Regional Haemodynamic Changes in Radial Artery Assessment With Continuous Pulsed-wave Doppler Ultrasound

6. marts 2020 opdateret af: Wen-fei Tan, China Medical University, China

Regional Haemodynamic Changes in Radial Artery Assessment With Continuous Pulsed-wave Doppler Ultrasound in Patients Undergoing Video-assisted Thoracic Surgery With Different Kinds of Anaesthesia Management

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.

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Andet: Group control
In the control group, local anaesthesia at the incision was induced by 0.5% ropivacaine by the surgeon just before the surgery.
Medicin: 0.5% ropivacaine local anaesthesia
local anaesthesia at the incision was induced by 0.5% ropivacaine by the surgeon just before the surgery.
Eksperimentel: 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.
Medicin: 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
Eksperimentel: 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
Medicin: 0.25% ropivacaine epidural block
A 4-5 ml bolus of 0.25% ropivacaine was administered 1 h after the initiation of TEB.
