Effect of Anesthesia on Our Body
Operations or surgery involve pain. To carry out the operation successfully, doctors administer anesthesia to patients. An anesthesia is a drug which reduces stress before the operation, relieves the pain caused by the operation and causes a temporary loss of memory of the operation.
How long does this altered state exist?
The duration of the effects of anesthesia depends on the type of the drug used, its dosage and careful monitoring of several vital factors which directly influence its effectiveness.
There is a medical specialist to handle this crucial aspect of the operation. This person is called an anesthesiologist. His or her job is to administer the anesthetic drug, monitor the vital parameters of the patient’s body during surgery and ensure a successful recovery to consciousness at the end.
Different Stages of Anesthesia:
|Onset||Giving Anesthesia to loss of consciousness||Physical Signs|
|Excitement||From loss of consciousness to loss of eyelid reflexes||Irregular Heart beats and Breathing|
|Surgical Anesthesia||Loss of eyelid reflexes to depression of vital functions||Total Unconsciousness|
|Recovery or Danger||Respiratory and circulatory failure||No breathing and heart beat|
Duration of the Stages of Anesthesia:
The choice of drugs plays an important role in the process of administering the anesthetic. Some drugs can reduce pain, some stress and others can bring on unconsciousness. A careful administration of these drugs together is imperative.
Today’s anesthetic drugs used in the initial stages of an operation can bring a state of total unconsciousness from the onset, in 10-20 seconds, without any requirement for the state of excitement. The effects of these drugs stay for 5 to 10 minutes. After this time, the patient may recover.
The patient breathes a mixture of carefully controlled volatile anesthetic gases, oxygen and nitrous oxide. A mixture of medications can also be used depending on the requirements and state of the patient. The inhaled gases reach the patient’s brain via blood or the lungs and keep the patient unconscious for the duration of the surgery. This process stops only when the end of the surgery nears.
Recovery of consciousness after surgery depends on age, physical health, state of the patient in general and the response of the body to the anesthetic drugs. It usually takes nearly 30 minutes for the effects of the anesthetic drugs to fade away and for the patient to regain consciousness.
