We aimed to evaluate the efficacy of using airway ultrasonography to select the correct tracheal tube size and insertion depth in pediatric patients who underwent cleft repair surgery as a way to decrease airway complications and adverse events during perioperative periods. Fifty-one patients (age < 28 months) were consecutively divided into conventional (n = 28) and ultrasound (n = 23) groups. Tracheal tube size and insertion depth were determined using the age-based formula and auscultation in the conventional group, whereas using ultrasonographic measurement of subglottic diameter with auscultation and lung ultrasonography in the ultrasound group. We evaluated the initially selected tube size, insertion depth, ventilatory indices, and the incidence of airway complications and adverse events. Tube insertion depth (median [interquartile range]) was significantly greater in the ultrasound group than in the conventional group (13.5 cm [12.5–14.0] vs 13.0 cm [11.8–13.0], P = 0.045). The number of complications and adverse events was significantly higher in the conventional group than in the ultrasound group (32.1% vs 4.3%, P = 0.013). Airway ultrasound application could reduce airway-related complications and adverse events by determining the appropriate tracheal tube size and insertion depth.

我们旨在评估使用气道超声检查在接受唇裂修复手术的儿科患者中选择正确气管插管尺寸和插入深度的有效性，以减少围手术期气道并发症和不良事件。51 名患者（年龄 < 28 个月）被连续分为常规组（n = 28）和超声组（n = 23）。常规组采用基于年龄的公式和听诊确定气管导管的大小和插入深度，而超声组采用超声测量声门下直径与听诊和肺超声检查。我们评估了最初选择的导管尺寸、插入深度、通气指数以及气道并发症和不良事件的发生率。P  = 0.045）。常规组并发症和不良事件的数量明显高于超声组（32.1% vs 4.3%，P  = 0.013）。通过确定合适的气管插管尺寸和插入深度，气道超声应用可以减少气道相关并发症和不良事件。
