Lidocaine vs. Mometasone Furoate Around the Pediatric Tracheal Tube Cuff: Hemodynamic Stress Response and Postoperative Airway Complications: A Prospective, Randomized, Controlled Study.

Introduction

According to the results of the APRICOT study, airway and respiratory complications constitute 60% of all anesthesia-related complications and may be life-threatening. The primary aim of this study was to evaluate the effect of lidocaine and mometasone spray on the hemodynamic stress response during tracheal intubation and extubation in children. Our secondary aim was to determine its effect on the incidence of postoperative airway complications. Materials and

Methods

Following Ethics Committee approval (No: KIIA 2018/489) and clinical trial registration (No: NCT04085744), patient recruitment was initiated only after obtaining parental consent. Children of ASA I-II aged 0 to 16 years and undergoing elective surgery were included. A total of 91 patients were randomly divided into 3 groups. Group M: Patients treated with a topical corticosteroid 0.05% mometasone furoate spray (n = 30). Group L: Patients sprayed with 10% lidocaine (n = 30). Control group: Patients treated with 0.9% normal saline applied around the cuff (n = 31). The systolic, diastolic, and mean blood pressures, heart rate, and SpO2 values were recorded before operation, after induction, before and after tracheal intubation, and before and after extubation. Patients were followed up for 24 h postoperatively.

Results

A statistically significant decrease was found in the lidocaine group for diastolic and mean arterial pressures measured after tracheal intubation (p = 0.018 and p = 0.027, respectively). There was a significant decrease in heart rate values in Group L after extubation (p = 0.024). Cough was observed in 5 patients in the control group at the postoperative 12th hour, but not in the other groups (p = 0.009). The distribution of sore throat severity, dyspnea, and hoarseness and the incidence of early postoperative bronchospasm, recorded in all follow-up periods, decreased; however, it did not show a statistically significant difference.

Conclusions

In conclusion, this study revealed that the topical application of lidocaine and mometasone around the tracheal tube cuff in children not only reduces postoperative cough but also, in the case of lidocaine, suppresses the hemodynamic stress response during both tracheal intubation and extubation.
