Follow-up studies of 7 to 19 months of two groups of 500 women each in Barbados, in one of which a Lippes loop had been inserted by a doctor and in the other by a nurse-midwife, showed a slightly higher incidence of pregnancy and expulsion of the loop in the second group, though the difference was not statistically significant. The insertion of loops by paramedical personnel when this is an economic necessity is thought not to be contraindicated, but adequate training is essential.
对巴巴多斯两组各500名妇女进行了7至19个月的随访研究,其中一组由医生插入利普斯节育环,另一组由助产士插入。结果显示,第二组的妊娠和节育环排出发生率略高,不过差异无统计学意义。在经济条件必要时,由辅助医务人员插入节育环被认为并非禁忌,但充分的培训至关重要。
