Volatile halogenated gases and nitrous oxide used as part of a balanced general anesthetic may contribute to global warming. By avoiding volatile inhalational agent use, regional anesthesia may reduce greenhouse gas emissions and help prevent global warming. This article presents a theoretical calculation of the potential benefits and a real-life example of how much regional anesthesia may reduce greenhouse gas emissions.

-- While regional anaesthetics numb a certain part of the body, general anaesthetics make patients totally unconscious for what tend to be more serious procedures.

-- But unlike regional anaesthetics, generals use volatile and environmentally-unfriendly halogenated agents, such as desflurane, or nitrous oxide.

-- At one New York hospital last year, just 4 percent of hip and knee replacement procedures were done under general anaesthetic, compared to a nationwide average of 75 percent.

-- This switch prevented carbon emissions equivalent to thousands of pounds of coal burnt or more than three million smartphones charged, US researchers say.

-- Most regional anaesthesia uses a local nerve-blocking agent along with intravenous sedatives, eliminating the use of halogenated gases.

-- Some of the gases uses to induce general anaesthesia are thousands of times more potent than our best-known greenhouse gas, carbon dioxide.

-- Very little, less than 5 percent of the volatile halogenated gases used during general anesthesia is metabolised by the patient.

However, Not all surgical procedures are suitable to being performed under regional anesthesia alone, such as brain surgeries, the researchers admit. The decision to use a specific anesthetic method should also primarily be based on the individual patient and their condition.
