<p>
“Push dose pressors” – administration of small doses of vasopressors in the emergency room has become a common practice. A recently published study investigated the incidence of human error and adverse hemodynamic events.</p>
<p>
Push dose pressors were defined as:</p>
<ul>
<li>
Phenylephrine (any dose)</li>
<li>
Epinephrine (<= 100 mcg) </li>
</ul>
<p>
Adverse hemodynamic event was defined as:</p>
<ul>
<li>
Extreme tachycardia (HR > 140 bmp)</li>
<li>
New bradycardia (HR < 60 bmp)</li>
<li>
Hypertension (SBP > 180 mmHg)</li>
<li>
Ventricular tachycardia</li>
</ul>
<p>
249 out of 1522 patients were identified and analyzed from Jan 2010 to November 2017</p>
<ul>
<li>
median initial epinephrine dose (20 mcg; IQR: 10-100; range 1-100)
<ul>
<li>
recieved more than one dose: 78 (57%)</li>
</ul>
</li>
<li>
median initial phenylephrine dose (100 mcg; IQR: 100-100; range 25 to 10,000)
<ul>
<li>
received more than one dose: 62 (56%)</li>
</ul>
</li>
</ul>
<p>
Adverse event</p>
<ul>
<li>
Phenylephrine group (n=110): 30 (27%; 95% CI: 19-36%)</li>
<li>
Epinephrine group (n=139): 68 (50%; 95% CI: 41-58%)</li>
</ul>
<p>
Errors</p>
<ul>
<li>
Human error: 47 (19%) - similar proportion of human error between two agents.</li>
<li>
Dosing error: 7 (3%; 2.5 to 100-fold)</li>
<li>
Documentation error: 43 (17%)</li>
<li>
Only one dosing error occurred when a pharmacist was present</li>
</ul>
<p>
</p>
<p>
<strong>Conclusion</strong></p>
<ul>
<li>
Human errors and adverse hemodynamic event were common when “push dose pressors” were administered.</li>
<li>
Consultation with a pharmacist can/may reduce dosing error.</li>
</ul>
