An anesthesiologist is a healthcare provider who specializes in giving anesthesia, which is the medication that prevents you from feeling pain during operations or surgery. Your care is provided by anesthesiologists prior to, during, and following the surgery.

Before surgery, anesthesiologists consult with you and your surgeon to evaluate your health and make recommendations that will guarantee the safe and efficient administration of anesthesia. Throughout the procedure, they keep an eye on your vital signs, including how well your heart and lungs are functioning while you're asleep. Following the procedure, they tend to you to make sure you're as comfortable as possible as you heal.

Additionally, anesthesiologists are essential in the care of patients undergoing minor surgery or who might not require general anesthesia, such as laboring women who must be conscious and aware but who also need careful pain control. Patients with severe pain from an injury, as well as those with chronic or recurrent pain like migraines or persistent back issues, can benefit from them.

What Is An Anesthesiologist?

Similar to surgeons and primary care doctors, anesthesiologists are medical professionals. They have the knowledge and skills to comprehend and treat the full human body, and their areas of expertise are anesthesia care, pain management, and critical care medicine. Twelve to fourteen years of school, including medical school, and twelve to sixteen thousand hours of clinical training are required of anesthesiologists.

In addition to providing anesthesia, managing the Anaesthesia Care Team, and guaranteeing the highest level of patient safety, anesthesiologists evaluate, supervise, and monitor the treatment of patients prior to, during, and following surgery.

Critical care medicine, pain management, and anesthesia care are the areas of expertise for anesthesiologists.

What Types Of Anesthesia Do Anesthesiologists Provide?

The following kinds of anesthesia care are typically provided by anesthesiologists:

  • General anesthesia: This type of anesthesia is given through an anesthesia mask or IV and makes you lose consciousness. It is used for major operations, such as open-heart surgery or a knee replacement.
  • Monitored anesthesia or IV sedation: You experience relaxation and may have varying degrees of consciousness after receiving IV sedation. The degree of sedation used during an operation can vary, ranging from minimal (which leaves you sleepy but able to communicate) to deep (which causes you to lose all memory of the treatment). This type of anesthesia is generally used for minimally invasive procedures such as colonoscopies. Local or regional anesthesia is occasionally used in conjunction with IV sedation.
  • Regional anesthesia: An injection or a thin tube known as a catheter is used to administer pain medicine to numb a broad area of the body, such as the waist down. The affected area will be numbed, but you will still be conscious. This type of anesthesia, including epidurals and spinal blocks, is often used during childbirth and for surgeries of the abdomen, arm, or leg.
  • Local anesthetic: This injection numbs the part of the body that will be used for the surgery. There won't be any discomfort, but you'll be awake and aware. This is frequently used for operations including fixing a fractured bone, stitching a deep wound, and removing moles.

What Does An Anesthesiologist Do?

Your physician anesthesiologist, like your primary care physician, takes care of any medical issues (blood pressure, diabetes, asthma, heart diseases) while giving you an anesthetic that renders you or a portion of your body pain-free during the treatment. 

While you're unconscious and having surgery or other invasive procedures, anesthesiologists work to safeguard your body parts from harm by ensuring they're well-padded and shielded.  Anesthesiologists have significant tasks before, during and after a surgery or procedure:

  • Before Surgery: Your anesthesiologist will ask you extensive questions about your health, examine you, and go over test results in the days or weeks leading up to your surgery to make sure you are fit for the procedure. You can ask the anesthesiologist any questions you have regarding the procedure and anesthesia. Tell the anesthesiologist about all of your medical conditions, including asthma, diabetes, and heart disease; the medications you use, including prescription, over-the-counter, and herbal supplements; and any past anesthesia-related issues or concerns. Make use of this time to inquire. You'll feel more at ease and self-assured as you get ready for surgery if you understand your care. For you, your anesthesiologist will design a personalized anesthesia plan to guarantee a safe and successful procedure.
  • During Surgery: During surgery, your anesthesiologist keeps an eye on your vital signs, takes care of your medical issues, and gives you fluids, blood products, and medications to support your body's functions, including the heart, lungs, and kidneys. They could operate independently or as part of a care team for anesthesia that includes aspiring physician anesthesiologists or nurse anesthetists.
  • After Surgery: Following surgery, the anesthesiologist oversees other medical staff members and keeps an eye on your recovery, including your breathing, circulation, level of consciousness, and oxygen saturation. They are also readily available to answer any questions or address any concerns. When the anesthesia wears off and you are ready to be discharged from the intensive care unit or transferred to a regular hospital room, it is usually the anesthesiologist who makes the decision. In addition to planning your recuperation, the anesthesiologist might also help with pain control once you return home.

What Role Do Anesthesiologists Play In The Management Of Chronic Pain? 

Pain management is the specialty of anesthesiologists, and some of them concentrate on treating patients with chronic pain. If you experience persistent pain, such as headaches from migraines, backaches, or discomfort from fibromyalgia, ask your doctor about referring you to an anesthesiologist who specializes in treating chronic pain.


It can be distressing to require surgery or another invasive operation. Rely on the specific training and experience the anesthesiologist has to ensure your safety throughout the procedure. An anesthesia strategy tailored to your needs will be created by them. Asking your anesthesiologist questions is not anything to be terrified of. To make you feel more relaxed and confident about your procedure, they are available.
