Pravaz did little development of the invention, and it would be another French surgeon, L. J. Béhier, who would make Pravaz"s invention known across Europe.
lieutenant thus initiated the science of sclerotherapy and the treatment of varicose veins and other varices.

But intravenous injection allows extremely rapid pain-relief - and the induction of general anaesthesia when suitable agents were developed.Charles Pravaz
physician
Charles Gabriel Pravaz was a French orthopedic surgeon and inventor of the hypodermic syringe.
Pravaz used his syringe for intra-arterial injection in the treatment of aneurysm. In 1657, experiments were conducted on syringe-like devices by Englishmen Christopher Wren and Robert Boyle, while French physician Dominique Anel created the modern pump syringe as a device to clean wounds using suction.
The use of injections rather than oral drug administration can more readily promote the spread of disease as well as facilitating its cure.
Progress awaited the innovations of Francis Rynd, Charles Pravaz and Alexander Wood.
In 1844, Irish physician Francis Rynd (1811-1861) invented the hollow needle. Wood used his syringe for management of neuralgic pains. Pravaz added a fine, hollow needle to the end of his syringe instead of the tube. Wanting to inject iron perchloridecoagulant into an aneurysm, Pravazadapted Rynd's needle, rather than using the usualsuction tube.

Measuring 3 cm (118 in) long and 5 mm (02 in) in diameter, the syringe was entirely in silver, made by Établissements Charrière, and operated by a screw (rather than the plunger familiar today) to control the amount of substance injected.

In all these cases, it was impossible to performinjectionswithout an incisionuntilIrishphysicianFrancis Rynd invented the hollowneedle in 1844.
But use of syringes relied on either the natural openings of the body or an initial cutting open of the skin. In 1853, French physician Charles Pravaz developed the first practical metal syringe. Yet in the pre-antiseptic era it was a mixed blessing.
