What Is Anesthesiology? Roles, Importance, Reasons to See


Anesthesiology is the medical speciality concerned with preventing and treating discomfort in the perioperative period (the time immediately before, during, and after surgery).

A local anaesthetic may be given by the same person doing your surgery if it is a minor one, such as when a tooth is extracted. An anesthesiologist doctor will provide anaesthesia for major surgeries and other invasive treatments.

Important of Anesthesiology

Anesthesiologists play a crucial role in the surgical process, making choices to safeguard and control important bodily systems. Physician anesthesiologists are present during the surgical process since they are experts in perioperative care, anaesthetic planning and administration. 

They have the expertise to assess, diagnose, treat, and manage a wide range of medical issues and deal with potentially fatal complications that might arise at any time during surgery due to their considerable training.

Role of an Anesthesiologist

There are crucial roles for anesthesiologists to play before, during, and after a surgical or other procedure:

  • Before surgery: Your anesthesiologist will evaluate your medical history, test findings, and fitness for surgery to create a customized anaesthetic strategy.
  • During surgery: To keep your organs, such as your lungs, heart, and kidneys, working properly during surgery, the anesthesiologist will keep a close eye on you, treat any pre-existing illnesses you may have, and give you any necessary fluids, blood products, or drugs. They may work alone or as part of a team that includes nurse anaesthetists and resident physicians specializing in anaesthesia.
  • After Surgery: To ensure your safety while feeling the effects of anaesthesia, the anesthesiologist will stay with you in the recovery room following surgery. The doctor or nurse will generally determine whether you’ve fully recovered from your anaesthetic and may be moved to a regular hospital room.

Anesthesiologists also play a crucial role in managing patients undergoing less invasive procedures or those who, like mothers in labor, do not need complete unconsciousness to give birth.

They help those who have just had major surgery recover in the ICU. Within a pain management team, they also aid those suffering from severe pain due to an accident or chronic pain.

Reasons to see

Many anesthesiologists specialize in caring for patients with long-term pain because of their expertise in pain management. Ask your primary care physician for a referral to an anesthesiologist who specializes in treating chronic pain if you have migraines, back pain, or pain from a disorder like fibromyalgia.

Some subspecialties of anesthesiology

The following are some anesthesiology subspecialties:


  • Cardiac anesthesia
  • Critical (intensive) care
  • Hospice and palliative care
  • Pediatric anesthesia
  • Neuro-anesthesia
  • Obstetric anesthesia
  • Pain management
  • Regional anesthesia/acute pain management

Is anesthesia the same as anesthesiology? 

When you have anaesthesia, you won’t feel anything when the doctor performs surgery or other invasive treatments. Anesthetics are painkillers that work by blocking nerve endings.

While certain anaesthetics numb specific areas of the body, others numb the brain to put patients to sleep for more invasive surgeries on the brain, chest, or belly.

Anesthesiology is the branch of medicine concerned with preventing and treating pain in surgical patients.

Anesthesiologists provide some of the best medical treatments in the world, and their training has kept pace with this expansion. 


Is an anesthesiologist a doctor?

A physician anesthesiologist is a medical doctor, the same as your surgeon or family doctor. They have completed between 12 and 14 years of schooling to become doctors, including undergraduate study and medical school.

Is an anesthesiologist a doctor?

Those anesthesiologists who have chosen to focus on interventional pain management, such as inserting neural/spinal cord stimulators and/or implanted pumps, execute most surgical procedures involving patients.

These days, anesthesiologists routinely conduct various minimally invasive surgical procedures, including sacroiliac joint fusions.
