Antidiuretic hormone following surgery in children.

摘要: We studied 13 children subjected to elective tonsillectomy, 6 of whom (study patients) received supplemental intravenous isotonic saline during and after operation, 7 (controls) did not. Clinical biochemical evidence hypovolaemia was present in the control but not study patients. Plasma antidiuretic hormone (ADH) urine osmolality were higher controls (p less than 0.005 p 0.05 respectively). sodium concentration similar two groups. conclude that is principal stimulus ADH release following surgery that, addition replacement observed losses blood other fluids by appropriate composition, should be prevented administration maintenance quantities fluid, rather exacerbated fluid restriction, patients oral intake interrupted for more a brief period. Hypotonic free avoided because risk hyponatraemia.
