# AI编程胰岛素泵时使用了忽略昼夜节律胰岛素敏感性的24小时基础率方案，导致1型糖尿病患者夜间低血糖

- **ID:** `medical/insulin-pump-basal-rate-circadian`
- **领域:** medical
- **类别:** config_error
- **错误码:** `PUMP-BASAL-ERR-03`
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

AI设置了24小时恒定基础率（如0.8 U/h），未考虑黎明现象（3-8 AM胰岛素需求增加）和夜间胰岛素敏感性（12-3 AM需求减少），导致凌晨2-3点低血糖。

## 解决方案

1. ```
   Program a multi-step basal profile: 12 AM-3 AM: 0.5 U/h, 3 AM-8 AM: 1.0 U/h (dawn phenomenon), 8 AM-12 PM: 0.8 U/h, 12 PM-6 PM: 0.7 U/h, 6 PM-12 AM: 0.6 U/h. Validate with 3-day CGM data.
   ```
2. ```
   Use the pump's built-in 'Basal Pattern' feature to create a 'Night Safe' pattern with reduced rate 12-3 AM. Set low-glucose suspend threshold at 70 mg/dL. Train patient on pattern switching.
   ```
3. ```
   Implement an algorithm in the pump management software that adjusts basal rates based on historical CGM data and circadian models. Example: 'AutoBasalCircadian' script that analyzes 14-day glucose patterns.
   ```

## 无效尝试

- **** — Uniform reduction may still cause nocturnal hypoglycemia if the rate during 12-3 AM is still too high, and may cause daytime hyperglycemia. (70% 失败率)
- **** — This ignores the dawn phenomenon; the rate may be too low for 3-8 AM, causing hyperglycemia upon waking. (65% 失败率)
- **** — This removes a critical safety feature that can prevent severe hypoglycemia; the root cause (incorrect basal profile) remains unaddressed. (90% 失败率)
