Randomized Controlled TrialEffect of Tracheal Cuff Shape on Intracuff Pressure Change During Robot-Assisted Laparoscopic Surgery: The Tapered-Shaped Cuff Tube Versus the Cylindrical-Shaped Cuff Tube.
Although the cuff of tracheal tubes can reduce airflow leakage and prevent aspiration, excessive intracuff pressure can cause tracheal mucosal injury. Robot-assisted laparoscopic surgery (RALS) can increase intracuff pressure by the Trendelenburg position and pneumoperitoneum. The aim of our current study was to investigate the effect of tracheal cuff shape on the intracuff pressure increase by comparing two different-shaped cuffs during RALS. ⋯ The TSC tube has a tendency to decrease intracuff pressure change compared with the CSC tube during RALS. However, neither of them was beneficial in preventing intraoperative intracuff pressure increase during RALS.
