ABSTRACT

Objective To explore the application effect of sufentanil or dexmedetomidine on blind intubation in 88 patients with difficult airway .Methods Eighty eight cases of patients with difficult airways in our hospital were divided into treatment group and control group depending on different preoperative sedation .There were 44 cases in each group .Patients in the treatment group were treated with dexmedetomidine anesthesia treatment ,and patients in the control group were treated in clinical routine application of sufentanil anesthesia ,both groups were taken blind intubation after anesthesia treatment .The heart rate ,systolic arterial pressure , diastolic arterial pressure and respiratory rate of patients before anesthesia ,after anesthesia ,when the intubation tube reached uvu‐la ,epiglottis ,when the intubation finished and 5 minutes after the intubation were recorded .Cases of nausea ,dysphoria ,bucking and respiratory depression during the intubation were also recorded .Results From the induction of anesthesia to 5 min after intubation , the respiratory rate of the treatment group was higher than the control group (P<0 .05);the systolic blood pressure ,diastolic blood pressure and heart rate of treatment group were significantly lower than the control group since intubation tube arrive uvula until the completion of systolic (P<0 .05);The arterial oxygen pressure was (98 .52 ± 9 .18) mm Hg in the treatment group 5 min after intubation ,which was significantly higher than the control group which was (93 .46 ± 10 .81) mm Hg (P<0 .05);cases of nausea , dysphoria ,bucking and respiratory depression in the treatment group were significantly lower than that of control group(P<0 .05) , and the average intubation time of the treatment group were significantly shorter than that of control group (P<0 .05) .Conclusion Dexmedetomidine could effectively improve the condition of the patients with difficult airways ,achieve effective anesthesia ,reduce cardiovascular reactivity in patients ,and ensure the smooth progress of intubation for the difficult airway patients .
