Should small syringes be used for feeding tube flushes? Why?

• A. Yes, because they allow precise dosing
• B. Yes, because smaller syringes generate higher pressure
• C. No, increased pressure exerted by a small syringe may cause feeding tube rupture
• D. No, because they take longer to flush

Answer: (C)

When flushing a feeding tube, syringe size matters because pressure delivered to the tube depends on the syringe’s size. A small syringe concentrates the same flush volume into a much smaller plunger area, so pushing it quickly creates higher intraluminal pressure. That elevated pressure can stress or rupture the feeding tube, especially if the tube is delicate or placed for a long time. Using a larger syringe, like a 60 mL syringe, distributes the force over a bigger area and allows a gentler, safer flush, reducing the risk of damage while still clearing the lumen.

Other ideas aren’t the main safety issue here: the notion that small syringes provide precise dosing isn’t the key factor in tube safety, and the concern isn’t primarily about how long a flush takes but about the pressure generated and potential tube injury.
