Postoperative Nitrogen Excretion After Amino Acid-Induced Thermogenesis Under Anesthesia

Abstract

We compared nitrogen excretion before and after surgery in patients who received a saline or amino acid infusion during isoflurane anesthesia. The increase in heat production induced by amino acids reduced hypothermia, abolished shivering, and attenuated/normalized the postoperative nitrogen saving that occurred in patients who did not receive amino acids.
