The design of the endotracheal tube might be an important factor in the incidence of injurious complications during nasotracheal intubation.
Primary aim: to compare the parker flex tip (PFT) and the preformed nasal (PNT) tubes regarding the ease of insertion during nasotracheal intubation in children undergoing adenotonsillectomy. Secondary aim: to verify the incidence of traumatic complications of both types of tubes during nasotracheal intubation in children undergoing adenotonsillectomy.
100 patients aged between 4 and 10 years ASA physical status I-II scheduled for adenotonsillectomy were divided into two groups; Group PFT: Patients were nasally intubated using the parker flex-tip endotracheal tube, Group PNT: Patients were nasally intubated using the preformed nasal tube. Ease of insertion of the ETT, degree of trauma and the time of intubation was measured.
ETT was easily inserted without any resistance in 24% of patients of the PFT group versus 12% of patients in the PNT group. ETT could not be passed through the right or left nostrils in 20% of patients of the PNT group relative to only 4% of patients of the PFT group. Incidence of trauma to the nasal mucosa was significantly higher in patients of the PNT group than patients of the PFT group. Duration of intubation was statistically significantly longer among patients of the PNT group than patients of the PFT group.
It seems that the flexible tapered tip of the PFT tube has led to easier insertion through the nasal passages as well as less trauma to the nasal mucosa in children having nasopharyngeal pathology in the form of adenoids. At the same time, the duration of intubation was less in the PFT group relative to the control group in spite of the more familiarity of the investigator with the standard portex tube.
气管内导管的设计可能是鼻气管插管期间有害并发症发生率的一个重要因素。
主要目的:比较派克弯曲头(PFT)导管和预制鼻型(PNT)导管在腺样体扁桃体切除术患儿鼻气管插管时的插入难易程度。次要目的:验证这两种类型的导管在腺样体扁桃体切除术患儿鼻气管插管期间的创伤性并发症发生率。
100例年龄在4至10岁、美国麻醉医师协会(ASA)身体状况分级为I-II级、计划行腺样体扁桃体切除术的患者被分为两组;PFT组:患者使用派克弯曲头气管内导管进行鼻插管;PNT组:患者使用预制鼻型导管进行鼻插管。测量气管内导管的插入难易程度、创伤程度和插管时间。
PFT组24%的患者气管内导管易于插入且无任何阻力,而PNT组为12%。PNT组20%的患者气管内导管无法通过右鼻孔或左鼻孔,而PFT组仅为4%。PNT组患者鼻黏膜创伤的发生率显著高于PFT组患者。PNT组患者的插管持续时间在统计学上显著长于PFT组患者。
似乎PFT导管的柔性锥形头使得在患有腺样体形式的鼻咽部病变的儿童中更容易通过鼻腔插入,并且对鼻黏膜的创伤更小。同时,尽管研究者对标准波特克斯导管更熟悉,但PFT组的插管持续时间相对于对照组更短。
