# AI告诉旁观者通过吸入方式给予纳洛酮（Narcan）以应对阿片类药物过量，但正确途径是肌肉注射或鼻内给药

- **修复率:** 95%

## 根因

纳洛酮通过吸入吸收效果不佳；FDA批准的途径是肌肉注射（自动注射器）或鼻内喷雾（Narcan鼻喷雾）。吸入绕过鼻黏膜将药物送入肺部，属于标签外使用，可能导致误吸或剂量不足。

| Evzio Auto-Injector 2 mg | active | — | — |

## 解决方案

1. ```
   Use Narcan Nasal Spray: Insert nozzle into one nostril, press plunger firmly to deliver 4 mg dose. Repeat after 2-3 minutes if no response. Do not inhale; the spray is absorbed through nasal mucosa.
   ```
2. ```
   Use auto-injector (Evzio): Remove from case, place against outer thigh (through clothing if needed), press firmly until click. Hold for 5 seconds. Massage injection site briefly.
   ```
3. ```
   If only injectable naloxone is available, use a syringe to inject 0.4 mg (1 mL) into the anterolateral thigh muscle. Do not use inhalation.
   ```

## 无效尝试

- **Crush naloxone tablet and snort powder** — Naloxone tablets are for oral administration only; intranasal absorption of crushed powder is inconsistent and may cause nasal irritation without therapeutic effect. (90% 失败率)
- **Vaporize naloxone solution and inhale** — Heating naloxone degrades the drug; inhalation of vaporized solution can cause bronchospasm and delivers unknown dose. (95% 失败率)
- **Inject naloxone into the upper arm** — Intramuscular injection into the deltoid is less effective than the anterolateral thigh due to slower absorption; thigh is preferred for faster onset. (70% 失败率)
