A preliminary evaluation of emergency ultrasound in the setting of an emergency medicine training program.

In this article we seek to evaluate the diagnostic accuracy of emergency physicians performing emergency ultrasonography in the setting of an emergency medicine training program. A prospective observational study was performed at an inner city Level I trauma center with an emergency medicine residency training program. From July 1994 to December 1996 a convenience sample of ultrasound exams was recorded. The diagnostic quality ("acceptable or technically limited") was determined by a board-certified cardiologist or radiologist with fellowship training in ultrasonography. The emergency department interpretations were then compared to those of the blinded cardiologist or radiologist. Four hundred and fifty-six ultrasound examinations were videotaped and entered into the study; 408 (89%) of the studies performed were determined to be "acceptable." The diagnostic accuracy (sensitivity, specificity, positive and negative predictive values) of these studies were as follows: cardiac, to rule out effusion (n = 67; 0.83, 0.98, 0.88, 0.98); transabdominal, to rule out abdominal aortic aneurysms (AAA), cholelithiasis, or free peritoneal fluid (n = 263; 0.91, 0.89, 0.88, 0.92); renal, to rule out hydronephrosis (n = 45; 0.94, 0.96, 0.94, 0.96); pelvic, to rule in intrauterine pregnancy (n = 33; 1.0, 0.90, 0.96, 1.0). The 48 "technically limited studies" included: 39 transabdominal (33 gallbladder, 1 abdominal aortic aneurysm, 5 free peritoneal fluid), 6 cardiac, 2 renal, and 1 pelvic ultrasound. This study suggests that emergency physicians with a minimal amount of training display acceptable technical skill and interpretive acumen in their approach to emergency ultrasonography.

C-spine injury associated with gunshot wounds to the head: retrospective study and literature review.

OBJECTIVE: To determine the incidence of C-spine injury (CSI) associated with gunshot wounds (GSWs) to the head. METHODS: A retrospective chart review including patients with GSWs to the head and excluding those with penetrating facial/neck trauma was performed. Cervical clearance was by clinical/radiologic criteria in survivors, and autopsy in nonsurvivors. A MEDLINE literature search was performed and relevant articles reviewed. RESULTS: One hundred seventy-four charts were available for review; 90 had C-spine radiographs (complete series [49], lateral [33], and computed tomographic scan [8]). Of 84 with no radiographs, 29 were clinically cleared, and 55 died (32 cleared at autopsy). Twenty-three died without evaluation. None of the remaining 151 (87%) had CSI. Literature search yielded only three relevant articles. Combining the data from these articles yielded 534 patients, and CSI was excluded in 507 (95%). CONCLUSION: C-spine immobilization and diagnostic radiography are probably not necessary in patients with isolated GSWs to the head and may complicate and delay emergency airway management.

Evaluation of an instructional model for emergency ultrasonography.

OBJECTIVE: To evaluate a 4-hour ultrasonography course in the setting of an emergency medicine (EM) training program. METHODS: EM residents and faculty at a large urban center were provided a 4-hour emergency ultrasonography course. Then, during an 18-month period, a nonconsecutive sample of ultrasonographic examinations were videotaped and later reviewed. The interpretations of the emergency, physician examinations were compared with the following reference standards: 1) an official ultrasound performed and interpreted by the departments of radiology or cardiology; 2) an operative report; 3) A CT scan or i.v. pyelogram (IVP); or 4) a cardiologist's or a radiologist's interpretation of the videotaped examinations. RESULTS: Of 258 examinations reviewed, 28 (11%) of these were excluded because the cardiologist or radiologist reviewing the videotape determined them to be "technically limited" studies. Of the remaining 230 examinations, there were: 127 gallbladder studies [disease prevalence = 0.58; sensitivity = 0.89; specificity = 0.80; kappa (kappa) = 0.69; 95% CI: 56-82%]; 39 echocardiograms to rule out pericardial effusions [disease prevalence = 0.15; sensitivity = 0.83; specificity = 0.97 kappa = 0.80; 95% CI: 54-100%]; 25 abdominal ultrasounds to rule out free peritoneal fluid [disease prevalence = 0.32; sensitivity = 0.88; specificity = 0.94; kappa = 0.81; 95% CI: 26-95%]; 16 renal ultrasounds to rule out hydronephrosis [disease prevalence = 0.25; sensitivity = 1.0; specificity = 0.92; kappa = 0.84; 95% CI: 56-100%]; 12 pelvic ultrasounds to rule in an intrauterine pregnancy [disease prevalence = 0.67; sensitivity = 1.0; specificity = 0.75; kappa = 0.80; 95% CI: 43-100%]; and 11 abdominal ultrasounds to rule out abdominal aortic aneurysms [disease prevalence = 0.09; sensitivity = 1.0; 95% CI: 2.5-91%; specificity = 1.0; 95% CI: 68-100%]. CONCLUSIONS: This 4-hour ultrasonography course has potential to serve as a foundation for an instructional model for ultrasonography training in the setting of an EM residency program.

Credentialing issues in emergency ultrasonography.

The use of ultrasonography, traditionally performed by radiologists, is becoming increasingly widespread in emergency medicine. Consequently, much debate has evolved over whether emergency medicine physicians are qualified to provide this service, and the criteria by which training and credentialing can be achieved. This article discusses training and credentialing guidelines, paths to becoming credentialed in emergency sonography, and quality assurance issues. Also, strategies are proposed for emergency departments seeking to perform emergency sonography.

Perimortem cesarean section: case reports and recommendations.

Perimortem cesarean section is rarely required in the ED. However, since trauma now represents a leading cause of nonobstetric maternal death, emergency physicians (EPs) may more commonly be faced with the difficult decision of performing an emergency cesarean section. Two cases are described of severely traumatized pregnant patients for whom perimortem cesarean section in the ED led to birth of viable infants, with one long-term survivor. The rationale and guidelines for the procedure are discussed, and it is emphasized that the EP should be thoroughly familiar with the procedure and prepared to perform it when indicated to enhance fetal (and potentially maternal) survival.

The facilitated pediatric resuscitation room.

Pediatric resuscitation is challenging for the emergency physician because the diverse range in the age and size of the patients encountered complicates the appropriate selection of medications, equipment, and supplies. The following enhancements in the pediatric resuscitation room were made to facilitate effective management of critically ill neonates and children: 1) expanding the concept of the Broselow tape as the central color theme of organization of all medication doses and equipment; 2) use of a large, simplified, color-coded wall chart to define patient parameters; 3) color-coded equipment; 4) adjustable "break-away" resuscitation stretcher; and 5) equipment suspended from the ceiling: a) radiant warmer; b) suction, oxygen, and electricity; c) cardiac monitor and fluid controller; d) X-ray unit. These changes give the resuscitation team greater accessibility to both the patient and the needed resuscitation supplies.
