Why is hypothermia used in an open heart surgery?

History
1 answer:
Eva8 [605]3 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.

discuss the challanges faced by community corrections officials in monitoring offenders in community in South Africa​
Leona [35]

Community corrections officials in South Africa face several problems when monitoring offenders in communities such as:

  • Lack of manpower  
  • Lying by community members  
  • Danger to correctio official

Community correction officials are tasked with monitoring offenders who were not put in jail by the Court but were instead ordered to serve their sentence in communities by doing certain things.

In South Africa, some challenges these officials might face include:

  • Lack of manpower - because of high crime rates in South Africa, corrections officials may be assigned to too many offenders which would reduce the effectiveness of their monitoring.

  • Lies by community members - members of the community might lie to protect offenders when they commit fresh crimes or fail to do what the courts instructed them to do so that the offenders do not end up in jail.

  • Danger to correction official - South Africa has seen its fair share of violence against law enforcement officials. Corrections officials going into the community to monitor offenders can therefore put them at risk of being harmed by criminals in the community.

In conclusion, community corrections programs might have certain advantages but they can present various challenges to officials.
