  • Title: [Anesthesia using clofelin in different types of arterial hypertension in middle-aged and elderly patients].

    Abstract:
    Clonidine in a dose of 2.5 to 3 mg/kg was used as a component of anesthesia in 150 patients aged 60 to 85. Essential hypertension of the second-third stages was diagnosed in 57% patients (group 1), systolic sclerotic arterial hypertension (SSAH) in 43% (group 2). Anesthesia was characterized by stable hemodynamics; however, analysis within the groups showed an increase of systolic and diastolic arterial pressure in 40% patients in group 2. There were no clinical signs of inadequacy of anesthesia. Remembering about the reduction of the reserve potential of the cardiovascular system in this cohort of patients, neurovegetative inhibition was supplemented by peripheral a-adrenoblocker droperidol, starting from the test dose of 1.25 and increasing it to 5 mg over the course of anesthesia; this led to stabilization of the peripheral and improvement of the central hemodynamics. Differences in the changes of central hemodynamics may be explained by specific features of circulation in patients with essential hypertension and SSAH, as well as by a higher tone of the sympathetic component of the CNS in SSAH patients.
