“…It was then decided to add gaseous nitric oxide to the ECMO circuit (Figure 1). To generate nitric oxide, we used a device (Tianox; RFNC-VNIIEF, Russia) that produced nitric oxide from the ambient air, supplied it into the extracorporeal circuit, and monitoring/regulating NO concentration in the supplying mixture [4,5]. The average dosage of nitric oxide was 40 ppm; the average NO 2 concentration was 0.2-1.1 (0.80±0.06) ppm.…”

The aim of the study was to test the use of gaseous nitric oxide added to the extracorporeal membrane oxygenation (ECMO) system for treating critical acute heart failure after cardiac surgery.Materials and Methods. Venoarterial ECMO with addition of nitric oxide into the extracorporeal circuit was used for treating a 52-yearold patient after two-step cardiac surgery for acute dissection of the thoracic aorta and aortic valve insufficiency. After the Bentall-de Bono procedure, a technical error was revealed: that was a non-functioning anastomosis to the right coronary artery, which caused massive ischemic myocardial injury. An emergency myocardial revascularization was performed with the help of the cardiopulmonary bypass converted into ECMO; the patient's condition improved and he was transferred to the ICU.Results. Considering the sharp decrease in heart contractility and the extremely high level of myocardial damage markers, it was decided to supply nitric oxide (40 ppm) to the ECMO circuit. A positive effect was noted within 8 h from the start of the procedure: the concentration of creatine phosphokinase-MB decreased almost 4 times and the concentration of troponin I decreased twofold. The most pronounced changes were observed by the end of day 1: a significant decrease in the concentration of myocardial damage markers, a decrease in the VIS indicator by 7.5 times; an improvement in the contractile function. Further on, the patient's condition gradually stabilized: the manifestations of acute heart failure and multiple organ failure stopped, and then ECMO was discontinued after 82 h of work. The patient was decannulated and he continued to show stable hemodynamic parameters. He was discharged from the clinic on day 18 after surgery. Conclusion.For the first time, venoarterial ECMO with supply of gaseous nitric oxide into the extracorporeal circuit was used to support blood circulation after cardiac surgery. This made it possible to ensure the survival of the patient with critical ischemia-reperfusion injury developed after the surgery.

“…It was reported that a high-voltage diffuse discharge at a low gas pressure and a low power could be used for the inactivation of microbiological cultures [2]. As is known [3], a volume discharge can be generated using inhomogeneous electric field in gases at atmospheric pressure.…”

-We have studied the modification of the near-surface layers of a copper foil under the action of a volume gas discharge, which was generated in air at atmospheric pressure by nanosecond highvoltage pulses of both negative and positive polarity applied between the foil and an electrode with a small radius of curvature. It is established that the surface layer of the discharge-treated copper foil in the central region is cleaned from carbon contaminations, while oxygen atoms penetrate in depth of the foil. The depth of a cleaned layer depends on the polarity of voltage pulses. For the positive voltage polarity on the foil, the cleaning takes place up to a depth exceeding 50 nm, while oxygen penetrates up to a depth of about 25 nm.
