About this trial

The goal of this clinical trial is to learn if patients remaining different positions for 30min after receiving ultrasound-guided erector spinae plane block influenced the postoperative analgesia. The main questions it aims to answer are:

Does patients maintain prone position or lateral position for 30 min after ESPB provided superior analgesic effect than in the supine position? Is ESPB not inferior to PVB considering postoperative opioid consumption ? Researchers will compare the opioid consumption 24h postoperatively among the patients remaining supine, lateral, prone position after ESPB and PVB to see if patients maintaining lateral or prone position provided excellent postoperative analgesia.

Participants will:

Maintaining supine lateral or prone position for 30 min following ESPB or receiving PVB.

Receiving postoperative NRS and QoR assessment

    Procedure/Surgery

    Patients undergoing Video-assisted Thoracoscopic Surgery were selected for the study, and nerve block was performed before surgery, followed by holding different positions for 30 min, after which the effect of the block was measured.

Trial outcomes

Primary outcomes

1

Postoperative Oxycodone dosage

Cumulative oxycodone dosage 24 hour postoperatively

Time frame
24 hour postoperatively

Secondary outcomes

1

Loss to cold sensation of skin

The sensation to cold was assessed with ice. The area include the anterior chest wall (midclavicular line), lateral chest wall (posterior axillary line), and posterior chest wall (paraspinal zone) by a researcher who was blinded to group allocation.

Time frame
30 minute after block
2

NRS(Numeric Rating Scales) score

Postoperative 1, 3, 6, 12, 24, 48 hour NRS (Numeric Rating Scales) score. Numerical Rating Scale (NRS): This scale is composed of 11 numbers from 0 to 10, with higher numbers increasing the severity of pain.

Time frame
Postoperative 1, 3, 6, 12, 24, 48 hour
3

Adverse reaction

This includes dizziness, nausea, vomiting, etc.

Time frame
24, 48 hour postoperatively
4

QoR-15 score(Quality of Recovery,QoR)

Postoperative QoR-15(Quality of Recovery) score was used to evaluate the quality of early postoperative recovery on postoperative day 1 and 2. . The QoR-15 score(Quality of Recovery,QoR) included 5 dimensions including emotional state, physical comfort, psychological support, physical independence and pain, with a total of 15 items. Each item scored from 0 to 10, with higher scores being better.

Time frame
Day 1 and 2 postoperatively
