目的探讨喉罩在小儿先天性心脏病介入治疗麻醉中的优越性。方法选择先天性心脏病介入治疗患儿60例,随机分为喉罩组(L组)和气管插管组(T组),氯胺酮组(K组),每组20例。分别观察各组在麻醉诱导前、麻醉诱导后及喉罩或导管置入前、置入后、拔除前、拔除后的血氧饱和度(SpO2)、心率(HR)、平均动脉压(MAP)和术后恢复情况。结果 L组置入喉罩后和拔除喉罩后的MAP、HR低于T组(P<0.05),术后呼吸系统并发症L组低于T组(P<0.05),术中肢动人数K组高于L组及T组。结论喉罩在小儿先天性心脏病介入治疗的麻醉中安全,可行。
Objective To investigate the superiority of laryngeal mask in pediatric congenital heart disease interventional anesthesia. Methods Sixty children with interventional therapy of congenital heart disease were randomly divided into laryngeal mask group (L group), tracheal intubation group (T group) and ketamine group (K group), with 20 cases in each group. SpO2, HR and MAP were observed before anesthesia induction, after induction of anesthesia and before or after laryngeal mask or catheter implantation, respectively. And postoperative recovery. Results The MAP and HR of L group after laryngeal mask placement and laryngeal mask removal were lower than those of T group (P <0.05). The postoperative respiratory complications in L group were lower than those in T group (P <0.05) K group than L group and T group. Conclusions Laryngeal mask is safe and feasible in the anesthesia of pediatric congenital heart disease interventional therapy.
