\*\*Intervention Description:\*\* Nebulized ketamine is administered as a single dose of 0.5 mg/kg of ketamine hydrochloride diluted in 0.9% normal saline to a total volume of 5ml. The solution is delivered via a standard jet nebulizer over approximately 15-20minutes. This intervention is given once at the time of enrollment in the emergency department, in addition to standard asthma care. The ketamine used is in injectable solution form (typically 50 mg/mL concentration), drawn and diluted immediately prior to nebulization. Participants are monitored continuously for 60 minutes after administration to assess changes in peak expiratory flow rate (PEFR), symptom relief, and adverse events. The goal is to evaluate the bronchodilatory effect and safety of nebulized ketamine in adults with moderate to severe asthma exacerbation who present to the emergency department.
\*\*Intervention Description (Control Group):\*\* Participants in the control group will receive a single nebulized dose of 5 mL of 0.9% normal saline, delivered using a standard jet nebulizer over approximately 10-15 minutes. This placebo intervention is administered once at the time of enrollment in the emergency department, after standard asthma care. Standard care includes repeated doses of nebulized salbutamol and ipratropium, systemic corticosteroids (oral or intravenous), and supplemental oxygen as needed. The placebo solution is identical in appearance and volume to the active ketamine solution used in the intervention group to maintain blinding. All participants will be monitored for 60 minutes after nebulization to assess changes in peak expiratory flow rate (PEFR), symptom relief using a visual analog scale (VAS), and the occurrence of any adverse events.

研究简介（原文）
The goal of this clinical trial is to learn if nebulized ketamine helps treat moderate to severe asthma attacks in adults in the emergency department. It will also learn about the safety of ketamine when inhaled through a nebulizer. The main questions it aims to answer are: * Does nebulized ketamine improve breathing more than standard treatment alone? * What side effects, if any, do participants experience after receiving nebulized ketamine? Researchers will compare nebulized ketamine to a placebo (a saltwater mist with no medication) to see how well it works and how safe it is. Participants will: * Receive either nebulized ketamine or a placebo mist, along with standard asthma treatment * Have their breathing checked before and after treatment using a peak flow meter * Be monitored for 60 minutes and have their symptoms, vital signs, and any side effects recorded

这项试验目前在中国大陆没有研究中心
这种情况下，直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药／扩展准入（由主治医生一同提出），或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
