The Levels of Anaesthetics in Heart Muscle During Heart Surgery

In the last few years, anaesthetic agents, Isoflurane used in heart surgery have shown some benefits to reduce the risk of heart muscle damage. Many research studies have been conducted to reveal the benefit relationship between Isoflurane and the risk of heart muscle injury during heart surgery. However, there is a knowledge gap regarding the optimal level of Isoflurane concentration to confer the benefit of heart muscle-protective properties. Therefore, this study is conducted to answer that question by measuring the Isoflurane concentration in the blood vessels. It also assesses whether Isoflurane concentration in the blood is correlated to the oxygenator exhaust level of Isoflurane in the heart-lung machine.
