Electrolytes potassium

Concentrated electrolytes (potassium chloride, potassium phosphate, and sodium chloride greater than 0.9%) should not be stored in patient care areas as a patient safety measure. Serum magnesium levels do not correlate well with total body magnesium stores. For this reason, magnesium supplementation is often given empirically to critically ill patients.

Compounds that dissociate to a large extent (70-100%) into ions when dissolved in water are said to be strong electrolytes, while compounds that dissociate to only a small extent are weak electrolytes. Potassium chloride and most other ionic compounds, for instance, are largely dissociated in dilute solution and are thus strong electrolytes. Acetic acid, by contrast, dissociates to the extent of about 1.3% in a 0.10 M solution and is a weak electrolyte. As a result, a 0.10 M solution of acetic acid is only weakly conducting. 

Spironothiazid is a diureteic and an ALDOSTERONE antagonist. This means that it suppresses the water retaining actions of the hormone ALDOSTERONE while lowering water retention by lowering electrolytes (potassium, sodium, and calcium). The advantage of the combination is that the potassium absorption effect by the spironolactone can be mediated by the hydrochlorthiazide. Because of this, some of the potassium loss side effects can be avoided. This is probably a safer choice than LASIX though any diuretic use should be medically monitored. Thiazides also lead to a lower loss of calcium. 

As hydrogen fluoride is removed from the electrolyte, potassium fluoride is precipitated in the bottom of the cell, the bath becomes viscous, and the temperature necessary to keep it molten rises. When a temperature of 280 to 300°C. becomes necessary, the loss of hydrogen fluoride by evaporation is excessive and the electrolyte should be regenerated. It can be ladled out of the cell into a cold copper dish and broken into small pieces when solidified. 

Alkaline (AFC) These are use by NASA on the manned space missions, and operate well at about 80 °C. They use alkaline electrolyte, potassium hydroxide, and can generate electricity with the efficiency up to 70 %.

Frequent monitoring of serum electrolytes (potassium and magnesium) with adequate hydration and ion supplementation corresponding to amounts lost by kidneys concomitant to AmB therapy provides an effective intervention for prophylaxis of AmB-induced renal toxicify [119]. 

Filtered sodium is reabsorbed at the proximal tubules, the Loop of Henle, distal tubules, or in the collecting tubules. Diuretics influence tubules closest to the glomeruli, causing natriuresis (sodium loss in the urine). Diuretics cause loss of other electrolytes (potassium, magnesium, chloride, bicarbonate). Diuretics that promote potassium excretion are called potassium-wasting diuretics or potassium-sparing diuretics. 

Figure 4-2 An experiment to demonstrate the presence of ions in solution. Two copper electrodes are dipped into a liquid in a beaker. When the liquid contains significant concentrations of ions, the ions move between the electrodes to complete the circuit (which includes a light bulb), (a) Pure water and sugar are nonelectrolytes, (b) A solution of a weak electrolyte, acetic acid (CH3COOH) it contains low concentrations of ions, and so the bulb glows dimly, (c) A solution of a strong electrolyte, potassium chromate (K2Cr04) it contains a high concentration of ions, and so the bulb glows brightly.

Whenever possible, potassium supplementation should be administered by mouth. Three salts are available for oral potassium supplementation chloride, phosphate, and bicarbonate. Potassium phosphate should be used when patients are both hypokalemic and hypophosphatemic potassium bicarbonate is most commonly used when potassium depletion occurs in the setting of metabolic acidosis. Potassium chloride, however, is the primary salt form used because it is the most effective treatment for the common causes of potassium depletion (i.e., diuretic-induced and diarrhea-induced hypokalemia). Because diarrhea and diuretics such as hydrochlorothiazide and furosemide promote net potassium and chloride losses, supplementation with potassium chloride repletes both electrolytes. Potassium chloride can be administered in either tablet or liquid formulations (Table 50-4). The liquid forms are generally less expensive however,... 

Similarly, aqueous K2Cr04 also behaves as a strong electrolyte. Potassium chromate contains the K" and CrO ions, so an aqueous solution of potassium chromate (which is prepared by dissolving solid K2Cr04 in water) contains these separated ions. 

Increased risk of toxicity with drugs that alter serum electrolytes (potassium -depleting diuretics, corticosteroids, thiazide and loop diuretics, amphotericin B, quinidine, amiodarone). Blockers of p adrenergic receptors, calcium channels, or acetylcholinesterase increase risk of complete AV block. Drugs which alter Gl absorption may alter bioavallabillty. 

B. Other useful laboratory studies include electrolytes (potassium), BUN, creatinine, phosphoms, arterial blood gases or pulse oximetry, and continuous EGG monitoring. Measure serum potassium levels frequently.

Overtreatment of sodium imbalance could result in the opposite, sodium imbalance, as well as fluid and electrolyte (potassium) imbalances, if care is not exercised. 

Although no histological changes are detectable in the serous glands of patients with cystic fibrosis, the sweat, lacrimal, salivary, and stomach glands excrete excessive amounts of electrolytes (potassium and sodium chloride). The volume of sweat, however, is within normal limits.

Lead-acid batteries contain the electrolyte sulfuric acid (H2SO4). NiCd batteries contain mostly the electrolyte potassium hydroxide (KOH). Both electrolytes create burns and can cause injury to the skin. In the event of electrolyte entering the eyes burns of the cornea with permanent damage are possible (Table 6.7). For first aid wash with plenty of water and obtain medical attention.

If K for a standard solution of a reference electrolyte is known, l/A - the cell constant - may be calculated from an observed resistance using the cell in question and the standard electrolyte. Potassium chloride is the accepted standard for which accurately determined values of K at different concentrations and temperature in aqueous solution are available. Once the cell constant is known the conductivity of any electrolyte may be determined from its measured resistance using Equation (4.3). The essential circuit is shown in Fig. 4.1.
