No results posted yet for this study

Summary

The objective of the trial was to evaluate velocity-associated parameters of pulsed-wave Doppler ultrasound at induction, discharge from the post-anaesthesia care unit and during inspiratory cough in addition to the consumption of phenylephrine during the operation in patients undergoing video-assisted thoracic surgery with three types of anaesthesia management.

Conditions

Interventions

DRUG

0.5% ropivacaine paravertebral block

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

DRUG

0.25% ropivacaine epidural block

A 4-5 ml bolus of 0.25% ropivacaine was administered 1 h after the initiation of TEB.

DRUG

0.5% ropivacaine local anaesthesia

local anaesthesia at the incision was induced by 0.5% ropivacaine by the surgeon just before the surgery.
