## 根因

早产儿在出生第一周因体液转移和利尿而失去出生体重的10-15%；使用出生体重给药可能导致庆大霉素或万古霉素等窄治疗窗药物过量。

## 解决方案

1. ```
   Implement a rule in the clinical decision support system that triggers an alert when dose calculation uses a weight that is more than 24 hours old, and requires the user to input the most recent weight.
   ```
2. ```
   Use a weight-based dosing calculator that automatically pulls the latest weight from the EHR and displays both birth weight and current weight for comparison.
   ```
3. ```
   For high-risk medications like aminoglycosides, require a second verification of the weight used in the calculation by a pharmacist.
   ```

## 无效尝试

- **** — Birth weight is static and quickly becomes outdated; the infant's weight changes daily in the NICU. (90% 失败率)
- **** — NICU infants often have fluid shifts, edema, or weight loss due to phototherapy or diuretics; weight must be updated daily. (80% 失败率)
- **** — Weight can change significantly in 24 hours in premature infants due to fluid management or feeding adjustments. (70% 失败率)
