Objectives

Narrative objectives1

The cause of dehydration during surgery includes blood loss, vascular expansion due to anesthetic agents, or extravascular loss due to inflammation. It is essential for anesthesiologists to administer an appropriate fluid infusion to patinents, though quite challenging to identify the dehydration during general anesthesia because of the lack of thirstiness. Low blood pressure, tachycardia, scarce urine output, or respiratory variation of arterial pulse are well-known markers related to dehydration, however, these are also affected by other causes, thus more specific markers are needed.
Electrolyte free water clearance (Cw) reflects the degree of re-absorption in renal collecting duct and may possibly relate to the dehydration. The aim of present study is to inspect the relationship between Cw and dehydration and second, the relationship between dehydration and urine osmolality, urine gravity, urine sodium/potassium ratio, serum blood urea nigrogen/creatinine ration, serum osmolality. Finally, we aim at searching which marker is the best one to identify the dehydration.
