View clinical trials related to Claustrophobia.
Filter by:Claustrophobia is an irrational fear of restriction and suffocation. It is a specific phobia, according to DSM 5. Claustrophobic patients may fear that restriction of their limbs will hinder their ability to move quickly towards safety. MRI may trigger claustrophobia, because this diagnostic procedure involves a patient laying in a narrow tube. Premedication before MRI scan may occasionally reduce claustrophobia. Prospective observational crossover study of claustrophobic patients who are undergoing MRI scan. At alternate MRI scan sessions, each patient receives rotational premedication using Lorazepam 1mg; or Clonidine tablet 0.2mg; or combined Clonidine 0.2mg + Lorazepam 1mg. Patient will use Claustrophobia Questionnaire, a validated tool, to collect data on the days before and after each MRI scan. CLQ is a patient-administered tool used to assess claustrophobia. In addition, patient will use General Anxiety Disorder Questionnaire, a validated tool, to collect data on the days before and after each MRI scan. GAD-7 is a patient-administered tool that is used to assess anxiety.
The access to MRI examination is limited due to the duration of the acquisitions, the noise and the narrow patient space of the device. A child can, therefore, be anxious, less cooperative and move more during the acquisition, affecting the quality of the examination and the medical diagnosis. General anesthesia or sedation, may be considered to obtain diagnostic quality examinations. Our hypothesis is that a scenario as close as possible to reality to prepare children before the MR exam could reduce their anxiety, improve the quality of the exams and reduce its duration. The purpose of this study is to evaluate the effect of virtual reality on MRI exam preparation to reduce the anxiety of children (aged from 6 to 12 years) who are referred to their first MRI exam, as compared to the current practice.
This study is to determine the possibility of assessing the level of anxiety in MRI patients by means of the respiration rate (RR) and heart rate (HR) indicators acquired by a fiber-optic sensor system. The mean RR and/or HR values recorded at the beginning and the end of an MRI scanning will be referred to the State Trait Anxiety Inventory (STAI) scores completed before and after the MRI scanning, respectively.
