Effect of Early use of in-line speaking valve on time to wean from mechanical ventilation in Intensive Care Unit patients with tracheostomies: a pilot randomised controlled trial

Patients in intensive care who need long-term help breathing may have a tracheostomy — a small opening in the throat to support ventilation. Weaning patients off the mechanical ventilator is an important goal, but it takes time. Speaking valves are small one-way devices that can be fitted into the ventilator circuit to allow air to flow through the upper airway during breathing out, enabling the patient to speak. Some research suggests these valves may also help patients wean off the ventilator faster. This pilot study is testing whether introducing a speaking valve early — within 72 hours of a tracheostomy — is safe and leads to shorter time on the ventilator and better communication compared to standard care. The primary aim is to establish whether a larger definitive trial is feasible and safe. You may be eligible if you are 18 or older, are a patient in an ICU with a tracheostomy in place, are mechanically ventilated but able to breathe spontaneously, can follow simple commands, and are expected to remain in the ICU for at least another day. Patients who need heavy sedation, very high ventilator settings, or who have severe airway obstruction are not eligible. The study is run at Sir Charles Gairdner Hospital.
