The effects lidocaine on blood pressure and heart rates after nasotracheal intubation

In 45 patients undergoing oromaxillofacial surgery under the general anesthesia, the blood pressure (systolic and diastolic) and heart rates were measured to evaluate the effects of the nasotracheal intubation on the hemodynamic changes. And for evaluating the effects of lidocaine on the blood pressure and heart rates after nasotracheal intubation, lidocaine HCl 1.0mg/kg and 1.5mg were administered intravenously. The following results were obtained: 1. The significant increase of systolic blooc pressure were olserved from one to three minutes after nasotracheal intubation in patients without I.V. lidocaine injection. Compared with the systolic blood pressure before nasotracheal intubation. 2. In patients with Ⅳ lidocaine, 1mg/kg before masotracheal intubation. There were the significant increses of syotolic blood pressure of one and two minutes after nasotracheal intubation compared with systolic blood pressure before nasotracheal intubation. 3. In patients with Ⅳ lidocatine, 1.5mg/kg before nasotracheal intubation, there was significant increase one minute after intubation compared with the systolic blood pressure before intubation. 4. There were the significant decrease of systolic blood pressure one minutes after nasotracheal intubation in patients with Ⅳ lidocaine, 1mg/kg and compared with the value of control group. 5. There were the significant decreases of systolic blood pressure after nasotracheal intubation in patients with Ⅳ lidocaine 1mg/kg one to these minutes after intubation compared with the values of control group.
