Filter by:The increase in stress hormone level and hyperventilation caused by the postoperative pain may contribute to the development of hypokalemia during postoperative period. Therefore, if the postoperative pain is well controlled by the IV-PCA,the plasma potassium level during the postoperative period may be not affected by stress response. The researchers tried to investigate the effect of IV-PCA on potassium regulation during the postoperative period.
Patients in critical care often require supplemental potassium chloride if levels in their blood are below acceptable level. Common practice is to administer a single dose of potassium chloride under controlled conditions via a drip, before checking if a further dose is required. The purpose of this study is to ensure that it is safe to administer potassium chloride continuously with the dose varied according to patient needs.
This clinical trial is designed to study the effect of the combination of licorice and hydrochlorothiazide on plasma potassium levels in volunteers. In one arm, 10 healthy volunteers will be given 32 grams of licorice a day together with a 25 mg dose of daily hydrochlorothiazide for 14 days. This combination is compared with 32 grams of licorice a day for 14 days given in the other arm. The study is a randomized, open-label cross-over trial. There is at least a 3-week wash-out between the arms. The hypothesis is that the combination of licorice and hydrochlorothiazide will cause hypokalemia. The main outcome measure is the change in the plasma level of potassium between the arms.
Kidney stone formation due to an excess of calcium in the urine is a common problem. It is treated with thiazide diuretics. These drugs often cause excessively low blood potassium levels that in turn require large doses of potassium supplements. These supplements are often large, unpleasant and easy to forget. We are trying the addition of spironolactone to these patients' medications to see if it allows them to take a lower dose of potassium.
