FIELD: medicine.

SUBSTANCE: invention relates to cardiovascular surgery and anesthesiology-resuscitation, and can be used to predict the level of early postoperative pain in patients after reconstructive interventions on the abdominal aorta. The method includes measurement of a complex of prognostically significant parameters: intraoperative diuresis, the value of the analgonociception index according to ANI monitoring, measured during laparotomy access, the presence of diabetes in the patient, the values of the total protein level in the biochemical analysis upon admission to the hospital before the operation, the amount of fentanyl administered during the operation, smoking for at least two months, use by the patientβ -blockers before surgery, with the subsequent calculation of the probability P of the development of pain in a patient upon awakening characterized by a value on the visual analog scale VAS > 3 points, according to the formula. If P value is equal to or higher than 50%, it is concluded that there is a high risk of developing pain syndrome upon awakening of more than three points on the VAS scale.

EFFECT: method allows to improve the quality of anesthesia, reduce the number of complications associated with pain syndrome, reduce the patient's period of stay in the hospital by the possibility of correcting the scheme of using painkillers by obtaining a prognostic assessment of the occurrence of acute pain syndrome at the preoperative and intraoperative stages.
