普通气管导管预热后用于经鼻明视气管插管的临床观察

Clinical Observation of Viewable Nasotracheal Intubation with Preheated Common Endotracheal Tube

目的:探讨普通气管导管预热后用于经鼻明视气管插管的临床效果。方法:将70例ASAⅠ-Ⅱ级、需经鼻气管插管的择期手术患者随机均分为两组,常规麻醉诱导后,分别采用预热后的普通气管导管(实验组)和鼻气管导管(对照组)行经鼻明视气管插管。记录麻醉诱导后、气管插管时和气管插管后1、3、5min时的血压(BP)和心率(HR)及其观察期的最大值,并计算各时点心率-收缩压乘积(RPP),记录气管插管时间和插管顺利程度,并对患者鼻黏膜损伤情况和术中导管折弯发生率进行观察。结果:两组患者间各时点的BP、HR和RPP及最大值,气管插管时间和插管顺利程度,以及鼻黏膜损伤情况比较差异无显著性统计学意义(P>0.05),而对照组术中导管折弯发生率较高(P<0.05)。结论:普通气管导管预热后用于经鼻明视气管插管可取得良好的临床效果,且成本低廉,具有较好临床实用价值。

Objective：To explore the clinical effect of viewable nasotracheal intubation with preheated common endotracheal tube. Methods：Seventy ASA I or Ⅱ patients scheduled for elective operation requiring nasotracheal intubation were randomly divided equally into two group,After the routine anesthesia induction,vicwable nasotracheal intubation was performed with preheated common endotraeheal tube（experimental group） or nasotracheal tube（control group） respectively.The blood pressure（BP） and heart rate（ttR） were recorded after anesthesia induction,at intubation,and 1,3 and 5 minute after intubation.The maximum values of BP and HR during the observation period were noted,and the rate pressure product（RPP） at each time point was calculated.The time and successful degree of intubation,and the status of injury of nasat mucosa and bend of robe were observed.Results：The BP, HR and RPP at each time point,the maximum values of BP and HR,the time and successful degree of intubation,and the status of injury of nasal mucosa in two groups has no difference（P〉0.05）.The incidence of bend of tube in experimental group was lower than that in control group（P〈0.05）.Conclusion：Viewable nasotracheal intubation with preheated common endotracheal tube has good clinical effect,low cost and clinically practical worth.
