RESUMEN
Tipo de estudio retrospectivo, longitudinal y analítico.

Objetivos:

•Evaluar el comportamiento de la tensión arterial materna, durante la operación cesárea de pacientes preeclámpticas que reciben anestesia epidural con lidocaína al 2% con epinefrina al 1200,000.•Evaluar si la utilización de lidocaína con epinefrina afecta la hemodinamia materna, hasta contraindicarla en la anestesia epidural de la paciente preeclámptica. Hipótesis La epinefrina en la anestesia epidural, produce crisis hipertensiva en las pacientes preeclámpticas.

Resultados:

Una vez instalada la anestesia epidural, las tensiones arteriales mostraron un descenso gradual, más acentuado al minuto 35 posterior a la administración de la dosis total de lidocaína con epinefrina, que corresponden a la máxima extensión metamérica y a la mayor profundidad obtenida con el bloqueo epidural, así como a la descompresión abdominal y a la hemorragia quirúrgica tras la extracción del producto; conforme aumentó la cantidad perfundida de soluciones intravenosas, la tensión arterial inició un ascenso paulatino sin haber requerido soporte vasopresor. Ninguna paciente respondió con crisis hipertensiva a la administración de lidocaína con epinefrina.

Conclusiones:

Se concluye que en cesárea de preeclampticas previamente tratadas, la anestesia epidural fraccionando lidocaína con epinefrina no produce hipertensión arterial ni colapso vascular materno, se pueden predecir y por lo tanto evitar los descensos tensionales
ABSTRACT
Type of study retrospective, longitudinal and analytic study

Objectives:

•To evaluate the behavior of the maternal arterial tension, during the Caesarean operation of preeclamptic patients that received epidural anesthesia with lidocain 2% with epinephrin 1200,000.•To evaluate if the lidocain used with epinephrin affects the maternal hemodynamic, that it would lead to contraindicate it in the epidural anesthesia of the preeclamptic patient.

Hypothesis:

The enunciated hypothesis was The epinephrin in the epidural anesthesia, produces hipertensive crisis in the preeclamptic patients.

Results:

Once the epidural anesthesia is administered , the arterial tensions showed a gradual decrease, accentuated 35 minute later to the administration of the total dose of lidocain with epinephrin that corresponds to the maximum metametric extension and the biggest depth obtained with the epidural block. Also to abdominal decompression and the surgical hemorrhage after the extraction of the product. As the quantity of intravenous solutions are prefused increases, the arterial tension increases it began a gradual increase without having required vasopressor support. No patient responded with hipertensive crisis to the lidocain administration with epinephrin.

Conclusions:

We conclude that in Caesarean operation of previously treated preeclamptic patients, the epidural anesthesia fractioning lidocain with epinephrin doesn't produce hypertension nor maternal vascular collapse, they can be predicted and therefore be able to avoid a decrease in arterial tension.
