Although the Narcosis Room at The Royal Waterloo Hospital is the best documented of the units in the UK, Narcosis was given at other NHS hospitals. William Sargant relied heavily on the nursing skills of St Thomas’ Nightingale Nurses to keep too many of his patients from dying but in other units there was far less nursing expertise and so patients given Narcosis in provincial hospitals, mainly concentrated in the South of England, were potentially in greater danger whilst undergoing treatment. No one knows how many, if any, patients died in other UK units and the limiting factor was probably that Narcosis was given for a week or two at the most, simply because their wasn’t adequate nursing care for longer courses of treatment. Patients in these smaller units were often treated in a curtained off corner of a larger ward and there are upsetting stories of Narcosis patients being an object of curiosity of other patients and their visitors. Most of these units were run by psychiatrists who had trained at St Thomas’ and who carried Dr Sargant’s pernicious influence with them. St Thomas’ Hospital bears the responsibility of having allowed Narcosis/DST to be taught to a generation of psychiatrists, anaesthetists and nurses and by doing so allowing this abusive and brutal treatment to be perpetuated in the NHS.
