Randomized Controlled Trial Comparative Study
Performance accuracy of hand-on-needle versus hand-on-syringe technique for ultrasound-guided regional anesthesia simulation for emergency medicine residents.
Ultrasound-guided nerve blocks (UGNB) are increasingly used in emergency care. The hand-on-syringe (HS) needle technique is ideally suited to the emergency department setting because it allows a single operator to perform the block without assistance. The HS technique is assumed to provide less exact needle control than the alternative two-operator hand-on-needle (HN) technique; however this assumption has never been directly tested. The primary objective of this study was to compare accuracy of needle targeting under ultrasound guidance by emergency medicine (EM) residents using HN and HS techniques on a standardized gelatinous simulation model. ⋯ For EM residents learning UGNBs, the HN technique was not associated with superior needle control. Our results suggest that the single-operator HS technique provides equivalent needle control when compared to the two-operator HN technique.

Comparative Study
Compassion fatigue is similar in emergency medicine residents compared to other medical and surgical specialties.
Compassion fatigue (CF) is the emotional and physical burden felt by those helping others in distress, leading to a reduced capacity and interest in being empathetic towards future suffering. Emergency care providers are at an increased risk of CF secondary to their first responder roles and exposure to traumatic events. We aimed to investigate the current state of compassion fatigue among emergency medicine (EM) resident physicians, including an assessment of contributing factors. ⋯ CF scores in EM residents are similar to residents in other surgical and medical specialties. Residents working primarily night shifts and those working more than 80 hours per week appear to be at high risk of developing compassion fatigue. Residents with children are more likely to experience secondary traumatic stress.

There is scant literature regarding the optimal resident physician staffing model of academic emergency departments (ED) that maximizes learning opportunities. A department of emergency medicine at a large inner-city academic hospital initiated a team-based staffing model. Its pre-interventional staffing model consisted of residents and attending physicians being separately assigned patients, resulting in residents working with two different faculty providers in the same shift. This study aimed to determine if the post-interventional team-based system, in which residents were paired with a single attending on each shift, would result in improved residents' learning and clinical experiences as manifested by resident evaluations and the number of patients seen. ⋯ Adopting a team-based physician staffing model is associated with improved resident perceptions of quality and amount of teaching. Residents also experience a greater number of patient evaluations in a team-based model.

Case Reports
Mirror image artifact mimicking heterotopic pregnancy on transvaginal ultrasound: case series.
Vaginal bleeding in early pregnancy is a common emergency department complaint. Point-of-care ultrasound is a useful tool to evaluate for intrauterine ectopic pregnancy. Emergency physicians performing these studies need to be cognizant of artifacts produced by ultrasound technology, as they can lead to misdiagnosis. We present two cases where mirror-image artifacts initially led to a concern for heterotopic pregnancies but were excluded on further imaging.
