Literature Review of Risks Prevention of Pressure Sores

Literature Review of Risks Prevention of Pressure Sores A review of literature provides the concept to continue for the contemplated research, an understanding of the status of the research in the problem area includes research approach, method, instrumentation, and analysis. The literature review is organized under the following headings: Review related to the prevalence of pressure sore Review related to the etiology and risk factors of pressure sore Review related to the prevention of pressure sore Review related to the caregivers of pressure sore Review Related to prevalence of pressure sore Hendrichova.I et.al (2010) have done Retrospective analysis of 1414 clinical records of patients admitted over 6 months and found prevalence of pressure ulcers of 22.9 % and incidence of 6.7 % Forni C et. al (2009), conducted study regarding cohort study of the incidence of heel pressure sores in patients with leg casts at the Rizzoli orthopedic hospital and also the associated risk factors at Italy. He found that out of 216 patients 17.6% (38) developed a pressure sore: 16/124 in orthopedic wards; and 22/92 in cancer care units. The related risk factors of pressure sore were noted are administration of anti neoplastic drugs (p = 0.033) OR = 2.61; skin redness before cast application (p = 0.001; OR = 4.44), reported symptoms after the application (p = 0.000; OR = 7.86). Most of the pressure sores were mainly in the stage 1 and stage II was 6/216 (2.4%). Voweden KR and Vowden.P (2009) conducted study regarding the prevalence of pressure ulcer, management, equipment provision and outcome for patients with pressure ulceration and identified in a wound care survey within one English health care district on 1000 population in the tertiary referrals and prevalence of 53.7 % were classed as grade 2 pressure ulcers, 48 % were grade I and only 35 % of grade 4. Pressure ulcers were identified through the critical incident form are only about 11 % of pressure ulcers at hospital setup and gives the current Epidemiology of pressure ulcers. Harrow J.J et.al (2008) conducted study regarding pressure ulcers and occipital alopecia in operation Iraqi Freedom poly trauma casualties: retrospective review from 2004- 2006 to detect the prevalence and severity of pressure-related injuries and stated that 38% of admissions to this hospital had pressure-related injuries on the day of admission. In which Casualties from Iraq had a higher rate of pressure ulcers (53%) than other area (22%). Occipital lesions accounts 50% of non-stage I pressure ulcers and more severe than of the sacrum or in the extremities. Review related to risk factors associated with the pressure ulcer: Lahmann N.A.et. al (2010) done, study regarding impact of prevention structures and processes on pressure ulcer prevalence in nursing homes and acute care hospitals, by the method of prevalence survey among 7377 residents in 60 nursing homes and also 28,102 clients with 82 acute-care hospitals at Germany by annual point prevalence surveys. Results noted are nosocomial prevalence rates in hospitals decreased from 26.3% during the first year to 11.3% in the last year (mainly in nursing homes from 13.7% to 6.4%). The usage of pressure ulcer-related structures conspicuous more during each repetition to more than 90%. Fisher A.R et. al (2004) conducted cross sectional prevalence studies among 535 patients regarding f pressure ulcers in adults in acute care settings at university teaching hospital, Canada and found the prevalence of pressure ulcers was 27% (at 95% confidence interval, 23-31%). Total Braden score below 17 and increasing age were significantly associated with the presence of pressure ulcers and also found majority of the risk factors are increasing age, less activity level, friction and shear while seated or lying down were associated with hospital-acquired pressure ulcers, only increasing age, friction and shear were associated with the presence of pressure ulcers in the whole sample. Silva M.S et.al (1998) conducted exploratory- descriptive study to identify, in the specialized literature, which predisposing conditions and risks factors would be related to the development of pressure ulcer, and to verify how often these predisposing conditions and risk factors would be present in bedridden patients, hospitalized in an institution and concluded that there is the need to construct an instrument to measure this risk must suit our reality and that incorporates risk factors identified with a significant frequency in this study and are not contemplated in most of the available scales in the literature. Review related to the prevention of pressure sore Baldi et .al (2010) conducted study regarding Studying factors related to pressure ulcers prevention: a marginal scale model for modelling heterogeneity among hospitals. in patients referred to several Italian hospitals, with the method of prevalence survey co ordinate through the European Pressure Ulcer Advisory Panel among 12 000 hospitalized patients in Italy, and results shows that the prevention of pressure sore includes usage of Braden Scale, age and assistance- connected aspects, and usage of preventive equipment combined with a repositioning techniques. Wann-Hansson C et .al (2008) conducted study in sweedish University regarding Risk factors and prevention among clients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present during admission with 535 clients and notified the prevalence rate of pressure ulcers were 27% (95% confidence interval, 23-31%). Shahin E.S (2008) conducted study regarding prevalence of pressure ulcer among intensive care cltients: a cross sectional study at German with the sample of 1760 clients in order to assess the pressure ulcer prevalence among intensive care clients, and also found clients characteristics and preventive measures related to prevalence of pressure ulcer clients and to assess the most common sites of pressure ulcers. A result shows a mean prevalence rate was +/-30% from 2002 to 2005. The pressure sore prevalence was decreased to 16.2% in 2006 and half of the pressure ulcers were in grade 1. He has stated the significant association between the age and pressure ulcer (P

Bio Lab Report Crime Scene

On Saturday morning of the 24th of October, there was report by an employee of a homicide incident on 4011 N. Central Eave, Phoenix, AZ. University Center building on the 3rd floor of Arizona State University. The victim was describe as a 24 year old Caucasian female, by the name of Kelly; who works as a programs coordinator for Arizona State University. The victim was working late hours as usual on a Friday night, she was on her office cubical.The body was found laying on the floor in front of her desk chair, the body was facing up with three bullet wounds on her body; the action of the shots were one in right shoulder, right hip, and middle of the stomach. Observations found in the crime scene were the chair was knocked over, the victim was facing up instead of facing down. There were bullet holes in the wallboard as well as the cabinetry and biological stains of the victim. Information gathered about the victim she appeared to be talking to her mother while the incident happen, an d it was not unusual seen her work late at night.Also, there was some information about five suspects that might have been involve in the homicide. Licensee Scale S. Microbiology Professor, at the time of the murder he stated he was looking for money from students so he could buy another pint of beer, and was wearing blue t-shirt and jeans. Daffy Patrick D. Microbiology Lecturer, at the time of the murder he stated he was drinking at Hooters and was hearing a blue button down shirt and black pants.Olson John P. Biology Professor, at the time of the murder he stated he was at an all night Chinese buffet, and was wearing blue flannel shirt and Jeans. Hutchins Jason O. Chemistry Lecturer, at the time of the murder he was teaching Chemistry 101 lab, and was wearing a blue polo shirt and Jeans. Waffle Debra A. Lab Technician, at the time of the crime scene she stated she was preparing for Microbiology 206 lab, and she was wearing blue lab coat and khaki pants.The homicide case is under i nvestigation, once there has been examine the pieces of hair, fabric, and blood samples from the suspects, it will be determine who was the murder of the victim. Methods and Materials The investigation began by first collecting evidence from the crime scene and suspects. This includes fingerprints, hair and fiber samples, along with blood samples. Along with these, a bullet was found at the crime scene, which was added to the list of evidence. Fingerprint Testing To collect the fingerprints from both the suspects and the crime scene, the print lifting technique was used.This method included using a fingerprint wand and powder to dust the fingerprints on the object, and then putting adhesive tape over the latent prints to â€Å"lift† the fingerprints' image. The adhesive and fingerprint were then transferred to a backing card to be examined. To analyze the prints, a magnifying glass was used to determine if the prints pattern was an arch, loop or whorl. The fingerprints examin ed are a type of biological evidence. Fingerprints Suspect Arch Loop Whorl Daffy x HutchinsLicensee Olsen Waffle We then compared these fingerprint patterns with the fingerprint collected at the crime scene, which was a loop. Metallurgy Next, the bullet found at the crime scene was tested using metallurgy. The bullet was a type of physical evidence. To determine what type of metal the bullet was made of, the densities of the three standard metals in the tool kit had to be determined. To measure the metal's mass, an electronic scale was used while a water displacement was used to measure the volume. From these measurements, the density was calculated (D=MN).The mass, volume and density of the metals in the kit were lactated as follows: ; Aluminum o Mass = 8. 27 g Volume = 4 ml = 2. 07 vim Density = MN Copper Mass = 57. 1 g Volume = 7 ml Density = MN = 8. 16 g/ml o Mass = 37. 95 g o Volume = 4 ml o Density = 9. 49 g/ml As stated before, to find the volume for all the measurements, wat er displacement was used. By this, the change in the water level (measured in ml) in the graduated cylinder was measured before and after each metal was added to determine its volume.For the bullet, it was determined that: o Mass = 12. 9 g o Volume = 2 ml o Density = 6. 45 g/ml Because the bullet was silver, it was determined that it was not made of copper and u to the fact that density wasn't similar to aluminum, it is likely that the bullet was made of steel and maybe another metal. Fiber and Hair Testing The next pieces of evidence that were analyzed were hair and fiber. The hair samples are a type of biological evidence while the fibers are a type of physical evidence.For these samples, microscopy was used, which allowed the researchers to examine and identify the fine features of each. The tables below include the collected data. Hair Color Features Brown Short, smooth Blonde Short, split Black Short, wiry Evidence Fiber Texture Blue Woven, denim-like Pink Tight, cylinder-like Tulle Wispy, feather-like Tulle and wispy/feather By comparing the evidence found at the crime scene to the samples collected from the suspect, it narrowed the possible suspects down to Olsen and Waffle since both of their fibers were found at the crime scene.Blood Testing The last task was to examine the blood samples collected from the suspects to the blood found at the crime scene. The blood samples were a type of biological evidence, but chemical reactions were used to determine the blood type. â€Å"Anti-A Serum,† â€Å"Anti-B Serum† and an â€Å"Anti-Re Serum† were used to test what type of blood he samples were and if they had an Re D antigen. Three drops of each suspect's blood, along with the blood collected at the crime scene, were placed into three different wells of a clean blood typing plate.Three drops of each serum were added to the three different wells and then stirred until they either reacted or remained inactive to the serum. A way to tell if the blood reacts to the serum is if it results in agglutination, or clumping. The results are listed in the table below. Suspect Reagent ABA-Re Blood Type Anti-A Serum Anti-B Serum Anti-Re Serum A+ Because some of the blood tests didn't react with the serum, the researchers had to SE the blood type information provided in the suspect's profile and then determine how the blood would have reacted if the tests worked properly.Analysis: Fingerprint Testing: After analyzing the data from the crime scene and the suspect sheets provided some educated assumptions can be made as to the possible perpetrator. The prints found at the scene of the crime had a loop configuration. Considering Licensee has an arch configuration, and Hutchins has a whorl configuration, they were ruled out as potential suspects. The suspects who possessed prints similar to those found at the scene were as follows: Daffy, Olsen, and Waffle.

AP/IB Biology Lab Assessment The effect of various fruit and vegetable cell membranes on their water potential Independent variable: Type of fruit or vegetable. (Produce used: Russet potatoes, Pascal celery, Gala apple, Navel orange, and Imperator carrot). The fruit or vegetable will be placed in six 56.7 gram cups, ranging with sucrose molarities of 0 (distilled water), 0.2, 0.4, 0.6, 0.8, 1.0, with 5 trials, leading to 30 cups for each produce variable. Dependent variable: The water potential of the produce, found by placing the produce in different molarities of sucrose and finding the isotonic state of the produce with a plotted line graph. Controlled variables: The controlled variables include: The type of produce used:†¦show more content†¦Qualitative Observations: At the start of the experiment, all produce appeared in normal condition, and all of the sucrose solutions had settled and looked normal, although the 0.2-molarity sucrose had a small amount of mold in the interior of the bottle. In the middle of the experiment, all produce samples were placed in their correct cups and were covered with aluminum foil. In order to keep the experiment controlled, we did not remove the aluminum foil until the produce had soaked for two days and was ready to be weighed. At the end of the experiment, we noticed a majority of the produce, especially apples, became soft and turgid in the solutions of distilled water, 0.2-molarity sucrose, and 0.4-molarity sucrose, as following to the fact that we noticed the majority of the produce gained weight (in grams) in those solutions. We also noticed produce, especially potatoes, in the solutions of 0.6-molarity sucrose, 0.8-molarity sucrose, and 1.0-molarity sucrose grew mold, which was peculiar because every potato sample in the 1.0-molarity sucrose lost an average of 25 percent in mass. Analysis of data: As shown by the graph and tables, the averages of percent change in mass showed the potato samples increased mass in the control, distilled water, and 0.2-molarity sucrose. The potato samples also lost considerable mass in 0.4-molarity sucrose, 0.6-molarity sucrose, 0.8-molarity sucrose, and 1.0-molarity sucrose. The data is

Organ Donation Shortage- Problem-Solution Essay - 2591 Words

Organ donation shortage Organ donation shortage When receiving a driver’s license in the United States, there is a section on the back in which it asks if the licensed driver would like to become an organ donor. Most people overlook this option. Nothing is really pushed forth for people wanting to become organ donors. Today in the U.S, thousands of people need organ transplants. Unfortunately, there is a growing shortage of donated organs. Many people die every year because there are not enough organs ready for transplant. Resulting, there is an extremely long waiting list of people hoping that they will be the next ones to get called to receive an organ. For a lot of those people, they die waiting on that list. If more people would†¦show more content†¦If this law was to be changed, there would be plenty of factors that went into financially compensating someone for the gift of an organ. Without potentially creating an organ market, there would be some deciding factors when it comes to paying each individual for t heir organ donation. Medical examiners would screen every potential donor to see if they are healthy, and financially stable enough to donate (Becker, 2009). This would eliminate the people who are just looking to gain money, not focused on the great gift they are giving. Solution Dr. Mortisugu, surgeon, says that organ donation is the â€Å"ultimate act of human kindness†. (Brody, 2007) So, why aren’t people donating? Let’s be honest, America is a selfish country. Many people are afraid of the surgery that comes along with donation. Although donation comes with a huge moral reward, it comes with no personal gain. Many professionals are saying that a good way to get people to donate is offer some sort of financial reward. Many Americans, are more willing to do something, if it will benefit them personally. That is a known fact. So, offer them something that will affect themselves, and many more people will hop on the donation bandwagon. If the donor’s donated organ is functional and available for transplant, it has been discussed that possibly paying for unexpected relatedShow MoreRelatedThe For An Anonymous Donor Program985 Words   |  4 PagesAdditionally, while there are solutions to the organ shortage problem, there are also a lternative solutions. The first alternative solution is to establish an anonymous donor program, where organs are donated and received from complete strangers. An advantage to an anonymous donor program would be that, it would eliminate the social bias and the medical bias. On the other hand, a disadvantage would be that, the recipient of the organ would know nothing about the donor. That could present issuesRead MoreOrgan Donation : Organ Organs1054 Words   |  5 PagesOrgan Donation Organ donation occurs when a failing or damaged organ, is replaced with a new organ, through a surgical operation. The two sources of organs for donation come from a deceased person and a living person. The organs that are received from a deceased person are called cadaveric organs.
