Treating infection The antibiotic era has witnessed many microorganism mutations cheap 20mg micardis amex heart attack trey songz lyrics, creating resistance to successive generations of (increasingly expensive and toxic) antibiotics generic 20 mg micardis mastercard hypertension facts. Drug companies face escalating investment costs for products increasingly difficult to market, and potentially soon obsolete; Gould (1994b) reports that one-half of drug companies are stopping or seriously reducing antibiotic production. The Chief Medical Officer for Scotland has predicted that by 2020 healthcare will run out of antibiotics (cited by Amyes & Thomson 1995). Such statements may appear sensationalist, but they emphasise the need to reorientate from relying on drugs to preventing and controlling infection. Antibiotics remain useful adjuncts to treatment, but will probably become progressively less effective. The inappropriate use of antibiotics has created more pathogenic, resistant organisms (Parke & Burden 1998), and so unnecessary use is actively discouraged (House of Lords Select Committee on Science and Technology 1998). Early onset pneumonia (from aspiration during trauma) is usually antibiotic- sensitive, but late onset pneumonia (ventilator-associated pneumonia) is usually resistant (Rello et al. Monoclonal antibodies are cloned and genetically engineered human Blymphocytes (Eburn 1993). Heat Moisture Exchangers) should be changed according to manufacturers’ instructions (normally daily); catheter mounts should be changed at the same time as humidifiers Infection control 135 ■ invasive techniques and disconnection of intravenous lines should, when possible, avoid times of dust disturbance (e. Antibiotics and other medical treatments can reduce morbidity and mortality, but preventing infection is humanly (and usually financially) preferable. Hygiene is helped by adequate and appropriate facilities, including sufficient washbasins, aprons and unit guidelines and protocols. All multidisciplinary team members should be actively involved in making decisions, but nurses have an especially valuable role in coordinating and controlling each patient’s environment. Problems from infection are likely to escalate; continuing vigilance and care can minimise infection risks and the spread of microorganisms. Further reading Articles on infection control frequently appear in specialist and general journals. Taylor’s (1978) classic article on handwashing is recommended; issues for nursing practice regularly appear in many general nursing journals. She was transferred from elderly care facilities with rapidly deteriorating respiratory function, copious mucopurulent sputum and atelectasis. Catherine’s previous respiratory tract infections had been treated with oral Amoxycillin (beta lactam class of antibiotics). Issues related to infection control are included in end-of-chapter scenarios in chapters 39 and 40. Chapter 16 Ethics Introduction The value of ethics for healthcare has been increasingly recognised: critical care often adds greater focus and poignancy to ethical dilemmas. Ethics raises questions rather than provides answers; dilemmas have more than one solution. Each person has values; some are formed or shared with peer groups, others are individual. Different values may cause conflict (for example, the care versus cure debate of Chapter 1). Active questioning enables evaluation of beliefs underpinning practice, helping nurses to understand others’ perspectives, but solutions necessarily remain individual. Increasing public expectations (and litigation) of healthcare, and changes within nursing (increased autonomy, responsibility and accountability) are reflected by greater emphasis on ethics in nursing education. A high public and media profile makes intensive care nursing a much-scrutinized area. This chapter provides a basis both for practice and for the remainder of this book; professional development can usefully be extended through discussion with colleagues and further study. This chapter describes the four main ethical principles identified by Beauchamp and Childress (1994): ■ autonomy ■ non-maleficence ■ beneficence ■ justice and the three main ethical theories identified by Rumbold (1993): ■ duty-based ■ goal-based ■ rights-based Other authors may give different arrangements, wording or additional theories and principles. Ethical principles provide a framework with which to work through dilemmas, identifying what is harmful, what is good and what is just.

We are not told whether he had a fever discount 80mg micardis mastercard arrhythmia yahoo answers, and the white cell count should be measured discount 40 mg micardis free shipping heart attack sam. If this does seem the likely diagnosis it would be best to treat him where he is, if this is safe and possible. There is every likelihood that he will return to his previous state if the urinary tract infection is confirmed and treated appropriately, although this may take longer than the response in temperature and white cell count. Treatment should be started on the pre- sumption of a urinary tract infection, while the diagnosis is confirmed by microscopy and culture of the urine. The most likely organism is Escherichia coli, and an antibiotic such as trimethoprim would be appropriate, although resistance is possible and advice of the local microbiologist may be helpful. From the confusion point of view he should be treated calmly, consistently and without confrontation. If medication is necessary, small doses of a neuroleptic such as haloperidol or olanzapine would be appropriate. In dementia, there is an acquired global impairment of intellect, memory and personality, but consciousness is typically clear. She had last seen him at 8 pm the evening before when they came home after Christmas shopping. When she came to see him the next afternoon she found him unconscious on the floor of the bathroom. There was a family history of diabetes mellitus in his father and one of his two brothers. His girlfriend had said that he had shown no signs of unusual mood on the previous day. He had his end of term examinations in psychology coming up in 1 week and was anx- ious about these but his studies seemed to be going well and there had been no problems with previous examinations. The first part of the care should be to ensure that he is stable from a cardiac and respiratory point of view. Blood gases should be measured to monitor the oxy- genation and ensure that the carbon dioxide level is not high, suggesting hypoventilation. The family history of diabetes raises the possibility that his problem is related to this. One would expect a slower development with a history of thirst and polyuria over the last day or so. Hypoglycaemia comes on faster but would not occur as a new event in diabetes mellitus. Other metabolic causes of coma such as abnormal levels of sodium or calcium should be checked. A neurological problem such as a subarachnoid haemorrhage is possible as a sudden unexpected event in a young person. Where the level of consciousness is so affected, some localizing signs or subhyaloid haemorrhage in the fundi might be expected. Despite the lack of any warning of intent beforehand, drug overdose is common and the question of avail- ability of any medication should be explored further. If there is any suspicion of this then levels of other drugs which might need treat- ment should be measured, e. The other possibility in somebody brought in unconscious is that they are suffering from carbon monoxide poisoning. The fact that it is winter and he was found in the bathroom where a faulty gas-fired heater might be situated increases this possibility. Patients with carbon monoxide poisoning are usually pale rather than the traditional cherry-red colour associated with carboxyhaemoglobin. Papilloedema can occur in severe carbon monoxide poisoning and might account for the swollen appearance of the optic discs on funduscopy. He was treated with high levels of inspired oxygen and made a slow but full recovery over the next 48 h. Mannitol for cerebral oedema and hyperbaric oxygen are considerations in the management. The problem was traced to a faulty gas water heater which had not been serviced for 4 years. His conscious level is decreased but he is rousable to command and there are no focal neurological signs.

The axes remind us that when making a diagnosis we must look at the complete picture buy micardis 20mg free shipping arrhythmia death, including biological purchase 40mg micardis otc heart attack chords, personal, and social-cultural factors. For instance, the disorder of mental retardation can be classified as mild, moderate, or severe. In school, he cannot stay in his seat for very long and he frequently does not follow instructions. Zack has poor social skills and may overreact when someone accidentally bumps into him or uses one of his toys. At home, he chatters constantly and rarely settles down to do a quiet activity, such as reading a book. Symptoms such as Zack‘s are common among 7-year-olds, and particularly among boys. Boys mature more slowly than girls at this age, and perhaps Zack will catch up in the next few years. One possibility is for the parents and teachers to work with Zack to help him be more attentive, to put up with the behavior, and to wait it out. But many parents, often on the advice of the child‘s teacher, take their children to a psychologist for diagnosis. Other studies have also pointed to environmental factors, such as mothers‘ smoking and drinking alcohol during pregnancy and the consumption of lead and food additives by those who are affected (Braun, Kahn, Froehlich, [23] Auinger, & Lanphear, 2006; Linnet et al. Jared is able to maintain eye contact and enjoys mixing with other children, but he cannot communicate with them very well. He often responds to questions or comments with long-winded speeches about trucks or some other topic that interests him, and he seems to lack awareness of other children‘s wishes and needs. Jared‘s concerned parents took him to a multidisciplinary child development center for consultation. Here he was tested by a pediatric neurologist, a psychologist, and a child psychiatrist. The pediatric neurologist found that Jared‘s hearing was normal, and there were no signs of any neurological disorder. He diagnosed Jared with a pervasive developmental disorder, because while his comprehension and expressive language was poor, he was still able to carry out nonverbal tasks, such as drawing a picture or doing a puzzle. Based on her observation of Jared‘s difficulty interacting with his peers, and the fact that he did not respond warmly to his parents, the psychologist diagnosed Jared with autistic disorder (autism), a disorder of neural development characterized by impaired social interaction and communication and by restricted and repetitive behavior, and in which symptoms begin before 7 years of age. The psychologist believed that the autism diagnosis was correct because, like other children with autism, Jared, has a poorly developed ability to see the world from the perspective of others; engages in unusual behaviors such as talking about trucks for hours; and responds to stimuli, such as the sound of a car or an airplane, in unusual ways. The child psychiatrist believed that Jared‘s language problems and social skills were not severe enough to warrant a diagnosis of autistic disorder and instead proposed a diagnosis of Asperger‘s disorder, a developmental disorder that affects a child’s ability to socialize and Attributed to Charles Stangor Saylor. The symptoms of Asperger‘s are almost identical to that of autism (with the exception of a delay in language development), and the child psychiatrist simply saw these problems as less extreme. Clearly there is something wrong with their child, but even the experts cannot agree on exactly what the problem is. Diagnosing problems such as Jared‘s is difficult, yet the number of children like him is increasing dramatically. Disorders related to autism and Asperger‘s disorder now affect almost 1% of [25] American children (Kogan et al. The milder forms of autism, and particularly Asperger‘s, have accounted for most of this increase in diagnosis. Although for many years autism was thought to be primarily a socially determined disorder, in which parents who were cold, distant, and rejecting created the problem, current research suggests that biological factors are most important. The heritability of autism has been estimated [26] to be as high as 90% (Freitag, 2007). Scientists speculate that autism is caused by an unknown genetically determined brain abnormality that occurs early in development. It is likely [27] that several different brain sites are affected (Moldin, 2003), and the search for these areas is being conducted in many scientific laboratories.
