Hypotension - an unknown risk?

Studies show: intraoperative hypotension is a fact. Even short hypotensive episodes are associated with severe complications.

How best to characterize hypotension remains unclear, and there is no universal definition of hypotension. In a systematic review, for example, Bijker et al. found 140 definitions for hypotension in 130 articles.[1],[2]

Hemodynamic management

Hemodynamic management is a vital part of the perioperative phase. It can also be a challenge: hemodynamic instability is a constant danger during anesthesia and surgery. Fluctuations in blood pressure may presents themselves as decreases in systolic and mean arterial blood pressure. These hypotensive episodes might be missed by discontinuous upper arm cuff readings.[1],[2]

Why it is so important to detect blood pressure fluctuations immediately?

MAP<65 mmHg (low perfusion pressure) may lead to tissue hypoxia

During phases of hypotension, the brain, the heart, the kidneys and other vital organs can be deprived of blood flow resulting in tissue hypoperfusion and hypoxia. Acute kidney injury and myocardial injury can be caused by even short periods of hypotension and are leading causes of 30-day postoperative mortality. [1],[2]

Never miss a beat

The individual evaluation of the hemodynamic stability of each and every patient is essential in guiding goal directed therapy. This includes not only the monitoring of blood pressure and the mean arterial pressure (MAP), but also other determinants of the cardiac output like afterload, preload and contractility of the heart.
