Dexmedetomidine Pretreatment Protects Against Myocardial Ischemia/Reperfusion Injury by Activating STAT3 Signaling.
Myocardial infarction is a common perioperative complication, and blood flow restoration causes ischemia/reperfusion injury (IRI). Dexmedetomidine (DEX) pretreatment can protect against cardiac IRI, but the mechanism is still insufficiently understood. ⋯ DEX pretreatment protects against myocardial IRI, presumably by promoting STAT3 phosphorylation via the α2-adrenoreceptor in vivo and in vitro.

Relying on original, primary source documentation from the National Archives, we describe the practice of anesthesia in mobile army surgical hospital (MASH) units and the 171st Evacuation Hospital during the latter part of the Korean War in 1953. Values were scaled and reported as percentages. These Essential Technical Medical Data Sheets reveal a surprising proportion (12.9%) of men received spinal anesthetics, despite official recommendations to the contrary. ⋯ Utilizing primary source documentation, we found that general anesthesia was the most common type utilized. Newer techniques were not as commonly adopted, despite official recommendations and data from the time. The care provided closely resembled that delivered in the Second World War but inspired a series of technological and pedagogical reforms through the 1950s to improve military anesthesia for the next conflict.
