Abstract EN
Single injections in the anterior region of the thoracic paravertebral space (TPVS) have been reported to generate a multisegmental longitudinal spreading pattern more frequently than those in the posterior region of the TPVS.
In this trial, we examined the hypothesis that a continuous thoracic paravertebral block (TPVB) administered through a catheter inserted into the anterior region of the TPVS allows a wider sensory block dispersion.
Fifty consecutive patients undergoing video-assisted thoracic surgery were enrolled.
Before the surgery, an infusion catheter was inserted into the TPVS through a needle placed adjacent to either the parietal pleura (group A) or internal intercostal membrane (group P) using an ultrasound-guided intercostal transverse approach according to a randomized allocation schedule.
A chest radiograph was obtained postoperatively after injection of 10 mL of radiopaque dye through the catheter.
Thereafter, 20 mL of 0.375% levobupivacaine was injected via the catheter, followed by commencement of continuous TPVB with 0.25% levobupivacaine at 8 mL/h.
The primary outcome was the number of blocked dermatomes at 24 h after surgery.
The secondary outcomes included radiopaque dye spreading patterns, the number of segments reached by the radiopaque dye, the number of blocked dermatomes at 2 h after surgery, and pain scores.
The median (interquartile range [range]) number of blocked dermatomes 24 h after surgery was 3 (2.75–4 [1–6]) in group A (n = 22) and 2 (1.5–3 [0–7]) in group P (n = 25; p = 0.037).
No significant differences in the other outcomes were found between the groups.
In conclusion, a continuous TPVB administered using a catheter supposedly inserted into the anterior region of the TPVS allows a wider sensory block dispersion than a catheter inserted into the posterior region of the TPVS.
This trial is registered with the UMIN Clinical Trials Registry (UMIN000018578).
