The effect of ultrasound-guided intercostal nerve block on postoperative analgesia in thoracoscopic surgery: a randomized, double-blinded, clinical trial.

Background: Intercostal nerve block (ICNB) is a very effective analgesic method. We aimed to explore the effect of preemptive analgesia with ultrasound-guided intercostal nerve block on postoperative analgesia in thoracoscopic surgery.

Methods: 126 patients, aged 18-70 years, with American Society of Anesthesiologists (ASA) physical status I-II and scheduled for thoracoscopic pulmonary resection were enrolled in this study.
