Postoperative emergence delirium develops in 12% to 18% of all children undergoing general anesthesia for surgery. This post-anesthetic phenomenon changes cognitive and psychomotor behavior, and puts pediatric patients and health care personnel at risk of injury. A newer drug, dexmedetomidine, is a selective alpha-2 agonist, which works in the brain and spinal cord that has sedative, analgesic and anxiolytic properties. Dexmedetomidine also has the ability to lower the overall anesthetic requirements by reducing sympathetic outflow in response to painful surgical stimulation. In current literature, there is not a systematic review that compares the effectiveness of preoperative intranasal dexmedetomidine administration against oral midazolam for the prevention of emergence delirium.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>The objective of this review was to identify the effectiveness of preoperative intranasal dexmedetomidine compared to oral midazolam for the prevention of emergence delirium in the pediatric patient undergoing general anesthesia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Inclusion criteria Types of participants<\/jats:title>\n                    <jats:p>This review considered studies that included pediatric patients aged three to seven years, with an American Society of Anesthesiologists (ASA) classification of I or II, and undergoing general anesthesia for elective\/ambulatory surgery.
