PURPOSE: Rapid volume resuscitation is a mainstay of therapy for distributive or hypovolemic shock. The Hagen-Poisseuille equation dictates that infusion rates will be significantly affected by the length and internal diameter of the intravenous (IV) access devices utilized. We sought to assess the in-vitro infusion rate of normal saline through various IV access devices with a pressure infusion device (PID).

METHODS: IV access devices assessed included: 22 gauge peripheral IV (PIV); 20 gauge PIV; 18 gauge PIV; 16 gauge PIV; 18 gauge “Power PICC”, 17 gauge “Power PICC”; 16 cm/18 gauge triple lumen catheter (TLC); 20 cm/16 gauge triple lumen catheter (TLC); 16 cm/16 gauge triple lumen catheter (TLC); 20 cm/16 gauge double lumen catheter; peripheral rapid infuser catheter; 7 Fr cordis introducer. 1 Liter of normal saline was infused through each peripheral access device using a PID set at 300 mmHg pressure. Three trials through each catheter were performed.

RESULTS: The total infusion time and mean infusion rate (mL/min)for the various devices are summarized in the table (not published).

CONCLUSION: Large differences between infusion flow rates exist for different IV access devices. This study confirms the impact of device length and internal diameter on infusion rates and provides clinicians with an estimate of actual infusion rate.

CLINICAL IMPLICATIONS: Two large bore (16 gauge or larger) peripheral IVs offer the most rapid rate of infusion. A single peripheral rapid infuser catheter may represent an underutilized alternative to cordis placement. Further study of in vivo infusion rates comparing these techniques is warranted.
