Rigid tracheobronchoscopy-induced bacteremia in the pediatric population.

OBJECTIVE: To assess the incidence of bacteremia following rigid tracheobronchoscopy in children to determine whether use of prophylactic antibiotics is warranted in pediatric patients at risk for perioperative endocarditis. DESIGN: Prospective nonrandomized clinical study. SETTING: Specialty care referral center. PATIENTS: Patients younger than 18 years undergoing diagnostic rigid tracheobronchoscopy for airway assessment. Twenty-five patients (14 boys and 11 girls) were enrolled. The mean age was 5.2 years (range, 10 months to 13 years). INTERVENTIONS: Blood samples for culture were obtained intraoperatively at 2 time intervals. The first culture was obtained after the induction of mask anesthesia prior to airway instrumentation; the second, within 5 minutes following the completion of tracheobronchoscopy. Blood cultures were performed under sterile technique and were placed into 20 mL of brain heart infusion broth. All cultures were incubated at 35 degrees C and observed for growth over a 14-day period. RESULTS: There were no documented cases of bacterial growth in blood cultures. All blood cultures, obtained before and after tracheobronchoscopy, were negative for bacterial growth after incubation for 14 days. Two culture bottles yielded contaminant organisms. CONCLUSIONS: Rigid tracheobronchoscopy in the pediatric population is a low-risk procedure for the development of bacteremia. This may bear on present guidelines regarding perioperative antibiotic prophylaxis for endocarditis in the high-risk population.

Treatment of aural foreign bodies in children.

OBJECTIVE: To determine the proper treatment of children and adolescents with foreign bodies of the external auditory canal (EAC). DESIGN: Retrospective case series. SETTING: Specialty care referral hospital. PATIENTS: All patients younger than 18 years of age who presented in the emergency ward or office setting with a foreign body of the EAC during a 5-year period. RESULTS: One hundred ninety-one patients with aural foreign bodies were identified. Age at presentation ranged from 10 months to 17 years with 141 patients (74%) younger than 8 years old. Twenty-seven different objects were encountered with pebbles, beads, insects, and plastic toys the most common. Fifty-seven (30%) of the patients required surgical removal of the aural foreign body under general anesthesia. CONCLUSION: Adequate immobilization and proper instrumentation allow the uncomplicated removal of many EAC foreign bodies in the pediatric population. The use of general anesthesia is preferred in very young children and in children of any age with aural foreign bodies whose contour, composition, or location predispose to traumatic removal in the ambulatory setting. Criteria for otolaryngologic referral and consideration of operative microscopic removal are outlined.
