Pinard was a pioneer of modern perinatal care and the "puericulture movement" — the teaching of infant care to expectant mothers in French obstetrics. He made a number of contributions in his work involving pre-natal and maternal health, and was an advocate of providing social care for pregnant women from deprived environments. He established abdominal obstetric palpation methods, and his name is associated with "Pinard's maneuvre", a technique used in breech extraction.
In 1895 he invented a special stethoscope for listening to fetal activity. The device is sometimes reverently referred to as a "Pinard horn", or fetoscope (although fetoscope now refers to a fetal endoscope}. Pinard horns are a safe and non-invasive tool used to listen to the fetal heart tones, and are still in use worldwide today, primarily by Midwives.
Today the Maternité Adolphe-Pinard in Nancy and the Boulevard Adolphe Pinard in Paris are named after him. This boulevard is a boundary between Paris and the city of Malakoff.
