A Low-Cost Improvised Nerve Stimulator is Equivalent to High-Cost Muscle Stimulator for Anorectal Malformation Surgery

A low cost color visual stimulator for fMRI.

This low cost visual stimulator was developed for use in small animal imaging. The stimulator uses a single tri-color LED for each eye and can output red, green, or blue light or any combination of the three. When all three LED colors are illuminated at the same time achromatic light is the output. The stimulator is almost entirely implemented in software with only minimal electronics. The LEDs...

Low-cost computer-controlled current stimulator for the student laboratory.

Electrical stimulation of nerve and muscle tissues is frequently used for teaching core concepts in physiology. It is usually expensive to provide every student group in the laboratory with an individual stimulator. This article presents the design and application of a low-cost [about $100 (U.S.)] isolated stimulator that can be controlled by two analog-output channels (e.g., output channels of...

Cardiac Surgery in a Patient with Implanted Vagal Nerve Stimulator

The prevalence of epilepsy worldwide is around 0.5%-2% of the population. Antiepileptic medications are the first line of treatment in most of the cases but approximately 25%-30% epilepsy patients are refractory to the single or combination therapy. The surgical option for temporal lobe epilepsy is temporal lobectomy, which has its inherent risk of neurological deficits after the surgery. Patie...

Nerve Stimulator with High Reliability for Assistance in Regional Anesthesia

Nerve stimulator guided pudendal nerve blocks.

We attribute this to the young age of the patient, prompt treatment, and the rapid resolution of symptoms following institution of therapy. It is possible that older infants and adults exhibit more marked elevations in serum CPK due to their relative increased muscle mass. Also noteworthy, was the self-limited fever and tachycardia following her initial anesthetic. Unexplained fever and tachyca...
