Objective: To investigate the application effect of location technique of endocaridal ECG at catheter tip of patient with catheter of peripherally inserted central catheter(PICC) during the period of wearing catheter. Methods: 116 patients with peripherally inserted central catheter(PICC) were enrolled into the research. And the location of endocaridal ECG were guided through saline water column under the condition without guiding wire. In these ECG, the results of 110 cases showed P wave was high, and results of 4 cases showed incisura of M shape, and results of 2 cases showed P wave was flatness. As the confirmed results of X-ray, the catheters of 2 patients with flat P wave were ectopic. Results: After endocaridal ECG was guided by using saline water column, the change of P wave could locate the tip location of patients with catheter of PICC, and its specificity was 98.2%. And the difference of P wave between guided endocaridal ECG and ECG of body surface was significant(t=22.194, P0.05). Conclusion: The catheter of PICC that observes the change of P wave by guiding endocaridal ECG can judge the location of the tip of catheter. And this operation is convenient, non-damage, and high specificity. Besides, it can decrease examination cost of patients, and enhance the safety of patient with catheter of endocaridal ECG. Therefore, its clinical application value is well.
