危重病人无创伤动脉血压监测的相关因素研究

目的在危重病人中,研究影响心电监护仪测量血压的相关因素.方法共45例病人,根据上臂周长分成3组,分别进行心电监护仪测量、听诊器法卧式血压计测量血压.结果在二者比较中,其差值是(-3.54±2.84)mmHg(收缩压)、(-4.82±1.33)mmHg(舒张压);82.34%的差值小于10mmHg,而有17.67%的差值大于10mmHg.使用强心剂亦对测量血压产生影响,而且,不同的袖带(即1组与2、3组)之间均存在差异.结论在危重病人中,虽然心电监护仪测量血压存在偏差,但是绝大多数的测量数据在临床上是能够接受的.

Research on Related Factors of Non-invasive Arterial Pressure Monitoring in Intensive Patients

Objective To evaluate the related factors of non-invasive arterial pressure monitoring in critical patients.Methods Fourty-five critical patients were categorized into there groups according to their upper-arm circumference.In each patient,we performed an electrocardiographic monitoring blood pressure measurement.Then,we used auscultator sphygmomanometer to measure blood pressure.Result There were difference between eletrocardiographic monitoring and auscultator sphygmomanometer blood pressure measurement.The blood pressure measurement in 45 patients,82.34% had a discrepancy of <10 mmHg,17.67% had a discrepancy of >10 mmHg.Conclusion The electrocardiographic monitoring blood pressure measurement was difference from auscultator sphygmomanometer blood pressure measurement,but most of all measurement were in the clinically acceptable range.
