Влияние метилпреднизолона на эндотелиальную функцию при кардиохирургических операциях в условиях искусственного кровообращения

Влияние метилпреднизолона на эндотелиальную функцию при кардиохирургических операциях в условиях искусственного кровообращения

Abstract

The aim of the study. Evaluate the effect of methylprednisolone on endothelial function in operations under normothermic cardiopulmonary bypass. 22 patients underwent operation without the use of methylprednisolone (control group) and 22 patients with intravenous methylprednisolone injection after induction of anesthesia in a dose of 20 mg/kg (study group). Microalbuminuria and the ratio of albumin to creatinine in urine were selected as markers of capillary leakage identified. Endothelin-1 and E-selectin were selected as markers of endothelial dysfunction. The levels of interleukin-6, interleukin-10, creatinine, albumin, cystatin C, blood glucose, blood gases and perioperative results were evaluated. In the methylprednisolone group the indicators of systemic inflammatory response were less at stages of study. However, there were an increase in markers of endothelial dysfunction and transient impairment of renal function and lung with no significant difference in markers of capillary leakage in this group by comparing with control group. The application of pulse-dose corticosteroids aggravates the effects of endothelial dysfunction (increased levels of endothelin-1 and E-selectin on the stages of the study) and negatively affects the recovery of pulmonary and renal function after cardiopulmonary bypass. The use of methylprednisolone does not reduce the manifestations of capillary leak syndrome.

Цель исследования оценить влияние метилпреднизолона на эндотелиальную функцию при операциях в условиях нормотермического искусственного кровообращения. Обследовано 22 пациента без применения метилпреднизолона (контрольная группа) и 22 пациента с внутривенным введением метилпреднизолона в дозе 20 мг/кг массы тела после индукции анестезии (основная группа). В качестве маркеров капиллярной утечки были определены микроальбуминурия и отношение альбумина к креатинину в моче. Маркерами эндотелиальной дисфункции были выбраны эндотелин-1 и sE-селектин. Оценивались уровни ИЛ-6, ИЛ-10, креатинина, альбумина, цистатина С, глюкозы в сыворотке крови, газовый состав крови. В группе с применением метилпреднизолона при сравнении с контрольной группой на этапах исследования показатели системного воспалительного ответа были меньше, однако отмечалось увеличение уровня маркеров эндотелиальной дисфункции, транзиторное ухудшение показателей функции почек и легких при отсутствии значимого различия маркеров капиллярной утечки. Установлено, что применение пульс-дозы глюкокортикостероидов усугубляло явления эндотелиальной дисфункции (увеличение уровней эндотелина-1 и sE-селектина на этапах исследования) и отрицательно влияло на восстановление легочной и почечной функций после искусственного кровообращения. Выявлено, что использование метилпреднизолона не уменьшает проявлений синдрома капиллярной утечки.
