American designers have created a unique diagnostic device that looks like a visor: such a simple device has the ability to determine the presence of a stroke in half a minute. The accuracy of the diagnosis is estimated by specialists at 92%.
Doctors have already noticed significant differences in the functionality of the new device, compared to conventional diagnostic methods. Previously, the accuracy of the diagnosis was approximately 40-89%.
A stroke is a critical condition that in many cases leads to the death of patients. It is very important to promptly determine the presence of such a disorder in order to begin treatment - the sooner the better.
The first clinical tests of the device were conducted with the involvement of 248 participants: 41 of them had already suffered an acute cerebrovascular accident, 128 patients had some signs of a stroke at the time of diagnosis, and 79 participants did not suffer from any similar pathologies and were completely healthy. The following results were obtained during the experiment: the device was able to detect a stroke in 93% of patients, and healthy participants were identified in 92% of cases.
Experts explained: the unique device uses radio waves to monitor the movement of fluids in the brain. If there is a fact of a stroke, the device determines the vascular obstruction. The more significant such a violation, the more serious the tissue damage can be.
Diagnosing a stroke as early as possible is a task that doctors have been facing for a long time. If the pathological condition is detected within 24 hours after the disorder, the patient can undergo surgery, which significantly improves the prognosis for the patient's health. However, every 60 minutes from the moment of the stroke reduces the chance of a positive outcome by about 20%. The researchers knew about this problem and set themselves the task of providing medical workers with a device that could detect cerebrovascular accidents as early and as quickly as possible.
As the scientists speculate, the unique "visor" will be able to transform the mechanism for distributing incoming patients to clinical departments. After all, in the case of a diagnosed stroke, doctors will be able to immediately send the patient for the necessary treatment procedures, bypassing the lengthy diagnostic confirmation stage.
"Transportation from department to department, or from clinic to clinic takes a lot of precious time," notes one of the authors of the development, Raymond Turner, "if the doctor receives the final diagnosis immediately, he will be able to freely begin the treatment process, which will certainly save many lives."
The first tests of the diagnostic “visor” device are described in the pages of the periodical Journal of Neurointerventional Surgery.
