Diabetes insipidus requires fluid and electrolyte replacement buy lansoprazole 15 mg without a prescription chronic gastritis flare up, along with the administration of vasopressin purchase discount lansoprazole line gastritis diet ôđčâ, to replace and slow the urine output generic lansoprazole 30mg line gastritis diet çĺíčň. Assessing respiratory function is essential purchase lansoprazole 30 mg otc gastritis healing symptoms, because even a small degree of hypoxia can increase cerebral ischemia. The respiratory rate and pattern are monitored, and arterial blood gas values are assessed frequently. The nurse must be alert to the development of complications; all assessments are carried out with these problems in mind. Chart 61-2 provides an overview of the nursing management of the patient who has undergone intracranial surgery. Seizures are a potential complication, and any seizure activity is carefully recorded and reported. Restlessness may occur as the patient becomes more responsive, or restlessness may be caused by pain, confusion, hypoxia, or other stimuli. The endotracheal tube is left in place until the patient shows signs of awakening and has adequate spontaneous ventilation, as evaluated clinically and by arterial blood gas analysis. Some degree of cerebral edema occurs after brain surgery; it tends to peak 24 to 36 hours after surgery, producing decreased responsiveness on the second postoperative day. Intraventricular drainage is carefully monitored, using strict asepsis when any part of the system is handled. Overview of Nursing Management for the Patient after Intracranial Surgery Postoperative Interventions Nursing Diagnosis: Risk for ineffective breathing pattern related to postoperative cerebral edema Goal: Achievement of adequate respiratory function Establish proper respiratory exchange to eliminate systemic hypercapnia and hypoxia, which increase cerebral edema. Nursing Diagnosis: Risk for imbalanced fluid volume related to intracranial pressure or diuretics Goal: Attainment of fluid and electrolyte balance Monitor for polyuria, especially during first postoperative week; diabetes insipidus may develop in patients with lesions around the pituitary or hypothalamus. Nursing Diagnosis: Disturbed sensory perception (visual/auditory) related to periorbital edema and head dressings Goal: Compensate for sensory deprivation; prevent injury Perform supportive measures until the patient can care for self. Temperature control may be impaired in certain neurologic states, and fever increases the metabolic demands of the brain. Assess temperature of extremities, which may be cold and dry due to impaired heat-losing mechanisms (vasodilation and sweating). The patient is asked about the factors or events that may precipitate the seizures. The nurse determines whether the patient has an aura before an epileptic seizure, which may indicate the origin of the seizure (eg, seeing a flashing light may indicate that the seizure originated in the occipital lobe). Observation and assessment during and after a seizure assist in identifying the type of seizure and its management. Planning and Goals The major goals for the patient may include prevention of injury, control of seizures, achievement of a satisfactory psychosocial adjustment, acquisition of knowledge and understanding about the condition, and absence of complications. Nursing Interventions Preventing Injury Injury prevention for the patient with seizures is a priority. If the type of seizure the patient is having places him or her at risk for injury, the patient should be lowered gently to the floor (if not in bed), and any potentially harmful items nearby (eg, furniture) should be removed. Patients for whom seizure precautions are instituted should have pads applied to the side rails while in bed. Cooperation of the patient and family and their trust in the prescribed regimen are essential for control of seizures. The nurse emphasizes that the prescribed antiseizure medication must be taken on a continuing basis and that drug dependence or addiction does not occur. Periodic monitoring is necessary to ensure the adequacy of the treatment regimen, to prevent side effects, and to monitor for drug resistance (Rho et al. In an effort to control seizures, factors that may precipitate them are identified, such as emotional disturbances, new environmental stressors, onset of menstruation in female patients, or fever (Rho et al. The patient is encouraged to follow a regular and moderate routine in lifestyle, diet (avoiding excessive stimulants), exercise, and rest (sleep deprivation may lower the seizure threshold). An additional dietary intervention, referred to as the ketogenic diet, may be helpful for control of seizures in some patients (Stafstrom & Rho, 2004). This high-protein, low-carbohydrate diet is most effective in children whose seizures have not been controlled with two antiepileptic medications, but it is sometimes used for adults who have had poor seizure control (Stafstrom & Rho, 2004). Photic stimulation (bright flickering lights, television viewing) may precipitate seizures; wearing dark glasses or covering one eye may be preventive. Because seizures are known to occur with alcohol intake, alcoholic beverages should be avoided. Improving Coping Mechanisms The social, psychological, and behavioral problems that frequently accompany epilepsy can be more of a disability than the actual seizures. Epilepsy may be accompanied by feelings of stigmatization, alienation, depression, and uncertainty. The patient must cope with the constant fear of a seizure and the psychological consequences (Rho et al. Children with epilepsy may be ostracized and excluded from school and peer activities. These problems are compounded during adolescence and add to the challenges of dating, not being able to drive, and feeling different from other people. Adults face these problems in addition to the burden of finding employment, concerns about relationships and childbearing, insurance problems, and legal barriers. Family reactions may vary from outright rejection of the person with epilepsy to overprotection. As a result, many people with epilepsy have psychological and behavioral problems. Counseling assists the patient and family to understand the condition and the limitations it imposes. Nurses can improve the quality of life for patients with epilepsy by teaching them and their families about symptoms and their management (Bader & Littlejohns, 2004). Providing Patient and Family Education Perhaps the most valuable facets of care contributed by the nurse to the person with epilepsy are education and efforts to modify the attitudes of the patient and family toward the disorder. The person who experiences seizures may consider every seizure a potential source of humiliation and shame. This may result in anxiety, depression, hostility, and secrecy on the part of the patient and family. Ongoing education and encouragement should be given to patients to enable them to overcome these reactions. The patient with epilepsy should carry an emergency medical identification card or 376 wear a medical information bracelet. The patient and family need to be educated about medications as well as care during a seizure. Monitoring and Managing Potential Complications Status epilepticus, the major complication, is described later in this chapter. The patient and family are instructed about side effects and are given specific guidelines to assess and report signs and symptoms that indicate medication overdose. A complete pharmacologic profile should be reviewed with the patient to avoid interactions that either potentiate or inhibit the effectiveness of the medications. Promoting Home and Community-Based Care Teaching Patients Self-Care Thorough oral hygiene after each meal, gum massage, daily flossing, and regular dental care are essential to prevent or control gingival hyperplasia in patients receiving phenytoin (Dilantin).

Often buy generic lansoprazole 15 mg on-line gastritis pathophysiology, many body systems are impaired as a result of the stroke discount lansoprazole online acute gastritis symptoms uk, and conscientious care and timely interventions can prevent debilitating complications generic lansoprazole 30 mg amex gastritis diet menu plan. During and after the acute phase purchase lansoprazole cheap online diet untuk gastritis akut, nursing interventions focus on the whole person. In addition to providing physical care, the nurse encourages and fosters recovery by listening to the patient and asking questions to elicit the meaning of the stroke experience. Improving Mobility and Preventing Joint Deformities A patient with hemiplegia has unilateral paralysis (paralysis on one side). When control of the voluntary muscles is lost, the strong flexor muscles exert control over the extensors. The arm tends to adduct (adductor muscles are stronger than abductors) and to rotate internally. The elbow and the wrist tend to flex, the affected leg tends to rotate externally at the hip joint and flex at the knee, and the foot at the ankle joint supinates and tends toward plantar flexion. Because flexor muscles are stronger than extensor muscles, a posterior splint applied at night to the affected extremity may prevent flexion and maintain correct positioning during sleep. A pillow is placed under the arm, and the arm is placed in a neutral (slightly flexed) position, with distal joints positioned higher than the more proximal joints (ie, the elbow is positioned higher than the shoulder and the wrist higher than the elbow). This helps to prevent edema and the resultant joint fibrosis that will limit range of motion if the patient regains control of the arm (Fig. Positioning the Hand and Fingers The fingers are positioned so that they are barely flexed. The hand is placed in slight supination (palm faces upward), which is its most functional position. If the upper extremity is flaccid, a volar resting splint can be used to support the wrist and hand in a functional position. If the upper extremity is spastic, a hand roll is not used, because it stimulates the grasp reflex. In this instance a dorsal wrist splint is useful in allowing the palm to be free of pressure. Spasticity, particularly in the hand, can be a disabling complication after stroke. Researchers reported that repeated intramuscular injections of botulinum toxin A into wrist and finger muscles reduced upper limb spasticity after stroke, resulting in significant and sustained improvements in muscle tone. To place a patient in a lateral (side-lying) position, a pillow is placed between the legs before the patient is turned. To promote venous return and prevent edema, the upper thigh should not be acutely flexed. The patient may be turned from side to side, but if sensation is impaired, the amount of time spent on the affected side should be limited. A small pillow or a support is placed under the pelvis, extending from the level of the umbilicus to the upper third of the thigh (Fig. This position helps to promote hyperextension of the hip joints, which is essential for normal gait and helps prevent knee and hip flexion contractures. The prone position also helps to drain bronchial secretions and prevents contractural deformities of the shoulders and knees. During positioning, it is important to reduce pressure and change position frequently to prevent pressure ulcers. Establishing an Exercise Program The affected extremities are exercised passively and put through a full range of motion four or five times a day to maintain joint mobility, regain motor control, prevent contractures in the paralyzed extremity, prevent further deterioration of the neuromuscular system, and enhance circulation. Exercise is helpful in preventing venous stasis, which may predispose the patient to thrombosis and pulmonary embolus. If tightness occurs in any area, the range-of-motion exercises should be performed more frequently (see Chapter 11). The patient is observed for signs and symptoms that may indicate pulmonary embolus or excessive cardiac workload during exercise; these include shortness of breath, chest pain, cyanosis, and increasing pulse rate with exercise. Frequent short periods of exercise always are preferable to longer periods at infrequent intervals. Improvement in muscle strength and maintenance of range of motion can be achieved only through daily exercise. The patient is encouraged and reminded to exercise the unaffected side at intervals throughout the day. It is helpful to develop a written schedule to remind the patient of the exercise activities. The patient can be taught to put the unaffected leg under the affected one to assist in moving it when turning and exercising. Flexibility, strengthening, coordination, endurance, and balancing exercises prepare the patient for ambulation. Usually an active rehabilitation program is started as soon as the patient regains consciousness. The patient is first taught to maintain balance while sitting and then to learn to balance while standing. If the patient has difficulty in achieving standing balance, a tilt table, which slowly brings the patient to an upright position, can be used. Tilt tables are especially helpful for patients who have been on bed rest for prolonged periods and have orthostatic blood pressure changes. If the patient needs a wheelchair, the folding type with hand brakes is the most practical because it allows the patient to manipulate the chair. The chair should be low enough to allow the patient to propel it with the uninvolved foot and narrow enough to permit it to be used in the home. When the patient is transferred from the wheelchair, the brakes must be applied and locked on both sides of the chair. A chair or wheelchair should be readily available in case the patient suddenly becomes fatigued or feels dizzy. As the patient gains strength and confidence, an adjustable cane can be used for support. Generally, a three- or four-pronged cane provides a stable support in the early phases of rehabilitation. Preventing Shoulder Pain As many as 70% of stroke patients suffer severe pain in the shoulder that prevents them from learning new skills. Shoulder function is essential in achieving balance and performing transfers and self-care activities. Three problems can occur: painful shoulder, subluxation of the shoulder, and shoulderâ€“hand syndrome. A flaccid shoulder joint may be overstretched by the use of excessive force in turning the patient or from overstrenuous arm and shoulder movement. To prevent shoulder pain, the nurse should never lift the patient by the flaccid shoulder or pull on the 394 affected arm or shoulder. If the arm is paralyzed, subluxation (incomplete dislocation) at the shoulder can occur as a result of overstretching of the joint capsule and musculature by the force of gravity when the patient sits or stands in the early stages after a stroke.
Undergoing the recovery stroke beneath the mucus layer prevents retrograde mucus transport (Figure 9 order 30mg lansoprazole with mastercard gastritis high fiber diet. They are packed at a density of 6â€“8 cilia per ÎĽm2 and cannot move without affecting neighbouring cilia purchase lansoprazole now gastritis natural cures. In order to perform an unhindered beat cycle the movement of each cilium is slightly out of phase with that of its neighbor generic 15mg lansoprazole gastritis diet íůăĺăčó, leading to a phenomenon termed â€ściliary metachronyâ€ť purchase lansoprazole 30 mg fast delivery gastritis symptoms and chest pain. Metachrony results solely from hydrodynamic coupling between adjacent cilia and provides the necessary cooperation within a field of cilia to permit them to transport mucus. Each cilium is bounded by an evagination of the plasma membrane and, as shown diagrammatically (Figure 9. Each outer doublet microtubule consists of an A subfiber which is circular in cross-section, and an incomplete B subfiber, which is C-shaped in cross-section. The inner and outer dynein arms of the A subfiber project towards the B subfiber of the adjacent microtubule. Since the microtubules are constrained at the ciliary tip, it is possible to imagine how the sliding of microtubules on one side of the cilium might cause the cilium to bend. How such sliding is translated into a full beat cycle is still the subject of extensive research. A wide number of agents are able to alter the rate of ciliary beating; this can either be via a non-specific, toxic effect, e. However, data concerning the role of cyclic guanosine 5â€˛-phosphate-dependent protein phosphorylation on ciliary beat frequency are conflicting. Increases in the intracellular concentration of Ca2+ ([Ca2+] ) increases ciliary beat frequency possibly via i protein phosphorylation induced by calcium/calmodulin kinase. Ciliated cells also respond to mechanical stimulation by increasing their beat frequency, an effect which spreads to surrounding cells (5â€“7 cells in all directions) and is mediated by an increase in [Ca2+]. Such intercellular signaling provides the opportunity for cooperative cellular activity which would be advantageous to the ciliated epithelium in its efforts to transport mucus. Airway cilia may be able to upregulate their beat frequency in response to an increase in the mucus load. As with most sites of drug absorption, the bioavailability of a drug is affected by the area available for absorption, the contact time between the drug and the absorption site, metabolism of the drug prior to and during absorption and the pathology of the absorbing tissue. The area available for absorption is enhanced2 by: â€˘ the convolutions of the turbinates, and â€˘ the microvilli present on the surface of the ciliated and unciliated cells of the respiratory epithelium. However, the effective surface area for absorption is influenced by the type of dosage form from which the drug is administered, as described below. Molecules (% loss) Degradation 0â€“15 0â€“5 Clearance a 0â€“30 20â€“50 Deposition (anterior loss) 10â€“20 10â€“20 Health status and environment 10â€“20 10â€“40 Membrane permeability ab 0â€“30 20â€“50 Mucus layer <1 <1 adepends on excipients bdepends on physicochemical characteristics of the drug, e. This property facilitates its physiological role in heat exchange and also potentially, drug absorption. The rich blood supply means that drugs absorbed via the nasal route have a rapid onset of action, which can be exploited for therapeutic gain. In the nasal cavity this is influenced by the rate at which the drug is cleared from the absorption site by mucociliary clearance and by metabolism. While the mucociliary clearance of deposited particles is advantageous if the particles are likely to be hazardous, the clearance of a deposited drug is clearly not beneficial if it prevents absorption. The site of deposition in the nasal cavity profoundly affects the rate of mucociliary clearance of a drug moiety: â€˘ Particles deposited on ciliated regions (for example, the turbinates) of the mucosa are immediately available for clearance. As described above, clearance of the bulk of the mucus from the nose to the nasopharynx occurs over 10â€“20 minutes. This is probably because most of the spray has deposited on non-ciliated regions of the nasal cavity. Deposition site; â–ˇ Turbinates; â–˛ Nasopharynx â—Ź The implications of this for drug absorption are that administration of a drug as drops may only be suitable if the drug molecule is rapidly absorbed. Those drug molecules which diffuse across the nasal epithelium more slowly will need a longer contact time and may be better administered as sprays. The absorption rate of certain drugs may be so slow that therapeutically active plasma levels are not attained. Such conditions include rhinitis, the common cold, hayfever, sinusitis, asthma, nasal polyposis, Sjogrenâ€™s and Kartagenerâ€™s syndromes. In addition, environmental factors such as humidity, temperature and pollution can also affect the rate of nasal clearance. The common cold consists of two distinct phases: mucus hypersecretion, followed by nasal congestion. It has been shown that during the former phase, less than 10% of a dose administered as a nasal spray will remain in the nasal cavity after 25 minutes. In contrast, almost all the administered dose will still be present at the site of deposition up to 90 minutes after administration during the nasal congestion phase. This would clearly lead to unpredictable absorption of an administered drug which would be unacceptable for a potent drug with a narrow therapeutic window. The inclusion of a vasoconstrictor such as oxymetazoline in the formulation might relieve such symptoms and provide more reproducible drug absorption. This would be likely to affect drug absorption but not necessarily in a reproducible manner. It has been suggested that the low bioavailabilities of some nasally administered peptides results from their enzymatic degradation in the nasal cavity. The nasal mucosa and fluids have been shown to possess a variety of exopeptidases and endopeptidases (see Section 1. The actions of intracellular enzymes will not be significant if the peptide is absorbed by the paracellular route (see Section 9. Small peptides are relatively resistant to the action of endopeptidases but their activity is significant for large peptides. Although enzymatic activity is present in the nasal cavity, this activity is generally lower than the enzymatic activity of the gastrointestinal tract, making this route an attractive alternative to the oral delivery of enzymatically labile drugs such as therapeutic peptides and proteins. These enzymes are capable of metabolizing inhaled pollutants into reactive metabolites which may induce nasal tumors. Antibodies are secreted in the nasal cavity and may be found in high concentrations in the mucus layer where they are able to neutralize antigens presented to the nasal mucosa. Foreign proteins delivered to the body are capable of eliciting an immune response and indeed antibodies have been detected in nasal secretions in response to the intranasal administration of insulin. Clearly this situation is undesirable since the therapeutic molecule will undergo degradation and the patient is likely to suffer with symptoms associated with allergic diseases such as hayfever. It is possible that pharmaceutical excipients which cause inflammation of the nasal cavity might exacerbate such reactions. One method by which mucus protects the nasal epithelium is by acting as a physical barrier and respiratory mucus has been reported to retard the diffusion of water and a range of Î˛-lactam antibiotics used to treat respiratory infections. However, other studies have shown that antibodies (150â€“970 kDa) are able to diffuse through cervical mucus relatively unimpeded; these latter studies tend to suggest that the diffusion barrier presented by mucus in the nasal cavity would be insignificant. Positively charged drug molecules can bind to mucus glycoproteins via electrostatic interactions with the large number of negatively charged sialic acid and sulfate ester residues.
