Routine X-Ray Not Needed After US-Guided Central Line Insertion


Routine X-Ray Not Needed After US-Guided Central Line Insertion

Pneumothorax and catheter misplacement after ultrasound-guided central venous catheter (CVC)  insertion were rare, and the costs of a postprocedural chest X-ray (CXR) were exceedingly high, according to a study published in the CHEST journal. The study suggested that a routine postprocedural CXR is unnecessary and not a wise choice.

A routine chest radiograph (CXR) is recommended as a screening test after central venous catheter (CVC) insertion. Jason Chui and his associates conducted a study to assess the value of a routine postprocedural CXR in the era of ultrasound-guided CVC insertion.

The investigators performed a population-based retrospective cohort study to review the records of all adult patients who had a CVC inserted in the operating room and determined the incidence of pneumothorax and catheter misplacement after ultrasound-guided CVC insertion. The researchers then examined the potential risk factors associated with these complications and analyzed the cost to evaluate the economic impact. A total of 6,875 patients were included in the study.

Key study findings:

  • The overall incidence of pneumothorax and catheter misplacement was 0.33% and 1.91% respectively.
  • The site of catheterization was the major determinant of pneumothorax and catheter misplacement; left subclavian vein catheterization was the site at a higher risk for pneumothorax.
  • Catheterization sites other than the right internal jugular vein were at a higher risk for catheter misplacement. Expenditures on routine postprocedural CXR were the US $105,000 to $183,000 per year.

According to the authors, a routine post-procedural CXR is unnecessary and not a wise choice.

  1. Population studied, clinical setting, hospital set up make a huge difference in outcome. This study was performed in a tertiary healthcare centre with CVC line placements done in OR under US guidance in adult patients. Their population had a lower chances of line insertion related complications,
