The study aims to evaluate the analgesic efficacy of paravertebral block, mobilization speed, respiratory functions, and complication rates in patients who have undergone cardiac surgery and are monitored in the intensive care unit during the postoperative period.
The aim of this study is to evaluate the effects of a single-dose bilateral paravertebral block administered under ultrasound guidance on the recovery process after cardiac surgery. Effective management of postoperative pain in cardiac surgeries is crucial for enhancing patient comfort, reducing complications, and facilitating rapid recovery. Paravertebral block can be utilized as an effective method for pain management following cardiac surgeries. This technique provides extensive analgesic coverage in the thoracic region while reducing opioid consumption and its associated side effects. Additionally, it supports the preservation of respiratory functions, facilitates early mobilization, and may reduce postoperative complications. When performed under ultrasound guidance, the accuracy and efficacy of the block are enhanced, making it a safe analgesic option in cardiac surgeries. Studies have demonstrated that paravertebral block increases patient satisfaction and contributes positively to the recovery process. Therefore, it is a viable approach for postoperative pain management in cardiac surgery. This study will be conducted with a prospective, randomized, and controlled design. Patients will be assigned to two groups using a sealed-envelope method: the paravertebral block group and the control group. Patients in the paravertebral block group will receive a single-dose bilateral paravertebral block under ultrasound guidance before the induction of general anesthesia. The block will be performed at an appropriate thoracic level using 20 mL of 0.25% bupivacaine as the local anesthetic. Patients in the control group will receive a standard analgesia protocol. All patients will be monitored in the intensive care unit during the postoperative period, and the following parameters will be assessed: pain scores using the visual analog scale (VAS), total opioid consumption, extubation times, intensive care unit length of stay, Quality of Recovery-15 (QoR-15) score, and postoperative complications. Data will be collected during the preoperative assessment and throughout the first 48 hours postoperatively.

A single-dose bilateral paravertebral block will be administered under ultrasound guidance before the induction of general anesthesia. The block will be performed at an appropriate thoracic level using 20 mL of 0.25% bupivacaine as the local anesthetic.
Quality of Recovery -15 (QoR-15) score
The QoR-15 is a clinically acceptable and feasible patient-centred outcome measure after surgery. The score demonstrated good validity, reliability and responsiveness. The score ranges from 0 to 150. O refers to the worst recovery and 150 refers to best recovery.
Time frame: Postoperative 24th hours
Visual Analog scale (VAS) score
The Visual Analog Scale (VAS) score is a pain assessment tool. The score ranges from 0 to 10, with 0 indicating no pain and 10 indicating the worst pain ever experienced
Time frame: Postoperative 2nd, 4th, 6th, 12th and 24th hours
Opioid consumption
Total opioid consumption in first postoperative day will be recorded
Time frame: Postoperative 24th hours
Extubation time
Time frame from the end of the surgery to extubation will be recorded
Time frame: Time frame from the end of the surgery to extubation
