Brief Summary

Colonoscopy is an outpatient procedure performed frequently as a screening test for diagnosis and treatment of a wide range of gastrointestinal problems. It is often viewed as an invasive procedure with the potential for embarrassment, discomfort, and worry. Such fears can result in anxiety that may decrease the tolerance and cooperation of the patient, limit the success of the procedure, and increase the likelihood of complications. Therefore, colonoscopy is frequently performed under sedation. The anxiety level of the patient before the procedure may increase the requirement for sedation. It is important for the anesthesiologist to predict the effective dosages of sedation before the procedure to ensure rapid and comfortable sedation as well as prompt recovery and discharge of the patient. This prospective cohort study is planned to evaluate the effects of pre-procedural anxiety level on the dose of propofol needed for patient and surgeon satisfaction during colonoscopy.

Outcome Measures

Primary Outcomes (1)

  • To evaluate the effects of pre-procedural anxiety level on the dose of propofol needed for sedation during the procedure.

    The sedation protocol applied in this study is our routin approach for all outpatient colonoscopies and endoscopies. All patients are informed about the procedures and monitorized (EKG, spO2, Bispectral index, blood pressure). After that, the sedation protocol is started and once the appropriate BIS value is reached the procedure is started. For this study all patients were asked to complete the STAI scores to evaluate the pre-procedural anxiety. This is not an intervention but an evaluation of the patients' anxiety. The primary outcome measure is to evaluate the dose of propofol used in each patient and to find out if there is a correlation between the pre-procedural anxiety and the dose of propofol.

    The anxiety of all patients is evaluated at the day of the procedure. The procedure is then performed under sedation. Once the procedure is ended and all patients are fully awake, study data are collected and patients are discharged home.

Study Arms (1)

Sedated colonoscopy

Planned colonoscopies for screening under propofol sedation titrated to reach a bispectal index value of 60. Anxiety levels are assessed before the procedure with State-Trait Anxiety Inventory Scores.

Other: State-Trait Anxiety Inventory Scores

Interventions

Patients are evaluated before the procedure with State-Trait Anxiety Inventory scores to determine the anxiety level.
