USO DE DEXMEDETOMIDINA EN TÉCNICAS DE PUNCIÓN PARA ENFERMEDADES DEGENERATIVAS DE LA COLUMNA LUMBAR

ABSTRACT

Objective

To analyze the results of the use of dexmedetomidine (D) in the treatment of patients with degenerative diseases of the lumbar spine using puncture techniques.

Methods

The study included 77 patients who underwent surgical puncture for degenerative diseases of the lumbar spine with the use of alpha-2-adrenomimetic D: percutaneous laser denervation of the facet joints (n = 46) and posterolateral transforaminal endoscopic discectomy (n = 31). We assessed: the level of sedation using the Ramsay Sedation Scale (RSS) and the Richmond Agitation Sedation Scale (RASS); intraoperative dynamics of the cardiovascular and respiratory system parameters; the level of pain syndrome according to VAS.

Results

A high intraoperative level of sedation was determined, with RASS -2, -3 and Ramsay III, IV; when transferring a patient to a department (in 90 minutes) this parameter was RASS 0 and Ramsay II. There were no significant changes in central hemodynamics and respiratory depression. The minimum level of pain was determined immediately after surgery, at 30 and 60 minutes after surgery, and before transfer to the department (90 minutes): 6 (4;9); 10 (8;12); 12 (9;13); 16 (13;19) respectively. The absence of the need for additional analgesia on the first postoperative day was verified.

Conclusion

The use of D significantly reduces the level of pain, while maintaining the necessary verbal contact with the patient, and provides the necessary neurovegetative protection without respiratory depression or lowered hemodynamic parameters during the perioperative period.
