Clinical application of dexmedetomidine and sufentanil in ICU patients with mechanical ventilation / 中国生化药物杂志

ABSTRACT

Objective To observe and analyze the clinical effect of dexmedetomidine combined with sufentanil in the treatment of ICU mechanical ventilation. Methods 80 cases of critically ill patients treated by mechanical ventilation in our hospital ICU from February 2014 to March 2015 were randomly divided into study group and control group (n=40), the study group was treated with dexmedetomidine and sufentanil combined drug treatment, the control group was treated with sufentanil and midazolam combined drug treatment. The sedative effect and analgesic effect of the two groups were compared at different time points after the administration. Results At each time point after medication, there was no significant difference with the score of SAS between study group and control group; The BPS scores of respiratory compliance, upper limb and facial expression of the study group were lower than those of the control group, the difference was statistically significant; the incidence of adverse reaction in the study group was 7.5% (3/40), which was significantly lower than that of the control group 22.5% (9/40), the difference was statistically significant (P<0.05); There were no significant differences in MAP, SpO2 and HR between the two groups before treatment; After treatment, the indexes of MAP, SpO2 and HR in the two groups at different time points and after extubation were significantly different from those before treatment (P<0.05), The difference of MAP, SpO2 and HR between the two groups at each time point after treatment and after extubation were statistically significant (P<0.05). Conclusion The combination of dexmedetomidine and sufentanil for ICU mechanical ventilation has a good sedative and analgesic effect, and is worthy of clinical practice, and it is worthy of clinical practice.
