Pressure Supporting Ventilation & EEG-guided Emergence for Free of

Status Recruiting

Clinical Trial Summary

This study aims to assess whether pressure supporting ventilation and electroencephalogram (EEG)-guided emergence can reduce airway complications after thyroid surgery compared with conventional emergence. Patients will be randomly assigned to either pressure supporting ventilation and EEG-guided emergence group (intervention group) or conventional emergence group (control group). Co-primary outcomes are the incidence of emergence coughing and lowest percutaneous oxygen saturation (SpO2) after emergence. Secondary outcomes included severity of emergence cough, emergence time, blood pressure and heart rate during emergence, Richmond Agitation-Sedation Scale (RASS) immediately after extubation and upon post-anesthesia care unit (PACU) arrival, incidence of desaturation during PACU stay, hoarseness, sore throat during PACU stay, duration of PACU stay, surgeon satisfaction regarding emergence process, postoperative pain score, and patient satisfaction score regarding emergence process.

Clinical Trial Description

Adult patients aged < 40 years scheduled to undergo thyroid surgery will be screened for eligibility. Patients will be randomly allocate to either the intervention group or control group. - In the intervention group, pressure support ventilation will be applied from the start of subcutaneous suture until extubation. At the end of surgery, sevoflurane will be discontinued, and the attending anesthesiologist will perform tracheal extubation after observing the 'zipper opening' pattern on the EEG spectrogram, indicating the patient's recovery of consciousness. For safety reason, extubation will also be guided by the following processed EEG indices thresholds: 1. 95% spectral edge frequency (SEF) ≥ 23 2. Patient state index (PSI) ≥ 64 - In the control group, conventional full-awake extubation will be performed based on the routine practice of our institution. At the end of surgery, sevoflurane will be stopped, and the attending anesthesiologist will lead the emergence process, allowing the patient to breathe spontaneously and providing intermittent manual assistance if necessary. Extubation will be performed when the patient meets the following criteria: obeys commands such as eye-opening or hand-grip, tidal volume > 5 ml/kg, end-tidal carbon dioxide < 45 mmHg, spontaneous respiratory rate 10 to 20 breaths/min. In both groups, the Oxygen Reserve Index (ORi) will be monitored. Blinded investigator will assess the incidence of emergence coughing and the lowest SpO2 after emergence. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
