General Anesthesia

General anesthesia is a type of anesthesia that renders the patient unconscious. An anesthesiologist or nurse anesthetist administers it. The patient's breathing, heart rate, and blood pressure will be monitored closely during general anesthesia. This type of anesthesia is typically used in major organ surgeries or longer procedures.

Local Anesthesia

Local anesthesia is administered to numb a particular body area. It is often used in minor surgical procedures and dental work. It is not usually used for surgeries that require more extensive anesthesia.

Regional Anesthesia

Regional anesthesia is used to numb a more significant portion of the body. Such anesthesia is usually required for arms, legs, or midsection procedures. There are two main types of regional anesthesia:

Epidural Anesthesia

Administered in the epidural space, a small space between the spinal cord and the vertebrae. Spinal anesthesia: Administered directly into the fluid surrounding the spinal cord.

I am a passionate traveler, as if traveling were my full-time job. I like to change my surroundings and environment, like changing desktop wallpaper. Nature increases the concentration in my writing, which helps brainstorming flow in my blood. I have a cat named Kitana. She is the most desperate about traveling, more than any other cat. How do I know? If I miss any tour in any week, she literally destroys my clothing with her wolverine nails.

I and my cat also participate in extreme activities like surfing, biking, hill tracking, paragliding, boating, etc. She was always there in my accidents, injuries, and stitches. She always sits on my lap when it hurts me most. The funniest part is that she has experienced all my tattoos. She sleeps on my blanket when I go through any painful experience.

My hobbies and lifestyle added many pain and injuries to my life. That is why I have a lot of experience in dealing with different levels of pain and burn. It influenced me to become a pain expert and share primary suggestions to handle any unwanted situations that hurt.


  • How Does Anesthesia Work?

    The system is segmented into four stages:

    • Stage 1: Induction - Start taking the medication until sleep ensues.
    • Stage 2: Excitement or delirium.
    • Stage 3: Surgical anesthesia.
    • Stage 4: Overdose.

  • Spinal Anesthesia Uses What Kind Of Needle?

    Whitacre needles, such as those in 24, 25, 27, and 28 gauge sizes, are commonly employed for spinal anesthesia. Their pencil-point design may lower the risk of post-dural puncture headache, a complication. The Quincke needle, available in 23 and 26-gauge sizes, also presents another alternative.
