为研究一侧鼻腔容积的变化对另一侧鼻腔容积的影响,选择鼻腔正常者18例,分为两组作声鼻腔测量实验。在隔音室内取坐位,用声鼻腔计各自在特定的实验条件下,分别于即刻,3,6,9分钟后,左右各3次(计24次)测定鼻腔容积的变化。实验Ⅰ组男9例,女1例,年龄26～49岁(平均30岁)。用鼻片作鼻栓,将其阻塞一侧鼻腔,测定另一侧鼻腔容积的变化,然后交替测定。实验Ⅱ组男5例,女3例,年龄24～34岁(平均29岁)。一侧鼻腔粘膜用血管收缩剂(0.1‰肾上腺素或0.05％萘甲唑啉)作用10分钟后,测定鼻腔容积增加时另一侧鼻腔容积的变化。实验分3天进行。第1天作对照测定后,接着用血管收缩剂使右鼻腔粘膜收缩时,测定两侧鼻腔容积的变化。第2天按同法使左鼻腔收缩后测定两侧鼻腔容积的变化。第3天用盐水棉球插入右总鼻道10分钟后,测定两侧鼻腔容积的变
In order to study the change of nasal volume on the other side of the nasal cavity volume, select the normal nasal cavity in 18 cases, divided into two groups for nasal test. Take the sitting position in the soundproof room, and measure the change of the nasal cavity volume with the nasal cavity meter under the specific experiment condition immediately after 3, 6, and 9 minutes respectively, about 3 times (about 24 times). In experiment group I, there were 9 males and 1 females, aged 26-49 years old (average 30 years old). Using a nose piece as a nose plug, blocking the nasal cavity on one side, measuring changes in nasal volume on the other side, and then alternatingly determining. In experiment Ⅱ, there were 5 males and 3 females, aged from 24 to 34 (average 29 years old). One side of the nasal mucosa with vasoconstrictor (0.1 ‰ epinephrine or 0.05% naphazoline) for 10 minutes after the determination of nasal volume increases on the other side of the nasal volume changes. The experiment was conducted in 3 days. After the first day as a control, the right nasal mucosa was contracted with a vasoconstrictor, and the change of the nasal cavity volume on both sides was measured. On the second day, according to the same method, the left nasal cavity was contracted to measure the nasal cavity volume changes on both sides. On the third day, saline nasal swabs were inserted into the right common nasal passages for 10 minutes to measure changes in nasal volume on both sides
