Which gases are used in hospital to put people sleep?

In the context of medical procedures, two primary gases are commonly used to induce and maintain sleep or a state of unconsciousness:

1. Nitrous Oxide (N₂O), also known as laughing gas: This gas has been used for over 150 years in dentistry and various medical procedures. Nitrous oxide has analgesic and anxiolytic effects, which means it can relieve pain and anxiety. As a result, it is often used for short-term procedures such as dental work, minor surgeries, and childbirth. It is typically mixed with oxygen and inhaled through a mask.

2. Sevoflurane: Sevoflurane is an inhalational anesthetic agent used to induce and maintain general anesthesia during surgical procedures. It is commonly preferred for its rapid onset and recovery, along with its relatively reduced side effects compared to other inhalational anesthetics. Sevoflurane also provides muscle relaxation and suppresses the body's response to pain.

Both nitrous oxide and sevoflurane are carefully administered and monitored by medical professionals to ensure the patient's safety and well-being during medical procedures.
