经口或经鼻纤支镜引导插管对心血管的影响

目的：观察经口或经鼻纤支镜引导插管对心血管的影响。方法：16例择期手术病人，均系插管困难，随机分为经口组和经鼻组，在神经安定镇痛麻醉（NLA）加表麻下进行插管，监测插管前后血氧饱和度，血压及心率的变化。结果：与插管前相比，插管后SPO2显降低（P＜0．01），HR，SBP，DBP，MAP，RPP均显增高（P＜0．05或P＜0．01），插管后经鼻组与经口组相比，HR，SBP，MAP，RPP上升更显（P＜0．01），SPO2和DBP变化不显（P＞0．05），结论：NLA加表麻下纤支镜插管心血管反应较大，其中经鼻途径更甚于经口途径。

Cardiovascular response of peroral/pernasal endotracheal intubation through fiberbronchoscope

Objective To investigate the cardiovascular response of peroral/pernasal endotracheal intubation through fiberbronchoscope. Methods 16 patients undergoing elective operation were divided into two groups randomly, group O:peroral endotracheal intubation through fiberbronchoscope and group N:pernasal endotracheal intubation through fiberbronchoscope. Oxygen Saturation of blood (SpO2), arteria blood pressure (SBP, DBP and MAP) and heart rate (HR) were detected before and after endotracheal intubation. Results After endotracheal inbution, SpO2 was significantly decreased (p<0.01), and HR, SBP, DBP, MAP, RPP were significantly increased (p<0.05 or p<0.01). The change of HR of group N, as well as the changes of SBP, MAP and RPP, were more significant than that of group O (p<0.01), while the changes of SpO2 and DBP between two groups had no significant differences (p<0.05). Conclusion Endotracheal intubation through fiberbronchoscope under NLA with topical anesthesia had significant effects on cardiovascular response, the effects of pernasal intubation were more than that of peroral intubation.
