Confirmatory chest radiographs after central line placement: are they warranted?

This study was designed to determine the ability of physicians to predict complications associated with the placement of central venous access devices and to decide whether a confirmatory chest radiograph is warranted after placement.

Patients receiving central venous access on an inpatient and outpatient gynecologic oncology service were studied. Data were collected regarding patient demographics, patient history, procedural details of the placement, and the type of catheter used. The physician then predicted which patients had a reasonable potential for placement complications. All of the patients then underwent radiography, which was then compared with the original prediction.

Ninety-eight patients who had central venous access devices placed were included in the study. Eighty of the 81 central lines thought by the practitioner to have been placed without incident caused no significant complications; one individual in this group had a minor pneumothorax. Two of 17 patients predicted to have complications were noted to have a pneumothorax that required hospitalization. No patients in the low-risk group were hospitalized for a placement complication, whereas two hospitalizations occurred in the high-risk group.

Confirmatory chest radiographs may potentially be omitted in certain cases after line placement when experienced clinicians use good technique, good clinical judgment, and discrimination.
