounding intact skin’ (Nather et al. 2010, p. 354). However, Ashby et al. (2012, p. 2) only provided a short overview guide in the application of NPWT, where ‘it involves the application of a suction force (negative pressure) across wound surface via a dressing’. Meanwhile, studies on NPWT conducted by Yao et al. (2012), Nain et al. (2012) and Suissa, Danino and Nikolis (2011) did not provide methods of application when in view of the efficiency of NPWT. The method of application should be included when taking into account the efficiency of

Mr BW was transferred to gastrosurgical ward for continuous assessment related to his surgical wound. A week after the surgical intervention Mr BW commenced negative pressure wound therapy, where the perineal wound was managed by an application of vacuum dressing. The purpose of NPWT was to enhance wound healing and at the same time to remove purulent fluids from the wound. A continuous negative pressure was set to -125mmHg. At the same time, the negative pressure wound dressing was changed three times a week for the assessment of the wound.

The nursing departments in our hospital formed a joint pressure ulcer prevention task force and the task force created voluntarily. Two nurses come from each of medical and surgical units to create the task force. The task force thus comes together every Wednesday to make rounds on nursing units and check for a pressure ulcer on patients whose Braden score is less than 18. The task force is very successful in catching missed and potential pressure ulcers. The task force then reports its finding and recommendation for wound care nurse for further evaluation and treatments.

Effective clinical leaders have been linked to facilitating and maintaining healthier workplaces, by driving cultural change among all health professionals in the workplace. To achieve these positive outcomes, clinical leaders need to be seen as credible – that is, be recognized by colleagues as having clinical competence and have the skills and capacity to effectively support and communicate with members of multidisciplinary clinical teams. Taking an individual perspective, effective clinical leaders require personal qualities that reflect positive attitudes toward their own profession, have the courage and capacity to challenge the status, effectively address quality issues, and engage in reflective practice (Daly J, Jackson D, Mannix J,

Stephen Sprigle and Sharon Soneblum, also, report in their article Assessing evidence supporting redistribution of pressure for pressure ulcer prevention: A review that impaired skin integrity results in the development of pressure ulcers, also commonly referred to as bed sores. Pressure ulcers are caused by pressure characterized by magnitude and duration exerted onto the tissues. Sprigle goes on to indicate that, as evidenced by research of Callum et al, outcomes of constant low pressure support produce better results than standard mattresses found in the majority of hospitals. These devices work by decreasing the magnitude of sites with the greatest potential for ulcer formation, bony prominences (2011).

This initial investigation can also include interviews of the staff involved as well as the patient and the any family members that were present. This information includes the data that was collected and is useful in deciding how the performance improvement department selects candidates to serve as members on the team. It is important to involve facility leaders to prioritize the project and proceed with the RCA. My facilities justification for examining why patients continue to develop pressure ulcers was due to the fact that the performance improvement department acted on reports received from the orthopedic department. After the initial investigation period the team they assembled included the nurse manager on our floor, several of the senior clinical nurses, as well

I was exposed to several techniques when aiding a wound to heal that can not heal itself. There were several techniques and supplies used for each individual wound. Coming in with this knowledge I am now aware of what to focus one when we cover wound care within the program. For example why dress a wound with medihoney versus hydrofera blue. It is a realm within physical therapy that I am highly interested in and will likely gain certification in the near future.
