microdrip

Microdrip refers to small-volume dripping systems used in two primary contexts: intravenous therapy and drip irrigation. In medical use, microdrip typically denotes an IV administration set with a drop factor of 60 drops per milliliter (60 gtt/mL). The flow rate is calculated as (volume to be delivered in mL) × (drop factor in gtt/mL) ÷ (time in minutes), yielding drops per minute. Microdrip aims to deliver small, precise volumes, which is especially important for pediatric or neonatal patients to minimize fluid overload. Some regions also use higher drop factors, so clinicians verify the packaging.

In irrigation, microdrip (micro-drip irrigation) is a low-flow irrigation approach that uses small-diameter tubing and emitters to apply water slowly at the root zone. This method reduces evaporation, runoff, and water waste, and is commonly used for home gardens, pots, and greenhouse beds. Emission rates are typically in the low liters per hour per emitter range, and system design emphasizes uniform distribution and emitter maintenance to prevent clogging.

Although the same term is used, the two contexts differ in purpose and equipment. Users should consult device labeling or manufacturer guidelines for correct setup, safety, and maintenance. See also intravenous administration, drip irrigation, and irrigation management.
