[Mechanisms of the effect of general anesthesia with barbiturates on immunity].

The effect of short-acting barbiturates on the number of theophylline-resistant and theophylline-sensitive T-lymphocytes in donors and patients with lung cancer on the function of spontaneous and induced donor regulators as well as the concentration of cyclic nucleotides and T-lymphocytes in donors has been studied in vitro. The effect of general anesthesia with barbiturates on the number of lymphocyte populations and subpopulations in the peripheral blood of somatically healthy patients with minimum surgical trauma has also been assessed. These studies as well as previous investigations serve the basis for elucidating the impact of general anesthesia with barbiturates on the immunity.

[A method of modified neuroleptanalgesia in lung surgery].

A modification of neuroleptanalgesia (NLA) has been developed to be applied in operations on the lungs. It is based on the inclusion of indomethacin and diazepam into premedication, on the bolus administration of phentanyl, droperidol, and diazepam prior to the most traumatic stages of the operation, and on the subsequent infusion of phentanyl and droperidol. The modified technique of NLA has been applied in operations on 19 patients with lung cancer.
