Adem\u00e1s de los s\u00edntomas anteriores, la intoxicaci\u00f3n moderada muestra temblor muscular y aumento de la presi\u00f3n arterial. La intoxicaci\u00f3n grave puede aparecer edema pulmonar, coma, edema cerebral, actividad de la colinesterasa en sangre total en 30% o menos, y en casos graves, hay par\u00e1lisis de los m\u00fasculos respiratorios, insuficiencia respiratoria e incluso la muerte.  Adem\u00e1s, la contaminaci\u00f3n cut\u00e1nea puede causar ardor, enrojecimiento, erupci\u00f3n cut\u00e1nea; la contaminaci\u00f3n conjuntival puede causar sensaci\u00f3n de ardor, lagrimeo, estrechamiento de la pupila, etc.<\/span><\/p>\n<p class=\"MsoNormal\" style=\"text-indent: 21.0000pt; mso-char-indent-count: 2.0000; text-autospace: ideograph-numeric; mso-pagination: none; text-align: justify; text-justify: inter-ideograph; line-height: 125%;\" align=\"justify\"><span style=\"mso-spacerun: 'yes'; font-family: \u5b8b\u4f53; font-size: 10.5000pt; mso-font-kerning: 1.0000pt;\">La sospecha de intoxicaci\u00f3n por insecticidas carbamatos debe tratarse con prontitud, y el diagn\u00f3stico definitivo puede hacerse mediante una historia clara de exposici\u00f3n, s\u00edntomas, signos y s\u00edntomas, combinados con los resultados de las pruebas de colinesterasa y toxicol\u00f3gicas.
