来自研究者的邀请函
Dear Colleagues,
亲爱的同事：
On behalf of the investigators of the Cuff leak and airway Obstruction in Mechanically ventilated ICU patients (COMIC) Pilot Trial, we invite you to complete an anonymous survey regarding the use of the cuff leak test (CLT) as a screening tool for laryngeal edema prior to extubation.
我们代表ICU机械通气患者套囊漏气及气道梗阻(COMIC)先导研究的研究者，邀请您完成一项有关套囊漏气试验(CLT)用于拔管前筛查喉头水肿的匿名问卷调查。
The CLT is used to screen for potential airway edema prior to extubation. A failed CLT implies that there may be laryngeal edema while a passed test implies no laryngeal edema. There are conflicting results on the actual utility and accuracy of a CLT. While one meta-analysis of observational studies found that the CLT was a specific predictor of reintubation, another meta-analysis found no such association. Recent guidelines reflect this uncertainty and a weak recommendation was issued for performing CLT in mechanically ventilated patients who are at a high risk of postextubation stridor. Data on attitude and beliefs of intensivists with regards to performing CLT are lacking.
CLT用于拔管前筛查可能出现的气道水肿。CLT失败提示存在喉头水肿，而通过CLT提示没有喉头水肿。有关CLT实际应用及其准确性的结果相互矛盾。一项观察性研究的meta分析发现，CLT是再次插管的特异性预测指标，而另一项meta分析则未能发现上述相关性。近期指南也反映了上述不确定性，对于出现拔管后喘鸣的高危机械通气患者进行CLT仅仅做出了弱推荐。尚缺乏有关ICU医生对于进行CLT的态度和可靠程度的资料。
This survey consists of 14 questions and should take you less than 10 minutes to complete. The objective of the survey is to determine national practice.
