Why are we so bad at NMB reversal?

• Insufficient monitoring• Wide interindividual variation in pharmacokinetics• Low sensitivity of detecting residual block• Time to recovery to TOF ratio >0.9

So what?

• 6/14 with residual block aspirated (TOF ratio <0.9)

Sugammadex to treat anaphylaxis to rocuronium• NMBs are the most common causal agents in

anesthesia (55-69%)• Allergen is the quarternary ammonium ion• Sugammadex encapsulates free allergen• Slows/halts immunologic process

Treatment for Roc anaphylaxis - not so simple• Some of the epitope might protrude from complex• Incorrect causative agent in 1/3 of cases• Sugammadex vs IgE – which has great affinity for

rocuronium

Anaphylaxis to sugammadex• Japanese study: Hypersensitivity 0.22%; Anaphylaxis 0.039%

(n=15479)– Same rate as rocuronium or succinylcholine

• Skin prick testing• No commercially available IgE assays• Average person consumes 4g of gamma-cyclodextrin daily• Oral sensitization resulting in anaphylaxis to “first” exposure• Symptoms might develop after extubation

Renal failure

• Sugammadex is entirely renally excreted• Hepatic elimination of rocuronium eliminated once

bound to sugammadex • Plasma clearance complex = GFR (120 ml/min).• High-flux dialysis effective in removing
