Understanding Anesthesia

Almost all medical procedures involve some form of anesthesia which works and impacts risk differently.

Whether it's wisdom tooth removal, a diagnostic colonoscopy or a coronary bypass surgery - they all involve some sort of anesthesia.

Since we cover elective surgeries, we've made it a point to know as much about anesthesia as we can so you have the resources you need to have more confidence about your procedure or ask your healthcare providers any questions you might have.

Before & After Anesthesia

Before Your Procedure

Expect to make some changes around smoking, blood pressure medication, ingesting food / drink / supplements leading up to your procedure as per your doctor's orders.

After Your Procedure

Have someone drive you home from the medical facility, follow your recommended rest / pain management regimen and do not drive, operate equipment, consume alcohol or make any important decisions for a day or two while the anesthesia leaves your system.

4 Main Types of Anesthesia

In increasing strength - local, sedation, regional & general. We've compared them below so you can better understand how they work, what to expect, and what you need to consider about risks or recovery.

Local Anesthesia

Numbs a small area so you stay awake and feel little to no pain.

How is it administered?

Given by mouth, injection, or IV.

Commonly used in?

Colonoscopy, minor outpatient procedures, and dental procedures.

Side effects / risks?

Grogginess, nausea, and slower reaction time.

Regional Anesthesia

Blocks pain in a larger part of the body, like an arm, leg, or the lower half of the body.

Will I be awake?

Often yes, sometimes lightly sedated.

How is it administered?

Injected near a nerve bundle or spinal area.
