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.

Detailed description

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. The patients in this trial were visited during the entire operation and just before leaving the post-anaesthesia care unit. Velocity-associated data related to pulsed-wave Doppler ultrasound and the consumption of phenylephrine were collected.

Conditions

Interventions

TypeNameDescription
DRUG0.5% ropivacaine paravertebral blockThe 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
DRUG0.25% ropivacaine epidural blockA 4-5 ml bolus of 0.25% ropivacaine was administered 1 h after the initiation of TEB.
DRUG0.5% ropivacaine local anaesthesialocal anaesthesia at the incision was induced by 0.5% ropivacaine by the surgeon just before the surgery.
