Postoperative Visceral Pain
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain intensity after surgery | 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) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Length of Hospital Stay | From end of surgery to hospital discharge (up to 30 days) | The total time from the end of surgery to hospital discharge will be recorded for each patient. The duration will be measured in days (d) and used to assess postoperative recovery. |
| Postoperative Analgesic Use | From end of surgery to hospital discharge (up to 30 days) | Detailed records will be kept of the types of analgesics administered postoperatively, the total dosage of each drug, and the frequency of use per day. This measure will help assess pain management and medication requirements after surgery. |
