Anesthetic basics: simple facts you can use
Facing any procedure that involves an anesthetic? Knowing the essentials helps you feel calmer and make smarter choices. This short guide explains what anesthetics do, the main types, common side effects, and the exact questions you should ask before, during, and after care.
Types of anesthetics and when they’re used
There are four common categories:
Topical: creams or sprays (like lidocaine) used on skin or mucous membranes for minor procedures or to numb injections. Quick effect, short-lived.
Local: an injection that numbs a specific spot — dental work, small skin procedures, or stitches. You stay awake and usually leave the clinic the same day.
Regional: numbs a larger area of the body — think spinal or epidural anesthesia for childbirth or lower-limb surgery. It blocks pain while you may stay awake or lightly sedated.
General: makes you unconscious for bigger surgeries. Common drugs include propofol for induction and inhaled agents like sevoflurane to maintain anesthesia. Patients are closely monitored for breathing, heart rate, and blood pressure.
Practical safety tips and what to ask
Before your procedure, do these things:
- Make a clear list of all medications, supplements, and herbs you take. Some — like blood thinners, certain diabetes meds, or herbal supplements — change anesthesia plans.
- Tell your team about past problems with anesthesia: nausea, vomiting, bad reactions, or family history of malignant hyperthermia (a rare but serious reaction).
- Follow fasting rules. Typical guidance: no solid food 6–8 hours before general anesthesia; clear liquids may be allowed up to 2 hours prior. Your provider will give exact instructions based on the procedure and your health.
- Share health details: sleep apnea, heart disease, lung issues, pregnancy, or diabetes matter. These conditions affect monitoring and drug choices.
After the procedure, expect some common effects: nausea, dry mouth, sore throat after intubation, shivering, or temporary numbness and weakness where regional blocks were given. Most resolve within hours to a day. If you notice severe breathing trouble, chest pain, sudden swelling, or a high fever, seek emergency care right away.
A few extra practical notes:
- Arrange a ride home if you had sedation or general anesthesia. You won’t be cleared to drive.
- Ask about pain control options beforehand: will you get local long-acting blocks, oral meds at home, or a prescription? Mention any opioid sensitivity or prior bad reactions.
- If you take heart, blood pressure, or psychiatric meds (including MAOIs or SSRIs), ask whether to skip the dose on the day of surgery — only after talking to your doctor.
