A Comparision Of Sacral Canal Block Combined With Intravenous Anaesthesia And Sevoflurane Anaesthesia With LMA In Children Undergoing Surgery

Objective To compare the advantages and disadvantages of sacral block combined with intravenous anesthesia and sevoflurane with LMA in children undergoing surgery.Method All the cases are from Yanbian university affiliated hospital, selective operation (hernia,cryptorchidism,varicocele,hydrocele of the testis,hypospadias,appendictis) 120 cases 1-5 years old, ASAⅠ-Ⅱweigh 10-20 kg, normal intelligence and language development. Their operation were enforced a.m, about 1 hour. Elimination standard:sever heart lung liver kidney disease, coagulation disorders, obesity, history of asthma,recent respiratory infections, airway hyperreactivity, suspected difficult airways, gastroesophageal reflux disease. The patients are divided into three groups randomly, each group with 40 cases; After open vein circuit, every group intravenous ketamine 2mg/kg, midazolam0.06mg/kg, propofol 2mg/kg, groupⅠimplement sacral tube block, lidocaine 5-8mg/kg, maximaldoselOmg/kg; groupⅡinsert LMA, inhalation2-3% sevoflurance, groupⅢimplement sacral tube block, insert LMA, inhalation 2-3% sevoflurance, during the operation when the patients of three groups appear physical activity, superaddition ketamine lmg/kg,MAP,HR,SpO2 were measured before anesthesia(TO), before cut skin(T1), cut skin instantly(T2), after cut skin 5 minutes(T3), after cut skin 15 minutes(T4), after cut skin 25 minutes(T5), the end of operation(T6), total dose of Ketamine, side effects and the residence time in PACU were recorded.Result There were no statistical significances among three groups about children's age, sex ratio, weight, operation time; there were no statistical significances among three groups about children's MAP,HR,SpO2 at every time point; the residence time in PACU and total dose of Ketamine of groupⅠwere significantly more compared with groupⅡ,Ⅲ, there were statistical significances, the incidence of postoperative restless in groupⅡwas significantly higher compared with groupⅠ,Ⅲ, there were statistical significances, there were no statistical significances among three groups about the incidence of physical activity, nausea and vomiting, laryngospasm etc adverse reactions.Conclusion 1,sacral canal block combined with intravenous anesthesia make waking time longer, but can obviously decrease the incidence of postoperative restless.2,sevoflurane anesthesia with LMA can shorten waking time, but have a high incidence of postoperative restless.3,sacral canal block combined with intravenous anesthesia joint sevoflurane anesthesia with LMA can not only shorten waking time, but also decrease the incidence of postoperative restless. Worth extending.
