ABSTRACT

Objective To investigate the reliability of Narcotrend for monitoring the depth of sedation [the observer's assessment of alterness/sedation(OAA/S) scale] with midazolam and correlation between the depth of sedation and Narcotrend index.Methods 0 ASA Ⅰ-Ⅱ status patients scheduled for elective lower limb operations underwent spinal anesthesia,who were given target-controlled infusion of midazolam.Target plasma concentration was 50ng/ ml at first and increased by 10 ng/ml each grade until OAA/S scale became 1 point.Each target concentration infusion was maintained for 5min.Observe the patient the OAA/S scale to be 5 points.If the operation was not over yet,regulated the appropriate depth of sedation until the end of operation.The Narcotrend index of different OAA/S scale and heart rate,mean arterial pressure,respiration were recorded.Results In the deepening or recovery phase of sedation,OAA/S scales were correlated with Narcotrend index (Spearman' s r =0.786,0.652,all P < 0.05).Conclusion Narcotrend is a good index to guide target controlled infusion of midazolam,the index is closely related with the depth of sedation of midazolam.

ABSTRACT

OBJECTIVE To observe and compare the application result of two kinds of chemical indicator(CI)card contained in high pressure-steam sterilization chemical monitoring testing package for providing correct credible evidence of supplying material in each batch after high pressure-steam sterilization and to avoid resource lost because of fault estimation.METHODS The chemical monitoring testing package was made according Sterilization Criteria published in 2002,with the 3M 1250 and 1243 CI cards and 1292 biology indicator(BI) to observe the results in tested package after sterilization.RESULTS The BI in chemical monitoring testing package was all qualified,the qualified rate of 1250 was 70%,while of 1243 was 100%.CONCLUSIONS If there is no BI for monitoring,1243 CI card should be chosen in high pressure-steam sterilization chemical monitoring testing package for supplying material in each batch after high pressure-steam sterilization which is not influenced by moisture and the contacted material and is easy to read and evaluate,the resource lost caused by fault estimation can be avoided.
