The Consultants and specialty society members disagree
with the survey statement “Deliberate hypotension techniques
may be used in high-risk patients” (i.e., for high-risk
patients without preoperative chronic hypertension or for
high-risk patients with well-controlled preoperative chronic
hypertension). However, NASS members are split equally in
their opinions between agree and disagree for patients without
preoperative chronic hypertension. Consultants and specialty
society members who agree that deliberate hypotension
may be used in patients without preoperative chronic
hypertension indicate that blood pressure should be maintained
on average within 24% (range, 0–40%) of estimated
baseline mean arterial pressure or with a minimum systolic
blood pressure of 84 mmHg (range, 50–120 mmHg).
