Understanding Anesthesia Options for Surgery: Part I – General Anesthesia

When preparing for surgery, understanding the type of anesthesia you may receive can help you feel more at ease and confident about your procedure. This article, the first in a two-part series, focuses on the basics of general anesthesia, its benefits, downsides, and how it is administered. Part II will delve into regional anesthesia techniques, such as nerve blocks, and their role in modern surgical care.


What Is General Anesthesia?

General anesthesia is a medical technique used to keep you completely unconscious and free of pain during surgery. Many people think of it as involving intubation or breathing tubes, but the true definition is based on how your body responds to stimuli. Under general anesthesia, you will not react to painful or non-painful stimuli, ensuring that you stay comfortable and unaware throughout the procedure.

General anesthesia is versatile and can be tailored to your specific needs. It works by temporarily halting the brain’s ability to process and respond to pain signals, effectively putting your entire body into a state of deep rest. Unlike local or regional anesthesia, which numb specific parts of your body, general anesthesia affects your whole system.

Levels of Sedation and Anesthesia:

  • Light Sedation: You remain awake but feel relaxed, often used for minor procedures.
  • Moderate Sedation: You feel drowsy but can respond to touch or verbal cues.
  • Deep Sedation: You are nearly unconscious and may need help breathing.
  • General Anesthesia: You are fully unconscious, do not feel pain, and require close monitoring of vital functions by an anesthesiologist.

Comparison to Other Types of Anesthesia:

  • Local Anesthesia: Numbs a small area of the body for minor procedures.
  • Regional Anesthesia: Numbs a larger area, such as an arm or leg, often combined with sedation.
  • Sedation (Monitored Anesthesia Care): Keeps you deeply relaxed but conscious.

General anesthesia is typically used for complex or lengthy surgeries, such as shoulder replacements or arthroscopic procedures, where complete immobility and pain relief are essential.


Benefits of General Anesthesia

  1. Complete Comfort: You will be entirely unaware of the surgery, eliminating anxiety and discomfort.
  2. Pain-Free Experience: Prevents you from feeling any pain during the procedure.
  3. Precise Monitoring: Your vital signs and bodily functions are closely managed by your anesthesiology team.
  4. Adaptability: Works well for a wide variety of surgeries, including those requiring complex positioning.

Downsides of General Anesthesia

While general anesthesia is safe and commonly used, it is not without risks:

  • Common Side Effects: You might experience nausea, vomiting, sore throat, or drowsiness after waking up.
  • Cardiopulmonary Risks: Rarely, complications like lung or heart issues may occur.
  • Longer Recovery Time: General anesthesia can take more time to wear off compared to other types.
  • Rare Complications: These can include issues related to specific surgical positions, such as the beach chair position used in shoulder surgeries.

Combining general anesthesia with nerve blocks, which completely numb large portions of the body, can decrease the amount of general anesthesia necessary to keep a patient comfortable and decrease potential risks and complications. Nerve blocks will be discussed in more depth in Part II of this series.


How Is General Anesthesia Administered?

General anesthesia can be delivered in two main ways:

  • Inhalation: You breathe anesthetic gases through a mask or breathing tube.
  • Intravenous (IV) Medications: Drugs are injected into your vein to induce and maintain unconsciousness.

Airway Management During Surgery

To ensure you can breathe properly while under general anesthesia, your anesthesiologist may use:

  • Laryngeal Mask Airway (LMA): A device placed over your larynx, typically used for shorter surgeries.
  • Endotracheal Intubation: A tube inserted into your windpipe, which is often used for longer or more complex procedures to fully protect your airway.

My Preference: Combining Regional and General Anesthesia

In my practice, I prefer to use a combination of regional and general anesthesia for most of my surgeries. By adding a regional block, such as an interscalene nerve block, the amount of general anesthesia required is significantly reduced. This approach decreases many of the common side effects of general anesthesia, such as nausea, drowsiness, and prolonged recovery time, while providing excellent pain control during and after the procedure. The type of nerve blocks and medications administered will be covered in detail in the next blog post in this series. This balanced method ensures the best possible surgical experience for my patients.


Can Shoulder Surgery Be Done Without General Anesthesia?

For some patients, shoulder surgery can be performed without general anesthesia by using regional techniques like nerve blocks. With an interscalene nerve block, pain signals from the shoulder are effectively blocked, allowing you to remain comfortable throughout the procedure. In these cases, sedation can be used to help you stay relaxed and at ease without the need for full unconsciousness. However, one drawback of performing shoulder surgery under a regional block is that if there is an issue—whether it’s a medical complication or the procedure becomes too painful to tolerate without general anesthesia—it can be challenging to access the airway quickly to convert to general anesthesia. This is an important consideration to discuss with your surgical team when planning your procedure.


Summary

Understanding your anesthesia options can make a significant difference in how you feel before, during, and after surgery. General anesthesia provides complete comfort and immobility, making it ideal for complex procedures. In Part II of this series, we’ll explore the role of regional anesthesia, including its benefits and how it can complement general anesthesia for an optimized surgical experience. Your anesthesiologist and surgical team will work together to create a customized plan that ensures your safety and comfort.
