The Effect of Oliceridine Patient-Controlled Intravenous Analgesia on Postoperative Chronic Pain After Video-Assisted Thoracoscopic Lobectomy
The Effect of Oliceridine Patient-Controlled Intravenous Analgesia on Postoperative Chronic Pain After Video-Assisted Thoracoscopic Lobectomy
The primary objective is to evaluate the impact of oliceridine versus sufentanil for perioperative analgesia on the incidence of chronic postsurgical pain (CPSP) in patients undergoing video-assisted thoracoscopic surgery.
The primary objective is to evaluate the impact of oliceridine administered via patient controlled analgesia device（PCA）versus sufentanil administered via PCA on the incidence of chronic postsurgical pain (CPSP) in patients undergoing video-assisted thoracoscopic surgery.
