目的探讨采用喉罩行全身麻醉且术前雾化吸入布地奈德对小儿麻醉恢复期呼吸系统不良事件发生率的影响。方法 2012年12月-2014年2月择期行腹股沟疝修补术的患儿100例,随机分为2组,每组50例。A组采用喉罩行全身麻醉;B组术前雾化吸入布地奈德,然后采用喉罩全身麻醉。观察患儿各种常见呼吸系统不良事件:术后喉痉挛发生程度及概率,麻醉恢复室停留时间及痰液量,术后患儿声嘶、语调改变发生率,术后呼吸道感染发生率。结果术中、术后A组与B组分别发生喉痉挛12例(24%)、3例(6%),术后发生声嘶、说话语调改变32例(72%)、9例(18%),发生呼吸道感染7例(14%)、1例(2%),组间差异均有统计学意义(P<0.05)。结论喉罩联合术前应用布地奈德雾化吸入能明显降低小儿麻醉恢复期呼吸系统不良事件发生率。
Objective To investigate the effect of laryngeal mask general anesthesia and preoperative inhalation of budesonide on the incidence of adverse respiratory events during convalescent anesthesia in children. Methods From December 2012 to February 2014, 100 children undergoing inguinal hernia repair were randomly divided into 2 groups (50 in each group). Group A received general anesthesia with laryngeal mask; group B received inhalation of budesonide preoperatively, followed by general anesthesia with laryngeal mask. A variety of common adverse respiratory events were observed in children with postoperative laryngeal spasm and the probability of occurrence of anesthesia recovery room residence time and sputum volume, postoperative children hoarseness, intonation change, postoperative respiratory infection incidence. Results There were 12 cases (24%) and 3 cases (6%) of laryngospasm after operation in group A and group B respectively. There were 32 cases (72%) and 9 cases (18% ), Respiratory infection occurred in 7 cases (14%), 1 case (2%), the differences were statistically significant (P <0.05). Conclusion The laryngeal mask combined with preoperative budesonide inhalation can significantly reduce the incidence of adverse respiratory events during convalescent anesthesia.
