Intramuscular adrenaline to improve outcomes following cardiac arrest – An experimental porcine study Open
Early intramuscular injection of adrenaline 5 min prior to intravenous adrenaline did not increase the ROSC rate but resulted in a prolonged absorption with higher adrenaline levels at 30 and 60 min after ROSC.

Regional pulmonary function testing: a new tool for screening subjects with preserved ratio impaired spirometry? Open
It is feasible to use electrical impedance tomography-based regional lung function information to detect impairments in the respiratory system, which matched the symptoms and quality of life assessment better than traditional spirometry. h…
