This is a randomized clinical trial of deep procedural sedation with propofol with and without supplemental alfentanil. Patients will be assessed for total and fractionated serum catecholamines before and after the procedure in addition to usual procedural sedation outcomes parameters to assess the adrenergic effect of propofol sedation without supplemental opioid.
