Lactate, bicarbonate and anion gap for evaluation of patients presenting with sepsis to the emergency department: A prospective cohort study.
A serum lactate level >2 mmol/L has been chosen as the preferred cut-off value for screening of patients with suspected sepsis. In patients with suspected sepsis presenting to the ED, we aimed to determine the outcomes of patients with initial lactate levels ≤2 mmoL/L, but abnormal bicarbonate or anion gaps (AGs). ⋯ A normal lactate level alone should not be used to exclude life-threatening sepsis. Patients with metabolic acidosis characterised by low bicarbonate or high AG levels, but with normal lactate levels, have high rates of ICU requirement and mortality and should also be considered for early, aggressive therapy.

Observational StudyUtility of calcium, magnesium and phosphate testing in the emergency department.
To determine how frequently calcium (Ca), magnesium (Mg) and phosphate (PO4 ) tests change ED patient management. ⋯ Ca, Mg and PO4 testing is common. However, the yield of clinically significant abnormal levels is low and patient management is rarely changed. Testing of these electrolytes needs to be rationalised.

Emergency first aid readiness in Antarctica: Australian Antarctic expeditioners' first aid credentials and self-efficacy.
To help prevent future morbidity and mortality, this study examined Australian Antarctic expeditioners' first aid credentials and self-efficacy in providing emergency first aid in extreme environments. ⋯ These findings revealed that many Antarctic expeditioners may not be adequately prepared for first aid emergencies and have low confidence in handling complex medical situations. Based on these findings, we recommend higher first aid qualifications and training tailored to the Antarctic context. These modest steps can help prevent unnecessary and costly morbidity and mortality for extreme-condition expeditioners.
