We have identified modifiable risk factors for delirium. Future studies should aim at implementing strategies to modify these risk factors and evaluate their impact on the risk of delirium.
The evidence supporting the use of IO route for the administration of antidotes in a context of poisoning is scarce. The majority of the evidence consists of case reports and animal experiments. Common antidotes such as acetylcysteine, fomepizole, and digoxin-specific antibody fragments have not been studied or reported with the use of the IO route. Despite the low-quality evidence available, IO access is a potential option for antidotal treatments in toxicological resuscitation when IV access is unavailable.
PurposeTo determine the physical compatibility of 10% calcium chloride and 10% calcium gluconate in combination with injectable solutions, administered in the paediatric and adult intensive care unit setting during toxicological resuscitation involving calcium channel blockers and beta-blockers.MethodsForty-eight combinations were prepared at room temperature, including the following products: calcium chloride, calcium gluconate, insulin, epinephrine, norepinephrine, highly concentrated dextrose solution, sodium chloride, Plasma-Lyte A and Ringer’s lactate. A visual evaluation at times 0, 1, 4, 24, 48 and 72 hours and a particle count test with the LS-20 particle counter at times 0, 4, 24 and 72 hours were performed. The admixtures were considered incompatible if there was a precipitate, a colour change, turbidity, viscosity or a gas formation. The stability of calcium salts was also tested in empty IV bags and syringes by the particle count test.ResultsAll drug mixtures were found to be compatible by visual evaluation and using the particle counter based on United States Pharmacopoeia chapter 788 (USP<788>) specifications. Calcium salts were compatible with insulin and vasopressors in the tested combinations. The stability of 10% calcium salts in empty IV bags and polypropylene syringes was demonstrated for up to 48 hours at room temperature.ConclusionAll the combinations tested were physically compatible for up to 72 hours at room temperature. Clinical use of calcium salt infusions, at an undiluted concentration, in combination with these injectable solutions in a toxicological resuscitation context is considered clinically acceptable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
