BACKGROUND AND AIMS
The available supraglottic devices (SGDs) used as conduits for fibreoptic bronchoscope-guided intubation (FOI) in children have shown no difference in terms of time taken for tracheal intubation or success rate on the first attempt. However, several difficulties have been reported during the removal of the SGD after FOI. This study aimed to compare the feasibility of the safe removal of conduits after FOI through BlockBuster Laryngeal Mask Airway (BlockBuster) and Air-Q Intubating Laryngeal Airway (Air-Q) in paediatric patients.
METHODS
This was a randomised comparative study conducted on 66 children between the ages of 1 and 8 years undergoing elective surgeries under general anaesthesia. FOI was performed using BlockBuster or Air-Q as a conduit in study groups. The primary outcome was the time taken and the ease of removing the conduit after FOI. The secondary outcomes included adverse events during conduit removal. We also compared the number of attempts and time taken for the successful placement of these SGDs, as well as for FOI utilising them as conduits. An independent samples -test was used for normally distributed variables, and a Chi-square test for qualitative variables, with statistical significance set at < 0.05.
RESULTS
The ease of removing the conduit was comparable in both groups ( = 0.21). The mean time taken to remove the conduit was lower in the Blockbuster group [28.03 [standard deviation (SD: 5.90] [95% confidence interval (CI): 26.01, 30.04] seconds] compared to the control group (30.27 (SD: 5.54) (95% CI: 28.38, 32.16) seconds; = 0.03). There were no adverse events during conduit removal in the BlockBuster and the Air-Q group. The number of attempts ( = 0.317) and time taken for the successful placement of SGDs ( = 0.054) in the study groups and FOI through them was found to be comparable ( = 0.692).
CONCLUSION
For FOB-guided tracheal intubation in paediatric patients, BlockBuster is comparable to Air-Q, and it may be a useful alternative.
背景与目的
现有的用于儿童纤维支气管镜引导插管（FOI）的声门上装置（SGD）在气管插管所需时间或首次尝试成功率方面并无差异。然而，有报道称在FOI后移除SGD时存在一些困难。本研究旨在比较在儿科患者中，通过BlockBuster喉罩气道（BlockBuster）和Air-Q气管插管型喉罩气道（Air-Q）在FOI后安全移除导管的可行性。
方法
这是一项对66名年龄在1至8岁接受全身麻醉下择期手术的儿童进行的随机对照研究。在研究组中使用BlockBuster或Air-Q作为导管进行FOI。主要结局是FOI后移除导管所需的时间和难易程度。次要结局包括导管移除过程中的不良事件。我们还比较了成功放置这些SGD以及将它们用作导管进行FOI的尝试次数和所需时间。对于正态分布变量使用独立样本t检验，对于定性变量使用卡方检验，统计学显著性设定为P<0.05。
结果
两组在移除导管的难易程度方面具有可比性（P = 0.21）。与对照组（30.27（标准差：5.54）（95%置信区间：28.38，32.16）秒；P = 0.03）相比，BlockBuster组移除导管的平均时间更低[28.03（标准差：5.90）[95%置信区间：26.01，30.04]秒]。在BlockBuster组和Air-Q组中，导管移除过程中均未出现不良事件。研究组中成功放置SGD的尝试次数（P = 0.317）和所需时间（P = 0.054）以及通过它们进行FOI的时间（P = 0.692）具有可比性。
结论
对于儿科患者的FOB引导气管插管，BlockBuster与Air-Q相当，可能是一种有用的替代方法。
