s: Linkou Chang Gung Memorial Hospital, Taiwan has been on the forefront of efforts to manage and mitigate the Coronavirus Disease 2019 (COVID-19) pandemic since 20th January 2020. Despite having one of the largest and busiest emergency departments (EDs) in the world, we have managed to maintain a “zero-infection” rate among our ED healthcare workers through various systematic approaches. The measures implemented include establishing a clear flowchart with route planning, strict infection control policies and regulation of medical equipment, and team-based segregation in the workplace. These strategies, borne of our experience during the severe acute respiratory syndrome (SARS) outbreak, can complement a network of well-trained personnel to enable EDs around the world in successfully mounting an effective defense against new airborne illness while minimizing healthcare personnel casualties.

Stimulant poisoning frequently causes altered mental status (AMS) and can result in severe cerebral vascular complications. The role of noncontrast brain computed tomography (CT) in acute stimulant-poisoned patients presenting with AMS remains unclear.We examined the results and impacts of brain CT in acute stimulant-poisoned patients with AMS.We performed a retrospective single-center study that included all adult patients who presented to the emergency department with stimulant poisoning and AMS (Glasgow coma scale [GCS] score15) between January 1, 2010 and December 31, 2017. Patients who had concomitant head trauma or who presented with focal neurologic symptoms were excluded. The primary outcome was the rate of acute abnormalities on brain CT. The secondary outcomes were to identify factors that affected the decision to perform brain CT in stimulant-poisoned patients with AMS and whether obtaining the brain CT scan itself affected the patients' prognoses.The analysis included 66 patients, of whom 6 died from the poisoning. Noncontrast brain CT was performed in 31 patients and none had acute abnormalities. Patients who underwent brain CT were found to have worse GCS scores, higher body temperatures, higher intubation rates, higher admission rates, longer admission periods and intensive care unit stays, and a higher mortality rate. After adjusting for the propensity score, performing brain CT itself did not independently affect the patients' clinical outcomes.Nontrauma stimulant-poisoned patients presenting with AMS and without focal neurologic symptoms were unlikely to have acute abnormalities on brain CT. Patients who underwent brain CT scans had worse consciousness and greater disease severity.

Background An optimized protocol to help dispatchers identify potential cases of cardiac arrest and provide phone instructions for cardiopulmonary resuscitation (CPR) may increase the provision of bystander CPR, further improving the survival rate and neurological outcomes. Objective We assessed a revised dispatcher-assisted (DA)-CPR protocol with a continuous quality-improvement feature in a county fire department-based emergency medical services system. Methods This was a before-and-after intervention prospective study conducted in Taoyuan City, Taiwan. The participants were out-of-hospital cardiac arrest (OHCA) patients from November 2014 to February 2016. Interventional quality control started in August 2015. Approximately 10% of the telephone calls from these OHCA patients were reviewed. Results In total, 66 and 64 cases were included in the before- and after-intervention groups, respectively. No significant differences were observed in sex, age, day, and time of events, or languages spoken by the callers. After the intervention, we found significant improvements in the rates at which cardiac arrests were recognized (54.5% vs. 68.8%; p = 0.007) and normal breathing was checked (51.5% vs. 76.6%, p = 0.003). Moreover, the frequency with which DA-CPR was provided by the dispatchers improved significantly (50.0% vs. 72.7%; p = 0.046). Significant improvement in patient outcomes was observed with regard to 24-h survival (7.6% vs. 20.3%, p = 0.036) but not with regard to survival to discharge (3.0% vs. 10.9%, p = 0.076). Conclusions The study found this DA-CPR protocol, which includes continuous quality control, is promising as it improved the successful recognition of cardiac arrests.

Background Meprobamate tablets contain microcrystalline cellulose, a potent embolic agent that has been shown to cause gangrene in animal studies. Microvascular embolization caused by microcrystalline cellulose can contribute to the ischemic process. Objective We report a case of acute hand ischemia after accidental intra-arterial injection of crushed meprobamate powder in a 23-year-old male drug abuser. Case Report The distal tips of the patient’s right thumb, index finger, ring finger, and little finger continued to develop gangrene despite medical therapy with heparinization, low molecular-weight dextran infusion, corticosteroid administration, and hyperbaric oxygen therapy. Conclusion We believe this is the first case of acute limb ischemia caused by intra-arterial injection of meprobamate powder documented in humans. Emergency physicians should be aware that accidental intra-arterial injection of crushed oral drug formulations is potentially limb threatening and prompt recognition of similar clinical scenarios is of vital importance.

Rapid sequence intubation (RSI) has achieved high success and low complication rate in the ED. However, hypotension after RSI does occur. This study aimed to identify the prognostic factors of hypotension after RSI.This study identified patients who needed emergency airway management and then divided them into 2 groups. Patients in the first group were the hypotension group, whose systolic blood pressure (SBP) was found to be greater than 90 mm Hg before RSI but less than 90 mm Hg after RSI. Patients in the second group were deemed as the control group whose pre-SBP and post-SBP were greater than 90 mm Hg. The following variables were measured in the study: age, sex, body weight, patients' underlying disease and ongoing disease, the initial vital signs, and laboratory tests. A prognostic model with multiple logistic regression was established based on significant findings from univariate analysis.A total of 149 patients were recruited from the ED in this study, with 28 patients in the hypotension group and 121 patients in the control group. After univariate analysis, there were 6 factors identified as significant findings including chronic obstructive pulmonary disease, sepsis, albumin, lidocaine, low body weight (55 kg), and preintubation blood pressure of less than 140 mm Hg. Multiple logistic regression has demonstrated that patients' underlying diseases, anthropometric parameters, and drug medications were factors related to postintubation hypotension among ED patients.Clinical practitioners in the ED should take a patient's predisposing factors into serious consideration before emergency intubation while a preplanned strategy is made.
