Orotracheal intubation is the standard technique for airway management, but several untoward airway complications are possible with this method. To avoid airway trauma caused by the tube tip during intubation, the Parker Flex-Tip tube (PFT), which has a flexible, tapered tip, was developed. It has been reported that the PFT facilitates fiberoptic orotracheal intubation and introducer-guided tracheal intubation. In this study, we compared the PFT to a standard endotracheal tube (SET), regarding the time of intubation during conventional orotracheal intubation and the incidence of postoperative sore throat and hoarseness. One hundred and thirty-four patients scheduled for elective anesthesia using orotracheal intubation were randomized to either the PFT or SET and 132 completed the study. The intubators were classified into three groups: staff anesthesiologists, inexperienced anesthesiologists, and anesthesia trainees. The tube was selected by another anesthesiologist and the time required for intubation was measured. PFT did not shorten the time required for intubation and did not reduce the incidence of sore throat and hoarseness. However, a detailed analysis revealed that the PFT decreased the time required for intubation in the anesthesia trainee group. The PFT may help novice intubators to conduct a smooth intubation.
经口气管插管是气道管理的标准技术，但该方法可能会出现一些不良气道并发症。为避免插管过程中管尖造成气道损伤，研发了具有可弯曲锥形尖端的派克柔性尖端气管导管（PFT）。据报道，PFT有助于纤维光学经口气管插管和引导器引导的气管插管。在本研究中，我们比较了PFT与标准气管导管（SET）在传统经口气管插管时的插管时间以及术后咽痛和声音嘶哑的发生率。134例计划行择期经口气管插管麻醉的患者被随机分为PFT组或SET组，132例完成了研究。插管人员分为三组：麻醉科医生、经验不足的麻醉医生和麻醉实习生。由另一名麻醉医生选择导管并测量插管所需时间。PFT并没有缩短插管所需时间，也没有降低咽痛和声音嘶哑的发生率。然而，详细分析显示，PFT缩短了麻醉实习生组的插管所需时间。PFT可能有助于新手插管人员顺利完成插管。
