Abstract:
Three-way laryngeal mask airway (tLMA) was used in 31 patients aged 4-68 yr, weighing 10- 79 kg undergoing tracheal foreign body removal under general anesthesia. Anesthesia was induced with propofol 3 mg/kg, vecuronium 0.12 mg/kg and remifentanil 0.4 μg/kg. tLMA was inserted. The patients were mechanically ventilated. Anesthesia was maintained with iv infusion of propofol 2 mg . Kg-1 ? H-1, vecuronium 0.08 mg·kg-1·h-1 and remifentanil 0.15 μg·kg-1 ·min-1 . Radial artery was cannulated for BP monitoring and blood sampling. The operation time was 6-34 min and mechanical ventilation time 19-45 min. There was no significant change in SP, DP, HR, VT, Ppeak and Ppeak CO, during operation as compared with the baseline values before anesthesia. SpO2 was significantly increased at T2-6. PCO2, PO2 and O2sat were obviously improved after tLMA was used. All the patients emerged bom anesthesia within 30 min after operation. No aspiration, obvious gastrointestinal inflation, and pharyngeal and laryngeal edema and injury occurred. Mild agitation occurred in a short time during the recovery period in one patient. No complication occurred.
