RESUMO
Sedation is often justified in patients requiring colonoscopy. We investigated the potential usefulness of hypnotic relaxation in 13 women and 11 men (median age, 43 years; range, 22-67) for whom other forms of anesthesia were not available. Hypnotic relaxation resulted in moderate or deep sedation in 12 patients (nine women; p < 0.05). In the patients in whom hypnosis was successful, pain was less intense than in patients in whom hypnosis was unsuccessful (p < 0.001). In addition, all colonoscopies were completed in the successful group, versus 50% in the unsuccessful group (p < 0.05). The patients in the successful group all agreed to another examination under the same conditions, whereas only 2% in the unsuccessful group agreed (p < 0.001). Our study suggests that, in a subgroup of hypnotizable patients, hypnotic relaxation may be a safe alternative to drug sedation and merits further study.
