To evaluate the effect of lidocaine in the decrease of ischemic-reperfusion injury from breast microsurgical reconstruction, based on the MDA plasma levels at 12 hours after reperfusion. |
Evaluar el efecto de la lidocaína en la reducción del daño tisular producido por la isquemia-reperfusión en la cirugía de reconstrucción mamaria microquirúrgica, mediante la disminución de los niveles plasmáticos de MDA a las 12 horas de la reperfusión. |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate plasma levels of MDA at 24 hours after reperfusion, in patients who received lidocaine, compared with untreated patients. 2. To evaluate SOD serum at 12 and 24 hours after reperfusion, in patients who received lidocaine, compared with untreated patients. 3.To evaluate the percentage of surface flap necrosis in patients who received lidocaine compared with untreated patients trhough clinical assessment in Plastic Surgery medical appoinments at 7, 14 and 30 days after reperfusion. |
1. Evaluar los niveles plasmáticos de MDA a las 24 horas de la reperfusión, en las pacientes a las que se les administre lidocaína, comparando con las pacientes sin tratamiento. 2. Evaluar los niveles séricos de SOD a las 12 y 24 horas de la reperfusión, en las pacientes a las que se les administre lidocaína, comparando con las pacientes sin tratamiento. 3. Evaluar el porcentaje de superficie de necrosis del colgajo en las pacientes a las que se les administre lidocaína comparando con las pacientes sin tratamiento, mediante la evaluación clínica en consulta de Cirugía Plástica a los 7, 14 y 30 días de la reperfusión. |
