Abstract
- Background: Tracheal tube cuff pressure will increase after pneumoperitoneum when the cuff is inflated with air, high pressure can cause tracheal mucosal damage. This prospective trial aimed to assess if inflating with normal saline or lidocaine can prevent increase of tracheal tube cuff pressure and tracheal mucosal damage in laparoscopic surgeries with general anesthesia. Whether changes of tracheal tube cuff transverse diameter (CD) can predict changes of tracheal tube cuff pressure.<br />Methods: Ninety patients scheduled for laparoscopic resection of colorectal neoplasms under general anesthesia were randomly assigned to groups air (A), saline (S) or lidocaine (L). Endotracheal tube cuff was inflated with room-temperature air in group A (n = 30), normal saline in group S (n = 30), 2% lidocaine hydrochloride injection in group L (n = 30). After intubation, tracheal tube cuff pressure was monitored by a calibrated pressure transducers, cuff pressure was adjusted to 25 cmH <subscript>2</subscript> O (T <subscript>0.5</subscript> ). Tracheal tube cuff pressure at 15 min after pneumoperitoneum (T <subscript>1</subscript> ) and 15 min after exsufflation (T <subscript>2</subscript> ) were accessed. CD were measured by ultrasound at T <subscript>0.5</subscript> and T <subscript>1</subscript> , the ability of ΔCD (T <subscript>1-0.5</subscript> ) to predict cuff pressure was accessed. Tracheal mucous injury at the end of surgery were also recorded.<br />Results: Tracheal tube cuff pressure had no significant difference among the three groups at T <subscript>1</subscript> and T <subscript>2</subscript> . ΔCD had prediction value (AUC: 0.92 [95% CI: 0.81-1.02]; sensitivity: 0.99; specificity: 0.82) for cuff pressure. Tracheal mucous injury at the end of surgery were 0 (0, 1.0) in group A, 0 (0, 1.0) in group S, 0 (0, 0) in group L (p = 0.02, group L was lower than group A and S, p = 0.03 and p = 0.04).<br />Conclusions: Compared to inflation with air, normal saline and 2% lidocaine cannot ameliorate the increase of tracheal tube cuff pressure during the pneumoperitoneum period under general anesthesia, but lidocaine can decrease postoperative tracheal mucosa injury. ΔCD measured by ultrasound is a predictor for changes of tracheal tube cuff pressure.<br />Trial Registration: Chinese Clinical Trial Registry, identifier: ChiCTR2100054089, Date: 08/12/2021.<br /> (© 2024.
