To preliminary evaluate the application of SaCoVLM™ video laryngeal mask airway in airway management of general anesthesia.
We recruited 100 adult patients (ages 18-78 years, male 19, female 81, weight 48-90 kg) with normal predicted airway (Mallampati I ~ II, unrestricted mouth opening, normal head and neck mobility) and ASA I-II who required general anaesthesia. The SaCoVLM™ was inserted after anesthesia induction and connected with the anesthesia machine for ventilation. Our primary outcome was glottic visualization grades. Secondary outcomes included seal pressure, success rate of insertion, intraoperative findings (gastric reflux and contraposition), gastric drainage and 24-h complications after operation.
The laryngeal inlet was exposed in all the patients and shown on the video after SaCoVLM™ insertion. The status of glottic visualization was classified: grade 1 in 55 cases, grade 2 in 23 cases, grade 3 in 14 cases and grade 4 in 8 cases. The first-time success rate of SaCoVLM™ insertion was 95% (95% CI = 0.887 to 0.984), and the total success rate was 96% (95% CI = 0.901 to 0.989). The sealing pressure of SaCoVLM™ was 34.1 ± 6.2 cmHO and the gastric drainage were smooth. Only a small number of patients developed mild complications after SaCoVLM™ was removed (such as blood stains on SaCoVLM™ and sore throat).
The SaCoVLM™ can visualize partial or whole laryngeal inlets during the surgery, with a high success rate, a high sealing pressure and smooth gastroesophageal drainage. SaCoVLM™ could be a promise new effective supraglottic device to airway management during general anesthesia.

初步评估 SaCoVLM™视频喉镜在全身麻醉气道管理中的应用。
我们招募了 100 名成年患者（年龄 18-78 岁，男性 19 名，女性 81 名，体重 48-90kg），预计气道正常（Mallampati I~II 级，张口不受限，头颈部活动正常），ASA I-II 级，需全身麻醉。全身麻醉诱导后插入 SaCoVLM™并与麻醉机连接进行通气。主要结局是声门可视化分级。次要结局包括密封压、插入成功率、术中发现（胃反流和对位不良）、胃引流和术后 24 小时并发症。
所有患者的喉入口均暴露，并在 SaCoVLM™插入后在视频上显示。声门可视化状态分类为：1 级 55 例，2 级 23 例，3 级 14 例，4 级 8 例。SaCoVLM™首次插入成功率为 95%（95%CI=0.8870.984），总成功率为 96%（95%CI=0.9010.989）。SaCoVLM™的密封压为 34.1±6.2cmHO，胃引流通畅。SaCoVLM™取出后仅有少数患者出现轻度并发症（如 SaCoVLM™上有血迹和咽痛）。
SaCoVLM™可在手术中可视化部分或全部喉入口，成功率高，密封压高，胃食管引流顺畅。SaCoVLM™可能是一种新的有效的全身麻醉气道管理的声门上装置。
