New Versus Old, The i-View Video Laryngoscope Versus the GlideScope: A Prospective, Randomized, Crossover Trial.

BACKGROUND: A novel video laryngoscope device, the i-view, may extend intubation capability to the lowest echelons of deployed military medicine. The i-view is a one-time use, disposable laryngoscope. We compared time to completion of endotracheal intubation (ETI) between the i-view and GlideScope among military emergency medicine providers in a simulation setting. METHODS: We conducted a prospective, randomized, crossover trial. We randomized participants to i-view or GlideScope first before they performed 2 ETI-1 with each device. The primary outcome was time to completion of ETI. Secondary outcomes included first-pass success, optimal glottic view, and end-user appraisal. We used a Laerdal Airway Management Trainer for all intubations. RESULTS: Thirty-three emergency medicine providers participated. ETI time was less with GlideScope than i-view (22.2 +/- 9.0 seconds versus 30.2 +/- 24.0 seconds; p=0.048). Optimal glottic views, using the Cormack-Lehan scale, also favored the GlideScope (2 [1,2] versus 2[2,2]; p=0.044). There was no difference in first-pass success rates (100% versus 100%). More participants preferred the GlideScope (24 versus 9; p=0.165); however, participants agreed that the i-view would be easier to use than the GlideScope in an austere environment (4[4,5]). CONCLUSIONS: We found the GlideScope outperformed the i-view with respect to procedural completion time. Participants preferred the GlideScope over i-view, but indicated the i-view would be easier to use than the GlideScope in an austere setting. Our findings suggest the i-view may be a suitable alternative to GlideScope for US military providers, especially for those in the prehospital setting.

Unusual Case of Acute Decompensated Maple Syrup Urine Disease in the Emergency Department.

A case report of an army soldier presenting to the emergency department with acute metabolic derangement resulting in encephalopathy, cerebral edema, and death is presented. The patient had no medical diagnoses before entering military service and was triaged in the emergency department with the common complaint of presyncope. However, as encephalopathy worsened, the patient experienced altered mental status, lethargy, emesis, and seizure. This patient ultimately died because of rapid decompensation. Maple syrup urine disease pathophysiology and treatment recommendations are reviewed.

Utility of Nonspecific Laboratory Testing for Psychiatric Patients Undergoing Medical Screening in a Military Emergency Department.

INTRODUCTION: Psychiatric complaints account for a sizable and increasing portion of emergency department (ED) visits. Compared with other medical patients, these patients often require substantial resources because of limited specialized resources and prolonged boarding times, which can be detrimental to the safety and satisfaction of other patients. This can prompt early and indiscriminate laboratory testing to expedite early requests for admission consideration. Numerous emergency medicine literature and clinical policies already recommend against indiscriminate screening labs for these patients, yet many psychiatric services require these tests. This study further evidences the limited clinical utility and high associated costs of mandatory protocol screening labs for psychiatric patients evaluated in military EDs. MATERIALS AND METHODS: A retrospective chart review of 441 active duty military patients and their families presenting to Madigan Army Medical Center's ED who received psychiatric diagnoses underwent analysis. A 3-physician review panel evaluated each identified patient case to confirm eligibility and determine whether or not laboratory studies led to a change in patient disposition that was not identified by history, review of systems, physical exam, and known past medical history. The review was approved by the hospital's institutional review board. Contemporary laboratory tests ordered in the evaluation of these patients included complete blood count with differential, complete metabolic panel, thyroid-stimulating hormone, serum ethanol, serum acetaminophen, serum salicylates, urine drug screening, urinalysis, urine human chorionic gonadotropin, and electrocardiograms. RESULTS: Broad screening labs may have altered dispositions for 0.9% (4) of patients. In total, 93% (202) of admitted patients were dispositioned to a psychiatric service. Of the 15 patients admitted to a medical service, 10 involved overdoses or intoxication. One patient had anemia in addition to opioid use disorder as diagnoses and was dispositioned to a medicine service. One pediatric patient was admitted for observation only. The remaining patients had diagnoses based on physical exam and history requiring medical service admission. In total, 7 patients had unknown dispositions, of which 4 carried solely psychiatric diagnoses. CONCLUSIONS: The cumulative reimbursement costs of broad testing in the studied population were estimated at $36,325.17 and rarely altered patient disposition. Further testing does not increase the incidence of disposition altering diagnoses and is associated with increased costs. When individual state laws and the clinical assessment by the responsible emergency physician are considered, future standardized ED lab screening evaluations of psychiatric patients in military EDs may be concentrated to breathalyzer alcohol level, urine drug screen, serum salicylates, serum acetaminophen, and urine human chorionic gonadotropin.
