Regional vs. Local Anesthesia: Choosing What's Right for You

The pinch of a numbing injection lasts only seconds, but the decision behind it is much bigger. Local and regional types of anesthesia are often used for simple procedures where the patient wants to avoid total loss of consciousness and the risk factors associated with general anesthesia. 

If you’re trying to choose between local anesthesia and regional anesthesia for your surgical procedure, you need to consider three practical things: how large an area needs to be numbed, how long you’ll need pain control, and what will help you feel most at ease during the procedure. 

Continue reading to get answers to these and more questions that will help you make the best choice for your treatment, including where to find the best anesthesiologists in San Jose.

Regional Anesthesia vs. Local Anesthesia: What’s the difference? 

Local anesthesia is the best way to numb a small area, usually a palm-sized area or less. It involves injecting numbing medicine directly where the work is being done, and you’re typically awake and alert the whole time. You will usually feel a brief sting, a burn, or pressure as the medicine is injected before the area numbs. Even with local anesthesia, you can still notice touch and movement, but any sharp pain should fade.

Regional anesthesia targets a larger area of the body. Instead of numbing one small spot, it numbs a cluster of nerves that carry pain signals from an entire region. This can include a spinal or epidural for the lower body or a peripheral nerve block for the arm, shoulder, knee, or foot. As it takes effect, people often report a warmth spreading, tingling, or a sensation of the target area falling asleep. With regional anesthesia, you can either stay awake or choose sedation that makes you drowsy and less aware of the sounds and activity in the room, depending on the procedure and what feels most comfortable for you.

How Long Do Local and Regional Anesthetics Last?

Local anesthetics last only a short time, usually an hour or two. This is why they are only used for minor or simple pain control. A regional nerve block, on the other hand, can keep an area numb for hours, and for up to a full day if additional medication is administered. 

As regional anesthesia wears off, the warm heaviness fades, tingling appears, and pain can increase quickly once the nerves wake up. That is why it helps to ask your team exactly when to start oral pain medicine, because starting too late can leave you chasing pain instead of staying ahead of it. 

Whether you have sedation or not, recovery from regional anesthesia takes a while. Plan for a ride home and take it easy for a couple of days. Many post-surgical care instructions recommend no driving and avoiding activities that require full attention for about 24 hours, since the medication can leave you foggy or slower to react even after you feel mostly fine. 

Risks and Side Effects of Local and Regional Anesthetics

Local anesthesia is considered very safe. The most common issues are short-lived, such as soreness, itching, or tenderness at the injection site. 

Regional anesthesia is also very safe, which is why it’s common for childbirth and many arm, leg, and lower-body procedures. The side effect people ask about most is a headache after a spinal or epidural. This can feel like deep pressure that worsens when you sit or stand. Typically, this side effect fades after a few days. More serious problems like infection, bleeding, or nerve injury can happen, but they are rare, especially when you choose a highly knowledgeable and experienced anesthesia team. 

How to Choose the Right Anesthetic for Your Procedure

Choosing the right treatment option starts with discussing your medical history and medications with your anesthesia provider. Medications such as blood thinners or anticoagulants may affect how anesthesia providers recommend certain regional anesthetics, such as epidurals, spinal anesthetics, or deeper nerve blocks. 

Local anesthetics are typically used for short procedures in a small, specific area, such as:

• Skin procedures, including mole or skin tag removal, biopsies, cyst or abscess drainage, and wound cleaning
• Stitches and wound repair 
• Dental work, including dental fillings, crowns, root canals, deep cleanings, and tooth extractions 
• Minor outpatient procedures like ingrown toenail treatment or small lump removals
• IV placement 
• Numbing before joint injections or trigger-point injections 

Regional anesthetics are typically used for procedures where a larger area needs to be numbed, such as:

• Childbirth and C-sections
• Hip, knee, ankle, or foot surgery
• Shoulder, arm, wrist, or hand surgery
• Hernia repairs 
• Post-op pain control
• Some outpatient orthopedic procedures
