When she was readmitted because of symptoms arising from her experience, two weeks after the operation, she gave an account of her experience to a hospital doctor, who took the matter up with the hospital’s senior anaesthetist. The basis of the plaintiffs case was: she was not rendered unconscious to the stage intended by the anaesthetist and remained aware until the operation began; this failure was caused by incorrect administration of anaesthetic and a failure to check that it had worked; this failure was negligence by the anaesthetist and caused the plaintiff to suffer recurrent anxiety attacks.

Claim for Negligent Induction of AnaesthesiaDismissed, but no Costs for Defendant Health

AuthorityTHE plaintiff, then 28, was admitted to hospital for a

hysterectomy, performed on July 12, 1976. She alleged she wasinsufficiently anaesthetised, and, though paralysed and unable tocommunicate, she remained "aware" until the moment of theincision. She suffered "conversion hysteria" subsequently. She didnot complain of the experience until she was discharged. When shewas readmitted because of symptoms arising from her experience,two weeks after the operation, she gave an account of her experienceto a hospital doctor, who took the matter up with the hospital’ssenior anaesthetist.The basis of the plaintiffs case was: she was not rendered

unconscious to the stage intended by the anaesthetist and remainedaware until the operation began; this failure was caused by incorrectadministration of anaesthetic and a failure to check that it had
