侧孔抽吸式负压吸乳器的应用性研究

Study and Application of Negative Pressure Breast Pump with Side Hole

目的探讨扁平或凹陷乳头的有效矫正方法及侧孔抽吸式负压吸乳器的效果。方法将 12 2例乳头扁平或凹陷的初产妇分为三组。观察组 (38例 )用自行研制的侧孔抽吸式负压吸乳器矫正 ,对照 1组 (42例 )用一次性注射器抽吸矫正 ,对照 2组 (42例 )用市售吸乳器矫正。结果矫正后乳头伸展长度 ,乳腺管疏通数 ,吸乳器每次持续作用时间、使用次数等指标观察组与对照 1、2组比较 ,差异有显著性意义 (均P <0 .0 1)。矫正后哺乳成功率观察组与对照 1组比较 ,差异无显著性意义 (P >0 .0 5 ) ;与对照 2组比较 ,差异有显著性意义 (P >0 .0 5 ) ;矫正过程中产妇舒适度观察组与对照 1组比较 ,差异有显著性意义 (P <0 .0 1) ;与对照 2组比较 ,差异无显著性意义 (P >0 .0 5 )。结论侧孔抽吸式负压吸乳器矫正扁平或凹陷乳头的效果优于注射器抽吸和市售吸乳器矫正法 ,在使用过程中能减轻产妇痛苦 ,使产妇感觉舒适 ,乐于接受 ;矫正后产后早期哺乳成功 ,增强母乳喂养信心 ,提高母乳喂养率。

Objective To explore an effective way of correcting flat or inverted nipples and evaluate the effect of a negative pressure breast pump with side hole. Methods One hundred and twenty-two primiparas with flat or sunken nipples were divided into three group. The experimental group had 38 subjects which were treated with a home-made negative pressure breast pump with side hole. The control group I included 42 patients and their nipples were corrected by using disposable syringes. The control group Ⅱ consisted of 42 patients and their nipples were corrected by employing commercially obtained breast pumps. Results There were significant differences in the extended length of flat or sunken nipples, numbers of patent breast ducts, one-time suction time and times of using breast pump between the experimental group and control groups I and Ⅱ(P<0.01). There was no significant difference in the success rate of breast-feeding between the experimental group and control group I (P>0.05), and a significant difference was found between the experimental group and the control group Ⅱ(P<0.05). There was significant difference in comfort in the process of correction between the experimental group and the control group I (P<0.01), but no difference was noticed between the experimental group and the control group Ⅱ. Conclusion The corrective effect of our home-made breast pump is better than those of syringes and commercially available pumps. The home-made breast pump causes less pain, making it easily accepted by patients.
