OBJECTIVE: This study was conducted to compare the outcome of cardiopulmonary resuscitation (CPR) with AutoPulse and LUCAS in out-of-hospital cardiac arrest patients. METHODS: Between July 2017 and March 2018, a total of 152 out-of-hospital cardiac arrest patients were included for analysis. Included patients were divided into an AutoPulse group and LUCAS group. Patient's age, sex, bystander CPR, witness arrest, initial shockable rhythm, time from arrest to CPR, pre-hospital CPR duration, in-hospital CPR duration, automatic external defibrillator operation by paramedic, intubation by paramedic, intravenous line access by paramedic and target temperature management were reviewed retrospectively. In addition, blood pH, lactate level, white blood cell (WBC) count, and delta neutrophil index (DNI) were analyzed. Additionally, return of spontaneous circulation (ROSC), hospital and intensive care unit (ICU) length of stay, complications from chest compressions, and cerebral performance category (CPC) scale at discharge were analyzed. RESULTS: No differences in initial shockable rhythm, patient characteristics, management for patients and CPR duration were observed between the two groups. ROSC were significantly higher in the LUCAS group than the AutoPulse group (17.9 vs. 34.7%, P=0.025). However, hospital and ICU length of stay, CPC scale at discharge as clinical outcome and pH, lactate level, WBC count, and DNI as laboratory outcomes were not significantly different between the AutoPulse group and LUCAS group. Although the case numbers were scarce, complications from chest compressions were not significantly different between the two groups. CONCLUSION: CPR using LUCAS showed better ROSC than CPR using AutoPulse. However, hospital and ICU length of stay and CPC scale at discharge did not differ between the two groups.

In this study, we report the case of a 59-year-old male patient with organophosphate pesticide poisoning. He visited the local emergency medical center after ingesting 250 ml of organophosphate pesticide. The patient’s symptoms improved after the initial intravenous infusion of pralidoxime 5 g and atropine 0.5 mg. However, 18 hours after admission, there was a worsening of the symptoms. A high dose of atropine was administered to improve muscarinic symptoms. A total dose of 5091.4 mg of atropine was used for 30 days, and fever and paralytic ileus appeared as side effects of atropine. Anticholinergic symptoms disappeared only after reducing the atropine dose, and the patient was discharged on the 35th day without any neurologic complications.

Objective:
This study examined whether the changes in reimbursement coverage of brain magnetic resonance image (MRI) affected practice for patients who visited the emergency department with dizziness as the chief complaint.
Methods:
Among the 5,423 patients who visited the emergency department for dizziness in 2017, 2019, and 2021, 4,497 patients were included in the study retrospectively and investigated by brain diffusion-weighted MRI and the presence of cerebral infarction on brain diffusion-weighted MRI. This study examined whether there was a significant difference before and after the change.
Results:
In 2017, 2019, and 2021, 1,489, 1,570, and 1,438 patients with dizziness visited the emergency department, respectively. The number of patients who underwent a brain MRI scan gradually increased from 237 (15.9%) in 2017 to 628 (40.0%) in 2019 and 948 (65.9%) in 2021 (P<0.001). The number of positive findings on brain MRI scan increased gradually from 30 patients (2.0%) in 2017 to 47 patients (3.0%) in 2019 and 53 patients (3.7%) in 2021 (P=0.025). The ratio of positive findings of brain MRI scans to the number of patients who underwent brain MRI scans decreased gradually to 12.7% in 2017, 7.5% in 2019, and 5.6% in 2021 (P=0.001).
Conclusion
The changes in the reimbursement coverage of brain MRI affect the number of brain MRI scans and the detection of cerebral infarction.
