I aquest prec\u00eds moment \u00e9s el que queda plasmat a la imatge de resson\u00e0ncia magn\u00e8tica<\/strong> de dalt: una p\u00e8rdua de connexi\u00f3 entre l’escor\u00e7a cerebral (en vermell) i la part subcortical i el tronc cerebral (en blau) que apaga els llums de la consci\u00e8ncia.<\/p>\n\n\n\n

La imatge forma part d’un estudi <\/a>desenvolupat a l’Hospital del Mar per investigadors i investigadores de l’Institut Hospital del Mar d\u2019Investigacions M\u00e8diques (IMIM)<\/a>, el Servei d’Anestesiologia i la Unitat de Resson\u00e0ncia Magn\u00e8tica del Servei de Radiologia, on han aconseguit determinar el moment exacte de la p\u00e8rdua de consci\u00e8ncia despr\u00e9s de l’administraci\u00f3 de propofol, un f\u00e0rmac anest\u00e8sic. <\/strong><\/p>\n\n\n\n

Aix\u00ed, gr\u00e0cies al monitoreig de l’activitat cerebral<\/strong> dels voluntaris <\/a>amb un electroencefalograma i imatges de resson\u00e0ncia magn\u00e8tica<\/a> han pogut veure i determinar el moment exacte on es produeix la desincronitzaci\u00f3 entre l’activitat del c\u00f3rtex i el subc\u00f3rtex cerebral.<\/p>\n\n\n\n

Amb aquesta troballa, comenten els autors, es podria calibrar millor l’estat del pacient i s’evitaria amb m\u00e9s facilitat la sobredosificaci\u00f3 de f\u00e0rmacs anest\u00e8sics<\/strong> i els seus possibles efectes secundaris<\/a> post-operatoris.<\/p>\n\n\n\n
