Background: In REBEL Cast Episode 73, Anand Swaminathan and I discussed two recent studies on the safety of peripheral vasopressors from two large trials [1][2]. An email from good friend Rory Spiegel brought my attention to yet another trial on this topic [3]. I think we can all agree that in patients with septic shock, or shock in general, the administration of vasopressor agents early, can help to stabilize patients and reverse end-organ hypoperfusion.  Traditionally, this has been done through central venous catheters (CVCs) due to the hypothetical risk of extravasation injury to extremities.  The flip side of this is, that central venous catheters are not without their own risks and time to place them can delay a therapy that may benefit patients.

Background: Traditionally, vasopressors have been given through central venous catheters (CVCs) in the critically ill.However, the time it takes to place a CVC is time a patient could potentially remain hypotensive. Early initiation of vasopressors may be associated with reduced mortality by increasing end-organ perfusion. Therefore, there has been a growing trend to use vasopressors through peripheral IVs (PIVs).  Running pressors through a peripheral IV has a couple of important benefits including faster time to pressor initiation and no need for invasive procedures (i.e. CVC). There islittle evidence to support the safety of this practice other than one systematic review which included case reports and small case series. Now we have two more papers that evaluate this very question…are peripheral pressors safe?

Background: We have discussed the safety of peripheral vasopressors on REBEL EM before. In that review by Loubani et al was a systematic review of 85 articles and 270 patients.  95% of the extravasation events occurred in PIVs with infusions running greater than 4 hours and 85% of extravasation events occurred in PIVs distal to the antecubital fossa.  The major limitation of this systematic review is that the majority of the data was derived from case reports and case series and not prospective trials.  The authors of this current study sought to determine the incidence of complications of running vasopressors through PIVs in patients with circulatory shock in a prospective, observational trial.
