About this study

Official title: Clonidine and Lorazepam Premedication for Claustrophobic Patients During MRI Scan

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.

Read the detailed description

Claustrophobia is an irrational fear of constraint, restriction, immobility, smothering and suffocation. Claustrophobia is a specific phobia, according to the Diagnostic and Statistical Manual 5 (DSM 5). The disorder affects 5% of the general population. Claustrophobic patients may fear that the restriction of their limbs will hinder their ability to move quickly towards perceived safety. Magnetic resonance imaging (MRI) may trigger claustrophobia, because this diagnostic procedure involves a patient staying immobile in a narrow and noisy tube. Anxiolytic premedication before MRI scan, using Lorazepam, may occasionally help to reduce claustrophobia.

This is a prospective observational crossover study of claustrophobic adult patients who are undergoing MRI scan as part of chronic pain management. 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.

The patient will use the Claustrophobia Questionnaire (CLQ), a special validated tool, to collect data on the days before and after each MRI scan. The CLQ is a patient-administered tool that is used to record the severity and presence of claustrophobia symptoms, on a measurement range of 0 to 104. A change in the CLQ scores by 12-points is considered significant. In addition, the patient will use the General Anxiety Disorder Questionnaire (GAD-7), a special validated tool, to collect data on the days before and after each MRI scan. The GAD-7 is a patient-administered tool that is used to record the severity and presence of anxiety symptoms, on a measurement range of 0 to 21. A change in the GAD-7 scores by 3-points is considered significant.

Data analyzed with IBM® SPSS® Statistics 25 (IBM Corp, Armonk, NY); using Student's t-test, ANOVA, Pearson Chi-square test, and regression analysis. P-value <0.05 is considered significant.
