Effect of Epidural Anesthesia on Blood Flow in Arterial Anastomosis of Free Flap

Randomized Trials of Epidural Combined With General Anesthesia Versus General Anesthesia Alone to Evaluate the Changes of Blood Flow in Arterial Anastomosis of Free Flap Using Duplex Ultrasonography

Summary

Comparing the changes of arterial anastomotic blood flow between general anesthesia alone and general anesthesia with epidural anesthesia in patients who undergoing free flap transposition using Duplex ultrasound.

Detailed description

Maintaining adequate blood flow is important on the success of free flap surgery. Epidural anesthesia can influence blood flow during surgery. Therefore, investigators aim to compare the effect of epidural anesthesia combined with general anesthesia and general anesthesia alone on blood flow in arterial anastomosis site of the free flap.

Conditions

• Free Tissue Flaps

Interventions

Type	Name	Description
OTHER	Epidural anesthesia	After anesthesia induction, epidural catheter is inserted into lumbar epidural in epidural with general anesthesia group. A 10 ml of 0.2% ropivacaine should be given in epidural space via a catheter when anastomosis of free flap is finished in epidural with general anesthesia group.
