目的探讨支气管镜检查过程中的自主神经系统的相互作用。方法 100例患者根据术前准备方法不同随机分为两组:A组:2%利多卡因吸入麻醉的同时于术前30min肌肉注射阿托品1mg;B组:2%利多卡因吸入麻醉。分别记录术前(T1)、通过咽部(T2)、通过声门(T3)、气管内注入2%利多卡因后(T4)、操作过程中(T5)、结束时(T6)的心率(HR)、血氧饱和度(SPO2),并记录T1和T6的血压(BP)等数据。结果组内与术前对比:两组HR均从T3开始增快,差异具有显著性;SPO2:A组各时间点差异无显著性,B组从T3开始下降,差异具有显著性;BP:A组收缩压(SBP)差异无显著性;B组SBP升高,差异具有显著性。组间比较:HR在T1、T2、T3和T6时A>B,差异具有显著性,但在T4和T5时两组间差异无显著性。结论阿托品在支气管镜检查过程中能使患者保持更稳定的HR、SPO2及SBP。对支气管镜检查过程中自主神经系统的协调稳定起到一定的作用。
Objective To explore the autonomic nervous system interaction during bronchoscopy. Methods 100 patients were randomly divided into two groups according to different preoperative preparation methods: group A: 2% lidocaine was administered intramuscularly with atropine 1 mg 30 min before anesthesia; group B: 2% lidocaine was inhaled anesthetized. The heart rate (T6), heart rate (T6), end-tidal volume (T1), pharynx HR), oxygen saturation (SPO2), and record T1 and T6 blood pressure (BP) and other data. Results Compared with preoperative, HR in both groups increased from T3, the difference was significant. SPO2: A group at each time point was no significant difference, B group began to decline from T3, the difference was significant; BP: A Group SBP SBP no significant difference; Group B SBP increased, the difference was significant. Comparisons between groups: HR at A, B, T2, T3 and T6, the difference was significant, but at T4 and T5 there was no significant difference between the two groups. Conclusions Atropine allows patients to maintain HR, SPO2, and SBP more consistently during bronchoscopy. Bronchoscopy during the autonomic nervous system coordination and stability play a role.
