BACKGROUND:Emergency physicians (EPs) often care for patients with acute small bowel obstruction. While some patients require exploratory laparotomy, others are managed successfully with supportive care. We aimed to determine features that predict the need for operative management in emergency department (ED) patients with small bowel obstruction (SBO). METHODS:We performed a retrospective chart review of 370 consecutive patients admitted to a large urban academic teaching hospital with a diagnosis of SBO over a two-year period. We evaluated demographic characters (prior SBO, prior abdominal surgery, active malignancy) and clinical findings (leukocytosis and lactic acid) to determine features associated with the need for urgent operative intervention. RESULTS:Patients with a prior SBO were less likely to undergo operative intervention [20.3% (42/207)] compared to those without a prior SBO [35.2% (57/162)]. Abnormal bloodwork was not associated with need for operative intervention. 68% of patients with CT scan findings of both an SBO and a hernia, however, were operatively managed. CONCLUSIONS:Patients with a history of SBO were less likely to require operative intervention at any point during their hospitalization. Abnormal bloodwork was not associated with operative intervention. The CT finding of a hernia, however, predicted the need for operative intervention, while other findings (ascites, duodenal thickening) did not. Further research would be helpful to construct a prediction rule, which could help community EPs determine which patients may benefit from expedited transfer for operative management, and which patients could be safely managed conservatively as an initial treatment strategy.

BACKGROUND: Emergency physicians frequently encounter patients with acute small bowel obstructions (SBO). Although computed tomography (CT) imaging is the current gold standard in the assessment of patients with suspected SBO in the emergency department, a few studies have examined the use of ultrasound as an alternative imaging technique. METHODS: We evaluated the accuracy of ultrasound performed in the ED by a variety of providers (physicians with various levels of training, physician assistants) compared to CT imaging in 47 patients with suspected SBOs. RESULTS: Our data demonstrated a sensitivity of 93.8% and a specificity of 93.3% when compared to abdominal CT, and a sensitivity of 94.3% and specificity of 95.2% using a composite endpoint of abdominal CT and discharge diagnosis. CONCLUSION: Ultrasound can play an important role in the identification of small bowel obstructions in ED patients.

We present a case of an elderly gentleman who was punched in the face and subsequently diagnosed by an emergency physician with acute angle closure glaucoma secondary to a posterior lens dislocation. Slit lamp evaluation, ocular ultrasound, and computed tomography (CT) imaging, can identify a dislocated lens. A rare complication of a lens dislocation includes secondary acute angle closure glaucoma. Treatment of lens dislocation includes prosthetic lens placement or reattachment in cases of a partial lens dislocation.

BACKGROUND:
Volume resuscitation has only been demonstrated to be effective in approximately fifty percent of patients. The remaining patients do not respond to volume resuscitation and may even develop adverse outcomes (such as acute pulmonary edema necessitating endotracheal intubation). We believe that point-of-care ultrasound is an excellent modality by which to adequately predict which patients may benefit from volume resuscitation.
DATA RESOURCES:
We performed a search using PubMed, Scopus, and MEDLINE. The following search terms were used: fluid responsiveness, ultrasound, non-invasive, hemodynamic, fluid challenge, and passive leg raise. Preference was given to clinical trials and review articles that were most relevant to the topic of assessing a patient’s cardiovascular ability to respond to intravenous fluid administration using ultrasound.
RESULTS:
Point-of-care ultrasound can be easily employed to measure the diameter and collapsibility of various large vessels including the inferior vena cava, common carotid artery, subclavian vein, internal jugular vein, and femoral vein. Such parameters are closely related to dynamic measures of fluid responsiveness and can be used by providers to help guide fluid resuscitation in critically ill patients.
CONCLUSION
Ultrasound in combination with passive leg raise is a non-invasive, cost- and time-effective modality that can be employed to assess volume status and response to fluid resuscitation. Traditionally sonographic studies have focused on the evaluation of large veins such as the inferior vena cava, and internal jugular vein. A number of recently published studies also demonstrate the usefulness of evaluating large arteries to predict volume status.
