Anaesthesia Profile Image

Anaesthesia

Anaesthesia is a state of temporary loss of sensation or awareness that is induced for medical purposes. It may include analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), or unconsciousness.

Anesthesia enables the comfortable performance of medical operations that would otherwise cause severe pain. There are different degrees of anesthesia avaliable for the doctor to choose. Their decision is based on multiple factors such as whether it is appropriate for the procedure as well as for the patient. 

The three types of anesthesia that exist:

  • General anesthesia results in unconsciousness and a complete lack of sensation.
  • Sedation inhibits without resulting in loss of consciousness.
  • Local anesthesia, which blocks sensation in an isolated part of the body. 


Why anaesthesia is used during medical surgeries: 

  • To induce temporary loss of consciousness and simulaneously, cause memory loss
  • Analgesia
  • Relaxation of muscles
  • Avoiding the sensation of pain during and just after surgery

 

 How anesthesia was founded:

In the past, people used to make use of alcohol to numb pain. They found that alcohol helped relax the patient, allowing them to carry out the procedures smoothly. However, vomitting was a side-effect that people were not able to solve. They transitioned to utilising cocaine and other drugs, after which they progressed to employ the drugs that we use as anesthesia today.

Interesting facts about anaesthesia

  • Smokers may require a greater dosage of anaesthesia compared to non-smokers. The smoke from cigarettes are known to result in respiratory issues, which disrupts the patient's tolerance for pain medication. 
  • Overweight people may have a greater chance of complications due to the fact that breathing problems might interfere with the procedure.
