| Objective:To investigate the clinical application of intracavitary electrocardiographic (EKG) guided peripheral inserted central catheter (PICC) tip location method.Methods:Totally 180 patients with lung cancer were randomly divided into control group (90 cases) and observation group (90 cases).Then the observation group were subdivided into observation group 1 and 2 by puncture sequence. Routine post-procedure chest X-ray was used to confirm the peripheral inserted central catheter tip location for patients in control group while EKG method was applied for patients in observation group. Post-procedure chest X-ray combined with EKG method was employed in observation group 1 to double confirm the catheter tip location. Chest X-ray was used in observation group 2 only when patients’P wave change was not observed. The catheter in place rate, operation time, PICC-related complication and patients’ satisfaction were measured and compared between control group and observation group, observation group 1 and observation group 2. The catheter in best place rate was compared between control group and observation group 1.Results:The operation time is statistically shorter (z=6.364, P=0.000), but the catheter in place rate and patients’satisfaction were statistically increased in observation group than in control group (χ2=7.745, P=0.005;63.34%/96.67%, P=0.000). The catheter in best place rate was lower in control group than in observation group 1(χ2=43.740, P=0.000). The cost and operation time in observation group 2 were both lower than in observation group 1 (χ2=9.0189, P=0.000; x2= 7.6202, P=0.000), but the patients’satisfaction has no statistically difference between the two groups (z=-1.719,P=0.086).There was no statistical difference in catheter-related complication between each groups (P>0.05).Conclusions:The EKG method is accuracy, safe and can effectively help the catheter in place as well as reduce the time from catheter insertion to infusion therapy. When P wave change can be clearly observed on EKG, routine post-procedure chest X-ray is unnecessary. |
