The use of neuroaxial blockades in obstetric practice for thrombocytopenia

Thrombocytopenia is the second most frequent hematological complication of pregnancy after anemia. Among all thrombocytopenia during pregnancy, the most common is gestational thrombocytopenia. Gestational thrombocytopenia is not accompanied by coagulation disorders, has a minimal risk of bleeding, for both a mother and her fetus. Nevertheless, according to modern concepts, thrombocytopenia is a contraindication for performing obstetric neuroaxial blockades only on the basis of quantitative count of platelets, without taking into account coagulation status. These contraindications are derived from the general surgery and traumatology practice due to the high risk of developing epidural hematoma, but do not take into account the features, including physiological hypercoagulation, of pregnant patients. Refusal of the patient to perform a neuroaxial blockade during delivery on the basis of only counting the number of platelets often leads to an unreasonable increase in the risk / benefit ratio for both the mother and the fetus. Analysis of the research results indicates a change in attitude towards this problem towards a more loyal approach, taking into account the assessment of the coagulative status of a particular patient

SAFETY OF NEUROAXIAL BLOCKADES AT SURGICAL DELIVERY IN PATIENTS WITH DISSEMINATED SCLEROSIS

We realized, prospective study, including staging clinicolaboratory and specialized neurological research during 12 months after the operation, to estimate the course of disseminated, sclerosis after Cesarean section at the neuroaxial blockades with use of modern local anesthetics. We observed 17 patients of 26—30 years with disseminated, sclerosis. It is showed, that neuroaxial anesthesia techniques with modern local anesthetics at the operative delivery don't worsen the prognosis of underlying disease

Blood saving possibilities in delivering patients with placenta increta

According to the results of systematic reviews of WHO, maternal mortality associated with massive bleeding almost reached 30% and has no tendency to decrease. Among the causes of massive obstetric hemorrhage, the most challenging ones are uterine hypotension and morbidity adherence placenta. Most severe complication for placentation is placenta increta in the uterine wall. Over the past 50 years, the number of cases with morbidity adherence placenta has increased tenfold. By all indications, this pathology has taken on the character of an epidemic and is one of the main causes for massive blood loss and blood transfusion, as well as peripartum hysterectomy. For surgical hemostasis in this pathology we apply X-ray vascular methods (temporary balloon occlusion of large vessels, vascular embolization), ligation of the iliac, uterine, ovarian arteries, various versions of distal hemostasis, including the use of uterine turnstiles, intrauterine and vaginal cylinders, compression sutures. However, data confirming the advantage of any specified methods are not enough. The risk of massive bleeding is high while using any of these methods. The article analyzes the blood saving methods existing at the present stage and possibility of these methods usage in obstetrics. Besides, we describe efficacy and safety of their use in massive blood loss, including the surgical treatment of morbidity adherence placenta

Возможности тромбоэластографии при оценке безопасности нейроаксиальных блокад при гестационной тромбоцитопении (клиническое исследование)

Gestational thrombocytopenia (GT) is the most common type of thrombocytopenia during pregnancy. Unlike other types of thrombocytopenia, it is not accompanied by dysfunction of the cellular component of hemostasis. Currently, a quantitative decrease in platelets in GT is a contraindication to neuraxial blockades (NAB), which significantly reduces the quality of care in childbirth.The aim of the study is to determine the possibility of safe use of neuraxial blockades in gestational thrombocytopenia. A retrospective prospective study involved 70 patients who were performed delivery, depending on obstetric indications, either conservatively or surgically. The patients were divided into two groups. The main group (group No. 1) included 35 patients with gestational thrombocytopenia. The comparison group (group No. 2) consisted of 35 patients with a platelet content above 150×109/l. A comparative intergroup analysis of indicators of a general blood test, coagulogram, thromboelastography with a test for functional fibrinogen before childbirth and 2 days after delivery. The change in platelet content and its effect on the coagulation status of patients during pregnancy were retrospectively analyzed. A comparative assessment of the volume of blood loss during childbirth and the early postpartum period and the risk of complications of neuraxial blockade in patients with and without gestational thrombocytopenia was carried out.It was found that during gestational thrombocytopenia in the perinatal period, there is no decrease in coagulation potential, assessed by the results of coagulography and thromboelastography at a platelet level above 49×109/l. The investigated indicators of hemostasis did not have significant intergroup differences during pregnancy and childbirth. In the group of patients with gestational thrombocytopenia, the volume of blood loss during labor and the postpartum period did not differ from the group without thrombocytopenia, regardless of the method of delivery. The median blood loss after vaginal delivery in group 1 was 225 ml, in group 2 – 250 ml, with abdominal delivery – 572 ml and 386 ml – respectively. In this study, no complications of neuraxial blockade were observed in any of the groups.The results obtained suggest that in patients with gestational thrombocytopenia, even with a significant decrease in platelet content, it is possible to perform neuraxial blockades during labor, taking into account the clinical picture and the absence of coagulation disorders confirmed by thromboelastography.ВВЕДЕНИЕ Гестационная тромбоцитопения (ГТ) является наиболее распространенным видом тромбоцитопении во время беременности. В отличие от других видов тромбоцитопении она не сопровождается нарушением функции клеточного звена гемостаза. В настоящее время количественное снижение тромбоцитов при ГТ является противопоказанием к проведению нейроаксиальных блокад (НАБ), что значительно снижает качество оказания помощи в родах.ЦЕЛЬ ИССЛЕДОВАНИЯ Определить возможности безопасного применения НАБ при ГТ.МАТЕРИАЛ И МЕТОДЫ В ретроспективно-проспективном исследовании приняли участие 70 пациенток, родоразрешенных в зависимости от акушерских показаний консервативным или оперативным путем. Пациентки были разделены на две группы. В основную группу (группа № 1) вошли 35 пациенток с ГТ. Группу сравнения (группа № 2) составили 35 пациенток с содержанием тромбоцитов в крови выше 150×109/л. Проведен сравнительный межгрупповой анализ показателей общего анализа крови, коагулограммы, тромбоэластографии с выполнением теста на функциональный фибриноген перед родами и через 2 дня после родоразрешения. Ретроспективно проанализированы изменение содержания тромбоцитов и его влияние на коагуляционный статус пациенток в течение беременности. Проведена сравнительная оценка объемов кровопотери в родах и раннем послеродовом периоде и риска развития осложнений НАБ у пациенток с ГТ и без нее. Выявлено, что при ГТ в перинатальном периоде не происходит снижения коагуляционного потенциала, оцениваемого по результатам коагулографии и тромбоэластографии при уровне тромбоцитов выше 49×109/л. Исследованные показатели гемостаза не имели значимых межгрупповых различий в течение беременности и родов. В группе пациенток с ГТ объем кровопотери в родах и послеродовом периоде не отличался от группы без тромбоцитопении независимо от метода родоразрешения. Медиана кровопотери после родов через естественные родовые пути в группе № 1 составила 225 мл, в группе № 2 — 250 мл, при абдоминальном родоразрешении — 572 мл и 386 мл соответственно. В проведенном исследовании не зафиксировано каких-либо осложнений НАБ ни в одной из групп.ЗАКЛЮЧЕНИЕ Полученные результаты позволяют предположить, что у пациенток с ГТ даже при значительном снижении содержания тромбоцитов возможно выполнение НАБ в родах с учетом клинической картины и отсутствия нарушений коагуляции, подтвержденных тромбоэластографией

Выбор анестезиологического пособия при органосохраняющих операциях по поводу врастания плаценты

Abstract Placenta accreta (PAS-disorders) is one of the most serious complications of pregnancy, associated with the risk of massive uterine bleeding, massive hemotransfusion and maternal mortality. Peripartum hysterectomy is a common treatment strategy for patients with placenta accreta. Currently, there is a clear trend of changing surgical tactics in favor of organ-saving operations, but there are no studies devoted to anesthesiological support of such operations.The aim of the study is to substantiate an effective and safe method of anaesthesia in organ-saving operations for placenta accreta spectrum disorders.Materia l and methods The study involved 80 patients with a diagnosis of placenta accreta spectrum disorders, confirmed intraoperatively, who underwent organ-saving operations. The patients were randomized depending on the method of anesthesia into 3 groups: general anesthesia, spinal anesthesia with planned conversion to general after fetal extraction and epidural anesthesia with planned conversion to general also after fetal extraction. The comparison of intraoperative hemodynamics, efficiency of tissue perfusion, efficiency of antinociceptive protection at the stages of surgery was performed. A comparative analysis of the volume of blood loss and blood transfusion, time of patients activation in the postoperative period, severity of pain on the first day after surgery, duration of hospital stay before discharge and comparison of the assessment of the newborn according to Apgar score at first and fifth minute after extraction.Conclusion The study shows that the optimal method of anesthesia in organ-saving operations for placenta accreta spectrum disorders is epidural anesthesia with its planned conversion to general anesthesia with an artificial lung ventilation after fetal extraction. Such an approach to anesthesia allows to maintain stable hemodynamic profile with minimal vasopressor support, sufficient heart performance, providing effective tissue perfusion and a high level of antinociceptive protection at the intraoperative stage and reduce the volume of intraoperative blood loss and hemotransfusion. In the current study there were no differences in neonatal outcomes and duration of hospitalization depending on the method of anesthesia. The advantage of epidural anesthesia with its conversion to general anesthesia was earlier activation after surgery and lower intensity of postoperative pain syndrome.Резюме Врастание плаценты (placenta accreta, PAS-disorders) - одно из наиболее серьезных осложнений беременности, сопряженное с риском массивного маточного кровотечения, массивной гемотрансфузии и материнской смертности. Общепринятой стратегией лечения пациенток с врастанием плаценты является перипартальная гистерэктомия. В настоящее время отмечается отчетливая тенденция изменения хирургической тактики в пользу органосохраняющих операций, но исследований, посвященных анестезиологическому обеспечению таких операций, нет.Цель исследования Обоснование эффективного и безопасного способа анестезиологического пособия при органосохраняющих операциях по поводу врастания плаценты.Материал и методы В исследовании приняли участие 80 пациенток с диагнозом врастания плаценты, который был подтвержден интраоперационно. Всем пациенткам выполнены органосохраняющие операции. В зависимости от способа анестезиологического пособия были сформированы три группы: общей анестезии, субарахноидальной анестезии с плановой конверсией в общую после извлечения плода и эпидуральной анестезии с плановым переходом в общую также после извлечения плода. Выполнено сравнение интраоперационной гемодинамики, показателей эффективности тканевой перфузии, эффективности антиноцицептивной защиты на этапах операции. Проведен сравнительный анализ объемов кровопотери и гемотрансфузии, времени активизации пациенток в послеоперационном периоде, оценки выраженности болевого синдрома в 1-е сутки после операции, длительности пребывания в стационаре до выписки и сравнение оценки новорожденных по шкале Апгар на 1-й и 5-й минутах после извлечения.Зак лючение В исследовании показано, что оптимальным способом анестезиологического пособия при органосохраняющих операциях по поводу врастания плаценты является эпидуральная анестезия с ее плановой конверсией в общую анестезию с искусственной вентиляцией легких после извлечения плода. Подобный подход к анестезии позволяет поддерживать стабильность гемодинамического профиля и минимизировать вазопрессорную поддержку, сохранить достаточную производительность сердца и перфузию тканей. Антиноцицептивный эффект сочетания эпидуральной и общей анестезии был выше как на интраоперационном этапе, так и в послеоперационном периоде. Преимуществом эпидуральной анестезии с ее переходом в общую явилось снижение объемов интраоперационной кровопотери и гемотрансфузии. В проведенном исследовании не выявлено различий в неонатальных исходах и сроках госпитализации в стационаре в зависимости от способа анестезиологического пособия
