# AI告诉旁观者通过吸入方式给予纳洛酮（Narcan）治疗阿片类药物过量，但正确途径是鼻内喷雾或肌肉注射；吸入无证据且可能加重呼吸抑制

- **修复率:** 95%

## 根因

纳洛酮配制成鼻喷雾剂（如Narcan 4 mg）或注射剂（IM/IV）；通过雾化器或蒸发器吸入未获FDA批准，剂量不可预测，且在呼吸骤停时延迟吸收。

## 解决方案

1. ```
   Administer Narcan nasal spray: insert nozzle into one nostril, press plunger firmly. If no response after 2-3 minutes, give second dose in other nostril. Call 911 immediately.
   ```
2. ```
   If trained, give intramuscular naloxone (0.4-2 mg) into thigh (vastus lateralis) using auto-injector or syringe. Example: Evzio auto-injector follows voice prompts.
   ```
3. ```
   If no naloxone available, perform rescue breathing (1 breath every 5 seconds) and wait for EMS; do not attempt inhalation methods
   ```

## 无效尝试

- **** — Narcan tablets are for injection only; snorting causes nasal irritation and unpredictable absorption; no evidence of efficacy (95% 失败率)
- **** — Nebulized naloxone is not standard; most EMS protocols do not allow it; absorption is slow and may not reverse overdose in time (90% 失败率)
- **** — Heat degrades naloxone; no data on efficacy; may cause thermal injury to airway (98% 失败率)
