Psychomotor agitation in somatic units is a medical and psychiatric emergency requiring rapid intervention by the team in charge of the patient and the liaison psychiatrist. Verbal de-escalation is attempted throughout the treatment. Securing the surroundings is needed to protect both the patient and the team. The etiology of the agitation, somatic and/or psychiatric, should be investigated to allow the administration of an adequate treatment. Antipsychotics and benzodiazepines are often recommended. Physical restraint measures can be applied as a last resort if necessary. The continuation of care is decided jointly between the team in charge and the liaison psychiatrist. An intervention protocol has been drawn up by the HUG liaison psychiatry team.
