Hydrocolloids in pressure ulcer prevention
Hydrocolloids in pressure ulcer prevention
The meta-analysis of pediatric patients showed that in the hydrocolloid dressing group, 4 patients 1. Although various topical agents and protective dressings have been historically and anecdotally used as preventative strategies to maintain healthy skin, conclusions of the Cochrane review do not support this practice. Sensitivity analysis was performed by changing the effect model. Methods Search strategy. Three studies also confirmed the hydrocolloid dressing was associated with a statistically significant reduction in wound volume compared with the gauze dressing. Stronger randomized control trials and case series are needed in order to support the guidelines in this area. Shearing forces significantly decrease the threshold of tissue damage.
A final score of is defined as low quality and as high quality. The Jadad Scale of all included studies scored 2, which indicated low quality.
Zha are graduate students; and Dr. The overall prevalence rates and facility-acquired pressure ulcer rates were The main types of dressings that are examined for this purpose in the literature are foam, hydrocolloid, and films.
Subgroup analyses were considered when the participants were at different age levels or used different control group interventions. Individuals who acquire pressure ulcers often require long-term interventions, representing a large economic burden to the health care system.
In the 13 studies,28,31, in which regular skin care was the control, 40 patients 4. In addition, no English language studies were found; the included articles were all Chinese studies, which may contribute to bias and make it challenging for non-Chinese researchers to confirm current findings.

Results primary studies were identified, 69 were evaluated and nine were selected, referring to the use of the hydrocolloid dressing in healing; of these, four studies allowed meta-analysis. These 2 studies reported the use of different methods to prevent facial PUs, but the outcome was similar to the current research. They affect thousands of people around the world at the different levels of health care, with the adult and older adult population standing out. The hydrocolloids are interactive dressings, made up of an external layer of polyurethane and an internal layer of gelatine, pectin and carboxymethyl cellulose, which produce an ideal humid environment in the wound bed, control the exudate, facilitate the autolytic debridement, contribute to pain management and provide a barrier to external microorganisms 6. Funnel plot showed asymmetry that indicated possible publication bias in this meta-analysis Figure 3. Data extraction. Effective strategies to treat pressure ulcers are use of support surfaces, nutritional supplementation, and local wound care by wound dressings, biological agents, and adjunctive therapies. This is especially true in areas where the skin covers thin subcutaneous tissue chin, cheekbones, forehead, and nasal bridge and excessive pressure predisposes to the development of PU. Other inclusion criteria were: the study was an RCT, the objective was assessing the effectiveness of a hydrocolloid dressing regardless of brand in preventing facial PU, the intervention comparison involved a hydrocolloid dressing versus a control, and the outcome was the incidence of facial PUs. Accordingly, the authors suggest that in the treatment of pressure ulcers, traditional gauze dressings should be abandoned. Data extraction. Quality assessment. Characteristics of the studies from the 7 articles included in meta-analyses are shown in Table 1.
The degree of agreement between the reviewers was established using the kappa coefficient 15and the level reached was 0. They promote angiogenesis, increase the number of fibroblasts of the dermis, encourage the production of granulation tissue and increase the quantity of synthesized collagen, all of which are essential in the healing process Because the conclusions reached were mostly based on low-quality RCTs, the findings need to be further verified with more high quality RCTs.
Extraction of the data and statistical analysis For extraction of the data, a predefined form was used, which covered the following information: identification of the studies title, Journal, year of publication, volume, number, authors ; objetives; method method of randomization, blinding, number of randomized patients, description of follow-up losses, inclusion and exclusion criteria, age, standard deviation and sex, stage of the PU and clinical characteristics, intervention in the experimental group and control group and outcomes.
