Multiple exposures to post-natal anesthesia leave a long-term effect on behavior of the child   A primate animal model based study showed repeated exposure to an anesthetic agent in post-natal period results in a long term effect on child's behavioral pattern resulting in anxiety disorder. Approximately one million children under the age of four undergo surgery with general anesthesia, according to the U.S. Food and Drug Administration (FDA).

Few earlier birth-cohort studies on children have found an association between learning disability and multiple exposures to anesthesia in early life. Some research in animal models, mainly rodents, has shown that early anesthesia exposure causes cell death in the brain and cognitive impairments later in life. But the applicability of rodent studies to humans has been questioned on many grounds, majorly on the lack of correspondence of…
