Early Mobilisation and Relational Touch Practice on Intubated Patients of Intensive Care Unit

41.3% of patients hospitalized in intensive care express feeling anxiety when they are systematically questioned. Ventilatory weaning is one of the moments of anxiety for the patient. While being conscious he must tolerate invasive ventilation. The early mobilization of patients in intensive care must be started early, within 24-48 hours, after the patient wakes up. Early mobilization is part of the weaning process from invasive mechanical ventilation in intensive care. It is recommended to reduce it to use relaxation therapies. Several studies have assessed the impact of relational touch in conscious or unconscious patients in intensive care. The SRLF consensus conference in 2010 recommends the use of massage for anxiolytic purposes. This study aims to assess the impact of relational touch versus standard care on anxiety during the first bedside session, in intubated intensive care patients ventilated for at least 48 hours and presenting with RASS (Richmond agitation sedation scale). ) from 0 to -1. The study will aussi assess the impact of relational touch versus standard care on the following patient parameters: * Evaluation of caregiver anxiety with the Spielberger inventory before and after the session * Increasing the duration of the bedside session; * Variations in pain, assessed by the Behavioral Pain Scale (BPS) at the end of the session; * The level of agitation/vigilance at the beginning and at the end of the session with the Richmond agitation-sedation scale (RASS); * Induced variations in blood pressure; * Induced variations in oxygen saturation; * The variations induced on the respiratory rate; * The variations induced on the heart rate; * The need to prescribe psychotropic drugs on the day of the first bedside; * Reduction in the number of days of invasive mechanical ventilation between the first bedside session and discharge from intensive care unit (maximum D28 after the first bedside session).
