"Comparison of Rhomboid Intercostal and Subserratus Plane Blocks Applied for Postoperative Analgesia in Video-Assisted Thoracoscopic Surgery With Thoracic Paravertebral Block"

Postoperative pain is a significant concern following video-assisted thoracoscopic surgery (VATS). Pain after thoracic surgery not only causes a strong stress reaction and adverse emotional experience but also affects postoperative rehabilitation. Hence, different analgesia techniques, including local anesthetic infiltration, intercostal nerve block, paravertebral block, and thoracic epidural anesthesia, have been described to attenuate the intensity of acute postoperative painparavertebral block (PVB) and Rhomboid intercostal block with sub-serratus plane block (RISS) are the two types of plane blocks used for postoperative analgesia after video-assisted thoracoscopic surgery (VATS). This prospective randomized controlled trial was performed to analyze the postoperative analgesic effects of ultra- sound-guided PVB and RISS block after video-assisted thoracoscopic surgery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Active Comparator: PARAVERTEBRAL BLOCK
After induction of general anesthesia and endotracheal intubation in the operating room, following the positioning of the patient for surgery, ultrasound-guided paravertebral block (PVB) will be routinely performed in our clinic using 0.25% bupivacaine solution at a dose of 0.5 ml/kg.
Procedure: PARAVERTEBRAL BLOCK
Hemodynamic data (mean arterial pressure, heart rate, oxygen saturation) will be recorded for all patients every 30 minutes during the intraoperative period, along with the amount of opioids used throughout the surgery. A patient-controlled analgesia device (PCA) will be connected to each patient 15 minutes before awakening, prepared with a 1mg/ml morphine solution, with a bolus dose of 2 ml and a lockout period of 15 minutes

  • PVB
Active Comparator: RHOMBOID INTERCOSTAL AND SUBSERRATUS PLANE BLOCK
After induction of general anesthesia and endotracheal intubation in the operating room, following the positioning of the patient for surgery, rhomboid intercostal block with sub-serratus plane block (RISS) will be routinely performed in our clinic using 0.25% bupivacaine solution at a dose of 0.5 ml/kg under ultrasound guidance.
Procedure: RHOMBOID INTERCOSTAL AND SUBSERRATUS PLANE BLOCK
Hemodynamic data (mean arterial pressure, heart rate, oxygen saturation) will be recorded for all patients every 30 minutes during the intraoperative period, along with the amount of opioids used throughout the surgery.
