Local anesthesia numbs a small, specific area of the body so selected procedures can be performed without pain in that area. This article is general education and cannot account for an individual patient, procedure, medication list, or surgical plan.
Key takeaways
- Anesthesia plans are tailored to the procedure, patient health, and expected recovery needs.
- Anesthesia professionals monitor and manage vital functions throughout the procedure and early recovery.
- Tell the team about prior anesthesia problems, medicines, allergies, sleep apnea, and relevant medical conditions.
- Recovery and activity restrictions differ by anesthesia type, so follow your specific discharge instructions.
What local anesthesia does
A local anesthetic blocks sensation in a limited area. It is commonly used for smaller procedures such as certain skin procedures, wound repair, or other interventions where only a small area needs to be numb.
Will you be awake?
Patients are generally awake with local anesthesia. They may feel pressure, movement, or touch even though sharp pain in the numbed area is blocked. In some situations, local anesthesia is combined with sedation.
For additional context, see What Is General Anesthesia?, which explains the next related part of the perioperative pathway.
How it differs from regional anesthesia
Local anesthesia targets a small area near the procedure. Regional anesthesia is placed near nerves to numb a larger region, such as an arm, leg, or the lower half of the body.
What to tell your clinician
Tell the team about allergies, previous reactions to anesthetics, medical conditions, and medicines you take. The clinician can explain what sensations are expected and whether sedation is part of the plan.
After the procedure
Numbness can persist for a period after the procedure. Follow the facility’s instructions about protecting the numb area and when normal activity is safe to resume.
Use your own surgical instructions
Perioperative instructions vary by procedure, facility, anesthesia plan, and medical history. If this page differs from instructions given by your healthcare team, follow your healthcare team and contact them with questions.
Using this information before your procedure
Use this guide to prepare questions rather than to choose an anesthetic technique on your own. Before surgery, confirm what type of anesthesia is planned, whether sedation is expected, how pain will be managed, and what restrictions apply afterward. If you have had severe nausea, a difficult airway, an allergic reaction, unusual awareness, or another concerning anesthesia experience, describe what happened as clearly as you can.
It is also helpful to make sure the anesthesia team knows about sleep apnea and CPAP use, heart or lung disease, neurologic conditions, pregnancy when relevant, all medicines and supplements, and alcohol or other substance use. These details can change preparation, monitoring, or recovery planning. The most useful online information is the information that helps you have a more specific conversation with the clinicians who know your procedure and medical history.
Frequently asked questions
Are you awake with local anesthesia?
Usually yes. Local anesthesia numbs a small area while the patient remains awake. Some procedures also use sedation, so the exact level of awareness depends on the planned combination of medications and the procedure.
How is local anesthesia different from regional anesthesia?
Local anesthesia numbs a relatively small area, while regional anesthesia blocks sensation in a larger region of the body. Both are different from general anesthesia, which produces unconsciousness.
Can local anesthesia have side effects?
Yes, although side effects are generally limited and serious complications are uncommon. Patients should tell clinicians about prior reactions, allergies, medicines, and medical conditions so the team can select an appropriate technique and monitor for problems.
