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.
Patients who will undergo thoracotomy and are between the ages of 18-65
have American Society of Anesthesiologists (ASA) risk classification I-II will be included in the study.
Patients who did not agree to participate in the study,
had an infection in the application area,
had coagulopathy,
were morbidly obese (Body mass index (BMI)>35),
Parallel
Erector Spinae Plane (ESP) block admistring
Procedure/SurgeryIn 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 administring
Procedure/SurgeryIn 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.
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.
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.
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.)
