著者选择33名麻醉中患者,在一侧上臂桡动脉留置22号导管,测定连续动脉压(DI),同时用振动法(OS)和听诊法(AU)测量同侧血压,并进行统计学处理。结果表明,在测定方法上,收缩压相关系数DI与OS为0.86、DI与AU为0.84、OS与AU为0.95OS与AU的相关系数较其他两者高(P<0.005)。舒张压的相关系数分别为0.78、0.75及0.85,OS与AU比其他两组同样增高(P<0.005)。收缩压平均差(MD),在低血压范围内,DI比OS、AU明显降低,相反,在高血压范围DI比其他两者明显
The authors selected 33 patients under anesthesia, on the side of the upper arm radial artery catheter No. 22, determination of continuous arterial pressure (DI), while the vibration method (OS) and auscultatory (AU) measurement of ipsilateral blood pressure and statistical analysis . The results showed that the correlation coefficient of systolic blood pressure (DI) and OS was 0.86, DI and AU were 0.84, OS and AU were 0.95OS and AU were higher than those of the other two methods (P <0.005). The correlation coefficients of diastolic blood pressure were 0.78, 0.75 and 0.85, respectively. OS and AU were also higher than those of the other two groups (P <0.005). Mean systolic blood pressure (MD) was lower in DI than in OS and AU in the hypotensive range, whereas DI was significantly higher in the hypertensive range than in the other two
