Primary Outcome Measures :
  1. Effectiveness of amitryptyline in the prevention of post-operative pain in women undergoing total abdominal hysterectomy, twenty-four hours after surgery [ Time Frame: Twenty-four hours after surgery ]
    The postoperative pain will be measured twenty-four hours after surgery, using the visual pain scale (0 - no pain to 10 - very hard pain)


Secondary Outcome Measures :
  1. Intensity of acute postoperative pain six hours after the procedure [ Time Frame: Six hours after the procedure ]
    It will be measured using the visual pain scale (0 - no pain to 10 - very hard pain)

  2. Intensity of acute postoperative pain twelve hours after the procedure [ Time Frame: Twelve hours after the procedure ]
    It will be measured using the visual pain scale (0 - no pain to 10 - very hard pain)

  3. Intensity of acute postoperative pain twenty-four hours after the procedure [ Time Frame: Twenty-four hours after the procedure ]
    It will be measured using the visual pain scale (0 - no pain to 10 - very hard pain)

  4. Intensity of acute postoperative pain forty-eight hours after the procedure [ Time Frame: forty-eight hours after the procedure ]
    It will be measured using the visual pain scale (0 - no pain to 10 - very hard pain)

  5. Records of rescue analgesia [ Time Frame: From the end of the procedure until 48 hours after that ]
    Use of rescue analgesia with the infusion of morphine - It will be checked using the patient records at the hospital

  6. Compare surgical time (duration, in minutes) and frequency of intraoperative and postoperative complications [ Time Frame: From the end of the procedure until sixty days after that. ]
    Relationship between surgical time (duration) and complications occurrence

  7. Frequency of adverse effects [ Time Frame: From the end of the procedure until 48 hours after that ]
    Onset of adverse effects like migraine, sickness, numbness, vomiting, itching, etc

  8. Length of hospitalization [ Time Frame: participants will be followed for the duration of hospital saty, an expected average of 48 hours. ]
    Time between admission and releasing, in hours

  9. Effectiveness of amitryptyline in the prevention of post-operative pain in women undergoing total abdominal hysterectomy, six hours after surgery [ Time Frame: Six hours after surgery. ]
    The postoperative pain will be measured after six hours after surgery, using the visual pain scale (0 - no pain to 10 - very hard pain)

  10. Effectiveness of amitryptyline in the prevention of post-operative pain in women undergoing total abdominal hysterectomy, twelve hours after surgery [ Time Frame: Twelve hours after surgery ]
    The postoperative pain will be measured after six hours after surgery, using the visual pain scale (0 - no pain to 10 - very hard pain)

  11. Effectiveness of amitryptyline in the prevention of post-operative pain in women undergoing total abdominal hysterectomy, forty-eight hours after surgery [ Time Frame: Forty-eight hours after surgery ]
    The postoperative pain will be measured forty-eight hours after surgery, using the visual pain scale (0 - no pain to 10 - very hard pain)
