Comparison of the Effect of the Laryngeal Mask on Pediatric Indirect Inguinal Hernia Operation to Mask Combined with Ketamine-sacral Anesthesia

Abstract：Objective:Comparison of effect of the laryngeal mask on pediatric indirect inguinal hernia operation anesthesia to mask combined with ketamine-sacral anesthesia.Methods:ASAⅠ-Ⅱ,40 patients of 2-6 years age undergoing hernia ligation,were randomly equally divided into the laryngeal mask ventilation group (L group) and mask ventilation group (M group),Two groups of children room after intramuscular injection of ketamine 5 mg/kg,after 2 min sacral block,after successful puncture 1%lidocaine 8~10 mg/kg sacral canal injection,inserting the laryngeal mask airway in L group,at the same,M group in children with buckle hood,spontaneous breathing,oxygen retention of 2~3 L/min.Record before skin incision (T1),skin incision after 1min (T2),10 min (T3),at the end of the operation (T4),sober deoxidization of (T5) MAP,HR,SpO2<95%were observed intraoperatively,beside with intraoperative have no body movement,aspiration,postoperative sore throat complications.Results:In two groups of operation on children,MAP,HR had no significant difference (P>0.05), L group in operation on children with SpO2<95%were significantly less than M group(P<0.05),two groups had no body movement,intraoperative complications such as aspiration(P>0.05 ) in L group,but postoperative sore throat had a greatly higher incidence of M group(P<0.05).Conclusion:In pediatric hernia operation, two methods are safe and effective,and in the LMA combined with ketamine-sacral anesthesia,it can be better sustaining intraoperative airway patency,avoiding of hypoxia,guaranting the quality of anesthesia,at the same shall be attention to the throat sore of postoperation.
