[The central hemodynamics and hormonal status before, during and after urologic operations in children].

Urological operations in children are made as a rule to correct congenital malformations. The prevention of operative injury to the child' body is secured only in conditions of adequate anesthesiological defense. This is possible only in availability of rapid information on cardiovascular, oxygen metabolic and hormonal statuses. Central hemodynamics, oxygen metabolism and hormonal findings have been summarized for 89 children. The above parameters were measured before and during plastic reconstruction of the upper urinary tract. Initially hyperkinetic hemodynamics because of inadequate premedication to control psychoemotional lability, changed for stable and hypokinetic circulation to the end of the operative intervention as a result of neuroleptanalgesia. Eukinetic trends were induced by balanced promedol analgesia throughout the operation. Concentrations of hydrocortisone, aldosterone and STH were on the increase, while T3 and T4 levels lowered. Hyperkinetic and eukinetic hemodynamics were observed postoperatively after neuroleptanalgesia and balanced promedol-including analgesia, respectively.
