摘　　要：目的探讨不同血压范围内的有创足背动脉收缩压与无创肱动脉收缩压的关系。方法选取上海市中西医结合医院2012年6月—2013年5月行消化道肿瘤切除术的50例患者,选用右侧肱动脉测量无创血压(NIBP),选用足背动脉测量有创血压(ABP)。所有患者均于静脉吸入复合麻醉下进行手术,记录患者足背动脉穿刺诱导后1min(T1)、气管插管瞬间(T2)、气管插管后2min(T3)、手术切皮时(T4)各时间点的ABP和与之对应的NIBP,取值均为收缩压。以ABP 111mmHg(1mmHg=0.133kPa)为临界值,对不同ABP范围内各时间点的ABP与NIBP之间的差异进行比较。结果当ABP<111mmHg时,各时间点的ABP均高于NIBP,但仅T3时间点的差异有统计学意义(P<0.01),且仅T3时间点的APB与NIBP呈正相关(r=0.55,P<0.05)。当ABP≥111mmHg时,各时间点的ABP均显著高于NIBP(P值均<0.01),且ABP与NIBP均呈正相关(r=0.85、0.86、0.61、0.80,P值均<0.05)。结论当行消化道肿瘤切除术患者足背动脉ABP≥111mmHg时,ABP显著高于NIBP且两者呈正相关;而当ABP<111mmHg时,ABP并不低于NIBP。Objective To investigate the relationship between non-invasive blood pressure （NIBP） and arterial blood pressure （ABP） when ABP was in different ranges. Methods A self-control study was conducted on 50 patients undergoing gastrointestinal tumor operation in Shanghai TOM-Integrated Hospital from June 2012 to May 2013. The blood pressure of right brachial artery was measured as NIBP and the blood pressure of dorsalis pedis artery were measured as ABP simultaneously. Venous-inhalation combined anesthesia was performed in all patients. NIBP and ABP were recorded 1 min after induction （T1）, at the moment of tracheal intubation （T2）, 2 min after intubation （T3） and at the moment of skin incision （T4）. The values of NIBP and ABP were all systolic pressure. Systolic pressure of 111 mmHg （1 mmHg= 0. 133 kPa） was chosen as cut-off point, and the differences between ABP and NIBP at various time points were compared. Results When ABP was less than 111 mmHg, ABP was higher than NIBP at each time point, while there was significant difference between ABP and NIBP only at T3 （ P〈0.01 ） ; and only at T3, NIBP was found positively correlated with ABP （ r = 0,55, P〈0.05）. When ABP was 111 mmHg and more, ABP was significantly higher than NIBP at each time point （all P〈0.01） ; and NIBP was found positively correlated with ABP at all time points （r = 0.85, 0.86, 0.61, 0.80, all P〈0.05）. Conclusion ABP of dorsalis pedis artery is significantly higher than NIBP when ABP 〈 111 mmHg and the two were positively correlated, while ABP is not lower than NIBP when ABP〈111 mmHg in patients undergoing gastrointestinal tumor operation.
