General anesthesia (GA) is considered the gold standard for external dacryocystorhinostomy (DCR) surgery. There are few reports about laryngeal mask airway (LMA) use in DCR surgery. The aim of this study was to compare the use of endotracheal intubation (ETT) vs LMA for airway management during DCR surgery.
Ninety patients were randomized to two groups. In the group C, ETT and in the group L, classic LMA was used to maintain and protect the airway during the procedure. Hemodynamic data before, after intubation or LMA insertion and after skin incisions were recorded. Coughing and straining at the end of anesthesia and postoperative nausea and vomiting (PONV) were recorded.
In the group L, the mean arterial pressure and the heart rate after LMA insertion and after the skin incisions were significantly lower than the group C (p < 0.05). Furthermore, incidence of coughing, straining at the end of anesthesia and PONV was lower in the group L than the group C (p < 0.05).
LMA can be used in external DCR, to decrease the hemodynamic changes, to decrease coughing, straining at the end of anesthesia and the incidence of PONV.
全身麻醉（GA）被认为是外路泪囊鼻腔吻合术（DCR）手术的金标准。关于喉罩气道（LMA）在DCR手术中的应用报道较少。本研究的目的是比较在DCR手术中气管插管（ETT）与LMA用于气道管理的情况。
90例患者被随机分为两组。C组使用ETT，L组在手术过程中使用经典LMA来维持和保护气道。记录插管或插入LMA前、后以及皮肤切开后的血流动力学数据。记录麻醉结束时的咳嗽和用力情况以及术后恶心呕吐（PONV）情况。
L组在插入LMA后和皮肤切开后的平均动脉压和心率显著低于C组（p < 0.05）。此外，L组麻醉结束时的咳嗽、用力情况以及PONV的发生率低于C组（p < 0.05）。
LMA可用于外路DCR手术，以减少血流动力学变化，减少麻醉结束时的咳嗽、用力情况以及PONV的发生率。
