Video-assisted thoracic surgery (VATS) is frequently applied in thoracic surgery operations. VATS has become the standard procedure in minor and major lung surgeries. In recent years, regional anesthesia techniques have also been frequently applied to patients for pain relief. Thoracic paravertebral block (TPVB), erector spinae plane block (ESPB), and serratus anterior plane block (SAPB) are also among the regional anesthesia techniques frequently used in thoracic surgery. General anesthesia (GA) is the main method of anesthesia for thoracic surgery. However, GA can only inhibit the projection system of the cortical limbic system or hypothalamic cortex. GA cannot completely block the transmission of peripheral noxious stimulus to the central nervous system and cannot effectively inhibit the intraoperative stress response. With the addition of peripheral blocks such as TPVB, ESPB, and SAPB, more stable hemodynamics is expected by providing preemptive analgesia in patients. As a result of all these; In this study, we aimed to compare the intraoperative hemodynamic changes of patients who underwent preoperative ESPB in patients who will undergo VATS resection under GA with those who underwent postoperative ESPB.

Erector spinae plane block will be performed unilaterally, under US guidance, before the surgical operation, after the induction of anesthesia, and when the patient is placed in the lateral decubitus position.

Mean arterial pressure
Mean arterial pressure values will be recorded before anesthesia, before surgical incision, after surgical incision at 5th, 30th, 60th, 90th, 120th minutes, and after general anesthesia.
Time frame: Perioperative period
Heart rate
Heart rate values will be recorded before anesthesia, before surgical incision, after surgical incision at 5th, 30th, 60th, 90th, 120th minutes, and after general anesthesia.
Time frame: Perioperative period
Pain scores
Pain will be assessed at rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Pain assessment will be done at the 1st, 2nd, 4th, 12th, and 24th hours after surgery.
Time frame: First 24 hours after surgery
