Methods Sixty ASAⅠ-Ⅱpatients who underwent general anaesthesia between October to December 2009 were randomly divided into three groups. The patients in the trial group accepted R-SGB by C6 route with 1% lidocaine (10 mL) 15 minutes before induction of general anesthesia; the patients in control group 1 were injected with 10 mL physiological saline in the same way before the induction; the patients in control group 2 underwent the intramuscular injection of 2% lidocaine (5 mL) before the induction. The changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hear rate (HR), electrocardiogram (ECG), oxygen saturation (SpO2) and heart rate-systolic blood pressure product (RPP) before and after endotracheal intubation were observed and recorded. Results In the trial group, SBP, MAP, and DBP decreased significantly after the induction; HR and RPP increased evidently at the laryngeal exposure compared with the baseline values (Plt;0.01) and recovered three minutes after the intubation. In the control group 1 and 2, SBP, MAP, and DBP decreased significantly after induction (Plt;0.01); SBP, MAP, DBP, HR and RPP increased apparently at the laryngeal exposure compared with the baseline values (Plt;0.01), and the raise continued until five minutes after endotracheal intubation. The difference in the raise between the control groups and the trial group was significant (Plt;0.05 or Plt;0.01). Conclusion R-SGB may effectively inhibit the cardiovascular response during endotracheal intubation under the general anesthesia and can be used to control the negative reaction during the induction.
