[Cytotoxic activity of natural killer cells during balanced anesthesia with isoflurane versus total intravenous anesthesia].

Using two different anaesthetic techniques, the author have investigated the cytotoxicity in process during abdominal surgery. In these investigations, no significant differences have been demonstrated in the behaviour of the NK with the two techniques adopted. The increase noted in traceable to the mobilization of the N.K. of the extra vascular deposits. The increase of the cytotoxic activity is probably traceable to the action of the endogenous opiate substances.
