Abstract
BACKGROUND: Hypnosis sedation has recently been used for anesthesia in breast oncologic surgery. METHODS: Between January 2017 and October 2019, 284 patients from our Breast Clinic (Cliniques Universitaires Saint-Luc, Université Catholique de Louvain) and from the Jolimont Hospital were prospectively included in an interventional non-randomized study approved by our two local ethics committees and registered on clinicaltrials.gov (NCT03330117). Ninety-three consecutive patients underwent surgery while on general anesthesia (GA group). Ninety-two consecutive patients underwent surgery while on general anesthesia preceded by a hypnorelaxation session (GAVRH group). Ninety-five consecutive patients underwent surgery while exclusively on hypnosis sedation (HYPS group). Clinical parameters (pain score, anxiety and distress score) were measured on days 0, 1 and 8 for all patients. All evaluable patients underwent NLR (neutrophil-to-lymphocyte ratio) and CRP (C-reactive protein) dosage on days 0, 1 and 8. RESULTS: Pain scores and anxiety scores were statistically lower in the HYPS group on days 1 and 8, as was the duration of NSAID consumption. NLR and CRP values were significantly inferior on day 1 for all patients who benefited from hypnosis sedation. CONCLUSIONS: Some benefits of hypnosis sedation (reduction in postoperative pain, decrease in NSAID consumption) are correlated with a significant reduction in inflammatory parameters in the perioperative process.
