Hypnosis Sedation Used in Breast Oncologic Surgery Significantly Decreases Perioperative Inflammatory Reaction.

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.
