The cardiovascular effects of fibrescope-guided nasotracheal intubation were compared to those of a control group of patients who were intubated using the Macintosh laryngoscope. The 60 patients studied received a standard anaesthetic technique which included a muscle relaxant and were allocated randomly to one of two groups immediately before tracheal intubation. Systolic and diastolic arterial pressures in the fibreoptic group were significantly lower than in the control group during the first minute after intubation. The maximum increase in diastolic pressure was significantly lower in the fibreoptic group. The heart rate in the fibreoptic group was significantly higher than in the control group during all five minutes after intubation. The maximum increase in heart rate was significantly higher in the fibreoptic group. The cardiovascular responses to fibreoptic nasotracheal intubation under general anaesthesia should not cause undue concern in fit patients, but appropriate measures should be taken to prevent excessive tachycardia in compromised patients.
将纤维支气管镜引导下经鼻气管插管的心血管效应与使用麦金托什喉镜进行插管的对照组患者的效应进行了比较。所研究的60例患者接受了包括肌肉松弛剂在内的标准麻醉技术，并在气管插管前立即随机分为两组。纤维光学组在插管后第一分钟的收缩压和舒张压显著低于对照组。纤维光学组舒张压的最大升高显著更低。纤维光学组在插管后的所有五分钟内心率显著高于对照组。纤维光学组心率的最大升高显著更高。全身麻醉下纤维支气管镜引导下经鼻气管插管的心血管反应在健康患者中不应引起过度担忧，但对于病情较重的患者应采取适当措施预防过度心动过速。
