|---|---|---|---|
| Primary | incidence of moderate to severe visceral pain within 24 hours postoperatively | at 6 hours, 12 hours, and 24 hours after surgery | Numerical Rating Scale (NRS) for pain: minimum 0 (no pain), maximum 10 (worst imaginable pain); higher scores indicate a worse outcome (greater pain intensity).The NRS scores for visceral pain at rest and during activity were assessed in parturients at 6 h , 12 h , and 24 h postoperatively. Moderate-to-severe visceral pain was defined as an NRS score of ≥4 (on a 0-10 scale) at any of these time points. |
| Secondary | Frequency of rescue analgesic use within 24 hours postoperatively | within 24 hours after cesarean section | |
| Secondary | The area under the curve (AUC) of NRS scores for visceral pain at rest and during activity within 24 hours postoperatively in parturients. | at 6 hours, 12 hours, and 24 hours after surgery | Numerical Rating Scale (NRS) for pain: minimum 0 (no pain), maximum 10 (worst imaginable pain); higher scores indicate a worse outcome (greater pain intensity) |
| Secondary | Pre- and post-intervention 6-item STAI-S anxiety scores | Pre-anesthesia , before operating room exit，at 6 hours、12 hours、and 24 hours after surgery | Six-item Short-Form State-Trait Anxiety Inventory (STAI-S6): the raw sum score ranges from 6 to 24.Higher scores indicate a worse outcome (greater state anxiety). |
| Secondary | NRS scores for visceral pain at rest and during activity within 24 hours postoperatively (at 6 h, 12 h, and 24 h after surgery) | at 6 hours, 12 hours, and 24 hours after surgery | Numerical Rating Scale (NRS) for pain: minimum 0 (no pain), maximum 10 (worst imaginable pain); higher scores indicate a worse outcome (greater pain intensity). |
| Secondary | Hydromorphone equivalent dose within 24 hours after surgery | within 24 hours after cesarean section | |
| Secondary | Effective PCIA pump presses within 24 h postop. | within 24 hours after cesarean section | The number of effective presses on the PCIA pump can be automatically counted by the pump's backend program. |
| Secondary | score of pain sensitivity measurement | before intervention in the pre-anesthesia room, immediately upon completion of surgery, and 24 hours postoperatively. | For the pressure algometer used to measure pain sensitivity, the relevant metric is the Pressure Pain Threshold (PPT). There is no universal minimum or maximum: values are device- and probe-dependent (theoretical minimum 0; e.g., 0-2000 kPa for a 1 cm² probe or 0-4000 kPa for a 0.5 cm² probe). Higher PPT scores indicate a better outcome (lower pressure pain sensitivity), whereas lower scores indicate greater pain sensitivity. |
| Secondary | NRS scores for incisional pain at rest and on movement within 24 hours after surgery. | at 6 hours, 12 hours, and 24 hours after surgery | Numerical Rating Scale (NRS) for pain: minimum 0 (no pain), maximum 10 (worst imaginable pain); higher scores indicate a worse outcome (greater pain intensity). |
| Secondary | Postoperative adverse reactions | within 24 hours after cesarean section | |
| Secondary | AUC of incisional pain NRS scores at rest and on movement within 24 hours after surgery. | at 6 hours, 12 hours, and 24 hours after surgery | Numerical Rating Scale (NRS) for pain: minimum 0 (no pain), maximum 10 (worst imaginable pain); higher scores indicate a worse outcome (greater pain intensity). |
| Secondary | Changes in maternal heart rate during cesarean section. | during surgery: operating room entry, post-CSEA, skin incision, fetal delivery, skin closure | maternal heart rate (beats/min) wil be measured solely by the operating room monitor |
| Secondary | Changes in maternal non-invasive blood pressure during cesarean section. | during surgery: operating room entry, post-CSEA, skin incision, fetal delivery, skin closure | non-invasive blood pressure (systolic/diastolic, mmHg) wil be measured solely by the operating room monitor |
| Secondary | Changes in maternal pulse oxygen saturation during surgery. | during surgery: operating room entry, post-CSEA, skin incision, fetal delivery, skin closure | peripheral oxygen saturation (SpO₂, %) wil be measured solely by the operating room monitor |
