Are air inlets necessary with Haemaccel?

Area of Science:

• Emergency Medicine
• Pharmacology
• Clinical Practice

Background:

• Haemaccel is a common colloid solution used for fluid resuscitation in shocked patients.
• Introducing an air inlet into Haemaccel containers is a frequent practice to enhance infusion rates.
• The clinical significance of air inlets on Haemaccel flow rates requires investigation.

Purpose of the Study:

• To quantify the impact of air inlets on Haemaccel infusion flow rates.
• To compare the efficacy of air inlets versus pressure infusion cuffs in accelerating fluid delivery.
• To evaluate the clinical relevance of flow rate changes induced by air inlets.

Main Methods:

• Comparative study analyzing infusion times for Haemaccel under different conditions.
• Tested flow rates with no air inlet, a single air inlet, a large air inlet (2x2 cm hole), and a pressure infusion cuff.
• Measured the time required to infuse standard volumes (e.g., 500 ml).

Main Results:

• Air inlets reduced the time to infuse 500 ml of Haemaccel by 27 seconds compared to no air inlet.
• This time reduction was primarily significant in the final 100 ml of infusion.
• A pressure infusion cuff was significantly faster, reducing infusion time by 68 seconds.
• Using an air inlet prevents the subsequent use of a pressure cuff.

Conclusions:

• The practice of using air inlets for Haemaccel administration provides minimal clinical benefit in resuscitation.
• Pressure infusion cuffs offer superior flow rates for rapid fluid delivery.
• Abandoning the use of air inlets in Haemaccel and similar products is recommended to optimize resuscitation protocols.
