Insertion of Lippes loop by nurse-midwives and doctors

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.
