Title: Sugammadex for Reversal of Non-Depolarizing Neuromuscular Blockers<br/>Author: Bryan Hayes<br/><a href='http://umem.org/profiles/faculty/369/'>[Click to email author]</a><hr/><p>
After three failed attempts, the FDA finally granted approval for Merck's non-depolarizing neuromuscular blocker reversal agent sugammadex (Bridion). Though the product has been used in Europe and Asia for several years, hypersensitivity concerns led to the delayed approval in the U.S.</p>
<p>
<strong>Important points</strong></p>
<ol>
<li>
Reverses rocuronium, vecuronium, and to a lesser degree, pancuronium</li>
<li>
Full reversal obtained about 3 minutes after administration</li>
<li>
Eliminated entirely by the kidneys in about 8 hours (6 times longer in patients with CrCl < 30 mL/min)</li>
<li>
Dosing is generally 2-4 mg/kg. Total body weight should be used in obese patients</li>
</ol>
<p>
<strong>Application to Clinical Practice</strong></p>
<ol>
<li>
Potential for use in situations where a neuro exam is needed shortly after intubation (eg, status epilepticus, ICH)</li>
<li>
The risk of serious hypersensitivity appears to be < 1% in published literature</li>
<li>
Cost will most assuredly be high</li>
<li>
Long duration in patients with reduced kidney function means further attempts to re-paralyze with roc, vec, or pancuronium may be unsuccessful </li>
</ol>
