Comparison of the Efficacy and Safety of Fixed-rate Basal Infusion Mode and Time-programmed Decremental Background Infusion Mode of Intravenous PCA Following Mixed Surgery

Perioperative pain management affects patient recovery. However, the rate of moderate to severe postoperative pain is as high as 73.8%, which hinders recovery and increases the risk of complications. Although opioids are the first-line analgesics, excessive use leads to adverse reactions. The traditional fixed-rate PCA mode is difficult to match the changes in postoperative pain. This study will compare different PCA mode optimization strategies, assuming that they can reduce opioid dosage, improve analgesic effect, and reduce adverse reactions, providing high-quality evidence-based basis for postoperative analgesia and promoting individualized and intelligent management.

Regional Analgesia Techniques for Laparoscopic Cholecystectomy

This single-center, prospective, randomized controlled trial aims to compare the effects of paravertebral block (PVB), external oblique intercostal (EOI) block, and intravenous patient-controlled analgesia (PCA) with tramadol on postoperative pain and opioid consumption in patients undergoing elective laparoscopic cholecystectomy. The primary endpoint is total tramadol consumption within 24 hours postoperatively. Secondary outcomes include pain scores, additional analgesic use, incidence of nausea/vomiting, mobilization time, and length of hospital stay.

Erector Spinae Plane Block v.s Patient Controlled Analgesia in Correction Surgery for Idiopathic Scoliosis

Scoliosis correction surgery involves extensive surgical wounds, intense intraoperative stimulation, and severe postoperative pain, often necessitating the use of potent opioids. However, there is a critical clinical need for effective pain management strategies that both ensure sufficient analgesia and minimize opioid-related adverse effects. The Erector Spinae Plane Block (ESPB) has shown promise as an effective analgesic technique, but its application in scoliosis correction surgery has not been reported.We hypothesize that ESPB provides superior postoperative analgesia compared to patient-controlled intravenous analgesia (PCA) pumps. Specifically, ESPB is expected to significantly reduce postoperative pain scores, decrease perioperative opioid consumption, and mitigate opioid-related side effects. This study is a randomized controlled trial involving 40 participants undergoing scoliosis correction surgery, randomized into two groups: the ESPB group and the PCA group. The primary outcome measure is the resting pain score at 2 hours postoperatively, which will be used to evaluate the efficacy of ESPB. Secondary outcomes include perioperative opioid consumption and the incidence of opioid-related adverse effects. The study aims to provide evidence for ESPB as an innovative and effective method for postoperative analgesia in scoliosis correction surgery.
