This study was a prospective, multicenter, randomized controlled study. The study aimed to exploring the influence of PICC intra catheter guide wire or PICC conductive tip as intra luminal electrode on the positioning accuracy of catheter tip and exploring the influence of PICC intra catheter guide wire or PICC conductive tip as intra luminal electrode on catheterization complications.

| PICC | Device | Peripheral central venous catheterization (PICC) is mainly applied to patients with medium and long-term intravenous infusion, infusion of stimulant drugs and intermittent infusion of chemotherapy drugs. It is a catheterization technology to place PICC through peripheral veins and make its tip reach the central vein |
| Measure | Description | Time Frame |
|---|---|---|
| Accuracy of tip determination | IC-ECG method was used to place the tube, and X-ray was used to determine the accuracy of tip location after confirmation. If the two judgments are inconsistent, the third method, such as echocardiography, shall be used. The tip determination accuracy of IC-ECG localization method and X-ray localization method were calculated respectively.X-ray judgment standard: the reference standard is the first choice of the cardiac shadow method: not exceeding the highest protrusion on the left side of the cardiac shadow (tracheal protrusion method: 0-3cm below the tracheal protrusion); Secondary rib reading method: posterior 5-7 ribs. | Immediately after surgery |

| success rate of one catheterization |
one-time successful catheterization means that the tip of the catheter can be placed at the ideal position in one catheterization operation, without adjustment after X-ray confirmation. After catheterization, both groups of patients need to verify whether the tip is in the ideal position through X-ray, and whether the operation is successful also needs to be judged through X-ray, and the X-ray results need to be retained (random number, center code, initials, time). All results will be sent to the central laboratory for analysis and interpretation. |
| Immediately after surgery |
| rate of convenient | survey whether the operators think the operation is convenient through questionnaires made by ourselves. | Immediately after surgery |
| rate of unplanned extubation | Proportion of early removal due to complications | After the operation to 180 days |
| Retention duration | After the operation to 180 days |
| Medical costs resulting from complications | After the operation to 180 days |
