This study demonstrates that tailored management of inflatable laryngeal mask airway (ILMA) cuff pressure significantly reduces postoperative pharyngolaryngeal discomfort and mucosal damage in older adults compared to empirical inflation methods. The findings suggest that individualized cuff pressure regulation can enhance patient outcomes following general anesthesia.
Background
Postoperative pharyngolaryngeal discomfort is a common complication following the use of inflatable laryngeal mask airways (ILMAs) during general anesthesia, particularly in older adults. Excessive cuff inflation can lead to increased risk of tissue ischemia and nerve damage, necessitating a more precise approach to cuff pressure management. Establishing a standardized method for monitoring and adjusting cuff pressure is crucial for improving patient comfort and reducing complications.
Tailored cuff pressure management significantly reduced pharyngolaryngeal discomfort (7.7% vs. 35.9%, p = 0.003).
Mucosal damage was absent in the RM group compared to 15.4% in the EI group (p = 0.011).
Cuff pressure was significantly higher in the EI group compared to the RM group (p < 0.001).
No significant differences in ILMA positioning precision or ventilation seal efficacy between groups (p > 0.05).
Postoperative discomfort was primarily noted during the initial postoperative phase.
Clinical Implications
The findings underscore the importance of monitoring and adjusting ILMA cuff pressure to minimize postoperative complications in older adults. Implementing a tailored cuff pressure management protocol may enhance patient comfort and reduce the incidence of pharyngolaryngeal discomfort and mucosal injury.
Conclusion
Tailored management of ILMA cuff pressure is a viable strategy to improve postoperative outcomes in older patients undergoing general anesthesia, highlighting the need for standardized cuff pressure monitoring in clinical practice.
