Prevention of pressure ulcers: nurses’ sole responsibility

Prevention of instancy ulcers nurses sole responsibilityPressure ulcer is a major(ip) health problem. According to previous 10 years nationwide studies, 10% to 15% of the general cosmos suffers from chronic thrust ulcers. In addition, Reddy, Gill and Rochon (cited in Walton-Geer, cc9) approximated 60,000 patient roles every year will die from infirmary acquired blackmail ulcers and the treatment of these wounds termss approximately $11 billion per year. These findings argon real in both(prenominal) areas such as patients in intensive care units, critical care units and nursing home residents. These situations cost patient in terms of suffering, impaired fiber of life, reduced independence and even increased morbidity and mortality. The patients delay in infirmary discharge and decrease the efficiency and efficacy of health services. The health industry is in addition concerned about lack of sources, work force hours to manage the problem. Various industries and government agencies are disconcerted to either treat these ulcers in early intervention or encourage prevention (Lippincott Williams Wilkins, 2007). However, a good character care is grave in preventing these sores and nurses come at front to provide this care. In identifying the nurses posture towards care and perception of restrictions in that case may solve this situation.Search strategyThe belles-lettres search was conducted by development the databases- Cinahl, Pro Quest, Pub med and Waiariki library catalogues. These databases identified the published studies, nursing journals and congregation proceedings. The search engine mapd the terms for search were cart ulcers and nursing, nurse and bedsores, nurse and hospital, twinge ulcer and patient, and nursing management and decubitus ulcers to search out the articles. The articles only written in English were retrieved for go off. This publications re office is ground on the prevention strategies. Prevention and management of p ressure ulcer is of major concern in health care system. close of the studies revealed the appropriate companionship of nurses for prevention. The gaps could be in the lack of performance in their practice. The hospital routines for early sound judgement and culture may be obligated for nurses to practice efficiently. Despite of change magnitude expenditure neither incidence nor prevalence is reducing. The attitude and supervision towards care of patient are significant review in whole populations gener ally. The search was wide to find the reliable material and needed to squeeze out some for relevance. The search boundaries were elaborated for nursing practice and attitude. The access to literature was some periods limited to purloin only.Eighteen published articles were reviewed for affirmable inclusions in the final review. Among those ten articles were taken from previous conducted researches, three were the literature reviews and two relevant articles were based on life story of patients. unrivalled textbook and two non-research articles were unploughed for buttocksground information. The inaugural line of defense in preventing the pressure ulcer development is the nurse practitioners carriage towards patient, nursing care by employ various devices, patients stead for devolving encounter factors and hospital polices for further improvements. every ages were viewed as inclusion criteria with high-risk abilities. Four articles were more than ten years old and excluded to gather flow knowledge for practice. One dissect was excluded because of emphasize was put on various positions of the patient that are un stiff for critical care units to take efforts in rising out of bed and were non valid. Two researches based studies were include to assess nurses knowledge in prevention and treatment strategies that were mainly researched for assessing the nurses knowledge about pressure ulcers and impact on practical decision-making skills and utili zations of various devices. The research literatures on pressure ulcer development make full the pedagogics and reliability legal opinion of nurses. One group of researchers created the longitudinal examination of hospital registered staffing to improve the quality of care and revealed the limited support for quality with number of registered nurses. These variations in favor of care presents a trail comparison of results, at best. some other(a) research use up revealed the influence of handling technique, and patients weight and disability that causes in force(p) back injuries to nurses. One research supported computers for prevention and treatment of pressure ulcers at LCD hospital was included because the system reminds documentation to nurses. One life story article included tells about the heedlessness in care that guide ons towards the death of a woman, because of os deep bedsores that remained untreated in last hexad months of her life.The selection criteria in th ree researches consent been taken for use of burden devices that underline the risk of pressure ulcers early assessment at term of admission. The potential inclusion admits a risk assessment tool, Braden outperform in predicting pressure sore risk in hospitalized patients. However, two included studies exposed issues regarding the lack of clinical trials for effectiveness and the quality improvement implementations in nursing homes that associated with organizational culture. As the review included all ages, hospitalized and outside patients, one study assures about the sitting behavior of people lead towards building the risk of pressure ulcers.Nurses knowledge and attitudeIn 2004, Moore agree the development of pressure ulcer is linked to nurses attitude, study and competence. Education increases awareness of the problem and gives a pathway for developing and maintaining competency. Thus, the successful prevention is dependent on staff knowledge, skill and attitude. This arg ument was underlined the content and quality of education, a major concern in decision-making. Hulland (cited in Moore, 2004) was able to identify nurses action, feelings and opinion on pressure ulcer prevention and treatment. Anthony (cited in Moore, 2004) also agreed, however, nurses have good knowledge for prevention, still usage is inappropriate in practice. Maylor and Torrance (cited in Moore, 2004) supported the assess of the attitude of nurses for preventive practices of pressure ulcers in clinical practice. Ousey (2010) accented the need of evidence-based education for whole staff twisting in care of pressure ulcers. Another study by Wiechula in 1997 described the focus of quality improvement ought to on the appropriate education program that contains the instructions and guidelines of current and evidence based practice. The education program should include the etiology and risk factors along with risk assessment tools and application in demonstrating the stance for pre vention of pressure ulcers. In this study, the stress was also put on the accurate documentation and monitoring. Another cross-sectional study by a group of researchers explored the comparison surrounded by the knowledge among past time and present time nurses. The sample was large (n=522 nurses in 2003 compared with n=351 nurses in 1991), with written questionnaire method. The authors identified the knowledge of nurses in 2003 is better and nurses know the usefulness of preventive measures. However, the raised issue was again the knowledge did not come in practice in the organizations that monitored pressure ulcers (Hulsenboom, Bours Halfens, 2007). Comparing the views of all authors, one group of researchers conducted a one-time survey. Fifteen nurses were subjected to check the use of system increase their knowledge and skills. The study resulted in no effective knowledge about pressure ulcers and decision-making skills in practice (Zielstorff et al, 1997). Among various resea rches, one study by smith and Waugh in 2009 uncovered the nurses knowledge of pressure ulcer prevention and treatment along with the perception of barrier in providing effective care. After using the Pieper Pressure Ulcer Knowledge Test among 96 nurses, the study revealed the nurses knowledge was higher significantly but the barrier such as the weight of patient, patients refusal, unavailability of equipments, not having enough time and staff was significantly considerable. Nevertheless, Mark, Harless, McCue and Xu in 2004 shew limited support for enduring the belief that improvement in registered nurse staffing improves the quality of care. In addition, Skotte and Fallentin in 2008 supports the barrier by assessing the low back load on health care workers while using preventive techniques such as shift and use of friction reducing devices that is higher than patients weight and disability. Pulkkinen (2009) explores this argument in an article about a health care workers second-de gree criminal mistreatment. The evidence shows that the treatment for bedsores was not provided to Harrison and ultimately because of gangrene infection of bone deep ulcers, he died.Use of appliances in practiceIn 1997, Wiechula described the assessment of risk is important to consider causative and contributing factors that can eliminate the negative effects. This skin care assessment of patient should be at the time of admission, later on change in condition and for long-term patients at unvarying intervals. Specifically, to relieve pressure, attempt should be put on positioning and turning frequently. The major concern was preventing allude on between prone areas and support outdoors by using devices such as pillows and foams and use of alternating pressure mattress for high-risk patients. Ousey (2010) explored the early detection and effective documentation of pressure ulcers is a make component of quality care if the nurses can identify risk development behavior appropriat ely. The study assures manual of arms repositioning and pressure relieving support surfaces are important in preventive measures. The early detection includes the assessment within six hours of admission in hospital and in community settings it should be at first visit of practice nurse. However, Wiechula in 1997 outlined, turning of patient every 2 hours is a reliable and seedy method of prevention. Schoonhoven (cited in Ousey, 2010) disputed the effectiveness of preventive measures in some patients. Based on this notion, Ousey agreed the pressure ulcer tool will be answerful for high-risk individuals if practice with professional jugdement. Stotts and Gunningberg in 2007 supported one evidence-based article for use of Braden scale, a good assessment tool. Considering the reliability and validity, Braden scale is emotive to practice with the difference in patients culture. In the matter of devices in care of pressure ulcers, the Australian aesculapian sheepskin is a new pressure -relieving device is effective in relieving pressure with moisture absorbing capacities (Mistiaen et al, 2008). Gardner, Frantz, Bergquist and shinny (2005) explored another perspective study for measuring the wound healing is pressure ulcer scale for healing. When the workers harbor this evidence-based tool at weekly intervals, it provides accuracy in differentiating healing of pressure ulcer from non-healing in track changes in pressure ulcer status. This study outlined the use of PUSH score can attain changes during extended follow-ups during the time when pressure ulcers take more than 3 months to heal. As explained by Wiechula in 1997, massage on bony prominences ought to avoid and the ring shaped devices are ineffectiveness in practice. Ousey (2010) agreed the view of not rubbing the skin vigorously to prevent the damage of superficial and deep tissues. Interestingly, one cross-sectional study unveiled the use of these preventive devices and documentation is suboptimal ev en for high-risk patients. In practice, the documentation and preventive devices are important for all patients who are at risk and having pressure ulcers to note the status of patients. A research nurse to ascertain the use of pressure ulcer devices examined the patients. After examination, 68% patients were documented for pressure ulcers. Among those 15% of patients had preventive devices and 51% receive those were at high-risk. In multiple analyses, the type and stage of pressure ulcer were not associated with high-risk patient but the use of preventive devices (Rich, Shardell, Margolis Baumgarten, 2010). Similarly, Moore (2004) identified the use of pressure relieving devices are not as much helpful in reducing the prevalence of pressure ulcers without nurses domineering attitude.Hospital policyThe cost of treatment of pressure ulcers can be enormous and significantly die hard out the health system resources. According to Posnett Franks (cited in Ousey, 2010) the estimated c ost for the treatment of pressure ulcer is between 1.8 billion pounds to 2.6 billion pounds annually. In 2009, Walton-Geer gave views on for the improvement in patient care the interventions should be initiated on evidence-based practice.Patients statusAHCPR (cited in Wiechula, 1997) recommended the important link of malnutrition with the development of pressure ulcers. Wiechula (1997) indicated, on admission nutritional assessment should also be monitored such as weight changes, loss of appetite and decrease dietary intake. Patients with little hygiene and skin moisture degrade the integrity of skin that further helps in developing sores. One literature review supported the components of Braden scale such as nutrition, sensory perception, evidence of moisture, activity level and mobility status are the most important predictive of developing risk of pressure ulcers. It is apparent in the study that the risk increases with the susceptibility of tissue tolerance and slimy peripher al circulation that relates with poor nutritional status (Schultz, 2005). Ousey in 2010 outlined some intrinsic and extrinsic factors responsible for pressure ulcer development. Intrinsic factors included patients age, mobility, incontinence, medication, anemia, thin skin, nutritional status and disease condition. The considered extrinsic factors were friction, moisture, poor handling and changing position. The stress was also put on initial assessment of all patients to improve nutritional intakes. Williams et al (cited in Ousey, 2010) considered poor nutrition and decreased tissue perfusion, the main cause of pressure ulcer development. Bain and Ferguson-Pell in 2002 considered the knowledge of sitting behavior of patients outside the hospital especially for wheel chair users who sit continuously for long time. The study tested the use of remote monitoring pressure distributing logger that keeps the record of sitting behavior afterward testing its feasibility.Phytochemical Method Silver Nanoparticles synthetic thinkingPhytochemical Method Silver Nanoparticles SynthesisPhytochemical Method Silver Nanoparticles Synthesis and CharacterizationThe study of green synthesis of nanomaterials offers a valuable contribution to biomedicine at nanobiotechnology. This study focuses on the green synthesis of nano facile gray from O. holy jerk extract and loading the nano liquid onto cotton fabrics and assessing their physical and biological properties.In this study, O. sanctum flicker extract was utilize as reducing agent for the synthesis of bullion nanoparticles. When the eloquent treat solution was mixed with leaf extract, the color changes occur immediately in liquid nitrate solution. Initially, the leaf extract was green, which turned yellowish brown on adding the flatware nitrate solution. The color changes indirectly indicate the formation of fluid nanoparticles.The color change was noted by virtual observation of O. sanctum leaf extract incubated with an aqueous solution of AgNO3. It started to change color from watery to yellowish brown at 4 h and dark pink at 24 h after incubation ( write in code 1). It is out-of-pocket to the reduction of silver ions this exhibits the formation of silver nanoparticles (Table 1). The color of the extract changed to intense brown along with locomote after 24 h of incubation, and there was no significant change afterward.S.No.Time interval illusion change10 minDark green210 min pallid green330 minReddish green41hrRed52 hrsRed64 hrsReddish brown78 hrsReddish brown816 hrsBrown Threads924 hrsBrown ThreadsTable 5. 1. Effect of leaf extract of O.sanctum on colour changes in silver nitrate solution at different time intervalBiosynthesis of nanoparticles by time-dependent absorption spectrumThe continuous formation of silver nanoparticles was investigated using UV-Vis spectroscopic analysis, which has proven to be a useful spectroscopic method. The presence of silver nanoparticles was confirmed at a range of 200600 nm. In UV-Vis spectra, silver nanoparticles can be shown by a SPR flowering at around four hundred nm, but a small shift (blueshift or redshift) in the wavelength of the peak could be related to obtaining silver nanoparticles in different shapes, sizes, or solvent dependences. After 24 h of incubation, a typical peak of max at 421 nm was obtained due to the SPR of silver nanoparticles (Figure5. 2).After the response time on adding of leaf extract reached 4 h, obtained silver nanoparticles showed a UV-Vis absorption peak, a characteristic SPR band for silver nanoparticles, touch at 400 nm (Figure 5.2).Figure 2, the intensity of the SPR peak increased with the increase in the reaction time, which indicated the continued reduction of the silver nitrate ions, whereas the increase of the absorbance set with the reaction time indicated the increase in concentration of silver nanoparticles.When the reaction time reached 12 h, the absorbance was increased and max value was slightly blueshifted to 435 nm. At reaction time of 24 h, the absorbance value was also increased and blueshifted to 435 and 421 nm, respectively. At the end of the reaction (24 h), the absorbance value was considerably increased and there was no significant change in max value (421 nm), compared with that at 12-h reaction time.FTIR spectroscopy analysis of biosynthesized silver nanoparticlesFTIR measurements of the biosynthesized silver nanoparticle samples were carried out to identify the possible interactions between silver and bioactive molecules, which may be responsible for synthesis and stabilization (capping material) of silver nanoparticles. These were also to identify the possible biomolecules responsible for capping and efficient stabilization of the metal nanoparticles synthesized by leaf extract.Figure 5.3 shows the FTIR spectra of aqueous silver nanoparticles prepared from O. sanctum leaf extract. The presence of the signature peaks of amino acids supports the pres ence of proteins in cell-free filtrate as find in spectral analysis. The silver nanoparticle sample shows peaks at 3313.48, 3193, 2976.90, 2883, 1670, 1452, 1338, 1196.78, and 1112.75 cm1 (Figure 5.3). The peaks corresponding to protein and silver nanoparticles were found commonly present in the nanoparticles synthesized by leaf extract.roentgenogram diffraction analysisThe crystalline nature of silver nanoparticles was studied with the aid of XRD as shown in Figure 5.4. The dry powders of the biosynthesized silver nanoparticles were apply for XRD analysis. The diffracted intensities were recorded from 20 to 80 at 2 angles.Many strong Bragg diffracted peaks observed at 27.82, 32.25, 46.22, and 76.63 corresponding to 126, 199, 131, and 24 tip of the face-centered cubic pattern of silver were obtained. The medium grain size of the silver nanoparticles formed in the bio-reduction branch was placed using Scherrer formula and it suggested that the synthesized silver nanoparticles w ere crystalline.The size of the silver nanoparticles was found to be 26 nm, and it was determined using the width of the (126) Braggs reflection. In addition, yet some unassigned peaks were also observed suggesting the watch glass of biophase occurs on the surface of silver nanoparticles.Fluorescence spectral analysisFluorescence spectroscopy is a type of electromagnetic spectroscopy which analyzes fluorescence from a sample. Figure 5.5 shows fluorescence emission spectrum from silver nanoparticles, dispersed in double distilled water. Fluorescence spectral analysis of silver nanoparticles used in the experiment was carried out to confirm the fluorescence emitted from the nanoparticles. A strong maximum at 431 nm wavelength and a quantum yield was 666.450 mV appeared in the fluorescence emission spectrum of O. sanctum leaf extract mediated silver nanoparticles.Potentiometry analysis of biosynthesized silver nanoparticlesThe biosynthesized silver nanostructure was shown and confirme d by the characteristic peaks observed in zeta potential, which will help to measure the diameter of nanoparticles with corresponding average zeta potential values, and also used for suggesting higher stability of silver nanoparticles. The reduction of silver ions to form nanoparticles was also monitored using a potentiometer.The large negative potential value could be due to the capping of polyphenolic constituents present in the extract. Figure 5.6 shows the results of time-dependent zeta potential analysis from 0 to 24 h of incubation period. A pointed reduction in the potential could be observed on 4 h of interaction, further indicating the formation of nanoparticles at this stage. The potential decrease from an initial value of 0.436 V for silver ions to 0.153 V at the end of 11 h (Figure5.6) was observed, after which the decrease in potential was gradual, decreasing up to 0.048 V at the end of 24 h.Zeta potential analysis of synthesized silver nanoparticlesThe zeta potential a nalysis was used to measure the electrophoretic mobility of the silver nanoparticles. The complex zeta potential is a parameter that is used to learn the surface charges and stability of nanoparticles. The zeta potential charges significantly affect the particle distribution and agglomeration of nanoparticles. The high zeta potential value indicates a high electric charge on the surface of the nanoparticles. It describes strong repellent forces among the particles, which prevent aggregation and lead to stabilization of the nanoparticles in the medium. The zeta potential of the nanoparticles formulated was only measured in systems that did not sediment after overnight equilibration.The alteration in zeta potential with a moment in time is shown in Figure 5.7. It can be observed that there was charge stabilization from 11 to 16 h, with the charge stabilised at around 57 mV. The zeta potential was 62 mV for the 14 h interacted samples, which further decreased to 35 mV for the 24 h inte racted samples.SEM analysis of silver nanoparticlesThe morphology of silver nanoparticle was observed using a SEM instrument. The shape and size of silver nanoparticles were analyzed after 24 h of incubation using SEM as shown in Figure 5.8. In general, the nanoparticles were spherical with varying size ranged from 7 to 28 nm. Most of the nanoparticles were combined, with only a few of them scattered, as observed under SEM.The biosynthesized silver nanoparticles were mostly spherical. These were used to measure up the morphology, size, and distribution in aqueous suspension and were prepared by dropping the suspension onto a unfermented glass plate and allowing water to completely evaporate. It was evident that the ends of silver nanoparticles are brighter than the middle, suggesting the particles are encapsulated by biomolecules such as proteins in the Basil leaf extract (Figure 5.8).EDS analysis of silver nanoparticlesThe EDS spectrum (Figure 5.9) clearly identified the element al composition of the synthesized nanoparticles, which suggests the presence of silver as the ingredient element. The vertical axis shows the counts of the X-ray and the horizontal axis shows energy in keV. The strong signals of silver correspond to the peaks in the graph convinced(p) presence of silver. Biosynthesized silver nanoparticles typically show an optical absorption peak at 3.2 keV due to SPR. However, other elemental signals along with silver nanoparticles were also recorded, which were not observed for the biosynthesis of many other nanoparticles.TEM was used to visualize the size and shape of silver nanoparticles. Figure 5.10 shows the typical TEM micrograph of the synthesized silver nanoparticles. It is observed that most of the silver nanoparticles were spherical. A few agglomerated silver nanoparticles were also observed in some places, thereby indicating possible sedimentation at a later time. It is evident that there is variation in particle sizes, and the average size was estimated to be 26 nm and the particle size ranged from 8 to 45 nm. The natural products, videlicet glycosides, flavanones, and reducing sugars, are the main constituents of the O. sanctum leaf extract
