Extract of sample "Discuss the evidence, or lack of evidence, that exists to support the use of adrenaline (epinephrine) in cardiac arrest in pre-hospital setting (ambulance work)"

Download file to see previous pages patients outside of hospital had no substantially greater success or improved survival rates over medical technicians supplied with basic CPR skills and semi-automatic defibrillators (paraphrased from graphs. 1-3).
In a related study (Heart, 1997), researchers found results consistent with a continued skepticism over the use of adrenaline. According to this article, "Some emergency medical staff were authorised to give standard doses of adrenaline during the observational period. Adrenaline was given to 35% of patients and was associated with a significantly greater rate of restoration of spontaneous circulation and hospital admission. However, there was no significant difference in hospital discharge rates between the two groups. Thus adrenaline and its dosage during cardiac arrest remain controversial" (412-414).
It appears that when paramedics and other qualified emergency medical personnel give adrenaline to cardiac arrest patients in the field, it significantly improves the chance that the patient will live long enough to be admitted to the hospital, but it does not significantly improve the chance that patient will survive long enough to be discharged from the hospital. Adrenaline is good for buying the patient an extra few hours or an extra day filled with tests and possibly some invasive treatments. It may not be good for much more.
It should be pointed out that these findings may be more germane to patients who are found in ventricular fibrillation, rather than asystole. According to a study carried out in Sweden and reported in Resuscitation (1995a) Jun;29(3):195-201., "A large proportion of cardiac arrests outside hospital are caused by ventricular fibrillation. Although it is frequently used, the exact role of treatment with adrenaline in these patients remains to be determined.
AIM: "To describe the proportion of patients with witnessed out-of-hospital cardiac arrest found in ventricular fibrillation who survived and were discharged from ...Download file to see next pagesRead More

CARDIAC ARREST

... arrest. d)Drug abuse: The use of drugs and alcohol can be a very a risky factor for the healthy working of heart. “Teens and youngsters are more prone to use alcohol and drugs in an abusive manner. If it continues on a regular manner, the heart beat can escalate abnormally leading to cardiac arrest”(American medical Association). Test & Diagnosis The cardiac arrest is a situation arising without prior notice, and it demands emergency treatment in most cases. Doctors mostly are incapable of diagnosing sudden cardiac arrest by means of medical tests. On the contrary cardiac arrest is often diagnosed after everything happens.

... and they exist for various reasons. In summery cases there is no right to disclosure. What is the purpose of this? The rules under evidence should be interpreted in order to administer all proceedings in a fair manner, eliminate all unwarrantable delays and expenses, and helping the growth of evidence law by finishing and determining the fact of protecting a just determination. In a criminal case, the court can accept evidence provided that it shows someone, except the defendant as a source of the injury and the other physical evidences. The court may accept the evidence of victims provided by the defendant in order to prove the approval or if provided by the prosecutor and the evidences whose rejections it will violate are the defendant’s...

Evidence

... is essential, since it helps to determine the accuracy of the investigations, and thus determines any discrepancy that could have occurred in the suspect identification process (Federal Judicial Center, 35). For example, in the Weingarten, Gene’s: "The Police Couldn't Hide Their Lying Eyes” case, the evidence presented put the defendant at an absolute guilty position, because it had been determined that the $10 note serial number that the police officer used to purchase the drug matched the note that was found in the pocket of the defendant after he was arrested (Weingarten, n.d.). However, it is only through the disclosure of the investigation process, that a discrepancy in the description of the defendant, and the distance from where he...

Evidence work Evidence work Introduction Most laws and sta y provisions related to criminal justice draw a distinctive line between people who have attained the age of 18 years and those below this age1. These provisions typically treat people under the age of 18 years differently from adults. However, in most cases, when juveniles aged 17 years are taken into police custody for the purposes of questioning, they are considered as adults, thus treated as adults2. This is a notable anomaly in the eyes of provisions of the law, especially in terms of the treatment of detainees under criminal justice. Legal principles aim at promoting the rights of children throughout the administration of justice. This means that the legal system needs...

Obtaining Consent in Pre-Hospital Setting

... sexually transmitted disease. The Mental Hygiene law permits police officers to direct the removal of a person to a hospital in cases where he is likely to cause serious harm to himself or others. Any individual who is legally minor cannot give a valid informed consent to any sort of treatment and also he or she cannot legally refuse treatment. “Informed consent to participation in research is an important protector of potential subjects' rights and autonomy. Ethical research involving critically ill people is challenging because their medical condition often makes obtaining informed consent impossible. This is especially true in the prehospital setting, where additional barriers to obtaining informed consent exist. A recently published...

Forensic Evidence of Gunshot Residue

Proves are very crucial to many investigations, especially when attempting to reach a logical conclusion of whether or not the investigated shooting was done in self-defence, suicide, or in fact a homicide. Again, all the most up to date studies are also included in this researched literature being presented. The conclusion is in showing just how valuable of an asset these specific tests really are towards the outcome of numerous investigations from the past and in the present.
The materials that are found to make up gun powder residue and seemingly found to predominantly consist of a mixture including organic and non-organic substances are basically elemental metals, among other items. However, it has been determined by a nu...

A Warrant of Arrest Issued by a Court

Warrantless searches can be made where arrests are lawful and such searches are incident to such arrests. If the arrest was not lawful then the search becomes unlawful as well (Siegel & Senna 251). Generally, an arrest is lawful if the arresting officer is equipped with a warrant of arrest issued by a court with authority or jurisdiction, on the basis of a probable cause specifying the name or identity of the person to be arrested. However, even this doctrine is subject to the following exceptions: one, when a felony is being committed; second, when a felony has just been committed and the arresting officer or person has knowledge to reasonably believe that a person has committed it; third, all breaches of peace like riots and...

The Person and the Work of the Holy Spirit in John's Gospel

Prior to the real time events of the New Testament, the Old Testament revisited an idea which simply dictated that God was an entity and the only God was Ruah. The New Testament came with a series of events which changed everything from the cessation to offerings and sacrifices to an ideology of the Holy Trinity. Jesus is noted as being “anointed with the Holy Spirit” in John 1 32-34. This stands to reason that ther is a differentiation and somewhat autonomy between the three facets of the Holy Trinity. The Holy Trinity is of course, God, Jesus and the Holy Spirit. This is essentially a three in one or a unification of the elements of God. In John’s gospel, he seemingly avoids the dramatic details of the Holy Spi...

The Hard Work of UNHCR

Towards this direction, in the study of Atlani (2000) it is noticed that ‘there is a growing sense of urgency within international humanitarian aid agencies to intervene quickly when faced with organized violence stemming from war or armed conflict; from this perspective, the rape of refugees calls for prompt psychological intervention’ (Atlani, 2000, 435). In accordance with the above study, the provision of humanitarian aid has to be multidimensional. Apart from food, drugs and clothing, people in developing countries need to be supported psychologically – in many countries around the world, strong military conflicts are being developed on a daily basis.

Narrative Voice, Characterization, and Use of Settings in Catcher in the Rye and a Short History of Tractors in Ukrainian

The same is true of any writer. One is trying to get into a unique writing style, often without deliberate inclinations-- the style emerges of its own, -- but sometimes, the narrative voice as a writing technique is consciously employed by the writer. To start with, it is necessary for the writer to select which POV (point of view) to use.

The author’s persona of a fictional narrative can contribute to or mar the success of the story. Much depends on the plot of the story and how the author wishes to develop it. What is the emotional content of the story as a whole and how the individual emotional levels contribute to the total success of the story? There should not be any artificiality about the development of th...

The Use of Rhetoric in the Electronic Age

The rubric of the rhetorical theory is an extremely contested discipline with classical rhetoric theory focusing on the concept of rhetoric as a form of persuasion or an ideological perspective that asserts “rhetoric’s role in upholding power and domination” over the “general public” as the underlying basis of societal communication (Stacks & Salwen, 2008, p.240). However, the boundaries of the classical rhetorical theory have been challenged by cultural change, context and the permeation of alternative perspectives. 

In particular, the impact of the digital revolution and the growth of numerous multimedia streams on cultural norms has challenged classical theory propounding the fu...
