Achille Mario Dogliotti was a surgeon–scientist whose work bridged anesthesia, analgesia, general and cardiac surgery, with a focus on integrating neuraxial anesthesia into operative care. He developed segmental epidural (peridural) anesthesia in the early 1930s, injecting local anesthetic into the epidural space to produce targeted, segmental blockade while avoiding many spinal anesthesia risks.
He described the loss-of-resistance technique to identify the epidural space and emphasized a tactile sign of correct needle placement, arguing that epidural anesthesia acts extradurally on spinal nerves and dorsal roots with minimal cerebrospinal fluid spread. This work helped convert epidural anesthesia from experimental to standardized practice.
Dogliotti also contributed to pain therapy by pioneering chemical neurolysis, including alcoholisation of posterior nerve roots, cranial ganglia, and peripheral nerves for refractory neuralgia. In the late 1940s, he led a cardiothoracic program in Turin and, on August 7, 1951, reported a successful short-term extracorporeal circulation-assisted operation during thoracic tumor resection, illustrating partial, time-limited extracorporeal circulation as a lifesaving measure in acute surgical crises.
He promoted a broader, modernized view of epidural anesthesia and integrated surgical physiology with clinical innovation.
A Comprehensive Synthesis of Dogliotti’s Contributions to Anesthesia, Pain Therapy, and Cardiothoracic Surgery
This technique was positioned as an intermediate modality between spinal anesthesia (Corning–Bier method) and paravertebral approaches, enabling anesthesia of a series of spinal nerves without intrathecal entry.
His conceptual framework framed epidural anesthesia as a reproducible, anatomically grounded procedure.
By maintaining constant syringe plunger pressure during advancement, the operator could detect a sharp drop in resistance signaling correct placement.
He phrased this as a tactile cue indicating entry into the peridural space, with the anesthetic entering readily thereafter.
This evidence-bearing approach contributed to moving epidural anesthesia from experimental novelty toward standard clinical practice.
He employed alcoholization of posterior nerve roots and cranial nerve ganglia, applying these methods to patients with refractory neuralgia.
This position in pain management reflected a neuromodulatory philosophy consistent with surgical and neuroanatomical rationales.
His environment fostered approaches to acute cardiopulmonary failure that blended research and operative practice.
This framing emphasized supportive rather than definitive replacement mechanisms during crisis.
The case involved a 57-year-old man undergoing thoracotomy for a large mediastinal tumor compressing the great veins and right heart.
Circulatory support lasted about 20 minutes, during which the patient stabilized sufficiently to complete tumor resection.
Postoperative recovery was notable for absence of biochemical or renal evidence of blood trauma, and arterial pressure rose promptly upon initiating artificial circulation.
He introduced the term “circolazione assistita” (assisted circulation) and proposed potential future applications in conditions such as pulmonary embolism, acute pulmonary edema, asphyxia, and acute cardiac failure.
It does not report broader comparative effectiveness, long-term follow-up, or systematic safety data for epidural techniques as used in various contexts.
There is also limited discussion of patient selection criteria, perioperative management protocols, and comparative frameworks relative to contemporaneous modalities.
