Ambroise Paré

Ambroise Paré was a highly influential French barber-surgeon who lived during the 16th century.

He is widely recognized as one of the fathers of surgery and a pioneer in modern forensic pathology. Forensic pathology is the study of how the body changes after death, often to help solve legal questions. Paré served four different French kings: Henry II, Francis II, Charles IX, and Henry III. Throughout his career, he focused on improving battlefield medicine and surgical techniques. He was a dedicated anatomist and an inventor of new medical instruments. His work helped transition medicine from old traditions toward evidence-based practice.

Paré's approach to medicine relied on careful observation rather than following old beliefs.

During a military campaign, he tested a new way to treat gunshot wounds. The traditional method involved cauterization, which meant searing wounds with boiling elder oil. Paré observed that soldiers treated with boiling oil suffered extreme agony. Instead, he tested a recipe consisting of egg yolk, oil of roses, and turpentine. He discovered that the turpentine acted as an antiseptic to help prevent infection. The soldiers treated with this ointment recovered much better than those who were cauterized. This discovery led him to avoid the use of boiling oil for wounds.

In addition to wound care, Paré made major breakthroughs in how surgeons handle bleeding. During amputations, the standard practice was to use a red-hot iron to seal wounds. This method often failed to stop the bleeding and caused patients to die from shock. Paré reintroduced the use of the ligature of arteries. A ligature is a way of tying off a blood vessel to stop blood flow. To assist with this, he designed a tool called the "Bec de Corbeau," or crow's beak. This device was an early predecessor to modern haemostats, which are tools used to control bleeding. Although ligatures could sometimes spread infection, they were a vital improvement for surgical safety.

Paré's career was marked by many unique medical observations and experiments. In 1542, during the siege of Perpignan, he helped solve a difficult bullet extraction. A soldier had a bullet lodged in his shoulder that was hard to find. Paré instructed the man to mimic the exact physical position he held when he was shot. This allowed the surgeon, Nicole Lavernault, to locate and remove the bullet. In 1567, Paré conducted an experiment regarding bezoar stones. Many people believed these stones could cure any poison. Paré tested this by observing a cook who was poisoned. The cook took a bezoar stone but died seven hours later, proving the stone was not a universal cure.

He also made significant contributions to the field of obstetrics, which is the branch of medicine dealing with childbirth. Paré revived the practice of podalic version. This is a technique used to help deliver an infant safely by turning the baby during birth. Before this, surgeons sometimes had to use much more violent methods to extract an infant. Paré's work in this area influenced the education of important figures, such as the royal midwife Louise Boursier. He also introduced the practice of lancing an infant's gums during teething. He believed that teeth could not emerge without a pathway, a theory that remained in use for centuries.

Paré was also an innovator in the field of prosthetics and ocular care. He designed artificial limbs to help patients who had undergone amputations. He also created ocular prostheses, which are artificial eyes, made from materials like enameled gold, silver, porcelain, and glass. His studies extended to the neurological aspects of surgery as well. He documented the phenomenon of phantom limb pain. This is the sensation where an amputee feels pain in a limb that is no longer there. Paré correctly believed that these sensations occurred in the brain rather than in the remaining part of the limb.

Paré's life was also shaped by the religious tensions of his time. He was a Huguenot, a member of a French Protestant group. During the St. Bartholomew's Day Massacre in 1572, his life was saved when King Charles IX locked him in a clothes closet. To avoid further danger, Paré often maintained the appearance of being Catholic. He was twice married and had his children baptized in the Catholic faith. He lived to the age of 80 and died of natural causes in Paris in 1590. His legacy is honored today by the asteroid 259344 Paré, discovered in 2003.
