[Neuroleptanalgesia, surgical trauma and immunity]

Immune status and hormonal homeostasis have been studied in 26 patients with larynx cancer operated on (laryngectomy, extended laryngectomy) under neuroleptanalgesia. It has been established that 3 and 7 days after the operation there was a decrease in plasma cortisol level and an increase in B- and T-lymphocyte count and theophylline-resistant T-lymphocyte count in the peripheral blood. In 4 patients with postoperative complications (pharyngeal fistulas) there was a reverse correlation between cortisol content and B-lymphocyte count and T-lymphocyte blast transformation.
