Bladder Point-of-Care Ultrasound: A Time Saver in the Pediatric Emergency Department.

BACKGROUND: Pediatric patients undergoing transabdominal pelvic ultrasound require a full bladder as an acoustic window. Patients are typically relied upon to subjectively identify bladder fullness, but inaccurate reporting often leads to delays in test results, diagnosis, and treatment. OBJECTIVES: Our aim was to objectively evaluate bladder fullness by comparing the height of the bladder to the height of the uterus on point-of-care ultrasound (POCUS). Our hypothesis was that this method would result in faster time to imaging and decrease emergency department length of stay (ED LOS). METHODS: Bladder fullness was assessed using POCUS every 30 min until the bladder was full. If the height of the bladder was equal to or greater than the height of the uterus in the sagittal view, the bladder was considered full. The POCUS group was compared with a control group that relied solely on patients' self-identified bladder fullness. RESULTS: Females aged 8-18 years old with pelvic pain in the pediatric ED were included in the study. Forty POCUS patients were compared with a control group of 105 patients. The POCUS group demonstrated a decrease in time to pelvic imaging by 38.7 min (95% confidence interval -59.2 to -18.2; p < 0.0001) and a decrease in LOS by 49.2 min (95% CI -89.7 to -8.61; p = 0.004). There was poor overall agreement on bladder fullness between patient's subjective sensation and POCUS (k = 0.04). CONCLUSION: POCUS to evaluate bladder fullness by comparing the height of the bladder with the height of the uterus reduces time to pelvic imaging and ED LOS.

Bioterrorism-related inhalational anthrax: can extrapolated adult guidelines be applied to a pediatric population?

OBJECTIVE: Since the 2001 anthrax attacks, an extensive body of literature has evolved, but there has been a limited focus on the management of pediatric-specific issues. We looked at the symptom complexes of all pediatric patients presenting to the emergency department of our hospital during this period and examined whether their presentations would likely allow current guidelines to be used as potential screening criteria to identify children infected with anthrax. METHODS: We retrospectively reviewed emergency department records of all adult and pediatric patients (up to the age of 21 years) at Inova Fairfax Hospital during this time, when a large, and at the time ill-defined, group in the Washington, DC, metropolitan area was at risk for pulmonary anthrax. Two cases of anthrax infection were identified at this hospital in exposed adult postal workers. Screening algorithms (described by Mayer et al. and Hupert et al.) were applied to adult and pediatric patients with the presence of fever (38 degrees C), tachycardia, or other symptoms compatible with pulmonary anthrax. Specifically, the usefulness of these guidelines as potential screening tools to identify possibly infected children was examined. RESULTS: Of 767 pediatric patients seen in the emergency department during the study period, 312 met criteria for review (41%; 95% CI: 37-44%). Four adult patients (0.4%; 95% CI: 0.1-0.9%) had at least five clinical symptoms, fever, and tachycardia; two of them had inhalational anthrax. No pediatric patient presented with five or more clinical symptoms. Twelve children (3.9%; 95% CI: 2-6.6%) presented with four clinical symptoms; five of the 12 had neither fever nor tachycardia. Children, particularly infants and toddlers, presented with nonspecific symptom complexes primarily limited to fever, vomiting, cough, and trouble breathing. CONCLUSIONS: Existing guidelines are likely to be unreliable as a screening tool for inhalational anthrax in children, largely because of the children's inability to adequately communicate a suggestive symptom complex.

Acute urinary retention in a 9-year-old child: an atypical presentation of acute appendicitis.

Acute urinary retention is unusual in childhood and when present is likely to have an identifiable cause. Although the evaluation is often performed by the urologic specialist after relief of the obstruction, it is imperative that some causes be identified in the Emergency Department. This is a case of a 9-year-old boy in acute urinary retention caused by a ruptured appendix with a periappendiceal abscess.
