简要总结
This study aims to investigate the factors influencing the risk of postoperative visceral pain in patients undergoing abdominal surgery. The goal is to develop and validate a predictive model for assessing the risk of postoperative visceral pain, in order to guide individualized preoperative interventions and pain management strategies.

- •Aged between 18 and 70 years;
- •Classified as American Society of Anesthesiologists (ASA) physical status II-III;
- •Expected surgery duration ≥ 2 hours.
排除标准
- •History of previous abdominal surgery;
- •Diagnosed with chronic pain;
- •Long-term use of analgesics or other psychotropic medications;
- •Preoperative emergency condition;

结局指标
主要结局
Pain intensity after surgery
时间窗: From end of surgery to 48 hours postoperatively
Pain intensity will be recorded at 6, 12, 24, and 48 hours after surgery. At each time point, the Numerical Rating Scale (NRS) pain score will be assessed both at rest and during coughing. Pain intensity was assessed using number rating scale (0-10, higher score represents worse pain intensity)
次要结局
- Postoperative Length of Hospital Stay(From end of surgery to hospital discharge (up to 30 days))
- Postoperative Analgesic Use(From end of surgery to hospital discharge (up to 30 days))
