[Effect of dopamine administration on ICG-disappearance rate during prone position anesthesia].
We evaluated the effect of dopamine administration (3 micrograms.kg-1.min-1) on ICG-disappearance rate during prone position in 10 patients undergoing elective spinal cord surgery. Anesthesia was maintained with isoflurane and 50% nitrous oxide in oxygen. ICG-disappearance rate was determined at 3 points, i.e., the day before surgery, during prone position and during the administration of dopamine. Systolic arterial pressure showed no significant difference before and during dopamine administration. ICG-disappearance rate during prone position was significantly lower than the preoperative value. However, ICG-disappearance rate showed no significant difference during dopamine administration and preoperative period. We conclude that dopamine administration may attenuate the depressant effect of the prone position on the hepatic blood flow.
