Maintaining endotracheal tube cuff pressure at 20 mmHg during anterior cervical spine surgery to prevent dysphagia: a double-blind randomized controlled trial

Purpose Anterior cervical spine surgery is associated with postoperative dysphagia, sore throatand dysphonia. It is unclear, whether this is caused by increased endotracheal tube (ETT) cuffpressure after retractorplacement. This study aims to assess the effect of ETT cuffpressure adjustment on postoperative dysphagia, sore throatand dysphonia.
