Abstract
Background
Total intravenous anesthesia (TIVA) with propofol and remifentanil is frequently used for pediatric cochlear implants (CIs) surgery as it does not suppress the electrical stapedial reflex threshold (ESRT). However, high doses of remifentanil exacerbate postoperative pain and increase opioid consumption. Intravenous lidocaine reduces pain and opioid requirement. This study investigated the effect of intravenous lidocaine on perioperative opioid consumption and ESRT in pediatric CIs.
Results
The mean (95% CI) remifentanil consumption was significantly lower in lidocaine group than in placebo group [0.57 (0.497–0.643) vs 0.69 (0.63–0.75)] μg/kg/min, = 0.016. The mean (95% CI) propofol consumption was significantly lower in lidocaine group than in placebo group [155.5 (146–165) vs 171 (161–181) μg/kg/min, = 0.02. MBP and HR were significantly lower after surgical incision, laryngeal mask airway (LMA) removal, and at PACU admission in the lidocaine group compared with the placebo group. The PACU pain score was significantly lower in the lidocaine group compared to the placebo group. The mean (95% CI) pethidine consumption in PACU was significantly lower in the lidocaine group than in the placebo group 7.0 (6.17–7.83) vs. 8.9 (7.84–9.96) mg, = 0.012. There were no differences between groups regarding ESRT response.
Conclusions
Intravenous lidocaine infusion reduced perioperative opioid requirements without altering the ESRT in pediatric CIs.
