Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 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.;Secondary Objective: 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.;Primary end point(s): MDA plasma levels at 12 hours after reperfusion;Timepoint(s) of evaluation of this end point: 12 hours after reperfusion. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): MDA plasma levels 24 hours after reperfusion. SOD serum levels 12 hours after reperfusion. SOD serum levels 24 hours after reperfusion. Partial surface or total flap fat necrosis, according to clinical criteria based on the measurement area to total necrosis of the flap. This standard will bemeasured by photography and paper overlay grid.;Timepoint(s) of evaluation of this end point: 12 and 24 hours after reperfusion. 7,14,30 days after reperfusion. | — |
