Bacteremia during double-contrast barium enema examination

Area of Science:

• Medical Imaging
• Infectious Disease
• Gastroenterology

Background:

• Double-contrast barium enema is a common diagnostic imaging procedure.
• Concerns exist regarding the potential for transient bacteremia during invasive procedures.
• The risk of bacteremia in patients with cardiac valvular disease is a significant clinical consideration.

Purpose of the Study:

• To determine the incidence of transient bacteremia following double-contrast barium enema examinations.
• To assess whether patients with cardiac valvular disease face an elevated risk of bacteremia during this procedure.

Main Methods:

• Prospective study involving 45 patients undergoing double-contrast barium enema.
• Blood cultures collected immediately before and at 5, 10, and 20 minutes post-procedure.
• Aerobic and anaerobic culture media used for all blood samples.

Main Results:

• Four positive cultures identified, yielding common skin contaminants.
• No bacteremia caused by enteric pathogens was detected.
• No significant difference in bacteremia incidence was observed based on cardiac valvular status.

Conclusions:

• Double-contrast barium enema examinations are associated with a low incidence of transient bacteremia.
• The presence of cardiac valvular disease does not appear to increase the risk of bacteremia during these examinations.
• Routine antibiotic prophylaxis may not be necessary for patients with cardiac valvular disease undergoing barium enema.
