Abstract:
Objective To evaluate the effectiveness and accuracy of a domestic continuous non-invasive blood pressure (NIBP) device in monitoring intraoperative blood pressure.Methods Sixty patients of both sexes,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,undergoing elective surgery under general anesthesia,were included in the study.The invasive blood pressure (IBP) and NIBP were simultaneously measured in the radial artery.Systolic and diastolic blood pressure (SBP,DBP) was continuously recorded,and the paired data and data of waveform were collected.For paired data,the agreement was evaluated using Bland-Altman analyses between the two monitoring methods.For waveform data,Pearson linear correlate analysis was performed between the two monitoring methods.Results For paired data,the bias of NIBP value from IBP value were (-2.1±5.4) mmHg (95％ CI-3.5-0.7 mmHg) and (2.6±6.4) mmHg (95％ CI 1.0-4.3 mmHg) for SBP and DBP,respectively.The 95％ limit of agreement of bias between the two methods was-12.6-8.5 mmHg for SBP and-10.0-15.3 mmHg for DBP.For waveform data,the bias of NIBP value from IBP value were (-2.1±6.5) mmHg (95％ CI-3.7-0.4 mmHg) and (3.1±6.8) mmHg (95％ CI 1.3-4.8 mmHg) for SBP and DBP,respectively.The correlation coefficient between the two methods was O.82 for SBP and 0.88 for DBP,P＜0.01.Conclusion The effectiveness and accuracy of this domestic continuous NIBP monitoring device in monitoring intraoperative blood pressure is clinically acceptable.
