Two infants. The same weight.

1.8 kg
Born at 26 weeks
Now 34 weeks postmenstrual age
1.8 kg
Born at 34 weeks
One day old
Same weight, same milligrams per kilogram. They do not clear a renally eliminated drug at the same rate.

Rhodin et al. (2009), Pediatric Nephrology

The principle

The clock is not the birthday.

Maturity, not weight and not the calendar, governs how a newborn handles a drug. Two charts can read identically while the kidneys behind them are weeks apart.

PMA = gestational age at birth + postnatal age
The method

Ten seconds. Read it back.

Before the dose reaches the baby, four things get said out loud, every time:

the dose
the interval
the volume
the syringe

“Ten seconds to read it back is never time you lose.”
