Comparison Of Two Anesthesia Methods With And Without The Use Of Lidocaine Spray On The Incidence Of Laryngospasm After Extubation In Children Undergoing Tonsillectomy: A Descriptive-Analytical Study

Background: Controlling complications after tonsillectomy surgery is one of the important issues of anesthesia in these patients. Laryngospasm is one of the most serious complications that can lead to hypoxia and arterial hypercarbia following airway obstruction, and if not treated correctly and on time, it can cause dangerous and irreparable consequences for the patient. Therefore, this study was conducted with the aim of comparing two anesthesia methods with and without the use of lidocaine spray on the incidence of laryngospasm after extubation in children undergoing tonsillectomy surgery. Method: In this descriptive-analytical study, ۱۴۰ children referred for tonsillectomy surgery in the operating room of ۵ Azar Hospital in Gorgan and Amiralmomenin Hospital of Kordkuy  in ۲۰۲۱ were randomly selected. Patient were anesthetized by one of two methods of anesthesia using lidocaine (in the form of local spray) or without using lidocaine. Results: In this study, ۶۶ patients who were anesthetized with lidocaine and ۷۴ patients who were anesthetized without lidocaine. ۱۲ patients (۸.۵۷%) had laryngospasm. ۱۲ patients, ۱۰ cases (۱۳.۵%) were in the anesthesia group without lidocaine, and ۲ cases (۳.۰۳%) were in the anesthesia group with lidocaine, which according to the prevalence of laryngospasm in these two groups (۱۳.۵% compared to ۳.۰۳%) The difference between these two groups was significant (P<۰.۰۵). Conclusion: The results of the present study showed that the effect of lidocaine on the occurrence of laryngospasm and the occurrence of straining on the tube had a significant difference between the two groups and was less in the group where lidocaine was used. But regarding the incidence of cough, despite its lower incidence in the lidocaine group, it was not statistically significant.
