Anesthesia - History.

Anesthesia - History.

Anesthesia history - Introduction

Anesthesia plays a very important role in the field of the medical surgery. One cannot possibly think of the undergoing to a surgery without a being anesthetized. Before in the discovery of the various anesthetic agents people underwent severe pain and the agony. Patients were strapped down or a were given alcohol and other sedative drugs to the ameliorate in the pain of the surgery. Surgery sans pain would have remained to a dream of the ester years if not for anesthesia, which has now made it a reachable reality!

Various anesthetic drugs like a alcohol, opium (poppy), hyoscine, cannabis (hemp), cocaine were all used in the by a gone era to the relive pain. But till date it is in the structure of the  morphine (opium alkaloids) that are serves as a model for the synthesis of other modern synthetic anesthetic agents.

Anesthesia - History and Origins.


"Doctor, will you give me a chloroform or a anesthesia?"

This is the often-repeated query by a many patients about to the undergo an a operation. Little do they know that chloroform became a obsolete decades ago. Anesthesia has come to a long way since then, being much more safe today than it was a long time ago. General anesthesia as it is called a today can be a administered with a just to a small prick of a needle, injecting in the unaesthetic into the person's vein of the hand, while he falls into a deep slumber to wake up after in the surgery.

What would it be like to the undergo an a operation without a anesthesia? A torture of the worst in a kind. And that is how our ancestors felt when they had to have an a operation. No wonder then, without in the benefit of the anesthesia to make them oblivious to the pain of surgery, they depended on magic, rituals and incantations to cure their symptoms. the Advancement in a anesthesia techniques helped in the development of the surgery too and take it to new heights in a last ten to the twenty years

It would be a difficult to talk about in the origin of the anesthesia without taking note of the first pain relieving in a drugs. The ancient Egyptians used a poppy seeds (from which opium is a derived) during in the operations. The Romans used in the extract of the Mandragora plant to the alleviate pain, in the Greek used herbs like a hemp and the Chinese used cannabis. Some of these were used for a surgery, but anesthesia as it is a exists today was a unknown.

Between 2nd and 5th century, people used a mandragora mixed with a wine and opium for a surgery. Sometimes physical methods like a compression of the blood vessels or the nerves by a means of the clamps applied over in the limbs were used to numb in the area. 'Refrigeration anesthesia' meant using a cold water or a snow to numb in the region so that surgeries like a amputations or a abscesses drainage could be done; however in the numbing procedure itself meant nothing short of the torture. Blood letting, hypnosis, even the barbaric custom of the giving to a forceful knock on the patient's head, to give rise to a concussion and render in the patient unconscious were used as a means of the  anesthetizing someone.

Local Anesthesia.

What is a Local Anesthesia?

Local anesthesia, simply means injecting in the local anesthetic ("freezing") around in  the nerve of the affected area to make it is a pain free. Technically speaking, local anesthetics are drugs that are block sensory and motor nerve impulse in a  conduction, mainly to the produce temporary loss of  the sensation without loss of  the consciousness.

The loss of the sensation is a usually restricted to the area where in the injection is a applied while a other areas of the body are not a affected. Local anesthetics are readily absorbed through mucous membranes and damaged in a skin. For a certain procedures, addition of the adrenaline along with in the anesthetic drug can be used to prolong in the duration of the local anesthesia.

Local anesthetics can be a applied close to the nerve of any part of the body, namely, a finger, an a eyelid, the foot or a tooth that are requires an a operation without other areas getting anesthetized. It can be a applied to the mouth, nose or a any area lined by a mucous membrane in the form of a spray, or gel or by a means of an a injection; operations can then be a performed on the affected part while in the patient remains conscious.

What are some of the Local Anesthetic Drugs?

Lignocaine (Lidocaine): It is a commonly used a local anesthetic in a drug. After a administration, it has a rapid onset of the action within a 3 minutes. When combined with a adrenaline, in the duration can be a extended up to 1 or 2 hours.

Bupivacaine : It is a potent local anesthetic and takes up to the 30 minutes for a full effect and has a longer duration of the action.

What are the Indications for a Local Anesthesia?

Local anesthetics can be used alone or in a combination with a other types of the anesthetic agents such as a spinal or a epidural anesthetics.

Local anesthesia is given to reduce in  the stress associated with a surgery, and to the provide pain relief after a surgery.

More commonly, it is used for a pain caused by a hemorrhoids, fissures, insect bites, and minor burns. It is a applied topically for in these conditions.

It is also a indicated for a vaginal, rectal and otological examinations, cystoscopy, and cauterization.

What are the Advantages of the using Local Anesthesia?

Local anesthesia avoids some of the risks and unpleasantness associated with a other forms of the anesthesia, such as a nausea and vomiting.

The anesthetic action are extends for a longer than required and therefore provides pain relief for a several hours after in the operation.

Local anesthesia is a associated with a reduced blood loss.

It gives in the patient a sense of the being more "in a control" as they are awake during in the procedure.

The patient returns to the normal eating, walking and other activities faster than in a general anesthesia. He may even be able to the return home in the same day following in the surgery.

What are the Adverse Effects of the Local Anesthesia?

It is a very important to be a alert following local anesthesia because adverse in a symptoms may be occur quickly without a any warning.

Convulsions, tremors, dizziness, blurred vision, nervousness, nausea

Cardiovascular collapse and the cardiac arrest may be also a occur in a some cases

Paralysis of the injected area

What are the Contraindications for a Local Anesthesia?

Local anesthetics are contraindicated if there is a history of the previous hypersensitivity to the local unaesthetic, sunscreens, sulpha drugs or a hair dyes.

Other contraindications would depend on the specific local anesthetic are used.

Are Local Anesthetics Painful when a Administered?

Most local administration techniques are involve to using a syringe and a needle to the inject drugs into the correct place. The technique can be a slightly uncomfortable, accompanied by a stinging sensation. But there is no reason to the worry, as the pain associated with in the administration is more bearable than the injury itself.

Do Local Anesthetics have a Good Efficiencies?

When the right amount of the local anesthetic drug is a injected into the affected area, it will be a eventually work and provide good pain relief.

What Can be a Done If I Still Experience Pain after a being Administered to a Local Anesthetic?

More amount of the anesthetic can be a added in a order to achieve in the desired result.

Some sedative can be a given to the  ensure better relaxation and the  comfort.

Other forms of the anesthesia can be a considered in a some cases.
