Riley Hospital for Children at IU Health flu-related visitor restrictions have been lifted. However, because babies, especially those who are ill or premature, are at higher risk of serious complications if they get the flu, visitation restrictions are still in place for all Neonatal Intensive Care Units (NICUs) until further notice.
Vagal nerve stimulator (VNS) therapy is used to control seizures by sending electrical impulses to the brain from the vagus nerve in the neck. This treatment controls the type of brain activity that often leads to seizures.
The vagus nerve is a cranial nerve that controls parasympathetic functions, sending signals to every organ in the body. The vagus nerve also collects information from all parts of the body. Overstimulation of the vagus nerve is the most common cause of fainting.
VNS therapy is used in children with epilepsy or seizures that are difficult to treat or do not respond to oral anticonvulsant medicines.
VNS therapy is used with medicines and is not a replacement for them. VNS therapy does not require brain surgery. A simple two- to four-hour procedure is required to implant a pacemaker-like device in the chest that is connected to the vagus nerve with a flexible wire called a lead.
Once implanted, the vagal nerve stimulator generates an electronic pulse to the vagus nerve at regular intervals every few minutes. The nerve transmits this signal to the brain. Older children who feel a seizure coming can trigger the electrical signal, which can often stop the seizure.
VNS therapy, in combination with medicines, reduces the number of seizures and their intensity. The treatment also shortens seizure recovery time.
More than 75,000 people use VNS therapy to treat epilepsy and seizures. The U.S. Food and Drug Administration approved the treatment in 1997. Focal seizures (which affect only one part or one side of the brain) respond well to vagal nerve stimulation, and a growing body of scientific literature shows that generalized seizures (which affect the whole brain or a large part of it and can affect consciousness) also respond to VNS therapy.
If your child shows signs of epilepsy or seizures that do not respond to other treatments, his or her neurologist may recommend a vagal nerve stimulator. You and your child will meet with a neurosurgeon before the procedure to discuss the procedure and answer your questions.
You can expect the following on the day of your child’s stimulator implantation procedure:
You can expect the following two weeks after the procedure:
The risk of a vagal nerve stimulator procedure includes a small chance of infection at the incision site.
