Primary Objectives:

• To measure and record patients' pain levels before, during, and after standard procedures performed in IR.
• To compare different procedures to respective pain levels and patient satisfaction (as determined by questionnaire).

During the IR procedure, nurses commonly ask patients to tell them what their pain level is on a 0-10 scale. For those who participate in the study, these numbers will be used to calculate average pain levels. Study participants will be asked to complete the same 0-10 pain scale during the recovery period until time of discharge or admission to the hospital. According to standard criteria when giving conscious sedation, patients will remain in a communicable state throughout the procedure and during the recovery period prior to discharge, and thus, will be able to express a pain level during these times. The same questionnaire will be given for seven days after the procedure, which will be completed on a self-addressed, stamped postcard to be mailed back to UTMDACC. The last postcard will have a couple of questions about patient satisfaction. Once the last postcard is mailed in, the patient's participation in the study is over. Each questionnaire should take less than 5 minutes to complete.

This is an investigational study. About 374 patients will take part in this study. All will be enrolled at UTMDACC.
