ABSTRACT
BACKGROUND: Recent reviews support that hypnosis has great potential for reducing pain and anxiety during mini-invasive surgery. Here, we assessed the feasibility of hypnotic induction session as adjunct therapy in conscious sedation for venous access device implantation. Primary outcomes were safety and patient satisfaction. METHODS: Thirty consecutive women with breast cancer were proposed adjunct of hypnosis before implantation under conscious sedation (midazolam: 0.5 mg ± bolus of Ketamin: 5 mg on demand) indicated for chemotherapy. Self-hypnosis was programmed and guided by one of two trained anesthesiologists. Implantation was performed by one of two experimented surgeons. It consisted of blind subclavian implantation of Braun ST 305 devices using a percutaneous technique adapted from Selinger's procedure. Clinical data were prospectively collected and retrospectively analyzed. A comprehensive custom-made questionnaire recorded patient satisfaction. RESULTS: In all, 30/30 patients consented to the procedure. The median age was 54 years (range: 35-77 years). The primary procedure was successful in 29/30. One case was converted into internal jugular vein access after a first attempt. Median length time of the implantation procedure in the operative room was 20 min (range: 10-60 min). Median length time in the recovery room preceding home discharge was 65 min (range: 15-185 min). None of the patients suffered complications. The satisfaction rate was ≥90%, 27/30 patients would get hypnosis in case of reimplantation if necessary and 27/30 would recommend this procedure to others. CONCLUSION: Hypnosis under conscious sedation appears feasible and safe for port implantation under conscious sedation in cancer patients. Further studies would determine the exact value of hypnosis effectiveness.
