Through this quantitative, multivariate factorial experimental parallel randomized clinical trial, the investigators analyzed the effectiveness of pre-anesthetic assessment and pain neuroscience education in reducing anxiety, stress, and pain levels in patients undergoing elective total abdominal hysterectomy.
Hysterectomy is a common surgical procedure with a low risk of major complications. However, some women experience long-lasting complications, including chronic postsurgical pain, which can have a negative impact on their quality of life. The population will be made up of women with elective total abdominal hysterectomy scheduled surgery at the University Hospital of Puebla BUAP, in the city of Puebla, Mexico. Then the investigators will carry out an pre-anesthetic evaluation will be carried out and an pain neuroscience education session will be carried out. Once patients are ready for surgery, the investigators will carry out an invasive monitoring will be performed in the post-anesthesia care unit. The blood pressure of the participants will be monitored non-invasively. They will also be monitored with electrocardiogram and pulse oximetry.

One face-to-face Pain Neuroscience Education (PNE) session was delivered by a professional certified in PNE, with a duration of approximately 35 minutes. The session addressed the neurobiology and neurophysiology of pain, central sensitization, cortical representation of body regions, pain-related changes in body perception, and psychosocial dimensions of pain. Participants also received standard pre-anesthetic assessment, identical to the usual care group.
Usual care consisted of standard pre-anesthetic assessment and routine perioperative management, including analgesic medication administered before, during, and after hysterectomy, according to institutional protocols and the clinical judgment of the attending physician.

Change in Visual Analog Scale-Pain (EVA)
Pain intensity at rest was assessed using a 10-cm visual analog scale (VAS), ranging from 0 (no pain) to 10 (worst imaginable pain). Higher scores indicate greater pain intensity.
Time frame: Baseline (preoperative), 1 hour postoperative, and 8 hours postoperative
Change in Perceived Stress Scale - 14 items (PSS-14)
Perceived stress was assessed using the 14-item Perceived Stress Scale (PSS-14). Each item is rated on a 5-point Likert scale (0-4), yielding a total score ranging from 0 to 56, with higher scores indicating greater perceived stress.
Time frame: Baseline (preoperative), 1 hour postoperative, and 8 hours postoperative
Change in Beck Anxiety Inventory (BAI)
Anxiety symptoms were assessed using the Beck Anxiety Inventory (BAI), a 21-item self-reported questionnaire. Each item is scored from 0 to 3, with total scores ranging from 0 to 63. Higher scores indicate greater anxiety severity.
Time frame: Baseline (preoperative), 1 hour postoperative, and 8 hours postoperative
