Comparison of the Effects of Ultrasound-Guided Combined Serratus Anterior Plane Block and Thoracic Paravertebral Block on Postoperative Acute Pain in Patients Undergoing Video-Assisted Thoracoscopic Surgery

E.Kurul-E1-22-2372

Video-assisted thoracic surgery (VATS) has become a common procedure in thoracic surgery. Severe postoperative pain may be encountered in patients undergoing VATS. Analgesic methods such as thoracic paravertebral block (TPVB), intercostal block, serratus anterior plane block (SAPB), and erector spinae plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In recent years, the frequency of application of plane blocks as a component of multimodal analgesia has been increased. ESPB and SAPB are some of them. There are two techniques for SAPB application. In Deep SAPB (DSAPB) application, a local anesthetic agent is given under the serratus anterior muscle. In the Superficial SAPB (SSAPB) application, the local anesthetic agent is given above the serratus anterior muscle. Since it is done by entering from the same point in two applications, it is possible to perform these two applications at the same time with a single needle entry. The mechanisms of regional analgesia techniques used after thoracic surgery operations are also different from each other. Therefore, it may be possible to obtain a more effective analgesic effect in patients by combining the mechanism of action of DSAPB and SSAPB, as in the multimodal analgesia method. This study seeks to evaluate the effect of TPVB and combined SAPB (CSAPB) after VATS.
