本研究结果显示,撤机成功组的SBT 30 min右侧DE和DTF高于撤机失败组,差异均有统计学意义(P<0.05),提示良好的膈肌功能是撤机的保障。以SBT 30 min 时右侧DE和DTF行ROC曲线预测撤机成功的AUC分别为0.91和0.87,右侧DE以1.23 cm为临界值,灵敏度为82.4%,特异性为57.8%;DTF以0.265为临界值,灵敏度为80.9%,特异性为71.3%。提示超声评价患者膈肌功能对机械通气撤机成功具有重要作用。

综上所述,本研究通过分析旁超声评价膈肌功能预测撤机结果的价值,能以更快捷、安全、经济、方便、直观的超声技术评估撤机前患者的膈肌功能,通过探讨患者撤离呼吸机成功与膈肌功能之间的联系,使超声评估膈肌功能成为撤机的指导指标,与RSBI、P 0.1等传统撤机指标联合,便于对机械通气撤机进行更好的指导,从而提高撤机成功率。并对床旁超声技术评估患者膈肌功能进行推广,便于早期识别膈肌功能障碍。
