Acquired torsade de pointes ventricular tachycardia (TdP) is a rare but serious life-threatening arrhythmia caused by an array of cardiac and non-cardiac drugs. It is often refractory to pharmacological therapy and may result in death or require frequent defibrillations. In our case study a young
We report an emergency medical services (EMS) case of self-limited torsade de pointes after administration of droperidol for nausea and vomiting in a patient with potential predisposing factors for the development of prolonged QT interval. Despite the reported association with torsade de pointes,
A 75-year-old man presented to the emergency department (ED) for syncope and was found to have intermittent runs of torsades de pointes (TdP). The patient had a medical history significant for disseminated coccidiomycosis and was on prophylactic fluconazole. Forty-eight hours prior to presentation,
Postoperative nausea and vomiting (PONV) are significant issues in surgical patients, and additional treatment options are needed. Dopaminergic antiemetics have been popular for their efficacy, but their use has been limited by safety concerns, especially the potential for torsade de A case of sultopride poisoning (ingested dose 16 g) in a 35-year-old, 65 Kg man is described. On admission myoclonus, mydriasis, vomiting and cardio-respiratory arrest were observed. Torsades de pointes were treated with potassium chloride infusion and pace maker stimulation. Plasma sultopride
An 83-year-old female, who had a history of anterior myocardial infarction, was treated for Alzheimer's disease with donepezil. She suffered from repeated diarrhea and vomiting, and experienced syncope. She was admitted to our hospital and was diagnosed with acute colitis and syncope. On admission,
An 80-year-old woman with Alzheimer's dementia presented with diarrhoea, vomiting and worsening confusion following an increase in donepezil dose from 5 to 10 mg. The ECG revealed prolongation of QTc interval. Soon after admission, she became unresponsive with polymorphic ventricular tachycardia
BACKGROUND
The 5-hydroxytryptamine type 3 antagonists, or setrons (eg, ondansetron), are commonly used for nausea and vomiting in the hospital setting. In 2001, droperidol was given a black box warning because it was found to prolong the QT interval and induce arrhythmias. The setrons share with
We report a 9-year-old boy with occipital lobe epilepsy who showed a prolonged QTc on the ictal electrocardiogram (ECG). He complained of sudden onset of blindness accompanied with vomiting and headache. Since ECG revealed a prolonged QTc, he was transferred to our pediatric emergency center.
OBJECTIVE
To compare the effects of droperidol and ondansetron on electrocardiographic indices of myocardial repolarization in children.
OBJECTIVE
To refine understanding of the torsadogenic risk to children exposed to anti-emetic prophylaxis in the perioperative period.
BACKGROUND
QT interval
In December 2001, the United States Food and Drug Administration (FDA) added a "black box" warning to the labeling for droperidol stating that all doses, even those typically used for postoperative nausea and vomiting, were potentially associated with malignant ventricular dysrhythmias, including
(1) Betablockers such as atenolol are the first-line symptomatic treatment for stable angina. Calcium channel blockers such as verapamil and amlodipine are second-line alternatives; (2) Ranolazine is now authorized for symptomatic adjuvant treatment of angina in patients who are poorly controlled by
Prochlorperazine, a drug for the symptomatic control of nausea, vomiting and psychiatric disorders, can induce prolonged QT, torsades de pointes and sudden death. We studied the effects of prochlorperazine on human ether-a-go-go-related gene (HERG) channels expressed in Xenopus oocytes and also in
Acodazole (NSC 305884) is a synthetic imidazoquinoline which has antimicrobial as well as antineoplastic properties. A Phase I trial of acodazole administered as a 1-h i.v. infusion once weekly X 4 was conducted. Mild to moderate nausea and vomiting and moderate burning and erythema at the infusion
Electrolytes are essential for basic life functioning such as maintaining electrical neutrality in the cells, generation, and conduction of action potentials in the nerves and muscles. Sodium, potassium, and chloride are the significant electrolytes along with magnesium, calcium, phosphate, and
