[Features of the hormonal regulation of water-electrolyte balance in patients with tumors of the chiasmatic-sellar area in the early postoperative period].

The response of water-electrolyte metabolism regulating hormones to neurosurgical stress was studied in 54 patients with tumors of the chiasma-sellar area of the brain. Three types of responses of hormones (the activity of renin, aldosterone, cortisol, and vasopressin) were revealed. Type I was characterised by a sharp activation of the hormones studied, type II by an absence of a response, type III by activation of renin and aldosterone and a decrease in vasopressin activity. Responses of types II and III were attended by deep disorders of water-electrolyte balance. The work substantiates the necessity of taking into account the state of the humoral mechanisms of regulation in conducting intensive therapy in neurosurgical patients.
