Zusammenfassung
Intraoperative Hypotonie ist im klinischen Alltag keine Seltenheit. Obwohl ein Zusammenhang
mit erhöhter perioperativer Morbidität und Letalität zu bestehen scheint, wird sie
oft zu spät oder gar nicht therapiert. Dabei gibt es eine Vielzahl an Prädiktoren
und technischen Hilfsmitteln, um Risikopatienten zu identifizieren und das perioperative
Management durch ein adäquates Monitoring und eine frühzeitige Therapie zu optimieren.
Abstract
-
Despite the high incidence of hypotension after anesthesia induction, awareness of
the need to adequately and above all rapidily treat this condition is not always present
in clinical practice.
-
There is strong evidence that even a short episode of perioperative hypotension can
significantly increase morbidity and mortality.
-
Many risk factors for the occurrence of hypotension are known. Patients should be
closely monitored and rapidly treated.
-
In patients at risk, the average arterial blood pressure should not exceed of 80 mmHg
perioperatively.
-
Pre-existing hypovolemia enhances hypotension after anesthesia induction. Since many
predictors are known, these should be applied and the volume status optimized before
initiation of anesthesia.
-
Ultrasound procedures can be used to quickly assess critical circulatory conditions.
-
To predict hypotension after anesthesia, the "collapseability index" of the inferior
vena cava is most likely to be used.
-
Even a less experienced user can judge the presence of severely restricted cardiac
function. The RUSH protocol has a high sensitivity and specificity for differentiating
different forms of shock.
