    AbstractActivated charcoal is often given through small-bore tubing for pediatric patients or in attempts to bypass the stomach in patients who are vomiting. The viscosity makes activated charcoal difficult to administer through small-bore tubing. This in vitro study examined several interventions to facilitate flow of aqueous suspension activated charcoal through the small-bore tubing. Aqueous suspension activated charcoal with or without sorbitol had similar flow rates. Precoating the tubing with mineral oil gave only minimal increases in flow rate. A 10% dilution decreased the time to administer 240 ccs of aqueous suspension activated charcoal by 2/3. An additional 10% dilution reduced the time to administer the same dose a further 50%. Minimal dilution of aqueous suspension activated charcoal with tap water greatly increased flow rate through small-bore tubes.
