Many patients undergoing flexible bronchoscopy (FB) experience anxiety and discomfort during the procedure. The investigators want to evaluate whether an additional Lorazepam premedication would improve patient satisfaction for FB.

The enrolled patients are randomized to either the control or Lorazepam groups according to a random sample chart of numbers. The patients complete questionnaires about baseline anxiety level and satisfaction for FB within 24 hours after the FB.

Inclusion Criteria:

• Adult patients (aged 18 years or older) admitted to the Respiratory Department

Exclusion Criteria:

• outpatient procedures
• therapeutic bronchoscopy
• expected operation or discharge within 24 hours after the FB
• sedative premedication
