吸入诱导：吸入一氧化氮加上强有力的挥发性麻醉剂（如氟烷、安氟醚或异氟醚），能在3－5分钟内诱导麻醉，诱导后可经静脉给予去极化或非去极化的神经肌肉阻滞剂，以利于气管插管。

The values of D10 and D for the total bacteria in boiled dumplings under chill state were 2.04 kGy and 4.00 kGy, the value of D10 and D for E. coli were 1.25 kGy and 2.00 kGy. TBAS were increased significantly and excessed the trade standard by 5 kGy γ-irradiation. However, the TBAS would be decreased with addition of antioxidants. Lipid peroxide,volatile basic nitrogen,"a" value of color and "b" value of color showed a tendency of increase, and moisture content and Aw showed a tendency of decrease, which did not achieve a significant level(p.05) by 1 to 5 kGy doses of γ-irradiation. Total acidity, amino acid nitrogen and free fatty acid showed no significant differences between treated and control samples. Sensory evaluation values were decreased and were all well within the acceptable level by 1 to 5 kGy doses of γ- irradiation.
