目的:探讨新生儿胫后动脉与桡动脉有创血压监测值的相关性。方法:选择60例新生儿行有创血压监测,分别于同侧胫后动脉和桡动脉置管,连接带双通道压力监测模块的监护仪,持续监测胫后动脉和桡动脉有创血压值,待患儿处于安静状态,同一时间点每隔15 min记录1次胫后动脉与桡动脉的收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP),共10次,获得600对数据。结果:胫后动脉有创血压的SBP、MAP比桡动脉高(P<0.05),DBP比桡动脉低(P<0.05),胫后动脉与桡动脉有创血压监测值呈显著正相关(P<0.05)。结论:在桡动脉置管失败等特殊的情况下,可以直接采用胫后动脉有创血压监测获取相关血流动力学数据,为临床诊断、治疗提供准确的依据,但两者之间有一定的差异,在判断病情时应注意。
Objective: To investigate the correlation between tibiofemoral artery and radial artery blood pressure monitoring in neonates. Methods: Sixty newborn infants were selected for invasive blood pressure monitoring. The ipsilateral posterior tibial artery and radial artery were cannulated respectively. The monitor with dual channel pressure monitoring module was connected. The invasive tibial artery and radial artery blood pressure were continuously monitored. At the same time point, the SBP, DBP and MAP of the posterior tibial artery and radial artery were recorded once every 15 minutes for a total of 600 data. Results: The posterior tibial artery with invasive blood pressure SBP, MAP was higher than the radial artery (P <0.05), DBP was lower than the radial artery (P <0.05), posterior tibial artery and radial artery blood pressure monitoring was significantly positive (P <0.05). CONCLUSIONS: In the special case of unsuccessful radial artery catheterization, we can directly use the invasive blood pressure monitoring of posterior tibial artery to obtain the relevant hemodynamic data to provide an accurate basis for clinical diagnosis and treatment, but there is a certain Differences in the judgment of the disease should pay attention.
