Pre-operative primary care Primary care can help optimise patients’ fitness before surgery by offering advice on smoking cessation buy 10 mg alavert amex, exercise and weight reduction best alavert 10 mg, and by optimising treatment of chronic conditions such as diabetes and anaemia (female <12 g. This may help increase survival, decrease peri-operative-1 morbidity and shorten the duration of hospital admission. This could take the form of accessing smoking cessation clinics, dietary advice and exercise regimens. Early referral by primary care and surgical teams for pre-operative management will increase efficiency. Nurse-led pre-operative assessment Pre-operative anaesthetic assessment is an extended role for nurses that has been shown to be safe and cost effective [3- 5]. These nurses usually work as an integral part of the pre- operative team and are a very important link between the patient and the entire peri-operative team. Nurses should work closely with the anaesthetists involved in the service and have good communication skills and links with the rest of the hospital. Their purpose is to contribute to the pre-operative preparation of all patients, to identify patients with a high peri-operative risk, to institute investigations and to refer to the anaesthetist, as well as to assess patients for suitability for day surgery. In addition, they will implement the various pre-operative protocols, including fasting and administration of regular medication, and are able to answer many of the patient’s questions about their anaesthetic. Protocols should empower the nurses to refer patients to relevant services such as echocardiography when there is a 9 history of a heart murmur, or pulmonary function tests for chest disease. These protocols should be written by senior anaesthetic staff and should be regularly reviewed and updated. In-clinic spirometry is useful and easy to perform, and may decrease the number of patients referred for formal pulmonary function tests. Pre-operative assessment nurses should co-operate closely with primary care services, particularly when administration of specific medication is required, such as subcutaneous anticoagulation or optimisation of diabetic treatment. Liaison with secondary care diabetes teams and medical outreach teams can be particularly helpful and may prevent unnecessarily long stays in hospitals, both pre- and post- operatively. It is important that pre-operative assessment nurses have readily available communication channels with pre-operative assessment anaesthetists; they should be able to discuss specific cases and receive feedback from the anaesthetist. The anaesthetist in the pre-operative assessment clinic Senior anaesthetists with a specialist interest in pre-operative assessment and optimisation should staff pre-operative assessment clinics with the number of sessions needed being dependent on the throughput of the hospital and its casemix. These anaesthetists should see all patients who are potentially at high risk, make an assessment of the risks and benefits of surgery and ensure that patients: • Are confident that they want surgery. The pre-operative assessment anaesthetist therefore needs to be skilled at assessing and managing these risks, and in communicating them both to the patient and to the treating surgeon. Consultant-to-consultant communication between anaesthetists, surgeons and critical care physicians is essential, particularly when the patient is high-risk and the benefits of surgery may be outweighed by the risks to the patient. Multidisciplinary meetings should help anaesthetic consultants identify and manage high-risk cases, particularly when major surgery is planned. Risk prediction can be used to guide the patient’s pre-operative care and determine whether the patient needs to see an anaesthetist in the pre-operative assessment clinic.
In that case generic 10mg alavert with mastercard, the direct reflex is intact but the consensual reflex is lost discount 10 mg alavert visa, meaning that the left pupil will constrict while the right does not. The Cranial Nerve Exam The cranial nerves can be separated into four major groups associated with the subtests of the cranial nerve exam. First are the sensory nerves, then the nerves that control eye movement, the nerves of the oral cavity and superior pharynx, and the nerve that controls movements of the neck. The olfactory, optic, and vestibulocochlear nerves are strictly sensory nerves for smell, sight, and balance and hearing, whereas the trigeminal, facial, and glossopharyngeal nerves carry somatosensation of the face, and taste—separated between the anterior two-thirds of the tongue and the posterior one-third. The oculomotor, trochlear, and abducens nerves control the extraocular muscles and are connected by the medial longitudinal fasciculus to coordinate gaze. Testing conjugate gaze is as simple as having the patient follow a visual target, like a pen tip, through the visual field ending with an approach toward the face to test convergence and accommodation. Along with the vestibular functions of the eighth nerve, the vestibulo-ocular reflex stabilizes gaze during head movements by coordinating equilibrium sensations with the eye movement systems. Motor functions of the facial nerve are usually obvious if facial expressions are compromised, but can be tested by having the patient raise their eyebrows, smile, and frown. Movements of the tongue, soft palate, or superior pharynx can be observed directly while the patient swallows, while the gag reflex is elicited, or while the patient says repetitive consonant sounds. The motor control of the gag reflex is largely controlled by fibers in the vagus nerve and constitutes a test of that nerve because the parasympathetic functions of that nerve are involved in visceral regulation, such as regulating the heartbeat and digestion. Movement of the head and neck using the sternocleidomastoid and trapezius muscles is controlled by the accessory nerve. The cranial nerves connect the head and neck directly to the brain, but the spinal cord receives sensory input and sends motor commands out to the body through the spinal nerves. Whereas the brain develops into a complex series of nuclei and fiber tracts, the spinal cord remains relatively simple in its configuration (Figure 16. From the initial neural tube early in embryonic development, the spinal cord retains a tube-like structure with gray matter surrounding the small central canal and white matter on the surface in three columns. The dorsal, or posterior, horns of the gray matter are mainly devoted to sensory functions whereas the ventral, or anterior, and lateral horns are associated with motor functions. In the white matter, the dorsal column relays sensory information to the brain, and the anterior column is almost exclusively relaying motor commands to the ventral horn motor neurons. The lateral column, however, conveys both sensory and motor information between the spinal cord and brain. Somatic senses are incorporated mostly into the skin, muscles, or tendons, whereas the visceral senses come from nervous tissue incorporated into the majority of organs such as the heart or stomach. The somatic senses are those that usually make up the conscious perception of the how the body interacts with the environment. Testing of the senses begins with examining the regions known as dermatomes that connect to the cortical region where somatosensation is perceived in the postcentral gyrus. To test the sensory fields, a simple stimulus of the light touch of the soft end of a cotton-tipped applicator is applied at various locations on the skin. The spinal nerves, which contain sensory fibers with dendritic endings in the skin, connect with the skin in a topographically organized manner, illustrated as dermatomes (Figure 16.
The level and criteria for the severity of psychoactive substance dependence are as follow: − Mild: Few purchase alavert 10 mg with visa, if any alavert 10mg online, symptoms in excess of those required to make the diagnosis, and the symptoms result in no more than mild impairment in occupational functioning or in usual social activities or relationships with others. A central descriptive characteristic of the dependence syndrome is the desire (often overpowering) to take substances. A return to substance use after a period of abstinence leads to a more rapid 25 Basic Concepts in Drug Addiction reappearance of other features of the syndrome than occurs with nondependent individuals. We also explain the factors that modulate the initiation and maintenance of drug use according to the classification of individual, micro social and macro social factors. Individual Factors Biological Aspects 26 José Pedro Espada and Daniel Lloret Irles Among individual factors related to substance use, genetic variables stand out the most. The relationship between parental drug use and the initiation into substance use by children has generated much controversy over whether the intergenerational transmission of drug abuse is due to biochemical or genetic factors or, in addition to biological vulnerability, other more determinant risk factors that are psychosocial or environmental in character. Most data come from studies focused on alcohol consumption and very few studies have been done in relation to other types of drugs. Physiological/biochemical studies suggest that sensation seeking and low risk avoidance predict the early initiation of alcohol use and later development of addiction. Similarly, in the case of marijuana, poor impulse control during childhood appears to predict the frequent use of this substance at the age of 18 (Shedler and Block, 1990). Studies with families indicate that alcoholic subjects are usually more likely to have a previous history of alcoholism among parents or siblings. These kinds of studies present significant methodological difficulties that hamper the generalization of results and limit their conclusions. Nevertheless, from research with children of alcoholics it has been concluded that these children are a risk population. Another area in which the contribution of genetic factors to the development of alcoholism has been investigated is the analysis of twins. In this area, there was an outstanding study conducted by Kaij (1960) with 174 pairs of Swedish male twins who had been reared separately from birth. The results indicated that when at least one member of each pair of twins was a proven chronic alcoholic, the concordance values for alcoholism were high, 71. Despite the discrepancies in the studies conducted in this area and the need for more evidence to confirm the assumptions, the idea that monozygotic twins may have a higher probability of being concordant for the development of alcoholism than dizygotic twins appears to hold up. Among biological factors, two interesting aspects stand out because of their implication in prevention programs in terms of the adjustment and enhancement of substance use protective factors in the adolescent population. The first is the differential influence of gender in young people in substance use and the second is age as a risk factor for substance use. These data underscore the idea that there appears to be no genetic vulnerability determined by the sex which leads subjects to use or to abstain from substance consumption.
These treatments raise plasma glucose concentrations only transiently alavert 10 mg lowest price, 29 and patients should be encouraged to eat as soon as they are alert in order to prevent a recurrence buy alavert 10mg with amex. Evidence implicating a causative role for chronic hyperglycemia in the development of macrovascular complications is less conclusive. Three major theories have been proposed to explain how hyperglycemia might lead to the chronic complications of diabetes mellitus. The development of chronic complications correlates with the duration of diabetes and glycemic control Ophthalmologic Complications of Diabetes Mellitus Diabetes mellitus is a leading cause of blindness in the working population in the developed world Blindness is primarily the result of progressive diabetic retinopathy and clinically significant macular edema. Intensive glycemic control will delay the development or slow the progression of diabetic retinopathy. There may be a transient, paradoxical worsening of established diabetic retinopathy, during the first 6 to 12 months of improved glycemic control. Regular, comprehensive eye examinations for all individuals with diabetes mellitus are required, and these should be performed by an experienced ophthalmologist. Other Ocular Problems Cataract Develop early and progress rapidly in diabetic subjects Glaucoma Ocular palsies Sudden visual loss Renal Complications of Diabetes Mellitus Diabetic Nephropathy • One of the commonest causes of end stage renal failure Nephropathy progresses through the following stages. The most common form of diabetic neuropathy is distal symmetric polyneuropathy often described as having a glove and stocking distribution. Diabetic polyradiculopathy is a syndrome characterized by severe disabling pain in the distribution of one or more nerve roots. Peripheral mononeuropathies or simultaneous involvement of more than one nerve (mononeuropathy multiplex) may also occur. Autonomic Neuropathy in diabetes can involve multiple systems, including: the cardiovascular, gastrointestinal, genitourinary, sudomotor, and metabolic systems. Autonomic neuropathies affecting the cardiovascular system cause a resting 32 tachycardia and orthostatic hypotension. Hyperhidrosis of the upper extremities and anhidrosis of the lower extremities result from sympathetic nervous system dysfunction. Anhidrosis of the feet can promote dry skin with cracking, which increases the risk of skin ulceration. Autonomic neuropathy may reduce counterregulatory hormone release, leading to an inability to sense hypoglycemia appropriately (hypoglycemia unawareness, thereby subjecting the patient to the risk of severe hypoglycemia and complicating efforts to improve glycemic control. One should consider other possible causes of neuropathy before ascribing signs and symptoms to be due to diabetic neuropathy as other causes of neuropathy may present in a similar manner. Diabetic foot disease Different types of diabetic tissue damage interact and combine in the feet, giving a wide variety of lesions ranging from relatively harmless dysaesthesiae to fulminating infections and widespread ulceration and gangrene. Factors that play important roles in the pathogenesis of diabetic foot ulcers include, • Neuropathy o Predisposes patient to repetitive trauma to the feet • Reduction in blood flow o Delays wound healing o Serves as a good medium for bacterial multiplication • Deformity in the feet o This leads to abnormal foot mechanics with misdistribution of pressure over parts of the feet.

All patients suspected of having cysticercosis should be referred to higher centers for better diagnosis and management. The spores are able to survive cooking, and if the cooked food (meat and poultry) is not cooled enough, they will germinate. General After completing this module the learner will be able to assess and manage cases of food borne disease. Specific After reading this module you will be able to: ¾ Assess the patient with food borne disease ¾ Make the Nursing diagnosis ¾ Plan the Nursing intervention ¾ Implement the planned intervention ¾ Evaluate the outcomes of the intervention 3. Subjective Data • Onset and duration of the disease (14) • History of ingestion of contaminated food (food with unusual odor or taste, uncooked vegetables, raw meat etc. Nursing Diagnosis Based on the classification of the food borne diseases and findings of the nursing assessment the following actual and potential nursing diagnosis can be made: i. Poisoning related to the ingestion of contaminated food with chemical poisons, poisonous plants and toxins. Knowledge deficit about possible causes of the disease and preventive measures related to lack of information. Risk for fluid volume deficit related to vomiting and increased loss of fluids and electrolytes from gastro-intestinal tract. Establish goals for the nursing intervention • To remove or inactivate the poison before it is absorbed. Establish expected outcomes The patient: • Reveals reduced/ no effects of the poisoning chemical, poisonous plant or toxins • Reports less pain • Reports a decrease in the frequency of diarrheal stools • Tolerates small frequent feeding • Verbalizes concerns and fears • Reports the different causes and preventive measures of food borne disease 78 • Has no observable signs and symptoms of fluid balance • Prevents spread of the infection to others D. Reducing / eliminating the effects of the poisonous chemical, poisonous plant or toxins ¾ Attain control of the air way, ventilation, and oxygenation • Prepare for mechanical ventilation if respirations are depressed. Use gastric emptying procedures as; the following may be used: • Syrup of ipecac to induce vomiting in the alert patient. Administer the specific chemical antagonist or physiologic antagonist as early as possible to reverse or diminish effects of the toxin. Poisons may excite the central nervous system or the patient may have seizures from oxygen deprivation. Measures to Relief Pain To ease anal irritation (pains) caused by diarrhea, clean the area carefully and apply a repellent cream, such as petroleum jelly, warm sitz baths and application of witch hazel compresses can also soothe irritation. Establishing a Regular Pattern of Bowel Elimination and Maintaining Nutritional Balance ¾ Administer medications, as ordered, correlate dosages and routes with the patient’s meals and activities. If the patient is receiving a potassium supplement, be especially alert for the development of hyperkalemia (14,28,29). Reducing Anxiety ¾ An opportunity is provided for the patient to express fears and worry about being embarrassed by lack of control over bowel elimination. The patient is encouraged to be sensitive to body clues that warn of impending urgency (abdominal cramping, hyperactive bowel sounds). Special absorbent underwear, which will protect clothes if there is accidental fecal discharge, may be helpful.
