Calabadions are heterocyclics molecule that offers rapid and complete reversal of both aminosteroids, such as rocuronium and vecuronium, and benzylisoquinoline NMBDS, such as atracurium and cisatracurium.
Notably, calabadion 2 binds rocuronium 89 times stronger than sugammadex. Additionally it also binds etomidate and ketamine.
Calabadions are still undergoing pre-human animal testing, and so are some time away from entering clinical practice.summary
A growing collection of landmark papers relevant to intensive care and critical care medicine.
These papers are practice changing and hold current, ongoing significance beyond their historical importance.
This is a dynamic and changing document that will be updated, pruned and added to as appropriate. Many of these papers have free full-text provided by the publisher because of their significance.summary
The potential for dexamethasone and other glucocorticoids to prolong peripheral nerve blocks was first noted almost 20 years ago.
While the effect has been observed with several different blocks (upper & lower extremity, and even TAP blocks), the clinical significance varies and several questions still remain:
Is the effect exclusive to perineural dexamethasone? Several studies have observed similar effects for both IV and perineural dexamethasone (though less profound than other papers).
Is the effect safe? This is perhaps the most concerning, as there are suggestions that the effect may represent an enhancement of the well-known neurotoxicity of local anaesthetic agents.
