What Are the Differences Between General Anesthesia and Local With IV Sedation?

When considering plastic surgery, one of the most critical decisions patients face is the type of anesthesia they’ll receive during the procedure. Two common options are general anesthesia and local anesthesia with intravenous (IV) sedation. In this article, we explore the key differences between these two approaches to anesthesia.

Option 1: General Anesthesia

General anesthesia induces a temporary loss of consciousness. It involves administering medications through inhalation or intravenous injection to render the patient completely unconscious. This state ensures they are entirely unaware and unresponsive to the surgical procedure and any discomfort associated with it. Under general anesthesia, patients are closely monitored by an anesthesiologist throughout surgery to ensure their safety.


  • Ensures the patient remains unconscious throughout the procedure
  • Eliminates any potential discomfort or awareness
  • Induces muscle relaxation, ensuring optimal conditions for surgical precision
  • Ideal for lengthy and invasive surgeries, such as extensive breast explantation


  • Patients may experience grogginess and drowsiness upon waking up from anesthesia
  • Recovery time can be longer compared to other anesthesia options
  • Although rare, general anesthesia carries risks such as nausea, vomiting, and confusion
  • Requires careful monitoring to mitigate potential complications

Option 2: Local Anesthesia with IV Sedation

Local anesthesia with IV sedation, commonly known as twilight anesthesia, involves injecting numbing medication directly into the surgical site to block sensation. Additionally, intravenous sedatives are administered to induce a relaxed, semi-conscious state. Unlike general anesthesia, patients remain responsive but deeply relaxed throughout the procedure.


  • Patients undergoing local anesthesia with IV sedation tend to recover more quickly
  • Patients can usually resume normal activities sooner after the procedure
  • Lower risk of complications associated with general anesthesia, such as respiratory issues
  • Allows for the precise targeting of anesthesia while providing a comfortable experience


  • May not be suitable for extensive surgeries that require deeper levels of anesthesia (bowel resection, gallbladder)

Choosing the Right Anesthesia Option

The choice between general anesthesia and local anesthesia with IV sedation depends on various factors, including the type and duration of the surgical procedure, the patient’s medical history, and personal preferences. Here are some considerations to keep in mind:

  • Type of Procedure: Complex surgeries or those involving extensive tissue manipulation often require general anesthesia to ensure patient safety.
  • Patient Health: Patients with certain medical conditions, such as cardiovascular or respiratory issues, may not be ideal candidates for general anesthesia.
  • Personal Comfort Level: Some patients may feel more comfortable being fully unconscious during surgery, while others prefer to remain semi-conscious.

Both general and local anesthesia with IV sedation are valuable tools in plastic surgery, each offering distinct benefits. While general anesthesia offers complete unconsciousness and muscle relaxation, it comes with a longer recovery time and potential side effects. On the other hand, local anesthesia with IV sedation provides a quicker recovery and reduced risk but may not be suitable for all surgeries.

Ultimately, the decision should ultimately be made in consultation with your surgeon and anesthesiologist, who can assess your unique needs and recommend the most appropriate anesthesia option.
