远洋舰船上无创血压测量仪的应用研究

摘要

目的：比较远洋舰船环境下3种无创血压测量仪所测血压值的差异，为远洋舰船环境下无创血压测量仪的选择提供依据。方法在某远洋舰船上对50名船员在启航前及任务海区航行中分别采用台式水银血压计（ A组）、弹簧表式血压计（B组）及多功能监护仪（C组）连续测量血压3次，记录收缩压（SBP）及舒张压（DBP），统计分析3种测量仪启航前后血压均值差异性以及3次测量SBP相差＞5 mmHg占总人数百分比。结果 A组启航前后所测SBP均值比较差异有统计学意义（P＜0．01），DBP均值比较差异无统计学意义（P＞0．05）；而B、C组启航前后所测SBP及DBP均值比较差异均无统计学意义（P＞0．05）。3次SBP及DBP相差＞5 mmHg占总人数百分比，启航前A、B、C组分别为6％和4％、10％和6％、42％和23％，航行中分别为36％和19％、16％和10％、46％和27％。结论远洋舰船航行中对3种血压计测量准确性及可重复性均有影响，对水银血压计影响尤为明显。建议远洋舰船航行中使用近期校正的弹簧表式血压计作为首选。%Objective To compare the differences in the blood pressure values by 3 types of noninvasive blood pressure meas-urement instruments , so as to provide evidence for the selection of noninvasive blood pressure measurement instruments applied to the o -cean-going ship.Methods The blood pressure values of 50 afloat personnel were measured 3 times consecutively with desktop mercuri-al sphygmomanometer (Group A), spring type sphygmomanometer (Group B) and multifunctional monitor (Group C), before and dur-ing deployment.Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were detected and recorded.Then, differences in the mean blood pressure values detected both before and after deployment at sea and the percentage of the 3 detected mean SBP values (>5 mmHg) were analyzed statistically .Results There were significant statistical differences in the mean SBP values of group A de-tected before and after deployment (P <0.001), but no statistical significance could be noted in the mean DBP values , when compar-isons were made between the pre and post deployment values (P>0.05).Nevertheless, there were no significant statistical differences in the mean SBP and DBP values of group B and group C detected before and after deployment (P>0.05).The percentage of the 3 SBP and DBP data (>5 mmHg) detected before deployment was 6%/4%, 10%/6%and 42%/23%in groups A, B and C, and that of the SBP and DBP data detected during deployment was 36%/19%,16%/10%and 46%/27%, respectively .Conclusion Ship de-ployment had certain effects on the accuracy and repeatability of the 3 types of blood pressure measurement instruments , the mercurial sphygmomanometer in particular .It was suggested that the spring sphygmomanometer calibrated just recently was the first choice of blood pressure measurement instrument applied to the ocean-going ship.
