Cliaical observation of remifentanil and ketamine combined with sevoflurane applied in pediatric surgery

Objective To explore the clinical effect of remifentanil and ketamine with sevoflurane in pediatric surgery. Methods 80 cases of ASAⅠ～Ⅱ grade line surgery in children, were randomly divided into remifentanil group(A group) and the ketamine group(B group). Intramuscular midazolam 0.3mg/kg basic anesthesia catheter later. A group 2min before skin incision to give 0. 5μg/kg remifentanil infusion pump micro pump remifentanil 30μg(kg/h) add sevoflurane inhalation 3MAC until surgery. B group 2min before skin incision 2mg/kg ketamine infusion then pump ketamine 3mg(kg/h) add sevoflurane inhalation 3MAC until surgery; Record separately the two groups before skin incision in children with 2 min(T0) ,atskin incision(T1),after skin incision 15min(T2) ,when surgery (T3) in children with the mean arterial pressure (MAP),heart rate(HR),respiratory frequency(R)and oxygen saturation (SpO2) ,and record the total number of children with secretions (sputum volume) , awake time and the availability of laryngeal spasm,restlessness,nausea, vomiting and other adverse reactions. Results A group sputum volume was less than B group(P＜0.01) and A Group awake time was shorter than B Group(P＜0.01) ;Two groups of patients R infants had no inter-group differences(P＞0.05) ,two groups of children during quiet sleep,analgesic perfect, no significant respiratory depression,no laryngeal spasm,restlessness and nausea,vomiting and other adverse reactions. Conclusion Remifentanil composite Sevoflurane for surgery in children than ketamine was more stable during the cycle, secretions less quickly after waking up was a safe and reliable method of anesthesia.
