To evaluate and compare the Truview PCD and C-MAC laryngoscopes to the standard Macintosh laryngoscope in paediatric patients.
One hundred and fifty ASA I-II patients in the age group of 1-6 years (10-20 kg) scheduled for elective surgery were randomised into three equal groups for laryngoscopy and intubation with either Truview PCD (Group T), C-MAC (Group C) or Macintosh (Group M) laryngoscopes under general anaesthesia. Percentage of glottic opening (POGO) score, application of external laryngeal manoeuvre, time to intubation, number of attempts at intubation, failed intubations, episodes of desaturation and trauma caused were recorded and statistically analysed. A p value of <0.05 was taken as significant.
POGO scores were significantly better with Truview PCD as compared with C-MAC and Macintosh laryngoscopes (94.7 ± 12.9/82 ± 25.0/85.1 ± 17.1; p < 0.01). There were no failed attempts, episodes of desaturation or trauma in any of the patients. The mean intubation time taken was 19.2 s in group T, 12.3 s in group C and 10.7 s in group M, respectively. There is a statistically significant difference among groups (p < 0.01). Eight patients in group T, 21 out of 50 patients in group C and 19 out of 50 patients in group M needed OELM, respectively. There is significant difference among the groups (p < 0.01) CONCLUSION: Using Truview PCD to assist intubation offers excellent view field of glottic opening after OLEM and the mean time taken is less than 20 s. The Truview PCD tool is suitable for paediatric patients.
在儿科患者中评估并比较Truview PCD喉镜和C-MAC喉镜与标准Macintosh喉镜。
将150例年龄在1至6岁（10至20千克）、拟行择期手术的美国麻醉医师协会（ASA）I-II级患者随机分为三组，在全身麻醉下分别使用Truview PCD喉镜（T组）、C-MAC喉镜（C组）或Macintosh喉镜（M组）进行喉镜检查和插管。记录声门开放百分比（POGO）评分、外部喉部操作的应用、插管时间、插管尝试次数、插管失败情况、血氧饱和度下降发作情况及造成的创伤，并进行统计学分析。p值<0.05被视为具有显著性。
与C-MAC喉镜和Macintosh喉镜相比，Truview PCD喉镜的POGO评分显著更高（94.7±12.9/82±25.0/85.1±17.1；p<0.01）。所有患者均无插管失败、血氧饱和度下降发作或创伤情况。T组、C组和M组的平均插管时间分别为19.2秒、12.3秒和10.7秒。组间存在统计学显著差异（p<0.01）。T组8例患者、C组50例患者中的21例以及M组50例患者中的19例分别需要进行外部喉部操作。组间存在显著差异（p<0.01）。结论：使用Truview PCD喉镜辅助插管在进行外部喉部操作后可提供良好的声门开放视野，且平均用时不到20秒。Truview PCD工具适用于儿科患者。
