Abstract
Dreaming under anaesthesia was investigated in a prospective study of 120 day case paediatric patients, aged 5-17 years, who underwent a variety of surgical procedures. Patients were anaesthetised using the 'Liverpool technique' of paediatric anaesthesia (nitrous oxide-oxygen-relaxant). No patient reported awareness, but 23 of 120 patients (19%) reported dreams. Analysis of the data revealed that the choice of muscle relaxant, (nondepolarising or depolarising) had a statistically significant effect on the incidence of dreaming (p less than 0.05). It is suggested that the technique of intermittent intravenous suxamethonium may result in increased muscle spindle discharge and cause cerebral arousal and an increased incidence of dreaming.
