Height-based formulas for predicting intravascular length of tunnelled neck central venous catheter in paediatric population

This retrospective study of 124 pediatric patients develops height-based formulas to predict optimal intravascular length for tunneled neck central venous catheters, achieving 70-80% accuracy within 1 cm. The formulas aim to reduce radiation exposure during CVC placement by minimizing fluoroscopy time needed for positioning confirmation.
