This can be caused by long-term administration of saline infusions which can result in the loss of magnesium and calcium quality 250 mg terramycin. Diuretics safe 250 mg terramycin, certain antibiotics order 250mg terramycin free shipping, laxatives, and steroids are drug groups that promote magnesium loss. Hypomagnesemia also enhances the action of digitalis and can cause dig- italis toxicity. Patients who have hypomagnesemia may exhibit no signs and symptoms until the serum level approaches 1. Signs of severe hypomagnesemia include tetany-like symptoms caused by hyperexcitability (tremors, twitching of the face), ventricular tachycardia that leads to ventricular fibrillation, and hypertension. Treatment for hypomagnesemia includes: • Administering intravenous magnesium sulfate in solution slowly. Use an infusion pump to prevent rapid infusion that might result in cardiac arrest. Keep calcium gluconate available for emergency reversal of hypermagne- semia as a result of overcorrecting hypomagnesemia. Phosphorus Phosphate is the primary anion inside the cell and plays a key role in the func- tion of red blood cells, muscles, and the nervous system. Phosphate is also involved the acid–base buffering and is involved with metabolizing carbohy- drates, proteins, and fats. As the serum calcium concentration increases, the concentration of serum phosphorus decreases and conversely as serum phosphorus increases, serum calcium decreases. Abnormally high levels of serum phosphate are usually caused by kidney malfunction. Hyperphosphatemia Hyperphosphatemia is the condition exhibited by a patient whose serum phos- phate is greater than 4. Unlike hyperkalemia and hypermagnesemia, acute hyperphosphatemia causes few sudden problems. The major effect is to cause hypocalcemia and tetany if serum phosphate rises too rapidly. The treatment for acute hyperphosphatemia is administration of phosphate binding salts, calcium, magnesium, and aluminum although aluminum is avoided in renal failure. Treatment for hyperphosphatemia can include: • Restricting foods and drinks (carbonated soda) high in phosphate. Hypophosphatemia Hypophosphatemia occurs in a patient’s whose serum phosphate is less than 2. The nurse should monitor the patient for the following signs and symptoms of hypophosphatemia: • Bone and muscle pain. Electrolytes are positive and negatively charged particles that generate electrical impulses that, among other things, cause our muscles to contract. Fluids and electrolytes are stored in two compartments: intracellular (in- side the cell) and extracellular (outside the cell). There are three types of fluid concentrations: iso-osmolar (same concentration), hypo-osmolar (low concentration), and hyper- osmolar (high concentration). There are five key electrolytes: potassium, sodium, calcium, magnesium, and phosphorus. Diseases and treatment of diseases are two factors that can cause fluids and electrolytes to become imbalanced. The healthcare professional must quickly identify the signs and symptoms of the imbalance and then take steps to restore the balance between electrolytes and fluids. What is determined by the concentration of electrolytes and other solutes in water?

Diagnosis of Intoxication The terms alcohol intoxication and drunkenness are often used inter- changeably buy terramycin 250mg without a prescription. However purchase terramycin 250 mg without prescription, a distinction between these terms is justified because people may exhibit behavioral changes associated with drunkenness when they believe they have consumed alcohol but actually have not (164) buy 250 mg terramycin amex. Thus, the diagnostic features of alcoholic intoxication developed by the American Psy- chiatric Association include a requirement that there must have been recent ingestion of alcohol (Table 16) (165). Table 17 Pathological States Simulating Alcohol Intoxication • Severe head injuries • Metabolic disorders (e. This is particularly important when assessing an intoxi- cated detainee in police custody. Indeed, the doctor’s first duty in examining such individuals should be to exclude pathological conditions that may simu- late intoxication (154) (Table 17), because failure to do so may lead to deaths in police custody (166). Alcohol Dependence Alcohol abuse and dependence is a major risk factor for serious health, social, and economic problems (167). Early identification of those who are dependent on alcohol increases the possibility of successful treatment, and 314 Stark and Norfolk brief intervention by the forensic physician seems both feasible and accept- able (124,168). Although not yet validated in police custody, brief interven- tions show a high acceptance among drinkers in licensed premises (169). However, obtaining accurate and reliable information about a person’s drinking habits can be extremely difficult because heavy drinkers tend to underestimate or deliberately lie about their alcohol consumption (170). The main features dif- ferentiating alcohol dependence from alcohol abuse are evidence of toler- ance, the presence of withdrawal symptoms, and the use of alcohol to relieve or avoid withdrawal. However, there is no need to treat those who simply abuse alcohol and who do not have a history of alcohol withdrawal. Alcohol Withdrawal Many alcoholics develop symptoms of withdrawal when in custody. When alcohol intake is abruptly stopped on incarceration, the com- pensatory changes give rise to signs and symptoms of withdrawal (176). The severity of the symptoms depends mainly on the amount and duration of alco- hol intake, although other factors, such as concurrent withdrawal from other drugs, like benzodiazepines, may contribute to the clinical picture (177). Uncomplicated Alcohol Withdrawal This is the most frequent and benign type, usually occurring some 12–48 hours after alcohol intake is reduced, although it can develop as early as 6 hours after drinking has stopped. The essential features are a coarse tremor of the hands, tongue, and eyelids, together with at least one of the following: Substance Misuse 315 • Nausea and vomiting. If symptoms are mild, it is safe to recommend simple observation, but significant tremor and agitation will usually require sedation. The drugs of choice are long-acting benzodiazepines, which will not only treat alcohol with- drawal symptoms but will also prevent later complications (178). The starting dosages depend on the severity of the withdrawal, but 20 mg of chlordiazep- oxide, or 10 mg of diazepam, both given four times a day, will generally be appropriate (179). Usually the benzodiazepines should not be started until such time as the blood alcohol level has reached zero (180). However, detained persons with marked alcohol dependence may develop withdrawal symptoms before this point is reached. In these circumstances, it is both safe and reasonable to initiate therapy when the blood alcohol level has reached 80 mg/100 mL or thereabouts. Alcohol Withdrawal Delirium The essential diagnostic feature of this disorder is a delirium that devel- ops after recent cessation of or reduction in alcohol consumption. Tradition- ally referred to as delirium tremens, this withdrawal state typically begins 72–96 hours after the last drink, so it is uncommon within the normal span of detention in police custody.

The problems are similar in all three conditions: muscle weakness (including respiratory), underlying hypotension and bradycardia with potentially excessive inappropriate episodes of hypertension and tachycardia. Nursing patients with these conditions can be labour intensive and stressful; they need care and support with many activities of living, while minimising complications significantly improves recovery and survival. Management of all three conditions centres on ■ attempts to remove underlying causes ■ prevention of complications ■ system support. While there is some research evidence, practice varies between units; some approaches described below are anecdotal rather than evidence-based. While the literature is consistent on incidence, it is inconsistent about possible gender, age, racial and seasonal prevalence. Immune system dysfunction results in T-lymphocyte migration to peripheral nerves causing inflammation oedema (Ross 1993) and myelin destruction (Desforges 1992), creating lesions (especially in spinal nerves and near dorsal root ganglia) (Waldock 1995) and the progressive destruction of the nodes of Ranvier. This, in turn, causes ascending motor and sensory paralysis, resulting in diffuse muscle weakness. Prolonged artificial ventilation is often needed, and many units favour early tracheostomy. Steroids, once used widely, are not recommended in Desforges’ (1992) literature review. Circulating mediators may be removed through plasma exchange (Fulgham & Wijdicks 1997), plasmapheresis (Hund et al. If basement membrane remains intact, recovery begins once Schwann cells’ mitosis remyelinates damaged nerves (usually 2–4 weeks (Skowronski 1997)). Death is usually caused by respiratory or cardiac arrest (McMahon-Parkes & Cornock 1997), so that the prevention of complications improves survival. Muscle weakness and autonomic dysfunction can cause: ■ pain from nerve dysfunction, exacerbated by touch (Coakley 1997) and anxiety, which is usually worse in the evening (Mirski et al. Neurological pathologies 371 ■ hyper salivation and loss of gag reflex from autonomic dysfunction necessitate oral suction to prevent aspiration. Prophylactic beta blockers can control hypertension (Hinds & Watson 1996), although Fulgham and Wijdicks (1997) recommend caution with vasoactive drugs. Routine atropine (Hinds & Watson 1996) or sequential pacing may prevent bradycardias. Two per cent of deaths are caused by pulmonary emboli (Coakley 1997); cerebral and myocardial infarction may also occur. Thrombosis risk can be reduced by • frequent changes of position • prophylactic subcutaneous heparin (Winer 1994) • thromboembolytic stockings (Winer 1994) • early and aggressive rehabilitation, including active and passive exercises ■ limb weakness, ascending from distal to proximal muscles, affecting hands, feet or both. Passive exercises may prevent contractures (Winer 1994) and promote venous return. Paralytic ileus may necessitate parenteral nutrition, but if possible enterai feeding should be used (McMahon-Parkes & Cornock 1997); paralytic ileus may be bypassed through jejunostomy. Antidepressants are often useful, but should not become a substitute for active human nursing (e. Patients with critical illness neuropathy, autonomic dysreflexia and other prolonged disease processes may suffer similar psychological problems. Intensive care nursing 372 Critical illness neuropathy (′acute axonal neuropathy′) Critical illness neuropathy, acute axonal neuropathy (Hund et al. Autonomic dysreflexia (′hyperreflexia′) The autonomic nervous system controls homeostasis (including vasodilation/constriction and heart rate). Spinal injury severs normal inhibitory pathways, so that parasympathetic compensation occurs only above lesions, with exaggerated sympathetic responses below. Most patients with spinal injuries above T6 develop autonomic dysreflexia at least 4 weeks, and often 6 months, following injury; it can occur with injuries above T10 (Keely 1998).
