Central nervous system (cns) symptoms include irritability, lethargy, and drowsiness. Muscle weakness is one o the main clinical eatures with predominant involvement o proximal lower limb muscles. Importantly, an ascending weakness with preservation o muscle stretch re exes may be encountered with potassium levels below 2.5 mmol/l.43 t is weakness may progress to include the diaphragm and accessory muscles and mani est as neuromuscular respiratory ailure.44 furthermore, as potassium release rom muscles regulates muscle blood ow during exercise, severe hypokalemia can cause muscle ischemia leading to rhabdomyolysis and myoglobinuria.45 cardiac mani estations include q prolongation and arrhythmias such as atrial brillation, orsades de pointes, ventricular tachycardia, and ventricular brillation. Prominent u waves may be seen on electrocardiogram (ecg). Renal abnormalities associated with hypokalemia include impaired concentrating ability, increased ammonia production, increased bicarbonate reabsorption, altered sodium reabsorption, and hypokalemic nephropathy (tubular atrophy and interstitial nephritis with hypokalemia o prolonged duration). Reatment is based on the management o the underlying mechanism and appropriate potassium replacement. Caution must be used when replacing potassium in patients with end-stage renal ailure on dialysis because overcorrection may occur. Similar caution should be exercised when replacing potassium in patients who develop hypokalemia during induction o therapeutic hypothermia because reversal o the ionic translocation between intracellular and extracellular compartments takes place during rewarming, and consequently there is a risk o hyperkalemia and cardiac arrhythmias during that treatment phase. Hyperkalemia x increased potassium intake, increased potassium release rom cells, and reduced excretion o potassium are the mechanisms by which hyperkalemia occurs. Most commonly it is encountered in patients with renal ailure (especially in patients on dialysis) due to decreased renal elimination o potassium. However, medication-induced hyperkalemia is also commonly encountered—speci cally excess potassium supplementation, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and succinylcholine can all cause hyperkalemia through increased intake, reduced elimination, and increased cellular release, respectively. Furthermore, hyperkalemia can also be seen with acidemia as the result o cellular shi. Neurological mani estations include an ascending paralysis that is o en preceded by paresthesias mimicking gbs.46 cardiac abnormalities are the most eared mani estation o hyperkalemia and usually occur a er the serum potassium has increased above 7.0 mmol/l. Conduction block and arrhythmias may occur, including sinus arrest, asystole, and ventricular tachycardia and brillation. In the kidney, hyperkalemia blocks the excretion o ammonia and thus hyperammonemia is possible. Electrocardiography can demonstrate peaked waves and the hyperkalemic brugada pattern (pseudo-right bundle branch block with coved s segment elevation in ≥ 2 precordial leads), although the presence and resolution o these signs are not reliable indicators o disease severity or resolution.

help on simplest form homework 8 »» treatment desired outcomes desired outcomes of treatment are to restore normal heart rate and alleviate patient symptoms. Pharmacologic therapy  treatment of sinus bradycardia is only necessary in patients who become symptomatic. If the patient is taking any medication(s) that may cause symptomatic sinus bradycardia, they should be discontinued whenever possible. If the patient remains in sinus bradycardia after drug discontinuation and after five half-lives of the drug(s) have elapsed, then the drugs(s) can usually be excluded as the etiology of the arrhythmia. In certain circumstances, however, discontinuation may be undesirable, even if the drug may be the cause of symptomatic sinus bradycardia. For example, if the patient has a history of mi or hfref, discontinuation of a β-blocker may be necessary in the short term but undesirable long term because β-blockers have been shown to reduce mortality and prolong life in patients with those diseases, and benefits of therapy with β-blockers outweigh the risks associated with sinus bradycardia. In this situation, clinicians and patients may elect to implant a permanent pacemaker to allow continuation of therapy with β-blockers. Acute treatment of the symptomatic and/or hemodynamically unstable patient with sinus bradycardia includes administration of the anticholinergic drug atropine, which should be given in doses of 0. 5 mg intravenous (iv) every 3 to 5 minutes. The maximum recommended total dose of atropine is 3 mg. 11 atropine is generally used as a method of achieving acute symptom control while awaiting placement of a transcutaneous or transvenous pacemaker. Where necessary, transcutaneous pacing can be initiated during atropine administration. Atropine should be used cautiously in patients with myocardial ischemia or mi because increasing heart rate and myocardial oxygen demand may aggravate ischemia or extend the infarct. In patients with hemodynamically unstable sinus bradycardia unresponsive to atropine, transcutaneous pacing may be initiated.

thesis dedication for dead parents Mcgraw-hill, 2014:127, with permission. A chapter 6  |  heart failure  83 desired therapeutic outcomes the goals of therapy for ahf are to. (a) correct the underlying precipitating factor(s). (b) relieve the patient’s symptoms. (c) improve hemodynamics. (d) optimize a chronic oral medication regimen. And (e) educate the patient, reinforcing adherence to lifestyle modifications and the drug regimen. The ultimate goal for a patient hospitalized for ahf is return to a compensated hf state and discharge to the outpatient setting on oral medications. Only through aggressive management to achieve all of these goals will a patient’s prognosis be improved and future hospitalizations for acute decompensations be prevented. Removal or control of precipitating factors is essential for an optimal response to pharmacologic therapy. Relief of symptoms should occur rapidly to minimize length of hospitalization. Although a rapid discharge from the hospital is desirable, a patient should not be discharged before ensuring that he or she is in a euvolemic, or nearly euvolemic, state with a body weight and functional capacity similar to before the acute decompensation. Oral agents such as β-blockers, ace inhibitors or arbs, and aldosterone antagonists should be initiated as soon as possible during the hospitalization.
