Abstract:
Objective:To explore the application effect of improved fingertip localization guided vascular puncture method in radial artery blood sampling.Methods:Using the convenience sampling method, patients receiving radial artery blood sampling for blood gas analysis in Department of Respiratory and Critical Care Medicine of First Affiliated Hospital of Nanjing Medical University from August to November 2020 were selected as research objects. The 44 patients whose blood was collected from August to September were used as the control group, and 44 patients whose blood was collected from October to November were used as the experimental group. The control group used conventional arterial puncture to collect blood from the radial artery, while the experimental group used modified fingertip localization guided vascular puncture to collect blood from the radial artery. The success rate of first puncture, duration of puncture, pain score during puncture and incidence of immediate complications after puncture were compared between the two groups. The t test and χ 2 test were used for statistical analysis. Results:The first success rate of radial artery puncture of patients in the experimental group (81.82%) was higher than that in the control group (56.82%) . The puncture time in the experimental group was (34.600±2.442) s, which was lower than (39.156±2.785) s in the control group. The pain score of the experimental group was (3.750±0.315) , which was lower than (4.318±0.306) of the control group. All the differences were statistically significant ( P<0.05) . There were no immediate complications after puncture in the experimental group and 2 cases in the control group. There was no statistically significant difference between the two groups ( P>0.05) . Conclusions:The improved fingertip localization guided vascular puncture method can increase the success rate of the first radial artery puncture, shorten the puncture time and reduce the pain of patients.
