Major surgical procedures can alter intestinal microbiota and disrupt the intestinal barrier function, leaving the patient at risk for infection. Probiotics are defined as live microorganisms that confer a health benefit on the host when administered in adequate amounts. Although the efficacy of administering probiotics perioperatively to adults has been reported, the clinical significance of probiotics in children undergoing surgery is still unclear. This study provides a brief overview of our randomized controlled trial of preoperative probiotic administration to children, and discusses the relationship between probiotics and their effects in the perioperative period, particularly focusing on bacteremia.
