Abstract
Mid forceps were used in 4.48 per cent of all deliveries at The New York Polyclinic Medical School and Hospital during the 10 year period from 1941 through 1950. There were no maternal deaths, the gross fetal loss was 3.03 per cent (corrected to 2.27 per cent), and the maternal morbidity rate was 2.28 per cent. Included in this review are discussions on the types of forceps used, the complications encountered and the causes of fetal and infant mortality and maternal morbidity.
