Objective - Implant placement Essure (TM) sterilization procedure for women were performed under hypnosedation (HYP) and compared to the operative anxiety and analgesia of 12 patients operated-on under general anesthesia (GA)Study design - Prospective and comparative group studyPatients and methods - Two groups of twelve patients were matched and compared based on the choice of anesthetic technique hypnotics (HYP) with possible additional sedation by propofol and remifentanil or GA involving propofol sevoflurane and remifentanil The assessment of anxiety and pain based on a visual analogy scale (0-10) and use of analgesics were studied in the recovery room and at discharge of hospital The statistical analysis relies on nonparametric tests for paired data (Wilcoxon test)Results - All patients were operated The two groups are statistically comparable The preoperative anxiety before premedication is lower in the HYP group (p < 0 05) No conversion to general anaesthesia is necessary in the HYP group but five patients were using sedatives drugs but doses are very low compared to general anaesthesia The analgesic consumption was equivalent in both groupsConclusion - We conclude that hypnosedation is a valuable alternative to traditional anesthetic techniques for ambulatory Essure (TM) implant The use of hypnotic tool is an interesting alternative for the management of patients during invasive medical procedures or surgical providing psychological benefits to the patient (C) 2010 Published by Elsevier Masson SAS
