Emergency Bedside Ultrasound for Pediatric Soft Tissue Infections
Emergency Bedside Ultrasound for the Evaluation of Soft Tissue Infections in the Pediatric Emergency Department
Studie Overzicht
Gedetailleerde beschrijving
Skin and soft tissue infections, particularly abscesses caused by community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) are a growing public health problem. The treatment of a skin abscess usually requires incision and drainage or needle aspiration. In addition to providing definitive therapy, appropriate drainage can allow for organism identification and antibiotic susceptibility testing should antibiotics be utilized. A skin cellulitis, which is treated with systemic antibiotics and supportive care alone, may be hard to distinguish from an abscess, as both have similar clinical features. Therefore, as the presence or absence of purulent material may be difficult to determine, children may undergo an unnecessary drainage procedure. If drainage is avoided, the patient may require a subsequent ED visit if the diagnosis is missed on initial examination. This can lead to worsened clinical outcome, an extra financial burden for the family, and added emotional distress for the patient.
Bedside emergency ultrasound (EUS), which has been used since the mid-1980s is being used in adults to detect fluid collections such as soft tissue abscesses. Studies in adult patients have shown that EUS adds useful information to the history and physical examination and may even alter physicians' clinical impressions and management of patients. Currently, it is not known whether children represent a different population for EUS than adults and how EUS would perform in the pediatric outpatient setting. With improved diagnosis of soft tissue infections, better epidemiologic data about organism prevalence, improved and more prompt treatment, and more appropriate use of antibiotic therapy can be done.
To date, no study exists evaluating its utility specifically for the evaluation of soft tissue infections in pediatric patients. The goal of this study is to evaluate the test characteristics of EUS in pediatric patients presenting with evidence of soft tissue infection.

Sensitivity and Specificity of Bedside Emergency Ultrasound When Added to the Clinical Examination Compared With Clinical Examination Alone.
Tijdsspanne: 18 mos
|
The sensitivity and specificity of clinical examination with the addition of bedside emergency ultrasound will be compared against that of clinical examination alone.The number of lesions determined to actually have a drainable fluid collection will serve as the denominator in the calculation of sensitivity, and the number of lesions correctly identified as having a drainable fluid collection by clinical exam plus ultrasound and clinical exam alone, respectively, will serve as the numerator.The number of lesions determined to not have a drainable fluid collection will serve as the denominator in the calculation of specificity, and the number of lesions correctly identified as not having a drainable fluid collection by clinical exam plus ultrasound and clinical exam alone, respectively, will serve as the numerator.
Significance will be defined as a 95% confidence interval surrounding the differences between the two groups for sensitivity and specificity that does not include 0.
