I-Visor ye-Prehospital Stroke Ukuxilongwa

Ukushaywa unhlangothi kubhekisa esimweni lapho ukulahleka okungazelelwe kokusebenza kobuchopho ngenxa yokufa kweseli ngenxa yokugeleza kwegazi okungalungile noma okuphazamisekile ngaphakathi kobuchopho. Izimpawu zokushaywa unhlangothi zibandakanya ubuthakathaka obungazelelwe, ukungakwazi ukunyakaza noma ukuzizwa ngakolunye uhlangothi lomzimba okungukuthi, ukukhubazeka, izinkinga zokuqonda noma ukukhuluma, isiyezi, ukungaboni kahle, ikhanda elibuhlungu nokulahlekelwa ukwazi. Imivimbo ihlukaniswa njenge: -

• Kungaba yischemic, ngenxa yokuntuleka kokugeleza kwegazi
• I-hemorrhagic, ebangelwa ukopha okungalawuleki ebuchosheni okubangela cishe amaphesenti angama-40 okufa kwesifo sohlangothi.

Ukuxilongwa komtholampilo kwesifo sohlangothi kungenziwa kusetshenziswa umlando wesiguli nokuhlolwa komzimba, izivivinyo zokuxilonga njenge-glucose yegazi, ukusuthiswa komoya-mpilo, isikhathi se-prothrombin, ne-electrocardiography, namasu ahlukahlukene we-neuroimaging afana ne-Computed Tomography (CT) noma i-Magnetic Resonance Imaging (MRI). 

Kodwa namhlanje, amadivayisi amaningi amasha futhi athuthukisiwe okuxilonga isifo sohlangothi njenge-visorhage scanning visor, athuthukisiwe ukuze kusheshiswe ukuxilongwa kwesifo sohlangothi, okubalulekile ngoba ukuhlonza nokwelashwa kwesifo sohlangothi kubalulekile ekuthuthukiseni imiphumela yomtholampilo kanye nokuqinisekisa ukuthi iziguli zinikezwa usizo olubalulekile lwezokwelapha. Kunesidingo esibucayi, esibonakala kakhulu esingagcwaliseki sokwenza okusebenzayo, okunembile kokushaywa unhlangothi ngaphambi kwesibhedlela kuma-ambulensi nasemakamelweni okuphuthumayo, ukuhlukanisa phakathi kwezinhlobo ezahlukene zesifo sohlangothi.

Le Visor yaseCerebrotech, eyenziwe yiCerebrotech Medical Systems yasePleasanton, eCalifornia, ukuthi odokotela noma abezimo eziphuthumayo abangayibeka ezigulini ezisolwa ngokuba nesifo sohlangothi kukhombise ukunemba okungama-92% uma kuqhathaniswa nemiphumela yokuxilonga evela ekuhlolweni okujwayelekile okwakungu-40-89% kuphela . Ihlola izimo ezinzima zalesi simo futhi yenze lula isinqumo sayo sokuthi zizithathaphi iziguli kuqala. Iziguli ezinesikhala semikhumbi emikhulu zingadluliselwa esikhungweni se-Comprehensive Stroke Centre esinamandla we-endovascular. Ukudluliswa phakathi kwezibhedlela kuthatha isikhathi esiningi. Uma singanikeza imininingwane kubasebenzi bezimo eziphuthumayo abasensimini ukuthi lokhu kungumkhumbi omkhulu, lokhu kuzosiza ekuhloleni ukuthi yisiphi isibhedlela okufanele baye kuso.

ICerebrotech Visor okulindeleke ukuthi ibe yinto emisha ephezulu ngonyaka we-2019, isebenza ngokuthumela amaza omsakazo onamandla aphansi ebuchosheni futhi ibone imvelo yayo ngemuva kokudlula engxenyeni engakwesobunxele nangakwesokudla, ngaleyo ndlela ihlinzeke ukuxilongwa ngemizuzwana. Ukuvama kwamagagasi kuyashintsha lapho edlula oketshezini olusebuchosheni. Ukushaywa unhlangothi okungathi sína kungadala ushintsho kulolu ketshezi olukhombisa ukushaywa unhlangothi noma ukopha ebuchosheni, okuholela ekutheni kube ne-asymmetry kumagagasi atholwe yi-visor. Lapho i-asymmetry iba nkulu, isifo sohlangothi siba sibi ngokwengeziwe. Le ndlela ibizwa ngokuthi yi-volumetric impedance phase shift spectroscopy (VIPS).

Inqubo ngayinye ithatha cishe imizuzwana engama-30 ngesiguli ngasinye lapho kuthathwa khona ukufundwa okuthathu bese kulinganiswa. Idivayisi ye-VIPS idinga ukuqeqeshwa okuncane kakhulu ukusebenza uma kuqhathaniswa nalokho okudingekayo ukuze kufundwe amakhono ajwayelekile okuhlolwa okuphuthumayo futhi ukuba lula kwayo kunciphisa ubungozi bephutha lomuntu ekuhloleni. 

Ezinyathelweni zabo ezilandelayo, abacwaningi benza ucwaningo lwe-VITAL 2.0 ukuthola ukuthi ngabe idivayisi ye-VIPS ingasebenzisa yini ama-algorithms okufunda okuyinkimbinkimbi ukuze "ifundise" le divayisi ukuze ihlukanise ngokuzimela phakathi kohlangothi oluncane nolunamandla, ngaphandle kokufaka kwe-neurologist.

Idivayisi ye-VIPS isetshenziselwa ukuthola unhlangothi omkhulu ekusetshenzisweni kwe-electrocardiography (ECG) ukuthola ngokuqinisekile ukutholwa kwe-myocardial infarction. Ingasetshenziswa kabanzi ngabasebenzi bezimo eziphuthumayo njenge-defibrillator esetshenziselwa ukuhlola ukuthi isiguli sihlaselwe yinhliziyo yini.
