【摘要】 目的 探讨产后哺乳妇女首次排卵时间与婴儿喂养的关系,为哺乳妇女采取避孕措施提供科学依据。方法 对101 例哺乳妇女进行B超监测排卵,并结合基础体温测量及宫颈粘液评分进行连续观察;记录哺乳妇女的月经复潮时间和婴儿添加辅食的时间。结果 (1) 通过B超监测发现,101 例哺乳妇女中,有53 例(52-5% ) 平均在产后154 天(5-1 个月) 监测到直径> 1-8 cm 的成熟卵泡。产后4 个月内首次排卵者11 例(10-9 %) ,4 个月后首次排卵者42 例(41-6% ) 。(2) 排卵者基础体温测量均呈双相,但多数高温相<10 天。(3)53 例排卵者宫颈粘液评分总分为6 ~11 分。(4) 婴儿添加辅食的时间为平均4 个月,与月经复潮时间及首次排卵时间呈显著正相关。结论 产后哺乳妇女自行选择避孕措施的具体实施,应在产后4 个月开始,延长母乳喂养的时间是避孕的一种有效方法。添加辅食开始时间早于4 个月时,对产后月经复潮及排卵有较大影响。
