Abstract:
Objective:To observe the effect of different endotracheal tube cuff pressure on cardiovascular response of patients , who underwent endotracheal intubation of general anesthesia ,during anesthesia induction .Methods:A total of 40 patients ,who were scheduled to undergo gynecologic surgery under general anesthesia and classified as classⅠ to Ⅱ according to American Society of Anesthesiologists(ASA) criteria ,were enrolled and randomly divided into high pressure group(cuff pressure 50 mmHg) and low pressure group(cuff pressure 30 mmHg) .Both two groups were intravenously given sufentanil 0 .5 μg/kg and propofol 2 .5 mg/kg in turn .Upon the patients losing consciousness ,succinylcholine 2 mg/kg was injected intravenously for induction ,and then intubation was conducted .Systolic blood pressure(SBP) ,diastolic blood pressure(DBP) and heart rate (HR) were recorded ,before anesthesia induction(baseline) ,after induction ,and at 1 ,2 and 3 min after intubation ,and the rate‐pressure product(RPP) was calculated .Results:There was no statistically significant difference between the two groups in patients’ age ,body weight ,height ,ASA classification(P>0 .05) .The difference between the two groups in patients’ blood pressure ,HR and RPP before anesthesia induction , showed no statistical significance ( P> 0 .05 ) .At 1 and 2 min after intubation ,the SBP and DBP in high pressure group were significantly higher than those in low pressure group(P<0 .05) .And at 1 ,2 and 3 min after intubation ,RPP in high pressure group were significantly higher than those in low pressure group(P<0 .01) .Conclusions:To control the cuff pressure of endotracheal tube has certaln effect on relieving the cardiovascular response during endotracheal intubation of general anesthesia .
