Scalp Block in the Functional Surgery of Patients with Parkinson’s Disease

Abstract

ABSTRACT

Introduction: Parkinson's disease is the second most common neurodegenerative disease affecting mostly during the sixth decade of life. It is a chronic disease of slow onset andasymmetric progression characterized by motor and nonmotor disturbances.

Objectives: To characterize scalp block as a safe and valid anesthetic technique for a functional surgery in patients with Parkinson's disease.

Methods: A descriptive, prospective and longitudinal study was performed on all the patients undergoing functional Parkinson's surgery at Centro Internacional de Restauración Neurológica in the period from June 2022 to June 2023. Hemodynamic variables, levels of conscious sedation, need for rescue analgesia, as well as incidence of trans-and postoperative complications, were evaluated.

Results: Sixty-one patients were studied. Arterial hypertension was the most frequent comorbidity. The evolution of the studied patients’ sedation status wasevaluated according to the Ramsay scale: 42 of them remained at sedation level 2 and 19 reached level 3. When applying the visual analog scale to evaluate pain intensity, patients with little pain predominated, followed by those with no pain. Only three presented moderate pain. No complications derived from scalp block were evidenced. 

Conclusions: Scalp block ensures hemodynamic stability, patient cooperation, trans-and postoperative pain control, as well as good postoperative clinical evolution.
