# Weaning management in a patient with heart dysfunction: a case report

## TL;DR

A patient with heart dysfunction successfully weaned from ventilation using T-piece trials after initial failure, highlighting a safer approach for high-risk patients.

## Contribution

Demonstrates the use of T-piece trials to identify and manage weaning-induced pulmonary edema in patients with cardiac dysfunction.

## Key findings

- SBT-T identified WIPO risk during the second weaning attempt.
- Targeted interventions during SBT-T enabled successful extubation.
- SBT-T may improve safety in patients with heart dysfunction.

## Abstract

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.
