其他:Group control
In the control group, local anaesthesia at the incision was induced by 0.5% ropivacaine by the surgeon just before the surgery.

实验性的:Paravertebral Block Group
In Group Paravertebral Block, patients received standardized general anaesthesia supplemented by paravertebral Block.
The USG approach for TPVB was used with the patient in the lateral position at the T4-T6 level according to the incision protocol in our centre.
|
The investigators designed a study to assess whether there were any blood flow indexes change during induction with doppler ultrasonography after 0.5% ropivacaine paravertebral block
|
|
实验性的:Epidural Block Group
The investigators designed a study to assess whether there were any blood flow indexes change during induction with doppler ultrasonography ;general anesthesia combined with epidural block
|
A 4-5 ml bolus of 0.25% ropivacaine was administered 1 h after the initiation of TEB.
