Abstract:
There are several kinds of PICC tip positioning method in clinic at present,including body surface measurement, X-ray tip location, ultrasound guided assisted positioning and venous ECG. The limitations of former three methods were that the physical structure of the individual differences may affect the results of surface measurement accuracy; the differences of visual and subjective judgment may exist between different observers and the patient may easy to be affected by X-ray radiation; B ultrasound guidance assisted positioning can not show the whole process, and some of the central vein in the discount or too deep in the catheter tip can not be judged. The localization of the P wave in the center of the tube was observed by the technique of the intra cavity ECG localization to judge the position of the catheter tip, which can be positioned in a timely manner in order to reduce the risks caused by incorrect position of the catheter tip, avoid postoperative X-ray radiation and readjust the tube, reduce the cost of inspection. This study summarizes the PICC tip localization method, the principle, advantage, stability, influence factor and the method of improving the stability of the electrocardiogram.
