“…Specifically, the pain experienced by pediatric patients is routinely undertreated as children are not usually effectively medicated, and the pain levels that pediatric patients experience during hospitalization is often not adequately assessed and managed by nurses and hospital management (Kortesluoma, Nikkonen, & Serlo, 2008;Mathews, 2011;Twycross & Collins, 2013). Pediatric pain-management practices continue to fall short of the ideal (Shrestha-Ranjit & Manias, 2010;Twycross, Finley, & Latimer, 2013), with hospitalized children experiencing moderate to severe unrelieved pain postoperatively (Fortier, Chou, Maurer, & Kain, 2011;Shrestha-Ranjit & Manias, 2010;Taylor, Boyer, & Campbell, 2008). Pediatric patients with having postoperative pain are usually to experience difficulty coughing, deep breathing and mobilitation, thereby uncontrolled postoperative pain in children may increase postoperative complications, hospital stays and costs (Payakkaraung et al, 2010;Taddio et al, 2009;Twycross, 2009).…”
