Abstract
We report the anesthetic management of microlaryngeal surgery in children using tubeless total intravenous anesthesia (TIVA) without endotracheal intubation under spontaneous breathing. In 9 patients (median age : 4.9 yr. range 1 months-14 years, body weight : 17 kg, range 3-61 kg), 19 procedures were performed with TIVA using propofol and remifentanil. The median time from the start of TIVA to rigid laryngoscope insertion was 11 minutes. Propofol 15.7 mg x kg(-1) x hr(-1) and remifentanil 0.05 μg x kg(-1) x min(-1) was infused in this interval. Laryngospasm was observed in two cases, but it responded to a bolus of propofol (0.5-1.0 mg x kg(-1)) and additional topical anesthesia with 1% lidocaine. Three children were found apneic after a bolus administration of remifentanil or after increasing the rate of remifentanil infusion accompanied with desaturation and their tracheae were intubated. The spontaneous respiration technique using TIVA without intubation provides an excellent view of the operative field while allowing stable anesthesia. Further studies are required to establish the optimal dose of propofol and remifentanil and the timing of rigid laryngoscope insertion.
