A survey of changs in hemodynamic response to intubation of trachea by oral and nasal routes

For a patient under any treatment it is very important to maintain a stable carciovascular system (C.V.S) under anesthesia. The C.V.S can be disturbed due to many factors, and one of factor which can later the hemodynamic system of the patient is laryngoscopy and intubation. Hence the assesment of the variations in the blood pressure (BP) and heart rate (HR) of the patient during laryngoscopy and intubation is very important. Hypertension and tachycardia as a great disorders causing great problems. Such as cerebrel hemorrhagia and myocardial infection which are occurred during general anesthesia. Laryngoscopy and eddotracheal intubation is necessery for airway management prevention of the aspiration of gastric contents. The amount of blood pressure and heart rate is measured in 1, 3, 5 after laryngoscopy and intubation. 70 patients ASAI with the age of 16-55, undergon elective srugery and a general aneshtesia were selected. Some drug pre-medication and induction were the same in rate about all patients. 35 patient are intubated orally and the rest of them nasaly. The subjects were chosen among patients who did not have difficult intubation nad cardiovascular disorders. Before laryngoscopy and 1,3,5 minutes blood pressure and HR measured. According to outcoming results, blood pressure and HR increasing after laryngoscopy in both group (oral intubtion and nasal intubation). The increase of nasotracheal intubation was more than oral one remarkably. The difference would be meaningful according to statistic point (P<0.05). According to research finding the most amount of increase in the blood pressure and HR was related to the laryngoscopy and intubation. These changes can make problems for some cardiovascular patients. So it is suggested that all anesthesists should lessen the probable complication of patients under laryngoscopy a tracheal intubation by monitoring BP and HR.
