Meta-analysis of efficacy and safety of sedative therapy with midazolam and dexmedetomidine/propofol in critically ill patients undergoing mechanical ventilation
OBJECTIVE To systematically evaluate the efficacy and safety of midazolam and dexmedetomidine/propofol for the sedation of critically ill patients undergoing mechanical ventilation,and to provide evidence-based reference for clinical treatment.METHODS Retrieved from PubMed,Embase,Web of Science,Cochrane Library,Clinical trials.gov,China Journal Full Text Database,Chinese Science and Technology Journal Database,Wanfang database and China Biomedical Literature Database,the data on the efficacy and safety of midazolam and dexmetomidine/propofol for the sedation of critically ill patients undergoing mechanical ventilation were collected from the establishment of the database to March 31,2023.After extracting data from clinical studies that met the inclusion criteria,the meta-analysis was conducted by using the RevMan 5.3 statistical software.RESULTS A total of 31 literature were included,with a total of 2 765 patients.Results of meta-analysis showed that the mechanical ventilation time[MD=14.13,95%CI(13.75,14.52),P＜0.000 01]and the length of hospitalization in the intensive care unit[MD=0.92,95%CI(0.54,1.30),P＜0.000 01]of patients in the midazolam group was longer than dexmedetomidine/propofol group.The incidence of bradycardia in midazolam group was lower dexmedetomidine/propofol group[OR=0.60,95%CI(0.41,0.90),P=0.01],but there was no statistically significant difference in the incidence of hypotension between the two groups[OR=0.69,95%CI(0.47,1.01),P=0.06].The incidence of delirium[OR=3.88,95%CI(2.74,5.49),P＜0.000 01],ventilator-associated pneumonia[OR=2.32,95%CI(1.19,4.51),P= 0.01],and respiratory depression[OR=5.70,95%CI(3.09,10.52),P＜0.000 01]in midazolam group were higher than dexmedetomidine/propofol group.CONCLUSIONS Compared with dexmedetomidine/propofol,midazolam increases patients'mechanical ventilation time and the length of hospitalization in the intensive care unit in terms of efficacy,and increases the risk of delirium and pulmonary complications in terms of safety,but has a smaller cardiovascular impact.
