Root Cause

Dopamine infusion rates for neonates require weight-based dosing in mcg/kg/min, but AI incorrectly applies adult fixed-rate calculations (e.g., 5-20 mcg/kg/min for adults vs. 2-10 mcg/kg/min for neonates), leading to a twofold or greater overdose risk.

新生儿多巴胺输注速率需要基于体重的微克/公斤/分钟剂量计算，但AI错误地应用成人固定速率计算（例如成人5-20微克/公斤/分钟 vs 新生儿2-10微克/公斤/分钟），导致两倍或更高的过量风险。

Workarounds

  1. 92% success Use the neonatal dopamine infusion calculator: dose (mcg/kg/min) × weight (kg) × 60 (min/hr) ÷ concentration (mcg/mL) = rate (mL/hr). For a 3 kg neonate requiring 5 mcg/kg/min from a 1600 mcg/mL solution (40 mg in 25 mL D5W), rate = 5 × 3 × 60 / 1600 = 0.56 mL/hr.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Adult nomograms assume higher baseline blood pressure and different receptor sensitivity; applying them to neonates can cause hypertension, tachycardia, and extravasation injury.

  2. 65% fail

    Neonates lose weight after birth and then regain; using birth weight leads to underdosing or overdosing depending on day of life.

  3. 75% fail

    Fixed rate without concentration adjustment ignores the required mcg/kg/min target, leading to therapeutic failure or toxicity.
