Abstract

Objective: whether this is repeated during removal of the 2nd ovary in elective ovariohysterectomy.To investigate the physiologic reactions after removal of 1st ovary and Study Design:Prospective study. Animals:Dogs (n¼10). Methods: anesthetized with propofol and iso iso during surgery on physiologic variables were analyzed using mixed linear models. Blood and urine samples were collected before anesthesia, before incision, before and after removal of ovaries with a 15 minute pause between ovary removal, and after abdominal closure. Plasma vasopressin and urinary noradrenalin and creatinine concentrations were analyzed.Dogs were premedicated with acepromazine, carprofen, and methadone andflurane. Blood pressure, heart rate, and end‐tidalflurane concentration were measured every minute. The effects of various events Results: greater than for the 2nd ovary because of an elevation in baseline. Similarly, the heart rate increased at the removal of the 1st ovary but not at removal of the 2nd ovary. Plasma vasopressin concentration increased at removal of both ovaries. Urinary noradrenalin/ creatinine ratio increased at anesthesia, removal of both ovaries, and was elevated at closure of the abdomen. End pressure and vasopressin concentrations changed in parallel using z comparison.The magnitude of blood pressure increase at removal of the 1st ovary was‐tidal isoflurane concentration did not change. Blood‐scores for Conclusions: concentration, and urinary noradrenalin/creatinine ratio did not differ between removals of the ovaries. Relative changes differed between repeated noxious stimuli, which should be considered in evaluation of methods at ovary removal.Peak values for blood pressure, heart rate, plasma vasopressin
