islamabad-Like other parts of the globe, World Anaesthesia Day was also observed in Pakistan on Sunday to create awareness about the importance of the day.

Several private and public hospitals and other medical institutes   arranged a number of activities, including conferences, seminars and other events to mark the day.

Anesthesia Day commemorates the first successful demonstration of ether anesthesia on October 16, 1846. This ranks as one of the most significant events in the history of medicine, which took place at the Massachusetts General Hospital, home of the Harvard School of Medicine.  The discovery made it possible for patients to obtain the benefits of surgical treatment without the pain associated with an operation.

The date (16 October) is now globally recognised as World Anaesthesia Day in respect of the importance of this event.

Discovery of anaesthetic allowed the further development of painless surgical treatment. Nowadays anaesthetists use different types of anaesthesia - general, sedation and regional.    General anaesthesia suppresses activity in the central nervous system, resulting in unconsciousness and total lack of sensation.

Regional anaesthesia renders a larger area of body insensate and sedation reduces irritability, which is generally used to facilitate a medical procedure or diagnostic procedure.
