hypokalemia/hypoxia

Human ether-a-go-go-related gene (hERG) encodes the pore-forming subunit of the rapidly activating delayed rectifier potassium channel (I_Kr) important for repolarization of cardiac action potentials. Drug-induced disruption of hERG channel function is a main cause of acquired long

We report a case of bronchial asthma attack with lactic acidosis and hypokalemia in a patient receiving high-dose inhalation of procaterol hydrochloride. A 28-year-old man was transferred to our hospital because of adynamia, nausea and dyspnea. He had used inhaled procaterol hydrochloride with a

A 93 year-old hypertensive woman was found to have severe hypokalemia (as low as 1.3 mEq/L) and developed paralysis of the all extremities associated with metabolic alkalosis, hypoxemia, hypercapnea, extremely high levels of creatine phosphokinase (up to 9280 U/L), myoglobin and myoglobinuria

Acute hypoxia has been reported to induce a decrease in aldosterone levels despite no change or increases in plasma renin activity and ACTH. Converting enzyme inhibition and/or mild hypokalemia have been suggested as possible mechanisms for this dissociation. We studied 15 patients with chronic

This case study describes the investigation of the sudden, unexpected death of a young, slightly hypertensive woman. She had a previous history pf serious hypokalemic-induced cardiac dysrhythmias associated with diuretic usage. Postmortem examination revealed no anatomic cause for her death. Her

We examined the effects of acute and/or chronic hypokalemia on responses to 30 min of hypoxia and recovery in the isolated, perfused heart model. We found that both acute hypokalemia and chronic hypokalemia impaired contractility [expressed as maximum slope of pressure increase over time (dP/dt):

To investigate whether chronic hypokalemia increases the occurrence of dysrhythmias during anesthesia, the authors recorded the intraoperative electrocardiograms of normokalemic (K+ = 5.0 -3.5 mEq/l; N = 88) and chronically hypokalemic patients (K+ = 3.4 - 2.6 mEq/l; N = 62). In each patient, serum

We investigated the hypothesis that hypokalemia might induce renal injury via a mechanism that involves subtle renal injury and alterations in local vasoactive mediators that would favor sodium retention. To test this hypothesis, we conducted studies in rats with diet-induced K+ deficiency. We also

We present the management of a 15-year-old girl with acute myeloid leukemia who presented with massive hyperleukocytosis and neurological deficit due to intracerebral hemorrhage. Surgical intervention was considered but ultimately not undertaken because of the presence of massive hyperleukocytosis,

A case of maternal pulmonary edema occurring in a patient in the 32nd week of gestation is presented. This was our first case of pulmonary edema seen during a period of five years' usage of isoxsuprine in the treatment of premature labor. The patient presented was 28 years old, gravida 2, para 1,

Oral ingestion of baking soda (sodium bicarbonate) has been used for decades as a home remedy for acid indigestion. Excessive bicarbonate ingestion places patients at risk for a variety of metabolic derangements including metabolic alkalosis, hypokalemia, hypernatremia, and even hypoxia. The

A 59 year-old woman with subarachnoid hemorrhage underwent emergency neck clipping of cerebral aneurysm. Her preoperative examination showed atrial fibrillation, pulmonary edema and hypokalemia. Ventricular fibrillation developed immediately after clipping of the aneurysm and recurred 7 times

Disturbance in acid-base balance is commonly observed in patients with heart failure. The most common disturbance is metabolic alkalosis combined with hypokalemia, as a result of the excessive use of loop diuretics. Occasionary, hypoxia due to pulmonary edema stimulates ventilation, resulting in

BACKGROUND Near-drowning victims in saltwater are expected to have multiple electrolytes imbalance that affected treatment outcome. There are limited data about these parameters in Thailand to guide the treatment plan. OBJECTIVE To study the characteristic of electrolytes imbalance in saltwater

Electrolytic concentrations in plasma and electrocardiographic parameters in dogs have been studied by means of lineal and canonical correlations, after the animals have been submitted to 7% oxygen in nitrogen for three hours. At the end of hypoxia there appeared hypokalemia, increased T wave
