New recommendations for thromboelastography reference ranges for pregnant women

Impact de l’âge maternel avancé sur les profils de coagulation thrombo-élastographique du péripatum: une étude observationnelle prospective exploratoire

“…Compared with non-pregnant controls, data from these thromboelastographic studies indicate that pregnant women have shorter r times, 8,[28][29][30] shorter k times, 8,28,30 longer MA and a angles, 8,28,30 and greater coagulation index values. 28,30 Similar findings were observed in a longitudinal study reporting TEG variables during and after pregnancy. 9 Compared with TEG variables eight weeks postpartum, the mean reductions in r time and k time during pregnancy varied from 23-26% to 18-35%, respectively, and the mean increases in MA and a angle during pregnancy varied from 12-20% to 6-8%, respectively.…”

“…The median [IQR] ages of women were 38 [37][38][39][40][41] yr and 29 [25][26][27][28][29][30][31][32][33][34] yr in the AMA and non-AMA groups, respectively (Table 1). Other maternal demographic and obstetric characteristics were similar in both groups (Table 1).…”

“…Nous avons utilisé un modèle de régression linéaire d'effets mélangés (SAS Ò PROC MIXED) pour évaluer les différences entre les groupes concernant les résultats individuels des paramètres thrombo-élastographiques et de coagulation. Résultats Les âges médians (intervalle interquartile) des femmes étaient de 38 (37-41) ans et 29 (25)(26)(27)(28)(29)(30)(31)(32)(33)(34) ans pour, respectivement, les groupes AMA et non AMA (P \ 0,001). Nous n'avons observé aucun effet statistiquement significatif de groupe d'étude sur les paramètres thrombo-élastographiques ou sur les paramètres de laboratoire de la coagulation.…”

“…The aim of this prospective observational study was to compare peripartum thromboelastography parameters of AMA and non-AMA women undergoing elective Cesarean delivery (CD). [25][26][27][28][29][30][31][32][33][34] yr in the AMA and non-AMA groups, respectively (P \ 0.001). We observed no statistically significant effect of study group on any thromboelastographic or laboratory coagulation parameters.…”

Integrated assessment haemostasis pregnant women with gestosis

“…При постоянной температуре 37 °C, чашечка совершала медленные колебания, когда в кювете формировался сгусток, стержень начинал вращаться вместе со сгустком. Профиль коагуляции оценивали по пяти основным ТЭГ-параметрам [6,12,14]: R -время реакции от начала теста; K -время свертывания крови; угол α -скорость увеличение плотности сгуст-ка; MA -максимальная амплитуда, плотность сгустка; LI30 -процент 30-минутного лизиса сгустка.…”
