Prevention of recurrent eclamptic seizures requires the administration of magnesium sulfate. However, to our knowledge, there are no reports of cases in which the ionized magnesium concentration has been monitored during magnesium sulfate administration to prevent eclampsia. We describe a case in which monitoring of ionized magnesium permitted the use of magnesium sulfate to prevent a third eclamptic seizure. A 31-year-old primigravida with severe preeclampsia and eclampsia underwent emergency cesarean delivery. The patient had a recurrence of seizures intraoperatively. Postoperatively, she was managed with continuous magnesium sulfate infusion under ionized magnesium monitoring at the bedside using a blood gas analyzer in the intensive care unit. This approach might have helped prevent further seizures and complications associated with the administration of magnesium sulfate, such as hypermagnesemia. This case indicates that in the use of magnesium sulfate for patients with preeclampsia, ionized magnesium measurement was used for the rapid determination of magnesium levels.

Electroconvulsive Therapy01:30

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Antiepileptic Drugs: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Arteries of the Lower Limbs

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Antiepileptic Drugs: Sodium Channel Blockers01:08

Antiepileptic Drugs: Sodium Channel Blockers

Antiepileptic drugs are specialized medications that prevent seizures in individuals diagnosed with epilepsy. These drugs primarily function by blocking the movement of sodium ions through channels in the neuronal membrane, inhibiting the repetitive firing of action potentials often associated with seizures.
Sodium channel blockers modulate ion channels, particularly voltage-gated sodium channels. They block only sodium ion movement.
Among the most commonly prescribed antiepileptic drugs are...
