Overview
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.
Interventions
- Other Observational assessment of clinical outcomes
This is a non-interventional observational study. No treatment or behavioral intervention is administered.
Primary outcome measures
- Pain intensity after surgery [Time frame: From end of surgery to 48 hours postoperatively]
Secondary outcome measures (2)
- Postoperative Length of Hospital Stay [Time frame: From end of surgery to hospital discharge (up to 30 days)]
- Postoperative Analgesic Use [Time frame: From end of surgery to hospital discharge (up to 30 days)]
