Abstract: (66 Views)
Background: Intubation is normally conducted in an emergency or prior to surgery. A cuffed tracheal tube is fitted, whose inflated cuff exerts pressure on the tracheal wall. Such pressure should, therefore, be monitored every day by use of pressure gauge devices. The general guideline in this regard is that the pressure of the cuff must lie between 20 and 30 cm of water. The exaggerated pressure may cause tissue ischemia, wound, and necrosis of the tracheal wall; if it is too low, this could result in air leakage and oropharyngeal secretions, increasing the risk of insufficient ventilation and aspiration pneumonia. This study aimed at comparing the cuff pressure of an endotracheal tube inflated with alkaline lidocaine versus air for any post-extubation complications and cuff pressure changes.
Methods: This prospective cohort study was conducted on patients who were admitted to the intensive care unit of Baqiyatullah Al-Azam Hospital in Tehran between May 2023 and February 2024, underwent intubation in this unit and met the inclusion criteria for the study. This prospective study included 62 patients, and tracheal tube cuff pressure was recorded at 30 minutes, 60 minutes, 120 minutes, 6 hours, and 24 hours after intubation with a pressure gauge. Patients were randomly divided into two groups-an 'air group', whose cuff was inflated to the pressure of 20 cmH2O by air, and a 'lidocaine group,' whose cuff was filled with 2% lidocaine to the same pressure. In this study, the post-extubation complications, such as sore throat, hoarseness, and cough, were assessed immediately and 24 hours after extubation. Similarly, the tracheal tube displacement during the intubation process was monitored in both groups.
Results: The results showed that the pressure of an endotracheal tube cuff inflated with lidocaine was drastically lower than the one inflated with air, with a p-value of 0.001. On the other hand, the sore throat, cough, and hoarseness after extubation and 24 hours later were significantly fewer in the lidocaine group compared with the air group at a p-value of 0.001.
Conclusion: Cuffs inflated with alkalinized lidocaine clearly avoided high cuff pressure at induction and reduced postextubation sore throat. Hence, alkalinized lidocine-filled endotracheal tube cuffs are comparatively safer and more beneficial than conventional air-filled cuffs.
