Abstract

Purpose Aspiration is a feared complication that may occur during airway management, and can significantly contribute to morbidity and mortality. Availability of a suctioning device with a suction catheter capable of clearing the airway is mandatory for airway management. However, suction performance may be significantly different amongst different suction catheters. The aim of this study was to compare suction rates of a standard 14 Ch suction catheter (SC), a Yankauer catheter (Y) and a DuCanto catheter (DC) using 4 fluids with different viscosity. Methods In this simulation trial, 4 preparations with standardized viscosity were prepared using a Xanthane-based medical fluid thickener. Lowest viscosity was achieved using tap water without thickener, syrup-like viscosity was achieved by adding 10 g per liter tap water, honey-like viscosity was achieved by adding 20 g per liter, and a pudding-like viscosity was achieved by adding 30 g of thickening powder per liter tap water. Each preparation was suctioned for 15 s with the three different suctioning devices. Measurements were repeated four times. The amount of removed preparation by suctioning was measured using a tared scale. Results Suction rates for water were 580 +/- 34 mg for SC, 888 +/- 5 mg for Y and 1087 +/- 15 for DC; for syrup-like viscosity it was 383 +/- 34(SC) vs. 661 +/- 64(Y) vs. 935 +/- 42(DC); for honey-like viscosity it was 191 +/- 21(SC) vs. 426 +/- 34(Y) vs. 590 +/- 68(DC); and for pudding-like viscosity 74 +/- 13(SC) vs. 164 +/- 6(Y) vs. 211 +/- 8(DC). Conclusion Suctioning liquids of different viscosity, the new DuCanto catheter was more effective than the Yankauer catheter that was more effective than a standard suctioning catheter. The relative superiority of the DuCanto was highest in fluids with high viscosity.
