Objective
Eye deviation is recognized as a clinical indicator of brain function in acute brain injury. This study investigated the association between radiological eye deviation on brain computed tomography (CT) and neurological outcomes in post–cardiac arrest patients.
Methods
This single-center retrospective observational study included adult patients with out-of-hospital cardiac arrest of presumed medical cause who achieved return of spontaneous circulation and underwent brain CT within 24 hours between January 2012 and December 2022. Radiological lateral eye deviation angles were quantitatively measured on brain CT images. Multivariate logistic regression analysis was performed to identify independent predictors of poor neurological outcome at hospital discharge and in-hospital mortality. Receiver operating characteristic curve analysis was used to assess the diagnostic performance of eye deviation angles and serum biomarkers.
Results
Among 141 patients, 127 had poor neurological outcomes. Nonconjugate eye deviation was more frequent in the poor outcome group (71.7% vs. 42.9%) and showed a significant association in univariate analysis (odds ratio, 3.37; 95% confidence interval, 1.10–10.90; P=0.035), but it lost significance after multivariate adjustment. The diagnostic accuracy of the conjugate eye deviation angle was modest (area under the curve [AUC], 0.611) and inferior to that of serum S-100B protein (AUC, 0.790).
Conclusion
Radiographic eye deviation on brain CT alone is insufficient to reliably predict neurological outcomes after cardiac arrest. Further large-scale studies incorporating multimodal approaches are warranted to clarify its prognostic value.

Objective
Workplace-based assessment (WBA) plays a crucial role in assessing entrustable professional activities (EPAs) in the competency-based medical education era. This pilot study explored the perceptions of residents and assessors of two WBAs for three Korean Society of Emergency Medicine EPAs.
Methods
Eight emergency medicine (EM) residents underwent WBAs, with mini-clinical evaluation exercises (mini-CEX) conducted by nine EM faculty members and multisource feedback (MSF) provided by two internal medicine faculty members and four emergency room nurses, for a total of 69 assessments. We conducted an anonymous online survey to gather feedback on experiences, perceptions, and recommendations for improving WBA, such as mini-CEX and MSF, with responses scored on a 5-point Likert scale.
Results
Of the 23 initial participants, 15 (65.2%) responded, including 5 residents and 10 assessors. EM faculty viewed mini-CEX favorably, noting its strong integration of supervision and effectiveness in assessing resident performance. EM residents reported comfort issues during assessments, preferring immediate feedback and multiple assessors. MSF was generally perceived positively but showed discrepancies in the utilities of rating scales and feedback types, indicating potential areas for improvement.
Conclusion
Two WBAs for three Korean Society of Emergency Medicine EPAs were found to be feasible and acceptable in the context of Korean EM residency training. However, perceptions varied between assessors and residents, necessitating clear communication about WBA objectives and processes. Our findings are useful for shaping future EPA-based training programs, balancing traditional and WBA methods, and enhancing feedback quality.

The typical presentation of intussusception includes intermittent severe abdominal pain, vomiting, rectal bleeding, and the presence of an abdominal mass. We present a case of intussusception after abdominal blunt trauma along with a literature review. A 4-year-old girl was admitted to the emergency department after a bicycle accident. She complained of progressively worsening abdominal pain, but there was no vomiting, fever, bloody stool, or abdominal mass. She was finally diagnosed with traumatic intussusception by ultrasonography and treated with air reduction. Because the typical symptoms are unusual in traumatic intussusception, close attention must be paid to avoid a delayed diagnosis.

Objective

International Liaison Committee on Resuscitation guidelines advocate an arterial saturation of 94% to 96% after return of spontaneous circulation (ROSC). However, a few clinical trials have investigated the impact of postresuscitative O2 therapy after cardiac arrest. We studied whether early hyperoxemia is associated with a poor post-ROSC outcome after in-hospital cardiac arrest.

 Methods

We retrospectively reviewed patients who experienced an in-hospital cardiac arrest from January 2005 to January 2011. Based on the results of the first arterial blood gas analysis (ABGA) within 10 minutes and a second ABGA from 60 to 120 minutes after ROSC, patients were classified into three groups: hyperoxemia (PaO2 ≥ 300 mmHg), normoxemia (300 mmHg > PaO2 ≥ 60 mmHg), and hypoxemia (PaO2 < 60 mmHg or ratio of PaO2 to fraction of inspired oxygen < 300). We examined whether early hyperoxemia was associated with survival and neurological outcome.

 Results

There were 792 patients who met the inclusion criteria: 638 (80.6%) in the hypoxemia group, 62 (7.8%) in the normoxemia group, and 92 (11.6%) in the hyperoxemia group. Multiple logistic regression analysis showed that hyperoxemia was not associated with survival (odds ratio [OR], 1.07; 95% confidence interval [CI], 0.30 to 3.84) or neurological outcome (OR, 1.03; 95% CI, 0.31 to 3.40).

 Conclusion

Postresuscitation hyperoxemia was not associated with survival or neurological outcome in patients with ROSC after in-hospital cardiac arrest.
