A survey of more than 3 million patients who have been under anaesthetic in the UK and Ireland, has provided new insight into the

traumatic experiences of those who have woken up during surgery.

According to the research, led by Oxford University Hospitals in the UK, the phenomenon, known as “anaesthesia awareness” is rare but for smaller anaesthesia procedures, such as emergency C-sections, the risk is much higher at one in 670. Anaesthesia awareness was also more common among patients who had received paralytics – substances that block the nerves from stimulating muscles.

The patients in the survey who had woken up during surgery described experiencing a range of sensations, including choking, paralysis, pain, hallucinations, and near-death experiences.

The study found that paralysis was the most distressing part of the event – more so than the pain.

“Paralysis is terrifying and has never been experienced by most people,” Jaideep Pandit, a consultant anaesthetist who led the study, told CNN.

I would think that it would feel like hours. But with these studies one can only hope that they make a difference.
