Inflationary noninvasive blood pressure (iNIBP) monitoring can determine BP in a shorter time compared to conventional deflationary NIBP (dNIBP) monitoring. We assessed the efficacy of iNIBP monitoring during induction of general anaesthesia and tracheal intubation, which can cause rapid changes in haemodynamics. Our study included 14 surgery patients receiving tracheal intubation under general anaesthesia. Blood pressure was continuously measured using iNIBP monitoring. We recorded the percentage of successful iNIBP monitoring (measurements made without switching to dNIBP mode) during anaesthesia induction. We obtained 326 BP-measurements from 14 patients. The iNIPB mode was able to perform 90.9% of the measurements during the induction of general anaesthesia. iNIBP could determine BP even during periods of high blood pressure variability (31.6% [interquartile range; 22–40]). Our results validate the utility of iNIBP monitoring during the induction period of general anaesthesia, despite the rapid haemodynamic changes.

AbstractBackground: A number of studies reveal that home blood pressure variability is associated with cardiovascular risk factors. However, we do not have a consensus regarding the variability index and the frequency of measurements.Objective: The aim of the study was to assess home blood pressure variability for a period of 7 consecutive days and 24-hour ambulatory blood pressure variability using the average real variability index and to test whether home blood pressure variability represents a suitable parameter for long-term monitoring of the hypertensive patients.Material and methods: A number of 31 hypertensive patients were included in the study, 8 male, 23 female, mean age 60.19±7.35 years. At the inclusion ambulatory blood pressure monitoring was performed, home blood pressure monitoring was carried out for 7 consecutive days with 2 measurements daily. We compared ambulatory blood pressure values, variability using paired t-test. We were looking for correlations between HBP values and cardiovascular risk factors.Results: Ambulatory versus home blood pressure derived mean blood pressure was 131.38±15.2 versus 131.93±8.25, p=0.81. Ambulatory derived variability was 10.65±2.05 versus home variability 10.56±4.83, p=0.91. Home versus ambulatory pulse pressure was 51.8± 9.06 mmHg vs. 54.9±11.9 mmHg, p=0.046. We found positive correlation between HBPV and home BP values, p=0.027, r2=0.1577, (CI: 0.04967 to 0.6588). Home, as well as ambulatory derived variability were positively correlated to age p=0.043, r2=0.1377 (CI: 0.01234 to 0.6451) versus p<0.0001, CI: 0.3870 to 0.8220, r2=0.4302.Conclusion: Assessment of home blood pressure monitoring and variability could represent a well-tolerated alternative for long-term follow-up of hypertension management.

Of the first 2000 incidents reported to the Australian Incident Monitoring Study, 1256 occurred in relation to general anaesthesia and 81 of the latter were first detected by blood pressure (BP) monitoring. A further 25 incidents not associated with general anaesthesia were first detected by blood pressure monitoring, giving a total of 106. In the monitor detection of incidents in relation to general anaesthesia, BP monitoring ranked fourth after oximetry, capnography and low pressure alarms. On the other hand, 38 incidents in which the problem was primarily one of significant change in BP were first detected by means other than the BP monitor (20 clinically, 12 by pulse oximetry and 6 by ECG). Early detection rates of hypotension were 60% for invasive methods, 40% for automated non-invasive (NIBP) devices and 30% for manual sphygmomanometry. There were 21 reports of BP monitor “failure”; the 11 of these which occurred with NIBPs involved unexplained false “low” or “high” readings and failure to detect profound hypotension, and led to considerable morbidity and at least one death. The 10 cases of invasive monitoring failure were predominantly due to mains power loss, hardware breakage or operator error. In a theoretical analysis of the 1256 GA incidents, it was considered that on its own, BP monitoring would have detected 919 (73%), but in the vast majority, by the time this detection has occurred, potential organ damage could not be excluded. It is recommended that BP be measured at regular intervals dictated by clinical requirements (usually at least every five minutes). BP monitoring should be supplemented by other modalities in accordance with the College of Anaesthetists guidelines and when immediate and reliable detection of change in BP is critical, invasive monitoring should be used.
