Postoperative Acute Pain

A single-center, randomized, double-blind, placebo-controlled trial design will be adopted to investigate whether Anruikefon can significantly reduce the consumption of sufentanil via PCIA pumps within 48 hours postoperatively compared with placebo.

The goal of this clinical trial is to evaluate whether the addition of a Transversus Abdominis Plane (TAP) block improves postoperative outcomes in women undergoing cesarean section. The main questions it aims to answer are: Does the TAP block reduce postoperative pain scores compared with the traditional analgesic regimen used in our hospital? Does the TAP block decrease opioid consumption within the first 24 hours? Does the TAP block improve the 24-hour quality of recovery? Researchers will compare patients receiving the traditional analgesic regimen with patients who receive the TAP block in addition to standard care to determine differences in pain management, opioid requirements, and recovery quality. Participants will: Receive standard anesthetic and perioperative care for cesarean delivery. Be randomized to either the TAP block group or the traditional analgesic regimen group. Have postoperative pain scores assessed at predefined intervals. Have opioid consumption recorded within the first 24 hours. Complete a quality-of-recovery assessment at 24 hours postoperatively.

This prospective, randomized clinical study aims to compare the analgesic efficacy of the interpectoral-pectoserratus plane block and the serratus posterior superior intercostal plane block for postoperative pain management in patients undergoing breast cancer surgery. Both techniques are ultrasound-guided regional anesthesia methods targeting different interfascial planes of the thoracic wall. The study will evaluate postoperative pain scores, opioid consumption, Quality of recovery and potential complications. The findings are expected to contribute to optimizing regional anesthesia strategies for enhanced recovery and improved analgesia following breast cancer surgery.

This study will evaluate whether giving sedation before spinal anesthesia, when performed with ultrasound guidance, reduces the risk of developing back pain after surgery. Spinal anesthesia is commonly used but may cause discomfort or persistent back pain in some patients. By comparing standard techniques, ultrasound guidance, and sedation, we aim to find safer and more comfortable approaches for patients undergoing non-obstetric surgery.
