“…In an effort to minimize the anxiety symptoms of children undergoing surgery and familiarize them with the procedures to enhance their coping skills, healthcare professionals have developed preoperative preparation programs (O'Byrne, Peterson, & Saldana, 1997;Rice, Glasper, Keeton, & Spargo, 2008) and investigated the benefits of some interventions, such as the presence of a family member during the induction of anesthesia (McCann & Kain, 2001;Shirley, et al, 1998;Wollin, Plummer, Owen, Hawkins, & Materazzo, 2003), educational videos (Cassady, Wysocki, Miller, Cancel, & Izenberg, 1999), books (Felder-Puig, et al, 2003), and the use of several distracters such as music (Augustin & Hains, 1996;Heiser, Chiles, Fudge, & Gray, 1997;Kain, et al, 2004), video games (Patel, et al, 2006), and toys (Golden, et al, 2006). Based on the assumption that humor is associated with the well-being of patients (Bennett & Lengacher, 2006a, 2006bMartin, 2001;Stuber, et al, 2007), there has been an increase in interventions provided by "clown doctors" in pediatric settings (Koller & Gryski, 2008).…”
