Comparative Analysis of Sore Throat Incidence with and without Lidocaine Jelly Application on Endotracheal Tube Cuffs: A Prospective Study

Introduction: Sore throat is a common complication following endotracheal intubation, often attributed to mucosal irritation by the endotracheal tube cuff. Lidocaine jelly application on the cuff has been proposed as a preventive measure; however, its efficacy remains debated. Objective: This study aims to investigate the incidence of sore throat in patients undergoing endotracheal intubation, comparing cases where the cuff is coated with lidocaine jelly versus cases without such application.

Methods: A prospective study was conducted on 60 patients scheduled for elective surgeries requiring endotracheal intubation. Patients were randomly assigned to two groups: One where lidocaine jelly was applied on the cuff of the endotracheal tube and the other without such application. Sore throat incidence was assessed postoperatively at intervals using standardized scoring systems.

Results: Preliminary findings indicate that patients in the lidocaine jelly group exhibited a lower incidence of sore throat compared to the control group. Statistical analysis revealed a significant difference (p<0.05) between the two groups, suggesting the potential benefit of lidocaine jelly in reducing post-intubation sore throat.

Conclusion: The application of lidocaine jelly on the cuff of endotracheal tubes may be associated with a decreased incidence of sore throat following intubation. Further research with larger sample sizes and longer follow-up periods is warranted to validate these findings and elucidate the optimal technique and dosage of lidocaine jelly application for mitigating post-intubation complications.
