[Prevention of hemodynamic disorders during anesthesia in middle-aged and elderly patients with essential hypertension. Components of anesthesia. II].

Hemodynamic parameters were evaluated during various stages of anesthesia in two groups of patients aged 60-85 years with mild essential hypertension. In group 1, routine preoperative treatment with hypotensive drugs was carried out and in group 2 differentiated preoperative treatment with calcium antagonists was carried out with consideration for a hemodynamic type. Group I patients were operated on under traditional neuroleptic analgesia (NLA), group 2 under NLA with 40% lower drug doses than in group 1 and with addition of calcium antagonists.
