The problem of difficult and failed intubation led to increased development of equipment for airway management. A number of supraglottic airways have now been developed to facilitate the passage of tracheal tubes. Conventional PVC tracheal tubes are recommended for intubation through the air-Q ILA. No study has compared different PVC tubes for blind intubation through air-Q ILA. Thus, we undertook this prospective, randomised, single blind study to compare two PVC tracheal tubes with different designs viz. conventional PVC tracheal tube (TT) and Parker flex-tip TT with regards to success rate, ease of intubation and total time required for successful intubation through air-Q ILA.
One hundred patients of either sex, aged 18-60 years, belonging to American Society of Anesthesiologists (ASA) physical status class I and II scheduled for elective surgery under general anesthesia requiring endotracheal intubation were included in the study. Blind intubation using conventional PVC TT and Parker flex-tip tube was done in group A ( = 50) and group B ( = 50), respectively.
The first attempt success rate in Parker flex-tip TT was significantly more as compared to conventional PVC TT ( = 0.002). Success rate of intubation was significantly more in Parker flex-tip TT as compared to conventional PVC TT ( = 0.004). The intubation was significantly easy in Parker flex-tip tube as compared to conventional PVC TT ( = 0.002). Total time of intubation was less in Parker flex-tip tube as compared to PVC TT ( = 0.043).
Unique design of the Parker Flex-tip TT resulted in increase in success rate, first attempt success rate and ease of intubation in group B in present study.
气管插管困难和失败的问题促使气道管理设备不断发展。目前已研发出多种声门上气道装置以方便气管导管的插入。推荐使用传统聚氯乙烯（PVC）气管导管经Air-Q ILA进行插管。尚无研究比较不同的PVC导管经Air-Q ILA进行盲探插管的效果。因此，我们开展了这项前瞻性、随机、单盲研究，比较两种不同设计的PVC气管导管，即传统PVC气管导管（TT）和派克软头TT，在经Air-Q ILA成功插管的成功率、插管 ease以及成功插管所需的总时间方面的差异。
本研究纳入了100例年龄在18至60岁之间、美国麻醉医师协会（ASA）身体状况分级为I级和II级、计划在全身麻醉下进行择期手术且需要气管插管的患者，性别不限。分别在A组（n = 50）和B组（n = 50）中使用传统PVC TT和派克软头导管进行盲探插管。
与传统PVC TT相比，派克软头TT的首次尝试成功率显著更高（P = 0.002）。与传统PVC TT相比，派克软头TT的插管成功率显著更高（P = 0.004）。与传统PVC TT相比，派克软头导管的插管操作显著更容易（P = 0.002）。与PVC TT相比，派克软头导管的总插管时间更短（P = 0.043）。
在本研究中，派克软头TT的独特设计使B组的成功率、首次尝试成功率以及插管 ease均有所提高。
