Application of cluster intervention in the intracavitary electrocardiogram positioning of three-position valve PICC patients

Abstract

Objective To explore the effects of cluster intervention on the intracavitary electrocardiogram (ECG) positioning of three-position valve peripherally inserted central catheter (PICC) in tumor patients. Methods The patients who had PICC for chemotherapy from October 2014 to January 2017 in the tumor ward of Beijing Hospital were selected by convenience sampling method. A total of 374 cases of vitro measurement combined with X-ray leading three-position valve PICC were assigned into the control group, and 320 cases of vitro measurement combined with intracavity ECG oriented and X-ray cluster intervention were assigned into the intervention group. The position accuracy of the PICC tip and the catheter heterotopia situation of the patients were analyzed. Results The position accuracy of PICC tip of the cluster intervention group was higher than that of the control group, and the catheter heterotopia cases of the cluster intervention group was lower than that of the control group. All the differences were statistically sigfinicant (P<0.01) . Conclusions The cluster intervention of vitriol measurement combined with intracavity ECG oriented and X-ray in cancer patients with indwelling three-position valve PICC can improve the catheter tip position accuracy, correct the internal jugular ectopic which cannot be found by B-ultrasound, and reduce the ectopic occurrence because of short catheter.
