About

Emergence agitation (EA) is common phenomenon in pediatric patients undergoing general anesthesia by inhalation agents. The incidence of EA was reported to range from 18% to 80%. Sevoflurane now is the inhalational anesthetic agent of choice for pediatrics, Different strategies have been suggested to decrease the incidence and severity of EA. No gold standard technique for treating EA after sevoflurane anesthesia is currently available. The main question is can caudal dexmedetomidine be used for this purpose?

Full description

The purpose of this prospective comparative randomized clinical study will be to compare the effects of caudal dexmedetomidine on EA in children undergoing lower abdominal operations under general sevoflurane anesthesia. In addition, characteristics of anesthesia recovery and incidence of adverse effects will be compare. A total of (48) children aged 1-5 years old, The American society of Anesthesiologists (ASA) physical status classification system between I-II of both sex who will be enrolled from April 2016 to April 2017 undergoing for lower abdominal surgeries will be included in the study. Patients will be randomized by computer-generated random numbers in a double blinded fashion to get enrolled into 2 equal groups: Group BD patients (n = 24) will be received single dose caudal epidural analgesia using dexmedetomidine with bupivacaine, whereas Group B patients (n = 24) will be received single dose caudal epidural analgesia with bupivacaine only. The dexmedetomidine used for this study will be prepared in a 1 ml syringe wrapped in aluminum foil by an investigator who will not be involved in the anesthesia process and another 1 ml syringe filled with saline will be prepared too.
