Advancement of the endotracheal tube through a fibreoptic scope can sometimes prove to be challenging in obese patients. The Parker Flex-Tip endotracheal tube was developed with a curved and tapered distal tip to facilitate easier placement in the trachea. This study examined the use of the Parker Flex-Tip tube as compared to standard endotracheal tubes in patients with a body mass index of 30 or greater.
Sixty patients undergoing surgery requiring general anaesthesia were randomised into two groups. Using the fibreoptic scope, one group was intubated with the Parker Flex-Tip tube and the other group with a standard polyvinyl Portex tube. The time for intubation and the number of attempts required to place the endotracheal tube were measured and recorded.
Using the Mann-Whitney U rank sum test, the median time needed for intubation with the two types of endotracheal tubes did not show a significant difference. The chi-square analyses were conducted for the number of attempts needed to place the endotracheal tubes, which also did not demonstrate any significant difference.
Parker Flex-Tip endotracheal tube was not superior to the standard endotracheal tubes for fibreoptic intubation in obese patients.
对于肥胖患者，通过纤维支气管镜推进气管导管有时颇具挑战性。帕克可弯曲尖端气管导管的远端呈弯曲且渐细的形状，以便于更轻松地置入气管。本研究对比了帕克可弯曲尖端气管导管与标准气管导管在体重指数为30或更高的患者中的使用情况。
60例接受全身麻醉手术的患者被随机分为两组。使用纤维支气管镜，一组用帕克可弯曲尖端气管导管进行插管，另一组用标准聚乙烯波特克斯气管导管插管。测量并记录插管时间以及放置气管导管所需的尝试次数。
使用曼-惠特尼U秩和检验，两种气管导管插管所需的中位时间无显著差异。对放置气管导管所需的尝试次数进行卡方分析，结果也未显示出任何显著差异。
在肥胖患者的纤维支气管镜插管中，帕克可弯曲尖端气管导管并不优于标准气管导管。
