Study on Application of Intracavitary Electrocardiogram Combined with Ultrasound-guided Peripherally Inserted Central Venous Catheter for Tip Positioning
Objective:To explore the application of intracavitary electrocardiogram combined with ultrasound-guided peripherally inserted central venous catheter(PICC)tip positioning.Method:The clinical research subjects selected 90 patients who received PICC catheterization at the PICC outpatient department of Jiujiang NO.1 People's Hospital from October 2020 to October 2022,were divided into observation group and control group according to the random number table method,with 45 patients in each group.The control group received catheterization guided by intracavitary electroencephalography,while the observation group received catheterization guided by ultrasound PICC in combination with the control group.The success rate of puncture,PICC tip positioning,numeric rating scale(NRS)score,patient satisfaction and the occurrence of adverse reactions in two groups were observed.Result:The success rate of single catheterization in the observation group(88.89%)was significantly higher than that in the control group(68.89%),and the total catheterization success rate(97.78%)was higher than that of the control group(86.67%)(P＜0.05).Rate of PICC tip localization reaching the optimal position in the observation group(95.45%)was higher than that in the control group(76.92%)(P＜0.05).The NRS score of the observation group was better than that of the control group(P＜0.05).The overall satisfaction rate of the observation group(95.56%)was higher than that of the control group(66.67%)(P＜0.05).The total incidence of adverse reactions in the observation group(4.44%)was lower than that in the control group(20.00%)(P＜0.05).Conclusion:Adopting a combination of intracavitary electroencephalography and ultrasound-guided localization for patients undergoing PICC catheterization can improve the success rate of catheterization,increase the rate of achieving optimal PICC tip localization,and reduce patient pain;on the other hand,improving patient satisfaction and reducing the incidence of adverse reactions.
