Clinical TrialStatistical analysis of blood pressure measurement errors by oscillometry during surgical operations.
Although a validated oscillometry sphygmomanometer satisfies the accuracy criteria of Advancement of Medical Instrumentation (AAMI), its long-term blood pressure (BP) measurement error during operations remains to be determined. We aim to (a) compare the error range throughout surgical operations with the accuracy criteria of AAMI, and (b) investigate the probabilities of occurrence of abnormal, large errors and clinically meaningful errors. ⋯ The SD of long-term BP measurement by our oscillometric method during operations exceeds AAMI accuracy criteria. And it is important to be aware of the abnormal large errors and clinically meaningful errors as their probabilities are rather significant. We analyze the possible cause of the major errors and deduce that similar errors may also happen with other oscillometric devices.

Comparative Study Clinical TrialContinuous noninvasive arterial pressure: assessment in older and high-risk patients under analgesic sedation.
To assess the role of continuous noninvasive arterial pressure (CNAP) in elderly, high-risk patients with pronounced variation in arterial pressure (AP) under analgesic sedation. ⋯ The agreement between the two techniques used in this study of elderly high-risk patients under analgesic sedation is similar to that found in studies performed under general anesthesia. The best agreement was detected in hypotensive periods.
