目的探讨喉罩与气管导管在小儿麻醉中的利弊。方法选择60例择期手术患儿随机分为两组,即喉罩组(lma组,30例)和气管插管组(tt组,30例),全麻诱导给予咪达唑仑0.05 mg/kg,芬太尼2.0ug/kg,丙泊酚1.0 mg/kg,卡肌宁0.6 mg/kg,在药物完全起效后行lma和tt置入。分别记录两组患儿麻醉诱导前、lma(tt)置入前、置入后以及术后拔除lma(tt)后的BP、HR、SPO2的数值,并对置入lma和tt的一次成功率进行比较。结果两组患儿在麻醉诱导前及lma(tt)置入前的BP、HR、SPO2值相比较无显著差异(P>0.05),而在置入后和术后拔除lma(tt)时lma组的map、hr显著低于tt组(P<0.05)。结论喉罩通气装置使用简单、无创伤,对大多数成人和小儿都适用。若掌握好喉罩使用的适应证和禁忌证,在小儿麻醉中的应用值得推广。
Objective To explore the advantages and disadvantages of laryngeal mask and endotracheal tube in pediatric anesthesia. Methods Sixty children undergoing elective surgery were randomly divided into two groups: LMA group (n = 30) and tracheal intubation group (n = 30). Induction of midazolam 0.05 mg / kg , Fentanyl 2.0ug / kg, propofol 1.0 mg / kg, cardiomycin 0.6 mg / kg, lma and tt after the drug is fully effective. The data of BP, HR and SPO2 before lma (tt) implantation, after lm (tt) implantation and after lm (tt) ligation were recorded respectively in the two groups, and the success rates of lma and tt Compare. Results There was no significant difference in BP, HR and SPO2 before anesthesia induction and before lma (tt) implantation (P> 0.05), but lma Group map, hr was significantly lower than the tt group (P <0.05). Conclusions Laryngeal mask ventilation is easy to use and noninvasive, suitable for most adults and children. If mastered the use of laryngeal mask indications and contraindications in the application of pediatric anesthesia is worth promoting.
