通过对８３例分娩后１－４天的哺乳期妇女予催产素注射液滴鼻，并设对照组（生理盐水滴鼻）进行效果观察。结果表明：催产素滴鼻的乳母较滴生理盐水液的乳母泌乳始动时间提早（ｘ２＝１４．８２，Ｐ＜０．０１），且泌乳量明显增多（ｘ２＝１６．４７，Ｐ＜０．０１）。Ｂ超下显示：滴鼻后１０分钟测左乳腺腺管直径为０．４８７２±０．０８３ｃｍ，左侧乳腺腺管直径用药前、后比较ｔ＝１４．０８，Ｐ＜０．０１。而对照组乳腺腺管直径用药前后比较，Ｐ＞０．０５，无显著差异。说明催产素滴鼻后使乳腺腺管明显扩张，肌上皮收缩，从而起促泌乳作用。此法方便安全，无副作用，可在临床推广使用。
Through the 83 cases of 1-4 days after delivery lactating women to oxytocin nasal drops, and the control group (saline drip) for observation. The results showed that oxytocin nasal lactation started earlier (x2 = 14.82, P <0.01), and lactation volume increased significantly (x2 = 16.47, P <0) .01). B ultrasound showed that the diameter of the left breast duct was 0.4872 ± 0.083 cm 10 minutes after the nasal drops, the diameter of the left breast duct was t = 14.08 before and after treatment, P <0.01. The control group breast duct diameter before and after treatment, P> 0.05, no significant difference. Oxytocin intranasal injection of oxytocin significantly expand the ducts, myoepithelial contraction, which played a role in promoting lactation. This method is convenient and safe, no side effects, can be used in clinical promotion.
