A 64-year-old man ingested 4500 mg of maprotiline hydrochloride. He developed major motor myoclonic seizures, first-degree AV block, intraventricular conduction delay, hypotension, and urinary retention. Myoclonic seizures have not been previously reported with maprotiline toxicity.
A 31-year-old man ingested 400 mg of citalopram (Celexa) after an argument with his parents and girlfriend 13 h before presentation. Paramedics witnessed the patient having a generalized clonic seizure. The electrocardiogram (EKG) revealed a wide QRS complex, prolongation of the QTc interval, and
Isolated hearts from two strains of rats bred for sensitivity or resistance to amygdala kindling that also exhibit, in vivo, differential sensitivity to the cardiotoxicity of cocaine were studied. The goal was to determine if the differential cardiotoxic sensitivity was due, at least in part, to
Lacosamide is a third-generation antiepileptic drug. Its likely mechanism of action is via neuronal sodium channel blockade, via a unique manner compared with other antiepileptic drugs that block sodium channels. A paucity of information exists regarding lacosamide overdosage. OBJECTIVE
Despite numerous studies examining the effect of lipid emulsion on bupivacaine-induced cardiac toxicity, few studies have examined its effect on central nervous system (CNS) toxicity of local anesthetics. We investigated the effect of lipid emulsion on the CNS and cardiac toxicity of
Regional anesthesia techniques use local anesthetics to provide sensory and motor block for surgical intervention. Intravascular absorption of the local anesthetics may induce toxic effects, such as seizure activity or cardiac depression, leading to cardiac arrest. Standard, prolonged resuscitation
BACKGROUND
This is a case of a citalopram and olanzapine overdose causing seizures and severe cardiotoxicity.
METHODS
A 21-year-old man presented unresponsive, with seizures, to an Emergency Department. The patient's initial electrocardiogram demonstrated a widened QRS of 160 ms and a normal QT/QTc
Lamotrigine is a sodium and calcium channel blocker, used to treat seizures in people. Dogs metabolize Lamotrigine to a cardiotoxic metabolite that causes severe, often fatal ventricular arrhythmias. This report documents the successful treatment of refractory Lamotrigine cardiotoxicity in a dog,
Accidental intravascular administration of bupivacaine during performance of a brachial block precipitated convulsions followed by asystole. The patient was rapidly resuscitated using cardiopulmonary resuscitation, supplemented by 150 mL of 20% lipid emulsion. Nonetheless, cardiac toxicity
We report a case of grand mal convulsion due to inadvertent intravascular injection of ropivacaine. An 83-year-old woman was scheduled for upper limb surgery. The interscalene block was performed with neurostimulator and 0.5% ropivacaine 30 ml was injected after careful negative aspiration.
On the basis of case reports and small non-comparative series it has been suggested that thioridazine has greater cardiotoxicity in overdose. Limited evidence also suggests an increased association with sudden death in therapeutic doses. The aim of our study is to examine the clinical and
The effect of acutely elevated serum magnesium on the CNS and cardiac toxicity of bupivacaine was studied. Anesthesia was induced in mongrel dogs with thiopental, 25 mg/kg, and ventilation was controlled. Sedation was maintained with fentanyl (25 micrograms/kg bolus and 5 micrograms.kg-1h-1) and
Suppression of nitric oxide (NO) production alters the toxicity of cocaine and bupivacaine. We undertook this study to determine whether the systemic toxicity of two other local anesthetics that differ in antiarrhythmic activity, plasma clearance, and biotransformation are similarly affected by
Trazodone is a serotonin antagonist and reuptake inhibitor that is widely used for the treatment of depression and insomnia. Fatal overdose is rare and usually occurs when combined with other drugs or alcohol. Only a few lethal cases of pure trazodone overdose have been reported, all attributed to
