Microdrip IV tubing creates extremely small drip sizes for medications that are potent and must be carefully administered and/or for patient populations that are highly sensitive to large doses of medications (namely, neonatal and pediatric patients). The microdrip drip factor is generally estimated at 60 gtt/mL.Macrodrip IV tubing is the more standard tubing type, and has larger drops of fluid than microdrip tubing. The macrodrip drip factor is generally somewhere between 10 and 20 gtt/mL.
