About this study
Official title: Comparison of Effectiveness of Erector Spinae Plane Block and Thoracal Paravertebral Block for Postoperative Analgesia After Cardiovascular Surgery: Randomized Study
Pain is a common and serious problem after cardiovascular surgery. It is associated with increased morbidity and mortality, and additional risk factors of cardiac surgery such as sternotomy and cardiopulmonary bypass contribute to this. Patient-controlled analgesia with intravenous opioids is standard in many centers for the management of pain after cardiac surgery. However, intravenous opioids have a higher risk of nausea and vomiting and may delay weaning from mechanical ventilation compared to regional techniques. Elderly patients have a higher risk of opioid-related complications, and regional techniques can help reduce postoperative ventilation time and accelerate postoperative recovery, which will reduce the risk of atelectasis, especially in the elderly population. Thoracic paravertebral block (TPVB) is difficult to apply due to its anatomical proximity to important structures such as the pleura and central neuraxial system, and may cause complications such as pneumothorax and vascular injury. Analgesia management is very important in these patients, since insufficient analgesia may cause pulmonary complications such as atelectasis, pneumonia, and increased oxygen consumption in the postoperative period.
Erector spina plane (ESP) block performed with ultrasound (US) is a new interfacial plane block defined by Forero et al. in 2016. If the ESP block is applied at the T5 level, it provides thoracic analgesia, if it is applied at the T7-9 level, it provides analgesia in the abdominal region.
In this study, it is aimed to compare the effectiveness of US-guided ESP block and TPVB for postoperative analgesia management after cardiovascular surgery. Our primary aim is to compare postoperative pain scores (NRS), and our secondary aim is to evaluate rescue analgesia using, opioid-related side effects (allergic reaction, nausea, vomiting) and complications that may occur due to block (pneumothorax, hematoma).

Thoracic paravertebral block (TPVB) is difficult to apply due to its anatomical proximity to important structures such as the pleura and central neuraxial system, and may cause complications such as pneumothorax and vascular injury. Analgesia management is very important in these patients, since insufficient analgesia may cause pulmonary complications such as atelectasis, pneumonia, and increased oxygen consumption in the postoperative period.
Erector spina plane (ESP) block performed with ultrasound (US) is a new interfacial plane block defined by Forero et al. in 2016. If the ESP block is applied at the T5 level, it provides thoracic analgesia, if it is applied at the T7-9 level, it provides analgesia in the abdominal region. This block is applied by injecting a solution containing local anesthetic into the fascia under the erector spina muscle. Since the application site of the ESP block is far from the pleura and neuraxial tissues, it minimizes the risk of complications due to injury to these structures. Sonoanatomy is easy to visualize on US and the spread of local anesthetic can be seen easily. With the cephalo-caudal spread of the local anesthetic solution, analgesia occurs in several dermatomes. Cadaveric studies have shown that the injection spreads to the ventral and dorsal roots of the spinal nerves and creates sensory blockade in both the anterolateral thorax and the posterior. In the literature, it has been reported that it provides effective analgesia in randomized controlled studies investigating the effectiveness of ESP block for postoperative analgesia management after open heart surgery, breast surgery and ventral hernia repair.
In this study, it is aimed to compare the effectiveness of US-guided ESP block and TPVB for postoperative analgesia management after cardiovascular surgery. Our primary aim is to compare postoperative pain scores (NRS), and our secondary aim is to evaluate rescue analgesia using, opioid-related side effects (allergic reaction, nausea, vomiting) and complications that may occur due to block (pneumothorax, hematoma).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Postoperative managementOther
1 g paracetamol will be administered 3 x 1. If the NRS score is ≥ 4, 1 mg kg-1 iv tramadol will be administrated.
| Study group | Role | What they receive |
|---|---|---|
| Erector spinae block (Group ESPB) | Active comparator | ESP block will be applied in Group ESPB. The US probe will be placed longitudinally 2-3 cm lateral to the T5 transverse process. Three muscles from top to bottom; Trapezius at the top, rhomboid major in the middle, and the erector spina muscle at the bottom will be displayed over the hyperechoic transverse process. Using the in plane technique, the block needle will be advanced in the cranio-caudal direction and 5 ml of saline will be injected under the erector spina muscle and the block location will be confirmed. After the block location is confirmed, 40 ml of 0.25% bupivacaine will be administered (20 ml in each side). Receives: Other: Postoperative management |
| Thoracal paravertebral block group (Group TPVB) | Active comparator | After visualizing the T5 spinous process sagittally with the US probe, the probe will be placed 2-3 cm laterally. The ribs and transverse processes will be displayed as hyperechoic structures. Superiorly, the costotransverse ligament and anteriorly the pleura will be visualized. With the in-plane technique, the block needle will be advanced in the cranio-caudal direction until the costotransverse ligament is passed. 5 ml of saline will be injected and the block location will be confirmed. After confirming the location of the needle, negative aspiration is performed, and after observing the absence of CSF, blood and air, 40 ml of 0.25% bupivacaine will be administered, and it will be seen that the pleura is pushed down as the drug is administered (20 ml in each side). Receives: Other: Postoperative management |

Questions about this trial
What is this clinical trial studying?
A study testing Postoperative management in people with Cardiovascular Diseases, run by Medipol University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative pain scores (Numerical Ratin Scala; 0=no pain, 10=the worst pain felt) (time frame: Postoperative 24 hours period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05476393, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2023; AzTrials last refreshed its copy on 28 Oct 2026.
