本文对33例因鼻阻需行鼻中隔矫正、下甲切除的患者,手术前充分涂布1:5000肾上腺素后和手术后,分别测定双侧、右侧、左侧在鼻呼吸时的阻抗值,并以20例健康者作对照。所获结果以双侧值为例:术前平均值6.7±2.7cmH_2O/L/秒;涂肾上腺素后平均值4.1±0.8cmH_2O/L/秒;术后平均值3.8±0.9cmH_2O/L/秒;健康者平均值4.2±0.6cmH_2O/L/秒。涂肾上腺素后两侧鼻呼吸阻抗值降低者31例,与术前相比变化率为34.9±18.5％。术后两侧鼻呼吸阻抗值降低者31例,与术前相比变化率为39.4±17.8％。
In this paper, 33 cases of nasal obstruction due to nasal septum correction, subcarpal excision of patients before surgery fully coated with 1: 5000 epinephrine and after surgery were measured in the bilateral, right, left impedance in the nasal respiratory resistance , And 20 healthy people as control. The results obtained with the bilateral values as an example: preoperative mean 6.7 ± 2.7cmH_2O / L / sec; after epinephrine average 4.1 ± 0.8cmH_2O / L / sec; postoperative average 3.8 ± 0.9cmH_2O / L / sec ; Healthy average 4.2 ± 0.6cmH_2O / L / sec. Twenty-one cases of nasal respiratory resistance decreased after adrenaline administration, with a change rate of 34.9 ± 18.5% compared with that before operation. Thirty-one patients had nasal respiration resistance reduction on both sides, which was 39.4 ± 17.8% compared with that before operation.
