A variety of extraglottic airway devices (EADs) are available. Main concerns with EADs are protection against aspiration and ability to ventilate patients with high airway pressures. Baska mask meets these criteria and is the only third-generation device available for clinical use.
After institutional ethics committee approval and informed consent were obtained, this prospective study was performed in 100 adult patients undergoing surface surgeries at a tertiary referral centre. The primary outcome was the success rate of insertion, while the secondary outcomes were the sealing pressure, stability of the device and the perioperative complications of Baska mask. We then compared it with other currently used EADs.
The first attempt at insertion and overall success rates, showed values of 81% and 98%, respectively. Insertion was quick (median 12; interquartile range [IQR] 9-15 s). The mask sealing pressure, was 35 cmHO (median [IQR 20-50 cmHO]). Also, the mask remained stable in 95% of patients intraoperatively. Sore throat and dysphagia were seen in 37% and 24% of patients, respectively. No patient had laryngospasm or desaturation at any time. It compared favourably well with other EADs, while achieving higher sealing pressures.
We found that the Baska mask performs well with excellent first attempt at insertion and overall success rates, higher sealing pressures and minimal complications compared to currently used EADs in clinical anaesthesia.
有多种声门外气道装置（EADs）可供使用。EADs的主要关注点在于防止误吸以及对气道压力高的患者进行通气的能力。巴斯卡面罩符合这些标准，是唯一可用于临床的第三代装置。
在获得机构伦理委员会批准并取得知情同意后，这项前瞻性研究在一家三级转诊中心对100例接受体表手术的成年患者进行。主要结局是插入成功率，次要结局是密封压力、装置稳定性以及巴斯卡面罩的围手术期并发症。然后我们将其与其他目前使用的EADs进行比较。
首次插入尝试成功率和总体成功率分别为81%和98%。插入迅速（中位数为12秒；四分位间距[IQR]为9 - 15秒）。面罩密封压力为35cmH₂O（中位数[IQR 20 - 50cmH₂O]）。此外，术中95%的患者面罩保持稳定。分别有37%和24%的患者出现咽痛和吞咽困难。任何时候均无患者发生喉痉挛或血氧饱和度下降。与其他EADs相比，它表现良好，同时实现了更高的密封压力。
我们发现，与临床麻醉中目前使用的EADs相比，巴斯卡面罩在首次插入尝试和总体成功率方面表现出色，密封压力更高，并发症极少。
