摘要

Introduction In our clinical practice,we are accustomed to dealing with perioperative hemodynamic and blood pressure changes on a daily basis.Intraoperative blood pressure variations outside of the accepted "normal" physiologic ranges are in fact very common.A recent publication analyzing intraoperative blood pressure data from electronic medical records found hypotension [systolic blood pressure (SBP) ＜ 80 mmHg for ＞ 5 minutes] in 26％ and hypertension (SBP ＞ 160 mmHg for＞5 minutes) in 20％ of 16,913 anesthetic cases[1].When we reflect upon our daily practice and look at these numbers,the following two questions arise.What is considered the "normal physiologic range" of intraoperative blood pressure and how much does intraoperative hypotension (IOH) really affect postoperative outcome?
