Resumo
It is reported that over 50% of patients undergoing major abdominal surgery experience perioperative anxiety, which often triggers a vicious cycle of "anxiety-pain-gastrointestinal dysfunction" and significantly hinders postoperative recovery. Existing pharmacological and psychological interventions are limited by adverse effects such as respiratory depression, paralytic ileus, and poor patient compliance. While tran...Mostrar mais

Severity and scores of perioperative anxiety
Perioperative anxiety severity and scores will be evaluated at the following timepoints: pre- and post-intervention (T0-T5); 2 hours post-surgery (T6); postoperative days 1, 2, 3, and 7 (T7-T10); and one month post-surgery (T11)
Within one month postoperatively
Severity and scores of perioperative depression
Severity and scores of perioperative depression (HAMD-24) will be evaluated at the following timepoints: pre- and post-intervention (T0-T5); 2 hours post-surgery (T6); postoperative days 1, 2, 3, and 7 (T7-T10); and one month post-surgery (T11)
Within one month postoperatively

Within one month postoperatively
Pain intensity
Pain Intensity (Numeric Rating Scale\[NRS\]) will be assessed at the following timepoints: 2 hours post-surgery (T6); postoperative days 1, 2, 3, and 7 (T7-T10); and at the one-month postoperative follow-up (T11)
