El Perfil Biof\u00edsico<\/strong> combina una evaluaci\u00f3n por ultrasonido con una prueba no estresante (PNE) y est\u00e1 dise\u00f1ado para determinar la salud fetal durante el tercer trimestre. Este examen se lleva a cabo si hay una pregunta sobre la salud y el bienestar del feto, resultante de un examen, los s\u00edntomas maternos o del feto, o si el embarazo se considera de alto riesgo. <\/p>\n

\u00bfC\u00f3mo se Realiza un PBF?<\/strong><\/h3>\n

El PBF consta de dos partes: una Prueba No Estresante (PNE) y una evaluaci\u00f3n por ultrasonido. La PNE consiste en colocar un cintur\u00f3n en el abdomen de la madre para medir el ritmo card\u00edaco fetal y otro cintur\u00f3n para medir las contracciones. El movimiento, el ritmo card\u00edaco y la \u00abreactividad\u00bb del ritmo card\u00edaco al movimiento se miden durante 20 a 30 minutos.
\nSi el beb\u00e9 no se mueve durante un tiempo durante la prueba, no significa que haya un problema; el beb\u00e9 puede estar dormido.
\nUna enfermera puede usar un peque\u00f1o \u00abzumbador\u00bb para despertar al beb\u00e9 para el resto de la prueba. La parte de la prueba de ultrasonido es como cualquier otro ultrasonido obst\u00e9trico realizado durante el embarazo y la realiza un t\u00e9cnico de ultrasonido cualificado que suele ser supervisado por un perinat\u00f3logo.
\nEl ultrasonido puede durar hasta una hora, y el t\u00e9cnico observar\u00e1 una variedad de signos que son importantes para medir la salud de su beb\u00e9. <\/p>\n

\u00bfQu\u00e9 Busca el PBF?<\/strong><\/h3>\n

Generalmente, se estudian y \u00abpunt\u00faan\u00bb cinco atributos fetales espec\u00edficos durante el PBF:<\/strong><\/p>\n\n\n\n\n\n\n\n\n

Tono Muscular<\/td>\n1 o m\u00e1s episodios de extensi\u00f3n\/flexi\u00f3n activa de extremidades, etc. (es decir, abrir y cerrar una mano).<\/td>\nExtensi\u00f3n\/flexi\u00f3n lenta de extremidades, una mano fetal parcialmente abierta, etc.<\/td>\n<\/tr>\n
Ritmo Card\u00edaco<\/td>\n2 o m\u00e1s episodios de aceleraci\u00f3n del ritmo card\u00edaco reactiva en 20 min<\/td>\n1 o m\u00e1s episodios de aceleraci\u00f3n del ritmo card\u00edaco no reactiva<\/td>\n<\/tr>\n
L\u00edquido Amni\u00f3tico<\/td>\n1 o m\u00e1s bolsas de l\u00edquido adecuadas<\/td>\nNo hay bolsas o hay bolsas de l\u00edquido inadecuadas<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

La puntuaci\u00f3n total le ayudar\u00e1 a decidir la salud general y el bienestar de su beb\u00e9 y ayudar\u00e1 a su m\u00e9dico o partera a determinar si su beb\u00e9 debe nacer antes de lo previsto.<\/p>\n

\u00bfCu\u00e1les son los Riesgos y Efectos Secundarios para la Madre o el Beb\u00e9?<\/strong><\/h3>\n

El PBF es una prueba no invasiva que no supone riesgos ni efectos secundarios para la madre o el beb\u00e9, aunque debe tenerse en cuenta cierta preocupaci\u00f3n que se ha planteado en los ultrasonidos que se realizan durante per\u00edodos prolongados de tiempo.<\/p>\n

\u00bfCu\u00e1ndo se Realiza un PBF?<\/strong><\/h3>\n

Un PBF se realiza generalmente despu\u00e9s de las 32 semanas de gestaci\u00f3n.<\/p>\n
