Sevoflurane Side Effects

In the world of anesthesia, sevoflurane is a commonly used inhalation agent. It plays a crucial role in making surgical procedures more comfortable for patients. However, like any medication, sevoflurane is not without its side effects. In this comprehensive guide, we will delve into the various aspects of sevoflurane side effects, providing you with valuable insights and information.

Sevoflurane Side Effects


Sevoflurane, often referred to simply as “sevo,” is a volatile inhalation anesthetic widely used in medical practice. Its popularity stems from its rapid onset and offset of action, making it an excellent choice for maintaining anesthesia during surgery. However, like all medications, sevoflurane is associated with various side effects that both patients and healthcare professionals should be aware of.

Sevoflurane Side Effects

Let’s take a closer look at the potential side effects of sevoflurane

Gastrointestinal Effects

Sevoflurane administration can occasionally lead to gastrointestinal disturbances, such as nausea and vomiting. These effects are more common in susceptible individuals, and your anesthesiologist will take measures to minimize them.

Respiratory Complications

Respiratory side effects, including coughing and bronchial irritation, may occur after inhaling sevoflurane. It’s crucial for your anesthesia team to monitor your respiratory function closely during the procedure to manage any complications promptly.

Cardiovascular Concerns

Sevoflurane can affect the cardiovascular system, potentially causing a decrease in blood pressure and heart rate. An experienced anesthesiologist will carefully titrate the sevoflurane dosage to maintain stable cardiovascular function.

Central Nervous System Effects

Sevoflurane is known for its rapid induction and emergence from anesthesia, contributing to a smoother recovery process. However, some patients may experience postoperative confusion or agitation, which typically resolves quickly.

Allergic Reactions

While rare, allergic reactions to sevoflurane can occur. Signs of an allergic response include skin rashes, difficulty breathing, and swelling. Immediate medical attention is crucial if you suspect an allergy to sevoflurane.

Hepatic Effects

In some cases, sevoflurane has been associated with temporary liver function abnormalities. These effects are usually transient and resolve on their own.

Renal Function

Sevoflurane can impact kidney function, potentially leading to changes in urine output. Monitoring your renal function during surgery is essential for managing any issues that may arise.

Postoperative Shivering

After surgery, some patients may experience shivering as a side effect of sevoflurane. Your healthcare team will take measures to keep you warm and comfortable during the recovery period.
