Why the study?
Does exposure to a suggestion during deep surgical anaesthesia lead to memory recall under hypnosis one month later?
Does exposure to a suggestion during deep surgical anaesthesia lead to memory recall under hypnosis one month later?
Patients under deep surgical anaesthesia may retain subconscious memories of intraoperative events that can be recalled under hypnosis.
Answers are grounded in this paper and cite their sources.
May indicate subconscious recall during anaesthesia; leaves open clinical relevance without controlled trials.
Ten patients were exposed during deep surgical anaesthesia to a suggestion indicative of an anaesthetic crisis. One month later the patients were hypnotized and regressed to the operation. Four were able to reproduce the words spoken by the anaesthetist. Four became anxious and woke from hypnosis. Two did not reproduce the suggestion.
