ABSTRACT
Objective:
To compare the correlation and differences between invasive blood pressure(IBP)and noninvasive blood pressure(NBP)monitoring at three different levels of systolic blood pressure(SBP), diastolic blood pressure(DBP)and mean arterial pressure(MAP)in elderly hypertensive patients with atherosclerosis of the extremities during perioperative anesthesia.Methods:
156 elderly patients were prospectively admitted to the Department of Vascular Surgery, Beijing Anzhen Hospital, Capital Medical University, for peripheral vascular stenosis interventions between December 2018 and December 2021.Their IBP and NBP were measured simultaneously during the perioperative anesthesia period.Then the correlation and consistency between IBP and NBP were analyzed via the Pearson correlation coefficient, Bland-Altman plots, and the receiver operating characteristic curve(ROC curve).Results:
A total of 156 elderly patients were enrolled, including 108 men(69.2%)and 48 women(30.8%), with a mean age of 72.2±7.6.Pearson correlation analysis revealed that there was a significant positive correlation between IBP and NBP.The correlation coefficient was 0.993 for invasive systolic blood pressure(ISBP)and non-invasive systolic blood pressure(NSBP), 0.808 for invasive diastolic blood pressure(IDBP)and non-invasive diastolic blood pressure(NDBP), and 0.853 for invasive mean arterial pressure(IMAP)and non-invasive mean arterial pressure(NMAP)( P<0.001 for all). Bland-Altman analysis showed that the mean deviation of ISBP and NSBP was(20.3±6.5)mmHg(95% CI 19.18-21.38)(1 mmHg=0.133 kPa), the mean deviation of IDBP and NDBP was(3.8±9.7)mmHg(95% CI 2.13-5.41), and the mean deviation of IMAP and NMAP was(12.7±11.0)mmHg(95% CI 10.83-14.55). The correlation coefficient of ISBP-NSBP deviation with ISBP was 0.856, the correlation coefficient of IDBP-NDBP deviation with IDBP was 0.206, and the correlation coefficient of IMAP-NMAP deviation with IMAP was 0.583( P<0.05 for all). When ISBP≥137 mmHg, the sensitivity of an ISBP-NSBP deviation ≥20 mmHg was 96.3%, the specificity was 96.4%, and the area under the ROC curve was 0.970(95% CI 0.934-1.000). When ISBP≥158 mmHg, the sensitivity and specificity of a predicted ISBP-NSBP deviation≥25 mmHg were 97.4% and 78.8%, respectively, and the area under the ROC curve was 0.876(95% CI 0.820-0.933); When ISBP≥208 mmHg, the sensitivity and specificity of a predicted ISBP-NSBP deviation≥30 mmHg were 100% and 98.5%, respectively, and the area under the ROC curve was 0.985(95% CI 0.964-1.000).Conclusions:
There is a good agreement between IBP and NBP in elderly hypertensive patients with peripheral atherosclerosis during perioperative anesthesia.The magnitude of the deviation between the two is significantly and positively correlated with the level of blood pressure, suggesting that we should appropriately choose the method of blood pressure measurement in the perioperative period to correctly evaluate the blood pressure of these elderly patients.
