Application Of Different Arterial Catheters To Monitor Blood Pressure In ICU Patients

Objective To explore the differences and correlations between invasive blood pressure and non-invasive blood pressure results by different arterial catheters,and providing a reference to guide clinical rescue and treatment more accurately by using effective blood pressure,improve the success rate of arterial puncture,prolong the indwelling time,and reduce the occurrence of various complications.Methods A total of 100 patients admitted in the Department of ICU,Second Affiliated Hospital of Integrated Traditional Chinese and Western Medicine,Hunan University of Traditional Chinese Medicine from February 2017 to February 2018 were selected as subjects.According to the random number table method,divided the patients randomly into groups A(the radial arterial group)and group B(the dorsal artery of the foot of the foot).In group A,monitoring blood pressure by radial artery puncture,and in group B,monitoring blood pressure by the dorsal artery of the foot of the foot puncture,both of which measured non-invasive blood pressure at the iliac artery of the puncture side and recorded 24-hour blood pressure values,one-time puncture success rate,indwelling time,and the complications after catheter placement.SPSS17.0 software was used for statistical analysis of data.Results 1.The difference between invasive blood pressure and non-invasive blood pressure: There was statistically significant difference between invasive and non-invasive SBP and DBP in arterial puncture monitoring between A and B groups(P<0.001);2.Correlation between invasive blood pressure and non-invasive blood pressure: Scatter plots and Pearson correlation analysis results suggest that there is a high linear correlation between invasive blood pressure and non-invasive blood pressure(A group radial artery SBP,DBP: r=0.915,r=0.903 P<0.001;Group B dorsal artery of the foot SBP,DBP: r=0.818,r=0.892,P<0.001);3.Comparison of one-time puncture success rate: The success rate of one-time puncture in the radial artery group was 62%,and the one-time puncture rate in the dorsal artery of the foot group was 83%.There was a significant difference between the two groups(P<0.05);4.Complications caused by arterial puncture(hematoma,obstruction,and prolapse):The complications(hematoma,obstruction,and prolapse)caused by radial artery puncture and dorsal artery of the foot puncture were not statistically significant(P>0.05);5.Comparison of indwelling time: Radial artery puncture and dorsal artery of the foot puncture were statistically significant at the time of indwelling(1~2d,3~ 5d,more than 5d)(P<0.05),and both were statistically significant at the time of 1~ 2 days(P<0.05).The mean of radial artery indwelling was 3.21±1.16,and the mean of dorsal artery of the foot indwelling was 3.95±1.25;Conclusions 1.Invasive blood pressure and non-invasive blood pressure monitoring can not replace each other in blood pressure monitoring of ICU patients,priority should be given to invasive blood pressure monitoring;2.The monitoring of invasive blood pressure by radial artery puncture can reflect more accurately the blood pressure level of the patient;3.The success rate of disposable puncture through the dorsal artery of the foot is higher,the retention time is longer,and the patient's pain is even smaller.
