title: What is the definition of intraoperative hypotension in dogs? Results from a survey of diplomates of the ACVAA and ECVAA.
abstract: OBJECTIVE
  Determine arterial blood pressure range that diplomates of the American College of Veterinary Anesthesia and Analgesia (ACVAA) and European College of Veterinary Anaesthesia and Analgesia (ECVAA) use to define intraoperative hypotension in dogs and identify the threshold values used for intervention.
  
  
  METHODS
  Survey of veterinary anesthesia specialists.
  
  
  METHODS
  Diplomates of the ACVAA and ECVAA.
  
  
  METHODS
  ACVAA and ECVAA diplomates (n = 313) were invited to participate in an Internet-based survey regarding anesthetized healthy dogs undergoing two types of procedures (diagnostic or surgical).
  
  
  RESULTS
  There were 151 respondents to the survey; 70.2% were ACVAA diplomates and 29.8% were ECVAA diplomates. The majority of the respondents (70.9%) worked in academia while the others were in private practice (19.2%), or research, diagnostic or pharmaceutical fields (9.9%). Hypotension was defined (mean ± SD) by the respondents as systolic arterial blood pressure (SAP) <87 ± 8 mmHg for surgical cases and <87 ± 6 mmHg for diagnostic cases, or mean arterial pressure (MAP) <62 ± 4 mmHg for both types of cases. Arterial pressures reported to prompt treatment were SAP 85 ± 13 mmHg or MAP 61 ± 4 mmHg in surgical cases, and SAP 84 ± 11 mmHg or MAP 63 ± 8 mmHg in diagnostic cases.
  
  
  CONCLUSIONS
  There was agreement between ACVAA and ECVAA diplomates on the definition of intraoperative hypotension in dogs during anesthesia. The blood pressures used to define hypotension were similar to the pressures that would prompt diplomates to start treatment. Readers could infer that diplomates define hypotension as a clinical condition that requires treatment at the time of diagnosis.
