Anaesthesia
-
This study investigated the effects of pre-procedural anxiety (assessed using the Beck Anxiety Inventory) on sedative requirements in 135 patients undergoing sedation for colonoscopy. Deep sedation was defined as loss of consciousness and no response to colonoscopy, and was achieved by target-controlled infusion of propofol. ⋯ There was no statistical difference in the characteristics of recovery among patients with different levels of anxiety. In conclusion, in patients receiving deep sedation for colonoscopies, the level of pre-procedural anxiety did not relate to the sedative requirement or post-procedural recovery characteristics.
