Abstract

The invention discloses a method for predicting the PICC (Peripherally Inserted Central Catheter) catheterization length. The method comprises the following steps: step 1, before catheterization, measuring a vertical distance B from the lower edge of the inner end of a right clavicle on an X-ray chest normal position film to a vertebral body below a tracheal carina; 2, the patient is in a horizontal position, the puncture side arm extends outwards by 90 degrees, and the distance A from the puncture point to the right sternoclavicular joint is measured; 3, the implantation length L of the PICC is calculated according to the formula L = A + B-2 cm. The method for predicting the length of the PICC is simple and easy to implement, easy to operate clinically, high in accuracy and capable of ensuring that the tip of the catheter falls in the optimal region range. As data is derived from chest radiography and human body measurement, errors caused by human body differences in a traditional method are avoided, and the method has better adaptability (the method is still very effective when being applied to a humpback patient).

Description

technical field [0001] The invention relates to a method for predicting the length of PICC placement, in particular to a method for measuring and calculating the ideal length of PICC placement. Background technique [0002] Peripherally inserted central catheter (PICC) has been widely used clinically. It is recognized as a safe and reliable intravenous infusion route with less trauma during long-term intravenous infusion or periodic chemotherapy. The position of the catheter tip is critical for therapeutic efficacy. Accurately predicting the catheter length can improve the accuracy of PICC puncture and reduce the occurrence of catheter malposition. [0003] INS recommends that the best position of the PICC tip in the patient's body is the middle and lower 1 / 3 of the superior vena cava, 3-4 cm above the junction of the superior vena cava and the right atrium, and cannot enter the right atrium or right ventricle. However, in actual operation, foreign survey results show that...
