Accuracy of Infusion of Midazolam with Plasma Concentration as Target in Clinical Anesthesia / 中国药房

ABSTRACT

OBJECTIVE:To study the accuracy of infusion of Midazoloam with plasma concentration as target. METHODS:The parameters of Midazoloam obtained from our researches were inputted into target-controlled infusion(TCI) system with C language. The clinical anesthesia of 12 patients undergoing selective operations was completed with plasma concentration as target-controlled infusion. Predicted value of plasma concentration of Midazoloam was compared with measured value. Parameters of Midazoloam sample were calculated such as performance error(PE),absolute performance error(absPE),median performance error(MDPE),median absolute performance error(MDAPE),constancy error(CE),absolute constancy error(absCE),median constancy error(MDCE) and median absolute constancy error(MDACE). RESULTS:PE,absPE,MDPE and MDAPE of plasma concentration were -2.57%,14.16%,-3.28% and 15.34%,respectively. CE,absCE,MDCE and MDACE were 0.06%,1.42%,0.03% and 1.21%,respectively. The measured values were in indirect relationship with predicated values(r=0.986,P
