This study in a rat model of pulmonary metastasis demonstrates that some anesthetics, but not others, increase susceptibility to tumor metastasis, apparently by suppressing natural killer cell activity. Ketamine was most deleterious, and its effects were prevented by peripheral blockade of beta-adrenoceptors combined with low levels of immunostimulation.

The addition of spinal blockade to general halothane anesthesia markedly attenuates the promotion of metastasis by surgery.

PCO measurement compared well with the lithium dilution method and can be considered an accurate technique for measuring beat-to-beat CO with limited risk to the patient.
