Dogliotti's principle: In epidural anaesthesia, the principle that the change of pressure from the ligamentum flavum to the epidural space can be identified by constant pressure on the piston of a syringe whilst advancing a needle into the patient's back, thus permitting identification of the epidural space^[1].

The technique was described by Professor A. Mario Dogliotti in 1933^[2], an Italian physician from the Institute of Surgical Pathology in Turin, Italy. This technique remains in use at present^[update], and is commonly referred to the loss of resistance to saline technique or its variation the loss of resistance to air technique.
