Application of intracavitary electrocardiogram in the tip positioning of peripherally inserted central catheter and its influence on the complications of PICC in patients with gastric cancer undergoing chemotherapy
Objective:To analyze the application of intracavitary electrocardiogram(ECG)in the tip position-ing of the peripherally inserted central catheter(PICC)and its influence on the complications of PICC in gastric cancer patients undergoing chemotherapy.Methods:In this study,300 patients with gastric cancer undergoing chemotherapy admitted to Hainan Hospital of Chinese PLA General Hospital from March 2018 to January 2020 were included and divided into the study and the control group by random number table method.The puncture points of the PICC catheter in the control group were located by X-ray,and those in the study group were located under the guidance of intracavitary ECG.The bleed-ing volume during puncturing,the complications of PICC catheterization,the one-time successful and failure rates of puncturing,the specific location of the catheter tip,and the time and cost of PICC posi-tioning were compared between the two groups.Results:The bleeding volume during puncturing in the study group was lower than that in the control group(P<0.05).The total incidence of catheteriza-tion complications in the study group(2.67%,4/150)was lower than that in the control group(16.67%,25/150)(P<0.05).The successful rate of puncturing under the guidance of intracavitary electrocardiogram was higher than that of the control group(P<0.05),while the failure rate of punc-turing was lower(P<0.05).The proportion of the best tip position in the study group was higher than that in the control group(P<0.05).The time and cost of PICC placement in the study group were ob-viously lower than those in the control group(P<0.05).Conclusion:Applying intracavity ECG in PICC catheterization can increase the successful puncture rate,reduce the incidence of PICC complica-tions,and reduce the time and cost for patients with gastric cancer undergoing chemotherapy.
