Knowledge and Practices Regarding Prevention of Central Venous Catheter Removal-Associated Air Embolism: A Survey of Nonintensive Care Unit Medical and Nursing Staff.

INTRODUCTION

Air embolism is a potentially serious complication of central venous catheter (CVC) use. While CVC insertion is usually performed by a trained specialist, extraction is frequently the responsibility of junior staff members. This complication can be easily prevented by following several simple measures described in common guidelines.

AIM: We conducted a single-center survey to assess knowledge and practices concerning the prevention of air embolism associated with CVC removal among healthcare workers from nonintensive care units.

METHODS

The correct answers to the questionnaire were determined according to best-practice recommendations for CVC removal. Based on a comparison of the total sum of correct answers between the categories of groups, factors that predicted the level of knowledge were identified using an independent sample t test.

RESULTS

Of the 156 respondents, one-third were unfamiliar with air embolism as a complication of CVC extraction. Almost 80% were unaware of the existence of a CVC removal protocol. Almost half of respondents did not follow guidelines regarding patient position when removing a CVC, 72% did not ask the patient to perform the Valsalva maneuver during the procedure, and 54% did not ask the patient to remain supine after the procedure. Adherence to the protocol was correlated with professional experience, with a lower level among those with experience of less than 1 year and, particularly, among interns.

CONCLUSIONS

Our survey revealed inappropriately low awareness of CVC removal-associated air embolism risk and low familiarity with CVC removal best-practice recommendations among nonintensive care unit healthcare workers. Staff members with experience of less than 1 year, including interns, were found to have a lower level of knowledge. These findings emphasize the importance of development and distribution an internal hospital protocol and the integration of educational intervention into a preliminary internship program.
