Bezprzewodowy czujnik radiowy do wykrywania napadów epilepsji i zmian oddychania w jednostce monitorowania - badanie wstępne
A wireless and contactless radio frequency sensor to detect bilateral tonic-clonic seizures and respiratory changes in the epilepsy monitoring unit: a phase 0/1 study
W skrócie
Badacze przetestowali nowe urządzenie, które bez kontaktu z ciałem pacjenta i za pomocą fal radiowych potrafi wykrywać napady epilepsji. Urządzenie skutecznie rozpoznawało napady w badanej grupie i mogło także monitorować zmiany oddychania pacjenta podczas napadów. Wyniki sugerują, że taka technologia mogłaby być używana do bezpiecznego monitorowania pacjentów z epilepsją na oddziałach szpitalnych.
Oryginalny abstract (angielski)
A novel wireless motion-detection device (WMDD) utilizes a low radio frequency (RF) emission/sensing system to isolate a patient's movement with high sensitivity and spatial resolution. The device was evaluated for detecting focal to bilateral tonic-clonic seizures (FBTCS) and respiratory changes. A prospective study of patients ≥18 years old admitted to a tertiary care epilepsy monitoring unit was conducted. Data from the WMDD was compared to video-EEG and respiratory inductive plethysmography (RIP) belts to assess the onset of convulsive seizures and to assess respiratory signals. Eighty-seven consecutive patients were enrolled, including 9 with RIP belts; 11 FBTCS were captured. The WMDD revealed identifiable RF signal changes in all FBTCS at the onset of motor activity. Higher total RF amplitude was seen during FBTCS, compared to non-seizure movements from interictal controls. The WMDD was able to detect respiratory changes that correlated with RIP changes. A contactless device using low-power RF that does not require a line-of-sight may be developed to detect FBTCS.
