Evaluation of Hypertrophic Pyloric Stenosis by Pediatric Emergency Physician Sonography

OBJECTIVES The objective was to evaluate the accuracy of pediatric emergency physician (EP) sonography for infants with suspected hypertrophic pyloric stenosis (HPS). METHODS This was a prospective observational pilot study in an urban academic pediatric emergency department (PED). Patients were selected if the treating physician ordered an ultrasound (US) in the department of radiology for the evaluation of suspected HPS. RESULTS Sixty-seven patients were enrolled from August 2009 through April 2012. When identifying the pylorus, pediatric EPs correctly identified all 10 positive cases, with a sensitivity of 100% (95% confidence interval [CI] = 62% to 100%) and specificity of 100% (95% CI = 92% to 100%). There was no statistical difference between the measurements obtained by pediatric EPs and radiology staff for pyloric muscle width or length (p = 0.5 and p = 0.79, respectively). CONCLUSIONS Trained pediatric EPs can accurately assess the pylorus with US in the evaluation of HPS with good specificity.

Evaluation of acute appendicitis by pediatric emergency physician sonography.

STUDY OBJECTIVE We investigate the accuracy of pediatric emergency physician sonography for acute appendicitis in children. METHODS We prospectively enrolled children requiring surgical or radiology consultation for suspected acute appendicitis at an urban pediatric emergency department. Pediatric emergency physicians performed focused right lower-quadrant sonography after didactics and hands-on training with a structured scanning algorithm, including the graded-compression technique. We compared their sonographic interpretations with clinical and radiologic findings, as well as clinical outcomes as defined by follow-up or pathologic findings. RESULTS Thirteen pediatric emergency medicine sonographers performed 264 ultrasonographic studies, including 85 (32%) in children with pathology-verified appendicitis. Bedside sonography had a sensitivity of 85% (95% confidence interval [CI] 75% to 95%), specificity of 93% (95% CI 85% to 100%), positive likelihood ratio of 11.7 (95% CI 6.9 to 20), and negative likelihood ratio of 0.17 (95% CI 0.1 to 0.28). CONCLUSION With focused ultrasonographic training, pediatric emergency physicians can diagnose acute appendicitis with substantial accuracy.

Ultrasound-Guided Procedures in the Emergency Department—Diagnostic and Therapeutic Asset

Bedside ultrasound is an extremely valuable and rapidly accessible diagnostic and therapeutic modality in potentially life- and limb-threatening situations in the emergency department. In this report, the authors discuss the role of ultrasound in quick assessment of pathologic conditions and its use to aid in diagnostic and therapeutic interventions.

Point-of-Care Ultrasonography by Pediatric Emergency Physicians

Point-of-care ultrasonography is increasingly being used to facilitate accurate and timely diagnoses and to guide procedures. It is important for pediatric emergency physicians caring for patients in the emergency department to receive adequate and continued point-of-care ultrasonography training for those indications used in their practice setting. Emergency departments should have credentialing and quality assurance programs. Pediatric emergency medicine fellowships should provide appropriate training to physician trainees. Hospitals should provide privileges to physicians who demonstrate competency in point-of-care ultrasonography. Ongoing research will provide the necessary measures to define the optimal training and competency assessment standards. Requirements for credentialing and hospital privileges will vary and will be specific to individual departments and hospitals. As more physicians are trained and more research is completed, there should be one national standard for credentialing and privileging in point-of-care ultrasonography for pediatric emergency physicians.

Implementing routine HIV screening in an urban pediatric emergency department.

Objective In 2006, the Centers for Disease Control and Prevention recommended that all outpatient health care settings offer routine, opt-out HIV screening for patients aged 13 to 64 years, except where the prevalence of undiagnosed HIV infection is known to be less than 0.1%. Most emergency departments (EDs) lack routine HIV screening. The objective of this investigation was to describe the results of the implementation of routine, nontargeted opt-in HIV screening for patients aged 13 to 20 years in an urban pediatric ED (PED) in a city in which 1 of 30 residents has HIV/AIDS. Methods This was a retrospective chart review from an urban, academic PED. The implementation of routine HIV screening in the ED was funded by the New Jersey Department of Health and Senior Services and planned independently of the study investigator. Patients aged 13 to 64 years were offered HIV screening by nursing staff, physicians, and/or HIV counselors. Patients who accepted were screened with rapid HIV fingerstick testing performed via Clearview HIV 1/2 STAT-PAK by HIV counselors as per the New Jersey Department of Health and Senior Services protocol. Data collected by the study investigator were done by chart review from October through December 2009, the first 3 months after implementation of routine HIV screening. Data were collected from patients aged 13 to 20 years presenting to the PED. Primary outcomes measured included the proportion of patients offered and accepted screening, newly diagnosed HIV cases, and the rate of linking newly diagnosed HIV patients to treatment. Demographic data collected included patient age, sex, and ethnicity. Results from the first 3 months of routine, nontargeted screening were compared with the HIV screening results of October through December 2008, during which time rapid HIV screening was provided to patients in the ED based on clinical indication. Patients who were not offered testing or who refused testing were measured by forms that were placed in every chart and collected by physicians. Emergency department census data were queried to identify the total number of patients seen in the ED within age range and time frame studied. Results Three hundred (11%) of the 2645 patients aged 13 to 20 years were offered routine HIV screening in the PED from October through December 2009. Two hundred twenty-four patients (74%) accepted HIV testing. No new cases of HIV were identified. There was an increase in acceptance of HIV testing that correlated with increasing age (P < 0.05). There was no significant difference between male and female acceptance rates (P < 0.05). Eleven (4.9%) of the patients accepting testing did not have testing performed because of unavailability of the counselor and/or the patient could not wait. Review of HIV testing performed in the PED from October through December 2008 showed 39 patients aged 13 to 20 years were tested. Routine testing increased the number of patients tested by 446%. Conclusions Pediatric patients in this urban setting are very accepting of HIV testing. HIV screening is increased when routine screening is offered.

Does the use of bedside pelvic ultrasound decrease length of stay in the emergency department

Objectives Diagnostic ultrasounds by emergency medicine (EM) and pediatric emergency medicine (PEM) physicians have increased because of ultrasonography training during residency and fellowship. The availability of ultrasound in radiology departments is limited or difficult to obtain especially during nighttime hours. Studies have shown that EM physicians can accurately perform goal-directed ultrasound after appropriate training. The goal of this study was to compare the length of stay for patients receiving an ultrasound to confirm intrauterine pregnancies. The hypothesis of this study is that a bedside ultrasound by a trained EM/PEM physician can reduce length of stay in the emergency department (ED) by 1 hour. Methods This was a case cohort retrospective review for patients aged 13 to 21 years who received pelvic ultrasounds in the ED during 2007. Each patient was placed into 1 of 2 groups. Group 1 received bedside ultrasounds done by institutionally credentialed EM/PEM attending physicians. Group 2 received radiology department ultrasound only. Each group had subanalysis done including chief complaint, time of presentation, time to completion of ultrasound, length of stay, diagnosis, and disposition. Daytime was defined as presentation between 7 AM and 9 PM when radiology ultrasound technologists were routinely available. Results We studied 330 patients, with 244 patients (74%) in the bedside ultrasound group. The demographics of both groups showed no difference in age, presenting complaints, discharge diagnoses, and ultimate disposition. Group 1 had a significant reduction (P < 0.001) in time to complete the ultrasound compared with group 2 (mean, 82 minutes [range, 1–901 minutes] vs 149 minutes [range, 7–506 minutes]) and length of stay (142 [16–2268] vs 230 [16–844]). Of those presenting during the day (66%), group 1 showed a significant reduction in length of stay (P < 0.001) compared with group 2 (220 [21–951] vs 357 [156–844]). Of those who presented at night (34%), group 1 showed a significant reduction in length of stay (P < 0.002) compared with group 2 (270 [16–2268] vs 326 [127–691]). Conclusions The use of ED bedside ultrasound by trained EM/PEM physicians produced a significant reduction in length of stay in the ED, regardless of radiology ultrasound technologist availability.

Role of urine drug screening in the medical clearance of pediatric psychiatric patients: is there one?

Objectives Our primary objective was to investigate whether urine drug screen (UDS) results affected the medical management of pediatric psychiatric patients presenting to the pediatric emergency department (ED) for psychiatric evaluation and whether it affected the final disposition of these patients. Methods This was a retrospective chart review of patients who presented to an urban pediatric ED in Newark, NJ, with psychiatric or behavior problems for medical clearance before psychiatric evaluation between June 3, 2008, and June 3, 2009. Inclusion criteria were any patient between the ages of 0 to 20 years who presented to the pediatric ED and had a UDS performed. Exclusion criteria were if the UDS was obtained for a primary medical workup such as altered mental status, known or admitted overdose, or accidental ingestions, or no psychiatric consultation was made from the ED. Abstracted descriptive data include patient’s age, sex, race, and insurance status. Visit-specific data include patient’s reason for visit, results of the UDS, psychiatric diagnosis if any, history of substance abuse if any, and management decisions other than psychiatric evaluation after medical clearance. Results A total of 875 charts were identified from laboratory records; 539 of those patients presented to the pediatric ED for psychiatric evaluation. A total of 62 patients had at least 1 substance detected on the UDS and were referred to psychiatry. All of the patients who had presented for psychiatric evaluation, including those with a positive result on the UDS, were medically cleared with no documented change in management or medical intervention in the pediatric ED. Conclusions Obtaining a UDS on patients who presented to the pediatric ED for medical clearance before psychiatric evaluation did not alter medical decision for clearance nor necessitate any change in management or interventions before psychiatric evaluation.

Think ultrasound first for peritonsillar swelling

Peritonsillar abscess (PTA) is one of the most common deep neck space infections that can potentially have life-threatening complications if inadequately diagnosed and not treated promptly. The ability of clinicians to reliably differentiate PTA from peritonsillar cellulitis by physical examination alone is limited and blind needle aspiration, the typical method of diagnosis of PTA, is also unreliable. We review the available evidence supporting the use of ultrasound, either intraoral ultrasound or transcutaneous ultrasound to be the initial imaging modality of choice for evaluation of PTA and be used for real-time needle guidance.

Heart failure secondary to dilated cardiomyopathy: a role for emergency physician bedside ultrasonography.

Abstract Heart failure as a result of cardiomyopathy is an uncommon presentation in the pediatric emergency department (PED). The initial presenting symptoms in these cases are often nonspecific and may be confused with more common pediatric illnesses. We report a case of a 3-year-old girl initially discharged from a PED after routine evaluation of vomiting and diarrhea with a diagnosis of acute gastroenteritis only to return 1 week later in heart failure from a dilated cardiomyopathy. A bedside ultrasound performed by the emergency physician in the PED allowed for the initiation of appropriate, rapid, goal-directed therapy and expedited timely transport to a facility with pediatric cardiothoracic surgery. We will review dilated cardiomyopathy and the role of emergency physician echocardiography.

A Comparison of Cosmetic Outcomes of Lacerations on the Extremities and Trunk Using Absorbable Versus Nonabsorbable Sutures

OBJECTIVES The primary objective was to compare the cosmetic outcomes of traumatic trunk and extremity lacerations repaired using absorbable versus nonabsorbable sutures. The secondary objective was to compare complication rates between the two groups. METHODS This was a randomized controlled trial comparing wounds repaired with Vicryl Rapide and Prolene sutures. Pediatric and adult patients with lacerations were enrolled in the study. At a 10-day follow-up, the wounds were evaluated for infection and dehiscence. After 3 months, patients returned to have the wounds photographed. Two plastic surgeons blinded to the method of closure rated the cosmetic outcome of each wound using a 100-mm visual analog scale (VAS). Using a noninferiority design, a VAS score of 13 mm or greater was considered to be a clinically significant difference. We used a Students t-test to compare differences between mean VAS scores and odds ratios (ORs) to compare differences in complication rates between the two groups. RESULTS Of the 115 patients enrolled, 73 completed the study including 35 in the Vicryl Rapide group and 38 in the Prolene group. The mean (±SD) age of patients who completed the study was 22.1 (±15.5) years, and 39 were male. We found no significant differences in the age, race, sex, length of wound, number of sutures, or layers of repair in the two groups. The observers mean VAS for the Vicryl Rapide group was 54.1 mm (95% confidence interval [CI] = 44.5 to 67.0 mm) and for the Prolene group was 54.5 mm (95% CI = 45.7 to 66.3 mm). The resulting mean difference was 0.5 mm (95% CI = -12.1 to 17.2 mm; p = 0.9); thus noninferiority was established. Statistical testing showed no differences in the rates of complications between the two groups, but a higher percentage of the Vicryl Rapide wounds developed complications. CONCLUSIONS The use of absorbable sutures for the repair of simple lacerations on the trunk and extremities should be considered as an alternative to nonabsorbable suture repair.
