A simple calculation formula for the insertion depth of catheter of the central venous access port in Chinese patients
Background: The catheter tip placed between the T6 and T7 vertebrae is recognized as an optimal position for the totally implantable venous access ports (TIVAPs). This study aimed to propose a simple formula for calculating the optimal insertion depth of the right internal jugular central venous cat...

| description | Background: The catheter tip placed between the T6 and T7 vertebrae is recognized as an optimal position for the totally implantable venous access ports (TIVAPs). This study aimed to propose a simple formula for calculating the optimal insertion depth of the right internal jugular central venous catheter (CVC) of TIVAP in Chinese patients. Methods: This was a prospective observational study. The medical records of 151 patients with TIVAPs placement were retrospectively analyzed. Patient's height and actual insertion depth of CVC were used to build a simple linear regression model. The Peres' formula was revised to better calculate the optimal insertion depth of the right internal jugular CVC of TIVAPs, accounting for population-specific anatomical variations observed in Chinese patients. A total of 158 patients scheduled for TIVAPs placement were prospectively recruited. The insertion depth of catheter was preoperatively determined according to the established formula, and postoperative chest X-ray was performed to determine the position of catheter tip. The rate of proper position of catheter (the catheter tip within T6 or T7 vertebrae) was calculated to assess the clinical feasibility and effectiveness of the new formula. Results: The proper position rate was 64.24 % (97/151) in the retrospective group. According to patients' height and insertion depth of CVC of these 97 cases with proper position, Peres' formula was revised to ‘insertion depth = 0.1∗height – 4 (cm)’. Based on insertion depth predicted by the new formula, the proper position rate in the prospective group reached 86.08 % (136/158). Conclusion: The simple formula for calculating the insertion depth of right internal jugular CVC of TIVAPs is clinically feasible for Chinese patients. |
