Annotated bibilography on evidence based research-pressure ulcers Essay

Annotated bibilography on evidence based research-pressure ulcers - Essay Example The available literature identifies its risk factors as: physiological alterations, diabetes, low tissue oxygen tension, nutritional deficiency, contractures, and paralysis. This annotated bibliography examines the effectiveness of different treatment and prevention strategies used in hospital settings. The available statistics suggest that the condition mainly affects male adults, and 3-10% of the hospitalized population. The risk of pressure ulcer is also high among neurologically impaired patients, and persons disabled by the spinal cord injuries. According to Mendez (2004) prevention is a key component of managing pressure ulcers, and the presentation of this condition occurs in 4 stages starting with erythema and ending with the infection of the underlying bone or muscle. Stage 1 is characterized by the reddening of the skin while in stage 2, the skin blisters form open sores. In the third stage, a crater is formed while in the final stage, the damages extend to the tendons, joi nts, muscles and bones. Some of the treatment method used include: de-pressurizing of the affected areas, surgical reconstruction, administration of and antibiotics. While treatment of the affected patients should be administered as soon as possible, prevention should be the first priority for the population as risk of this condition. In this regard, patients on bed rest should be checked frequently for pressure sores. Symptoms to watch out for include: red skin, open sores, blisters, foul smells from the ulcers, and swollen skin. For early detection, the caregiver should consider giving the patient a head to toe examination, and should pay close attention to the following areas: buttocks, elbows, hips, heels, ankles, shoulders, and back. For prevention of this condition, persons at risk should change positions once in every 2hours and use appropriate tool to cushion the affected areas. Most importantly, they should eat well balanced meals, drink lots of water, exercise regularly, u se creams to protect the skin and keep the skin dry and clean at all times. Reddy, M., Sedeep, S., & Rochon, P. (2006). Preventing pressure ulcers: A systematic review. Journal of the American Medical Association, 296(8), 974-984 This article which is written by competent authors seeks to examine the adverse health outcomes and treatment costs associated with pressusre ulcers. The objective of the article is to review the evidence examining interventions to prevent pressure ulcers. The systematic review utilizes sources from the MEDLINE, EMBASE and CINAHL. All the databases are well known for publishing credible article dealing with different medical condition. The search strategy identified 763 citations, of which 59 randomized control trial were selected. As suggested by Moore and Cowman (2007), systematic review should have elaborate schemes to prevent bias, and maximize precision of the data obtained. At the same time, it should have a detailed exclusion and inclusion criteria, use clear research questions and adequately address the challenge of assessing the methodology quality of the selected studies. If possible, the systematic review should depend on current and credible secondary sources. In this case, of the citations identified, 650 were excluded since they were not randomized clinical trials, while 53 did not have adequate information about the outcome measures. The

Banded Iron Formation of Bonai-Keonjhar Essay Example | Topics and Well Written Essays - 250 words

Banded Iron Formation of Bonai-Keonjhar - Essay Example BK is the youngest iron ore in the horseshoe belt. The focus is on Banspani-Jilling–Jajang bit of the iron ore. BIF of Banspani-Jilling–Jajang section of BK belt covers a section of the Precambrian super crustal north Odisha iron ore super group. Geology: the BIF hosts tabular strata-bound bodies mainly formed of high-grade hematite ores. Banspan-Jilling–Jajang covers about 40 sq. km. above the BIF lie the high-grade hematite ores which cover three stratigraphic positions. The southern range has massive and hard laminated cores. These ore bodies form the bulk of the resource. They are tubular in shape, irregular in size and have a thickness ranging from 2 and 50m. Langalata forms the bulk of the ore deposit, taking about 73% of it. Banspani-Jilling–Jajang deposits have a total reserve of about 61.7 million tons. Petrography: the rock types in the study area include banded hematite Jasper (BHJ), banded manganese formation (BMnF), banded hematite shale (BHS), banded shale, banded hematite quartzite (BHZ) and iron ore bodies. BHJ and BHZ are dominant rock types. They have alternating bands of silica and iron mineral. Some of the iron minerals in the BIF include goethite, martite, partitioned magnetite, hematite, and specularity. Hematite is the dominant iron mineral in the area. The varieties of silica forming alternate bands with the mentioned iron minerals include jasper, quartz, and chert. The iron minerals are formed by three distinct processes; thematization, marketization, and graphitization.
