Why is hypothermia used in an open heart surgery?

History
1 answer:
Eva8 [605]2 years ago
4 0

Hypothermia is used widely during open heart surgery due to its cytoprotective effects.  In addition to this, other mechanisms of therapeutic hypothermia include suppression of free radicals, inhibition of destructive enzymatic reactions, reduction in metabolic requirements in low-flow regions, and inhibition of the biosynthesis, release, and uptake of excitatory neurotransmitters. Through these mechanisms, hypothermia provides a favorable balance between oxygen supply and demand, slows the onset of ischemic depolarization, decreases the release of ischemic-induced intracellular calcium influx, and suppresses nitric oxide synthase activity.

Hypothermia is widely used in open cardiac surgery not only to protect against perioperative brain ischemia that could potentially develop, but also the myocardium.

Morgarella [4.7K]

Answer:

A. global trade

Explanation:

Like the modern bubonic plague, scientists believe the Plague of Justinian spread through fleas. Studies indicate the plague may have originated in China or India and was then transported to the fertile valleys of Egypt through trade routes.

The plague is thought to have originated in Asia over 2,000 years ago and was likely spread by trading ships, though recent research has indicated the pathogen responsible for the Black Death may have existed in Europe as early as 3000 B.C.
