What Are The Four Main Types Of Anesthesia – You Need To Know!

Human health can never be predicted and has unstable nature, which often goes in worst condition to good. One may experience several health conditions where doctor usually prescribes to operate the body for curing such issues. For example, if you are suffering from a tumor or appendix, then the operation is the only means to cure such disease. Shivering and fear of surgery is natural to every individual today, but that with several procedures, where one might not be able to experience any worst condition.

About Anesthesia

While getting prepared for surgical operations patients are usually injected an anesthetic or called as anesthesia. Such a procedure is given to the patient for reducing the pain or making the patient feel nothing during the surgical procedures. Anesthesia is divided into three main categories including general anesthesia, local anesthesia, and regional anesthesia.

Local Anesthesia is an option that is usually performed before short or minor surgical procedures on the body such as skin subcision done on the face. With such anesthesia, the patient feels less pain sensation on the area of the body where the operation is performed and here they would ultimately be in conscious and would remember and experience all the procedures adopted.

What Are The Four Main Types Of Anesthesia?

Regional Anesthesia is a general procedure that is given to numb the entire body including legs and arms or lower half of the body, especially given during childbirth. It is divided into two different categories such as Spinal anesthetic and epidural anesthetic.

A spinal anesthetic is one of the most used surgical procedure applied mostly on the abdomen and lower limbs.  Here the lower back portion is injected and numbs the lower part of the body.

Epidural anesthesia is usually practiced to conquer the pain of childbirth. This is applied to space throughout the spinal cord by a small catheter rather than injecting procedure through needles.

General Anesthesia

To the terms of anesthesia, General Anesthesia is the most common procedure used today that is another medical condition related to coma, not a type of sleep where the patient remains unconscious and does not responds. The standard procedures adopted for such method includes intravenously or through inhaled form, where the patient goes to sleep and does not feel any pain. Intravenous anesthesia is a standard method that requires a local anesthetic to put a small cannula on the hand or arm, done at several places mostly in operation theatre, and from that place, propofol or pentothal injection is given to patient that takes them to sleep.

Inhaling anesthetic method is the second style where an anesthetic usually holds a mask over the mouth and nose segment before the operation procedure and makes patient to breath sevoflurane gas that is also an anesthetic gas and only takes five to seven breaths to make patient sleep. In a recent study conducted on several adults throughout the world, they preferred to choose the inhaled form of anesthesia just because of fear of needles. All such steps are mostly done by a trained anesthesiologist or a doctor that monitor all conditions of the patient including their pulse rate and breathing procedure.  These procedures are under use since 1842 and very much successful today to give painless operation.

Possible Side Effects For Anesthesia

It looks good while using anesthesia during operation procedures but that might cause several types of side effects on the health after operating patient. Not every patient might receive side effect with that but still those who experience; it does not lasts for a long time and gets cured after some duration. Common negative sides that may arrive usually include:

• dizziness
• memory loss condition
• nausea and vomiting
• feeling cold
• a sore throat
• soreness
• Urine infection

Risk factors for Anesthesia

Overall the use of anesthesia to the patient is considered as very safe, whatever be the condition of that patient. So while going for anesthesia there is no risk at all, it is the surgical operation that creates uncertainty for patient health. Modern varieties of general anesthesia available today with medical science are incredibly safe intervention. However, old age persons going under last surgery are highly prone to receive side effects and health risk and can arrive in the form of a heart attack and even brain stroke. Some special circumstances raise the risk to the patient experiencing a general anesthetic including

• alcoholism
• drug allergies
• seizures
• diabetes
• sleep apnea
• kidney or lung infections
• high blood pressure
• smoking
• obesity or overweight condition of the body

How Does It Work? 

The specific mechanisms that combine to create the condition of general anesthesia are not known yet, however, according to its correct theory, the process is influenced through making changes to vital protein membranes present inside the brain that expands the protein synthesis through the medicines patient is exposed to. Preferably than a particular molecule working at a single site to respond, there are categories of compounds available that deliver varied effects including amnesia and analgesia. General anesthetic medicines range to different groups including sevoflurane. Within the central nervous system of the body public anesthetic act in various manners. The critical body systems influenced through such measures include spinal cord, Thalamus, Cerebral cortex, and Reticular activating system. There are tons of untold mysteries related to general anesthesia, but still, they stand to be one of the essential factors in medical science and is used with no single death rates due to anesthetic procedures.

Why is General Anesthesia Important?

The key factors influencing the use of local and general anesthesia is also the reason due to a patient health condition, age, and type of surgical procedures to adopt. However, general anesthesia might cause more complications in the end when chosen over local anesthesia. Still, the use of general anesthetic is carried due to:

• Surgical procedures that are of a complex nature and time taking
• Might cause colossal blood loss during the system
• Might affect the breathing process especially during chest surgery
• When a patient is not feeling comfortable
• The patient young

Further, it is also introduced due to

• unconsciousness
• memory loss
• analgesia
• skeleton muscle relaxation
• immobility

 

How Many Stages Of Anesthesia Are There?

In brief, there are four different stages of anesthesia determined, and that has got various amendments to the changes to medical science technology. From time-lapse, it has improved the recovery phase, its safety procedures, and onset speed.

Stage 1

This is the first phase observed before the anesthesia and often called the introduction stage. That arrives between Command of the medicine given and the loss of awareness, here patient experiences stage ranging between amnesia to analgesia.

Stage 2

One may experience excitement and loss of consciousness during such phase and even make some delirious activity. Blood pressure and breathing process might become enhanced and might also cause nausea and pupil dilation. Here a risk of choking may also happen due to inconsistent breathing process. However, modern medicines available today might reduce such risk occurrence.

Stage 3

This is the stage when the patient is ready for operation procedures after giving them injected anesthesia, which also arrives with no nausea and controlled breathing process.

Stage 4

It is also called as overdose stage that arrives due to excess medication is given and might lead to cardiovascular collapse. The whole purpose of the anesthesia process is to resist patient from reaching stage four and escape the risk caused.

Whenever a patient goes for operation and anesthesia is given, the doctor might observe various aspects of their health condition including blood pressure, heart rate, body temperature, blood oxygen level, breathing, and Fluid levels. Such measures are checked to analyze the situation and give patient medications accordingly.

They would ensure that during an operation procedure the patient remains asleep and does not feel any pain during the surgical process. As soon as surgical procedure gets completed the entire anesthetic medicines would be stopped by the doctor and patient is transferred to the recovery room, where they would wake up slowly.  The doctors would make a natural eye on patient condition would ensure that no complications arrive from anesthetic medicines or due to surgery.

Anesthetist and doctor’s team ensure that patient does not experience any side effect in the end and they might several questions regarding any allergic reactions to the body if the patient consumes liquor or smokes, have any worst experience due to anesthesia in the past, and the medications patient is taking on several occasions.

Conclusion

So these were some essential and fundamental points about anesthesia procedure. There are untold stories concerning such medications and is always talk in medical science. So if you ever go for any surgical operation procedure do not fear about the needles or any side effect because they are entirely safe on patient health. Our article is just for knowledge purpose only, and the actual theory of anesthesia might vary in real, so do not take this topic as serious.
