RESUMEN

OBJECTIVE: The authors set out to investigate perceived and actual availability of antidotes recommended for stocking in emergency departments (EDs) by the College of Emergency Medicine in EDs in the South West of England. METHODS: Data collectors were asked to physically locate each relevant antidote in the ED, and check whether the recommended quantity was available. If the antidote was not available in the department, the data collector located where in the hospital stocks were available. Senior medical and nursing staff were asked to specify where they believed the antidotes were stored or who they would ask if they did not know. It was then ascertained whether their source of advice would have known the location. RESULTS: 5 out of 6 departments returned data with an overall response rate from senior medical and nursing staff of 80%. Knowledge of common antidote locations was variable, and stocking of antidotes did not universally meet the College of Emergency Medicine recommendations. CONCLUSION: Stocking of important antidotes should be rationalised and simplified using central locations, preferably close to the ED. Clinically important antidotes may not be available for patients when they need them. Clear guidance should be available for staff detailing the location of antidotes. There is a need for clarification around the treatment of cyanide poisoning to facilitate rational antidote stocking for this potentially lethal condition.

RESUMEN

Continental-scale expansion of the East Antarctic Ice Sheet during the Eocene-Oligocene Transition (EOT) is one of the largest non-linear events in Earth's climate history. Declining atmospheric carbon dioxide concentrations and orbital variability triggered glacial expansion and strong feedbacks in the climate system. Prominent among these feedbacks was the repartitioning of biogeochemical cycles between the continental shelves and the deep ocean with falling sea level. Here we present multiple proxies from a shallow shelf location that identify a marked regression and an elevated flux of continental-derived organic matter at the earliest stage of the EOT, a time of deep ocean carbonate dissolution and the extinction of oligotrophic phytoplankton groups. We link these observations using an Earth System model, whereby this first regression delivers a pulse of organic carbon to the oceans that could drive the observed patterns of deep ocean dissolution and acts as a transient negative feedback to climate cooling.
