About this study
Official title: A Two-Center Randomized Controlled Trial
The primary aim of this study was to compare the postoperative analgesic efficacy of thoracic paravertebral block with erector spinae plane block, which we use in thoracotomy surgeries. Secondary aims were to compare these groups in terms of Riker Agitation-Sedation Scale (RASS) scores, postoperative complications, postoperative opioid consumption, and patient satisfaction.
- Conditions
- Paravertebral Block
- Being tested
- Erector Spinae Plane (ESP) block admistring, Thoracic Paravertebral Block administring
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Erector Spinae Plane (ESP) block admistringProcedure or surgery
In the ESPB group, the probe was placed longitudinally at the level of the T5 transverse process, 2-3 cm lateral from the midline. The muscles were visualized superior to the transverse process ; then, the needle was inserted in the craniocaudal direction using the in-plane technique. A dose of 2 mL normal saline were injected into the two layers of the interfacial area under the erector spinae muscle, and the proper injection site was confirmed. After visualizing the linear spread of saline in the fascial plane, 20 mL of 0.25% bupivacaine was injected there for the block.
Thoracic Paravertebral Block administringProcedure or surgery
In the TPVB group, the probe was placed 2-3 cm laterally and vertically of the T5 spinous process. Once the transverse process, corresponding paravertebral space, internal intercostal membrane, and pleura was identified , the needle was inserted in the lateromedial direction using the in-plane technique. After confirmation of pleural displacement with 2 mL saline, 20 mL of 0.25% bupivacaine was administered for the block.
| Study group | Role | What they receive |
|---|---|---|
| Erektor spina plan block | Active comparator | The local anesthetic is injected into the fascial plane between the erector spinae muscle and the transverse processes of the vertebrae. This allows the anesthetic to spread cranially and caudally, affecting multiple spinal nerves Receives: Procedure: Erector Spinae Plane (ESP) block admistring |
| Toracik paravertebral block | Active comparator | The local anesthetic is injected into the paravertebral space, which is bordered by the vertebral bodies, intervertebral discs, parietal pleura, and superior costotransverse ligament. This space contains the spinal nerves, sympathetic chain, and intercostal vessels Receives: Procedure: Thoracic Paravertebral Block administring |
What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric Rating Scale
They will be numbered from 1 to 10. If reporting a score on a scale, please include the unabbreviated scale title, the minimum and maximum values, and whether higher scores mean a better or worse outcome.
Measured: Post-operative 30 minutes, 2 hours, 6 hours, 12 hours, 24 hours
Secondary outcomes (3)
Riker Agitation and Sedation Scale
7 Dangerous Agitation ... If reporting a score on a scale, please include the unabbreviated scale title, the minimum and maximum values, and whether higher scores mean a better or worse outcome.
Measured: Immediately after extubation
Patient satisfaction score:
Patients' satisfaction with the quality of pain management will be assessed on the second postoperative day using the following scale: 1 = very dissatisfied; 2 = quite dissatisfied; 3 = moderate; 4 = quite satisfactory; 5 = very satisfactory.)
Measured: Post-operative 30 minutes
24-hour Tramadol usage:
Amount of Tramadol used per 24 hours
Measured: posoperative 24 hours
