Hemodynamic Effects of Xenon Anesthesia in Children

Introduction. In the present trial, the authors studied anti-stress properties of subnarcotic concentrations of gas Xenon (Xe) which is used for treating children with severe traumas. Purpose. To study anti-stress properties of subnarcotic concentrations of gas Xenon (Xe) which is used for treating children with severe injuries. Material and methods. 10 children, aged 13 ± 3 years, with severe trauma were taken into the study: 6 girls with mine-explosive injuries ( a terrorist attack in Kerch in 2018), 3 boys with multiple dog bites and one patient after a traffic accident. To treat them, 20-30% Xe with O2 was used. A session lasted for 20 minutes; the course included from 5 to 12 sessions. Device KTK-01 (LLC “KseMed”, Russia) was used. Pain intensity was assessed with the numerical rating scale (NRS) , sedative effect - with BIS index and Ramsey sedation scale. Patients’ blood was also examined for the level of somatotropic hormone (STH), cortisol (Co) and insulin. Results. Indications for Xe therapy in children were: persistent pain syndrome (PS) and acute stress disorder (ASD). Patients fell asleep (drug-induced sleep) under 20-30% Xe concentration in the respiratory mixture. The average values of BIS index decreased from 95.5 ± 2.5 U to 86.5 ± 5.0 U (p <0.05), and of Ramsay scale - from 5.5 ± 0.5 to 2.7 ± 1.2 points (p <0.05). Pain intensity by NRS decreased from 4.1 ± 1.8 to 1.1 ± 0.4 points (p <0.05). The level of stress hormones during Xe session went down: STH- from 4.8 ± 0.9 ng / ml to 1.9 ± 0.5 ng / ml (p <0.001); Ko - from 375.5 ± 23.6 nmol / L to 303.2 ± 20.7 nmol / L (p <0.0001); insulin - from 19.9 ± 3.6 pmol / L to 11.7 ± 2.7 pmol / L (p <0.001). To restore sleep, 2 - 3 sessions were needed; to relief PS - 5 sessions, to refuse of painkillers in phantom pains - 12 sessions. Conclusion. 20-30% Xe with oxygen therapy has a pronounced analgesic, sedative and anti-stress effect in children with severe injuries.

Introduction. The authors present their experience in experimental and clinical studies on the application of Xenon (Xe) in subnarcotic concentrations for pain relief and for the treatment of acute stress disorders. Preparing wounds for plastic closure in children is a long and painful process which requires many anesthesia procedures during dressings. It leads to cognitive disorders, affects memory and learning potentials. Every third child who survived a severe trauma suffers of acute stress disorders: bad sleep, emotional imbalance, anxiety, asociality, inappropriate actions. Xenon is a non-toxic anesthetic. In the concentration of 20–50%, it is not only anesthetizes, but also decreases acute stress disorders, has sedative and anti-stress effects and normalizes sleep.Objectives. To study literature data on the potentials of gas Xe in subnarcotic concentrations for pain relief and for decreasing acute stress disorders at the stage of preparing a child for plastic closure of a wound defect.Material and methods. Literature search was done in PubMed, Scopus, eLIBRARY, Cyberleninka in English and Russian using key words: “Xenon”, “Xenon and anesthesia”, “Xenontherapy” “Actions of Xenon”, “Treatment of extensive wounds in children”, “Acute stress disorders”.Results. The analysis of the data of the conducted studies showed the non-toxicity of Xe, which makes it possible to use it repeatedly for anesthesia in children. The fact that Xe reduces the manifestations of anxiety, depressive and psychosomatic symptoms in patients with acute and chronic stress disorders allows us to count on its positive effects in the treatment of children with extensive wounds of traumatic origin at the stage of preparing them for plastic closure.Conclusion. The practical absence in the available scientific literature of a study to assess the effectiveness of the use of subnarcotic concentrations of Xe, when dressing extensive wounds at the stage of preparation of the wound process for plastic closure in children with acute stress disorders, justifies the conduct of an appropriate scientific study.
