Supreme喉罩与Ambu AuraOnce喉罩用于乳腺整形手术的可行性与安全性比较

Comparative study of feasibility and safety of Ambu AuraOnce laryngeal mask and Supreme laryngeal mask in patients undergoing breast surgery

目的比较Supreme喉罩与Ambu AuraOnce喉罩用于乳腺整形手术患者的可行性和安全性。方法选择100例择期行乳房整形手术的全麻患者,ASAⅠ~Ⅱ级,年龄17~50岁,BMI<30 kg/m^2,随机分为Supreme喉罩组(S组)与Ambu AuraOnce喉罩组(A组)。记录2组患者喉罩置入时间、置入次数、置入过程中调整情况、密封压、气道压、置入成功后纤维支气管镜下对位情况及术后并发症发生情况。结果 2组患者的喉罩置入时间、置入成功率、置入过程中调整情况、纤维支气管镜下对位情况及术后并发症发生情况差异均无统计学意义,S组的密封压和气道压高于A组[(23.7±3.7)cm H_2O vs.(20.7±3.2)cm H_2O,(11.0±1.7)cm H_2O vs.(10.4±1.0)cm H_2O,P均<0.05]。结论 Supreme喉罩与Ambu AuraOnce喉罩均可安全有效地用乳腺整形手术患者,置入时间短、成功率高、并发症低,Supreme喉罩较Ambu AuraOnce喉罩能获得更高的密封压。

Objective To compare the feasibility and safety ofAmbu AuraOnce laryngeal mask and LMA Supreme in patients undergoing breast surgery. Methods One hundred patients, ASA Ⅰ- Ⅱ, 17-50 years old, BMI 〈 30 kg/m^2 scheduled for breast surgery, were randomly divided into two groups： the Supreme LMA group （group S） and the Ambu AuraOnce group （group A）. Time for insertion, attempts, manipulation, oropharyngeal leak pressure, airway peak pressure, fiberoptic grade of view and complications were recorded and compared between the two groups. Results There was no statistical difference between the two groups in insertion time, success rate, manipulation, fiberoptic grade of view and complications. Oropharyngeal leak pressures and airway peak pressures in group S were significantly higher than those in group A. Conclusion Both LMA Supreme and Ambu AuraOnce laryngeal mask can be effectively and safely used in patients undergoing breast surgery, with short insertion time, high success rate and low complications. LMA Su- preme provides a higher oropharyngeal leak pressure than Ambu AuraOnce laryngeal mask.
