Decreasing the pressure of endotracheal tube cuff slowly with a constant speed can decrease coughing incidence during...

Area of Science:

• Anesthesiology
• Critical Care Medicine
• Surgical Procedures

Background:

• Coughing during extubation is a common adverse event.
• Endotracheal tube cuff pressure management is crucial for patient safety.
• Investigating methods to mitigate extubation-related complications.

Purpose of the Study:

• To evaluate the efficacy of slow, controlled endotracheal tube cuff pressure deflation in reducing coughing during extubation.
• To compare the incidence of coughing and adverse reactions between slow and rapid cuff deflation techniques.
• To assess the impact of different deflation methods on hemodynamic stability.

Main Methods:

• A randomized controlled trial involving 90 patients undergoing noncardiac surgery.
• Patients were divided into two groups: slow deflation (3 cmH2O/s) and rapid deflation.
• Coughing incidence, hemodynamic parameters (MAP, HR), and adverse reactions were recorded.

Main Results:

• The slow deflation group showed a significantly lower incidence of coughing during extubation (P=0.001).
• Hemodynamic parameters (MAP, HR) were more stable in the slow deflation group post-extubation (P<0.05).
• Pharyngolaryngeal discomfort was significantly reduced in the slow deflation group (P=0.021).

Conclusions:

• Slowly decreasing endotracheal tube cuff pressure is an effective strategy to minimize coughing during extubation.
• This technique promotes hemodynamic stability and reduces the occurrence of adverse events post-extubation.
• Controlled cuff pressure management offers improved patient outcomes after general anesthesia.
