Abstract:
Background
Flexible laryngeal mask airway may be used instead of the endotracheal tube in children presented for elective repair of tongue trauma, as it may shorten the time for extubation and recovery with the amelioration of stress response to airway management.
Objectives
This study aimed to evaluate the extubation time and hemodynamic response to the endotracheal tube or flexible laryngeal mask airway in children presented for tongue trauma repair.
Methods
The study recruited 90 children presented for elective repair of tongue trauma that were randomly assigned into the following groups: the ETT group for which the airway was controlled by a cuffed endotracheal tube and the LMA group for which the airway was controlled by a flexible laryngeal mask. The intubation time, surgical time, total anesthesia time, extubation time, recovery time, changes in the hemodynamic parameters, and the incidence of complications were measured.
Results
The use of flexible laryngeal mask airway instead of endotracheal tube significantly decreased the extubation time to 7.47 ± 2.74 min (P < 0.0001) and the recovery time to 52.67 ± 11.16 min (P = 0.001) while no significant differences were observed in the intubation time (P = 0.874), surgical time (P = 0.411), and total anesthesia time (P = 0.725). In addition, the changes in the hemodynamic parameters were significantly lower with flexible laryngeal mask airway both during airway securing and at the start of the surgery (P < 0.05). Moreover, it significantly decreased the incidence of postoperative cough, stridor, and sore throat (P = 0.039, 0.006, and 0.027, respectively).
Conclusions
The flexible laryngeal mask airway can be used instead of the endotracheal tube in children undergoing the repair of tongue trauma, as it decreases the extubation time, recovery time, and hemodynamic changes to the airway control.
