Study summary

Emergence agitation is a frequent recovery complication in young children following general anesthesia with sevoflurane. It is characterized by confusion, crying, disorientation, and non-purposeful thrashing during early wakefulness, and it occurs especially often following tonsillectomy due to surgical trauma and irritation in the upper airway. The primary aim of this clinical trial is to evaluate whether preoperative administration of nebulized lidocaine reduces the incidence and severity of emergence agitation compared to normal saline in pediatric patients undergoing elective tonsillectomy under sevoflurane anesthesia.

Participants are randomly allocated into two study groups in a 1:1 ratio:

  • Group A (Lidocaine Group): Receives preoperative inhalation of 2% preservative-free lidocaine (2-4 mg/kg diluted to 4 mL) administered via a nebulizer.
  • Group B (Control Group): Receives preoperative inhalation of an identical volume (4 mL) of 0.9% normal saline placebo via a nebulizer.

Both groups receive a standardized sevoflurane-based general anesthetic. Emergence agitation is evaluated during the first 30 minutes following anesthesia cessation using the Pediatric Anesthesia Emergence Delirium (PAED) scale. Secondary outcomes evaluate postoperative pain severity (FLACC scale), rescue analgesic and sedative requirements, time to extubation, PACU length of stay, and airway-related or systemic complications.

Study arms

  • Experimental
    Group A: Nebulized Lidocaine

    Patients in this arm receive preoperative inhalation of 2% preservative-free lidocaine (2-4 mg/kg diluted to a total volume of 4 mL) administered via nebulizer prior to elective tonsillectomy under standardized sevoflurane general anesthesia.

    Drug: Lidocaine

  • Placebo comparator
    Group B: Normal Saline Control

    Patients in this arm receive preoperative inhalation of an identical volume of 0.9% normal saline (4 mL) administered via nebulizer prior to elective tonsillectomy under standardized sevoflurane general anesthesia.

    Drug: 0.9% Normal Saline

Interventions

  • Preoperative administration of 2% preservative-free lidocaine at a dose of 2 to 4 mg/kg, diluted to a total volume of 4 mL, delivered via inhalation using a nebulizer prior to elective tonsillectomy under standardized sevoflurane general anesthesia.

    Also known as: Lignocaine, 2% Preservative-Free Lidocaine, Nebulized Lidocaine

  • Drug0.9% Normal Saline

    Preoperative administration of an identical volume of 4 mL of 0.9% normal saline delivered via inhalation using a nebulizer prior to elective tonsillectomy under standardized sevoflurane general anesthesia.

What researchers measure

Primary outcomes

  1. Pediatric Anesthesia Emergence Delirium (PAED) Scale Score

    Evaluated using the Pediatric Anesthesia Emergence Delirium (PAED) scale. The scale assesses 5 behavioral items: eye contact (0-4), purposeful actions (0-4), awareness of surroundings (0-4), restlessness (0-4), and consolability (0-4). Total scores range from 0 to 20, where higher scores indicate greater severity of emergence agitation/delirium.

    Time frame: 30 minutes after anesthesia discontinuation
