Hollywood has long popularized the idea of a fast-acting 'sleeping gas' that instantly incapacitates victims. In reality, the concept of a universally effective, safe, and quickly deployable "sleeping gas" is fiction. Medical science instead uses carefully controlled inhaled anesthetics, so what is sleeping gas called in the real world?

While several historical and modern agents fit the description, the highly fluorinated methyl isopropyl ether known as sevoflurane is a primary example of a sweet-smelling product having anesthetic use. It is widely used in contemporary medicine for inducing and maintaining general anesthesia, prized for its low pungency which allows for a smooth induction, particularly in pediatric patients.

According to the American Society of Anesthesiologists, over 40 million anesthetics are administered each year in the United States. A critical step in many procedures is the induction of anesthesia, which refers to the transition from consciousness to an unconscious state.

Over 300 million surgical procedures requiring general anesthesia are performed annually worldwide. The question, 'What is the best drug for general anesthesia?', does not have a single answer, as the ideal agent is chosen based on a patient's individual needs, the type of surgery, and other specific factors.

Intraoperative hypotension is a common event, with some studies indicating it affects up to 88% of surgical patients [1.7.2, 1.7.3]. Understanding **what anesthetic drugs cause hypotension** is critical for anesthesiologists to maintain patient stability and prevent adverse outcomes associated with low blood pressure during surgery [1.7.1].

When administered intravenously, general anesthesia can induce unconsciousness in less than 30 seconds. This rapid onset is a defining feature, and understanding **how quickly do you fall asleep after anesthesia?** depends heavily on the specific drugs used and the patient's individual health profile.

An estimated 30 million people undergo general anesthesia annually in the US, highlighting the importance of understanding anesthetic safety profiles. Determining **which anesthetic is the least toxic** is not a simple question, as the safest choice depends heavily on the specific procedure, the patient's health status, and the type of anesthesia required. The concept of 'least toxic' is highly context-dependent, necessitating a careful balance of efficacy and risk by the anesthesiologist.

The risk of dying from general anesthesia is incredibly low, estimated to be about 1 in 100,000 to 200,000 cases for healthy patients [1.9.1, 1.9.5]. But **what do anesthesiologists use to put you to sleep** so safely? The answer is a sophisticated combination of drugs tailored to each individual.

The notion of anesthesia having a single, distinct odor is a common misconception, as the smell depends on the specific medication used. So, what does anesthesia smell like? The answer varies greatly depending on whether inhaled or intravenous agents are being administered.
