Hypnosis can be a useful therapeutic adjunct to pharmacological analgesia or anaesthesia in obstetrics. However, it is rarely considered a primary anaesthetic technique and is seldom employed in the acute surgical setting. Few obstetricians and anaesthetists currently utilise this technique in their clinical practice. We present a case report of a 34‐year‐old woman who successfully underwent evacuation of a large vulval haematoma using the simple hypnosis technique of ‘believed‐in imagination’ as the principal anaesthetic technique with only minimal adjunctive pharmacological analgesia.
