Operations or surgery involves pain. To carry out the operation successfully, doctors give anesthesia to the patients. The anesthesia are the drugs which reduce stress before the operation, relieve pain involved in the operation, cause a temporary loss of memory of the operation procedure and make the muscles powerless.
But how long does this essential state persist ? Because in the answer to this question lies the peace or anxiety of a person to undergo operation.
The duration of the effects of anesthesia drugs depends the type of the drug used, its dosage and careful monitoring of several vital factors which directly influence its effectiveness.
To handle such a crucial aspect during operation, a medical professional is dedicated. He is called An anesthesiologist. His job is to commence the process of anesthesia, monitor the vital parameters in the patient’s body during surgery and a successful recovery of the consciousness at the end.
Different Stages of Anesthesia:
| Stage | Duration | Physical Signs |
|---|---|---|
| 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 the drugs play an important role in the process of anesthesia. It is because some drugs can reduce pain, some stress and others can bring in unconsciousness. A careful injection of these drugs together is imperative.
Today’s anesthetic drugs used in the initial stages, can bring the 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.
To extend the state of anesthesia further, the patient is allowed to breathe a mixture of carefully controlled volatile anesthetic gases, oxygen, nitrous oxide. Mixture of medications can also be used depending on the requirement and the state of the patient. The inhaled gases reach the patient’s brain via blood or the lung and keep the patient unconscious for further duration of the surgery. This process stops only when the end of the surgery nears.
Recovery of the consciousness after surgery depends on the age, physical health state of the patient in general and the response of the body to the anesthetic drugs. It usually takes nearly 30 mins for the effects of the anesthetic drugs to fade away and for the patient to gain consciousness.

The word Anesthesia was coined by Oliver Wendell Holmes, Sr. in 1846.
I had a colon resection and removal of ovaries 4 weeks ago. I am wondering if the anxiety I have been experiencing since coming home is part of drug withdrawal from paid meds given at the hospital. I have always had anxiety and have been switched from Prozac to Paxil 3 days ago. I have also gone off valium which was used for 20+ years in small doses and there were some years I didn’t use it. The rolling of my stomach and the shakiness is really getting to me. My therapist says it’s because of the surgery and it will take time. I’m not sure. Any suggestions?
Every patient is different and will require different doses, types of anesthesia, etc., and each person can react differently which is why they are closely monitored by the anesthesiologist during surgery.
