Abstract
Objective: To evaluate the implementation of a daily practice using cardiac coherence in patients with peritoneal carcinosis who underwent surgery. Materials and methods: Open, single-centre, controlled, randomized, and non-comparative phase II study, including 20 control patients versus 40 patients trained with biofeedback to use a breathing guide that will record their autonomous practice at home. Expected results: Successful adhesion of this nonpharmacological intervention before and after surgery, which may characterize parameters in favor of its implementation and evaluation of its impact on anxiety. Perspectives: Efficacy should then be assessed to transfer this supportive care to other patients.Perspectives: Efficacy should then be assessed to transfer this supportive care to other patients.
