Transmission can be ■ parenteral (most body fluids) ■ sexual ■ (possibly) through insect bites (Pratt 1995) purchase cialis jelly without prescription erectile dysfunction drugs with the least side effects. Chronic carriers rarely develop infection (Raeside 1996) cialis jelly 20 mg amex erectile dysfunction drugs at walmart, but can spread infection (Pratt 1995) discount cialis jelly 20mg otc erectile dysfunction doctor specialty. Hepatitis C usually recurs following transplantation, but most patients remain asymptomatic. Hepatitis D complicates hepatitis B infection, making fulminant hepatic failure more likely. In Europe and North America, hepatitis D is primarily transmitted through drug injection; elsewhere infection is usually sexual (Pratt 1995). Hepatic failure 379 Complications Liver dysfunction affects most other major systems of the body. The description below is reductionist, and specific management of other systems is covered in other chapters. Cerebral oedema provokes intracranial hypertension, impairing cerebral perfusion pressure (see Chapter 22). Prolonged effects from exogenous sedation may delay recovery and make assessment difficult; debate continues on whether to avoid sedating patients with hepatic failure. Whichever medical practice is followed, nurses should actively assess the level of sedation and effects of drugs. Normal sleeping patterns may be reversed, with patients remaining awake overnight. Treatment should optimise cerebral perfusion pressure by reducing intracranial pressure while maintaining mean arterial pressure (see Chapter 22). Persistent intracranial hypertension (above 25 mmHg) may be reversed with mannitol. Chronic failure compounds dyscrasias from ■ splenatomegaly (from portal hypertension), which reduces platelet counts ■ depressed bone marrow function (from alcoholism or paracetamol) which reduces erythropoiesis. Gastrointestinal and respiratory (although not cerebral) bleeds frequently occur (Hawker 1997a). Replacement factors, such as vitamin K (Cowley & Webster 1993) or blood components, may be prescribed. Intensive care nursing 380 The liver contributes significantly to immunity through production of complements (see Chapter 23) and Kupffer cells—specialised reticuloendothelial cells in the liver which destroy any bacteria translocating from the gut. Asepsis, high standards of infection control and continuing vigilance can minimise risks to patients; early detection of infection enables early treatment. Blood from the liver soon reaches pulmonary vessels so that surviving gut bacteria readily cause pulmonary infection; increased capillary permeability enables pulmonary oedema formation, and possible shunting. As suction raises intracranial pressure, patients should be preoxygenated and duration and number of passes should be minimised (see Chapter 22). Suction may also cause trauma, so that catheters withdrawn should be observed for blood (type, amount) as well as sputum (type, colour, amount). Hepatopulmonary syndrome occurs in up to 30 per cent of patients with endstage failure (Isaac & Manji 1997). Pathology is unclear; there is no specific treatment and resolution can be spontaneous, but mortality remains high. Hepatopulmonary syndrome is an indication for liver transplantation (Isaac & Manji 1997. Cardiovascular compromise is caused by ■ hypovolaemia ■ vasodilation ■ increased capillary permeability ■ reduced cardiac return. As prolonged hypotension predisposes to multiorgan dysfunction, nurses should closely assess and monitor cardiovascular function. Inotropes will probably be needed, although may have little effect if sympathetic pathways are damaged. Stress responses (see Chapter 3) increase blood and intracranial pressure, and so patients should be nursed in quiet environments with minimal sensory stimulation. There is no detectable histological change to renal tissue, and kidneys resume normal function following hepatic transplantation (Hinds & Watson 1996); without transplantation, mortality exceeds 90 per cent (Hinds & Watson 1996). Unlike acute tubular necrosis, relatively normal sodium reabsorption and urine concentration is maintained during hepatorenal syndrome. The liver has more than 500 metabolic functions, and so hepatic failure causes complex disorders. Electrolyte disorders from hepatic hypofunction are often compounded by renal and capillary epithelial changes. Reduced free water clearance can dilute electrolyte concentrations, causing hyponatraemia and hypokalaemia (Sussman 1996). Prolonged malnourishment (especially with alcoholism), vomiting and nasogastric drainage may compound hypokalaemia, while dehydration (e. Electrolyte imbalances have varied systemic effects, including dysrhythmias from hypokalaemia and oedema formation from hyponatraemia. Hepatic failure 381 Metabolic acidosis may occur from ■ hypoperfusion (anaerobic metabolism) ■ renal impairment ■ gastric acid loss (vomiting, aspiration) (Adam & Osborne 1997) Impaired toxin metabolism and clearance increases sensitivity to, and effects of, many drugs and metabolites. With chronic failure, hepatocellular necrosis prevents glycogenolysis, which causes potential hypoglycaemia (Lockhart-Wood 1996), necessitating frequent blood sugar monitoring and probably glucose supplements. Artificial livers The development of artificial livers has been slow and problematic, but shortage of donor livers prompted experiments with xenoperfusion. Cadaver and baboon livers have achieved extracorporeal support for up to 75 days (Conlin 1995), although immunologie intolerance makes xenoperfusion impractical (Sussman 1996). Temporary support is possible from hepatocytes grafted onto semipermeable hollow-fibre devices (visually similar to those used for haemofiltration), which provide support until transplantation (Fristoe et al. Nurses should encourage families to express their needs Intensive care nursing 382 and emotions, but it may be necessary to involve counselling or other services. Liver function affects many other organs and systems, and so the care of patients with liver dysfunction requires a range of knowledge and skills. Intracranial hypertension, a major complication of hepatic failure, is discussed further in Chapter 22. Further reading Hawker is a leading authority on hepatic failure; her chapter (1997a) is an accessible and useful source. Langley and Pain (1994) discuss some of the options for medical treatment, while Stanley et al. Artnal and Wilkinson (1998) give a case study of fulminant failure from paracetamol. Clinical scenario Fabio Galvani is a 26-year-old male who has recently completed a six-month backpacking trip to southeast Asia. Since his return he has been feeling increasingly unwell with nausea, vomiting, fever with influenza-like symptoms. He was admitted to hospital for investigations after behaving in a confused and agitated manner.

This chapter outlines the effects of physiological ageing on major body systems before focusing on wider social and attitudinal issues discount 20mg cialis jelly with visa valium causes erectile dysfunction. Such aims can be easily lost in events of physiological crises and technological intervention order 20mg cialis jelly fast delivery erectile dysfunction washington dc. Chronological ageing is statistically simple and clear purchase generic cialis jelly erectile dysfunction doctors in south jersey, and is adopted by much medical literature (especially quantitative research), but it is usually medically arbitrary, failing to recognise each person’s uniqueness and individuality. Nurses should therefore approach each person as an individual, rather than as chronological stereotypes. Intensive care nursing 122 Physiological ageing is individual to each person, influenced by multiple factors such as gender, genetic inheritance, lifestyle and social class (Black et al. Ageing almost inevitably brings decline in function; but rates of decline vary between systems and individuals. Reserve function (the differ-ence between actual level of function and minimum function needed for homeostasis) provides a barrier against disease; progressive reduction in reserve function increases likelihood of chronic disease in later years (e. As reserve function of all systems (variably) declines, multiple pathology and effects become more likely (Kilner & Janes 1997); so reduced renal and hepatic function prolong metabolism (and so effect) of drugs and toxins. Underlying chronic conditions (including chronic pain such as arthritis) are more common among older people. Arthritis may be visually apparent, but individual assessment may identify other needs, enabling nurses to avoid inflicting accidental pain. Physiological effects With age, cardiovascular homeostasis slows and baroreceptors become less sensitive (Rebenson-Piano 1989), impairing response to sudden hypotension. Cross-linking of collagen fibres causes calcium deposit formation (Herbert 1991), reducing penetrability of arterial tunica to lipids (e. Lipid accumulation forms plaque, enabling platelet adhesion and aggregation within the arterial lumen (Todd 1997). Thrombi and emboli can cause ischaemia and major organ failure (cerebrovascular accidents, myocardial infarction, renal failure, pulmonary embolus). Myocardial collagen cross-linking limits ventricular filling, so reducing stroke volume. Most respiratory insufficiency in older people is caused by ageing of airway tissue, chemical damage (especially smoking and environmental pollutants) and muscle atrophy. Average pulmonary function is halved between 30 and 90 years of age (Hough 1996); decreased expiratory recoil reduces vital capacity and lung compliance. Pulmonary circulation also suffers atherosclerosis, increases pulmonary artery pressures. Older people are more frequently malnourished than younger people (Doyle 1990) due to factors such as poverty, poor mobility, maldentition, lack of facilities or constipation. Gastrointestinal tract atrophy makes villi shorter and broader, reducing bowel fluid absorption (Herbert 1991). The liver is a major source of body heat, and so reduced hepatic function contributes to impaired thermoregulation. Central nervous system degeneration progresses throughout life so that older patients are more likely to suffer: ■ organic brain disease (e. However, confusion may be caused by ■ absence of sensory aids (glasses, hearing aid) ■ hypoxia ■ toxic metabolites ■ alcohol (alcoholism is increasing among older people (Godard & Gask 1991)). Therefore, apparent ‘confusion’ should be holistically assessed, and care planned to meet individual needs. Reality orientation can provoke aggression (sensory imbalance); psychiatry has developed a range of alternative approaches, such as validation therapy (Feil 1993), that seeks to empower rather than control people, but most approaches rely on verbal responses, limiting their value for intubated, sedated patients. As skin ages, epidermis flattens, with loss of papillae (Herbert 1991) so that epidermal and dermal layers peel apart more easily, causing pressure sores from sheering (see Chapter 12). Capillary loss reduces oxygen, nutrients and hydration; skin becomes dryer, more brittle and prone to tearing with delayed healing. Most pressure sores occur in people over 70 years of age (Mihissin & Houghton 1995), hence the weighting for age on Waterlow and other assessment scales. Pressure area aids can reduce the incidence of pressure sores, but optimising endogenous factors (nutrition, perfusion) reduces risks. Muscular and skeletal atrophy contribute to weakness (which delays weaning from ventilation). Mortality is easily measured, but quality of life is a more valuable (if more subjective) measure of outcome. Conflicting research and practice makes healthcare for the critically ill older adults into a covert lottery. Ageism ‘Ageism’, the ‘notion that people cease to be people…by virtue of having lived a specific number of years’ (Comfort 1977:35), leads to ■ prejudice ■ stereotyping ■ negatives attitudes (Redfern 1991) and may be overt (e. Today’s elders grew up before the National Health Service existed, and so remember a very different society (and social values)—doctors (and nurses) then were presumed always to know best. Therefore, the beliefs and values of the older patients may differ significantly from those of the nurses caring for them—and different generational values may cause misunderstandings. Bereavement, social mobility and physical immobility are more likely to leave older people isolated, depriving them of the social supports (families, friends) that younger people usually have; friends and family may treat the older person as a burden. Psychological isolation can become self-fulfilling, encouraging older people to adopt child-like dependent behaviour and/or appear confused. Problems encountered by older people using hospital services can persist after leaving the department; specialised assessment forms for older people (e. De Beauvoir (1970) is highly readable, providing challenging sociological perspectives. Some useful, albeit largely quantitative, medical studies have been published in recent years, including Castillo-Lorente et al. The effect of physiological ageing on older patients in intensive care is discussed by Kilner and Janes (1997). Clinical scenario Frank Hobson is a very socially active and independent 84-year-old retired civil servant. Note the main age-related physiological changes and how these are incorporated into planning postoperative care. Immunocompromise and infection are often part of a complex pathological process; related material can be found in other chapters, especially chapters 9, 39 and 40. Exogenous infection is usually through contact (staff, procedures, equipment), but can also be airborne. Immunity develops with age and exposure to pathogens so that children are at greater risk of infection (e. Highly invasive equipment used with critically ill patients provides multiple entry sites for microorganisms so that benefits should be weighed against infection risks. Enteral tubes and infected feeds facilitate microorganisms entry into the gut, bypassing many nonspecific immune defences (e. Feeds standing for prolonged times at room temperature provide ideal media for bacterial growth. Forty-five per cent of patients stayed over 5 days, with infection rates tripling after 3– 4 days. Patients staying longer were usually sicker, but exposure to secondary infections compounded mortality.
