Abstract

Se proporciona un aparato de electrolocalizacion para localizar un nervio el cual puede suministrarse anestesia. El aparato incluye un conjunto de aguja que tiene una aguja eléctricamente conductora, un tubo no conductor asegurado por encima de la cánula de aguja y galvanizacion conductora sobre el tubo. Los conductores están conectados con un estimulador que genera impulsos de carga alternativa elevado y bajo con un nivel de corriente bajo constante. Los impulsos de carga elevada generan sacudidas musculares perceptibles inmediatamente después de la insercion de la aguja en el paciente. Las sacudidas musculares que responden a los impulsos de carga elevada llegarán al máximo en magnitud y las sacudidas musculares que responden a los impulsos de carga baja se harán observables a medida que la carga se aproxima al nervio de referencia y no serán capaces de distinguirse de las sacudidas musculares que responden a los impulsos de carga elevada cuando la aguja está en una posicion para la administracion del anestésico.
