Patients undergoing weaning from mechanical ventilation face the risks of reintubation. Spontaneous breathing trials (SBTs), including T-piece (SBT-T) and pressure support (SBT-P), are commonly used to assess extubation readiness. Current guidelines favor the use of SBT-P. Weaning-induced pulmonary edema (WIPO) is common after extubation, which could lead to extubation failure.
We report the case of a patient on ventilation who failed the first extubation attempt following successful SBT-P due to WIPO. SBT-T was implemented for the patient in the second weaning attempt.
During the subsequent SBT-T, signs of WIPO recurred. Instead of terminating the trial, we managed the patient with intensive monitoring, fluid management, and blood pressure control.
After targeted interventions, this patient was successfully extubated during the second weaning attempt.
This case highlights the utility of SBT-T in unmasking WIPO risk in weaning patients with cardiac dysfunction. By enabling proactive management during the trial, SBT-T may enhance safety in high-risk populations.
接受机械通气撤机的患者面临再次插管的风险。自主呼吸试验(SBTs),包括T管试验(SBT-T)和压力支持试验(SBT-P),常用于评估拔管的准备情况。当前指南倾向于使用SBT-P。撤机诱发的肺水肿(WIPO)在拔管后很常见,这可能导致拔管失败。
我们报告了一例接受通气治疗的患者,在成功完成SBT-P后首次拔管尝试因WIPO而失败。在第二次撤机尝试中对该患者实施了SBT-T。
在随后的SBT-T期间,WIPO的体征再次出现。我们没有终止试验,而是通过强化监测、液体管理和血压控制对患者进行处理。
经过针对性干预,该患者在第二次撤机尝试期间成功拔管。
本病例突出了SBT-T在揭示心脏功能不全撤机患者WIPO风险方面的作用。通过在试验期间进行积极管理,SBT-T可能提高高危人群的安全性。
