Observational StudyUtility of viscoelastography with TEG 6s to direct management of haemostasis during obstetric haemorrhage: a prospective observational study.
The TEG 6s is an automated cartridge-based device with limited description of use in obstetric haemorrhage. The aim of this analysis was to describe the utility of TEG 6s in identifying abnormal laboratory results of coagulation and platelet count, and inform an interventional treatment algorithm for postpartum haemorrhage. ⋯ The TEG 6s CFF can be used to identify low fibrinogen during obstetric haemorrhage. A value to identify transfusion thresholds for PT/aPTT and platelets was not established, and laboratory results should continue to be used.

Factor XIII activity at onset of labour and association with postpartum haemorrhage: an exploratory post-hoc study.
Platelets, fibrinogen and factor XIII (FXIII) are required to form a stable clot in case of haemorrhage. The aims of this study were to evaluate a possible association between FXIII activity at the onset of labour and postpartum haemorrhage (PPH), and to ascertain whether FXIII activity at labour onset differs from after delivery. ⋯ At the onset of labour women with a subsequent PPH had significantly lower mean FXIII activity than that of women without PPH. This difference was small and within normal limits. FXIII activity did not change during normal delivery. The importance of FXIII during PPH requires study.

Case ReportsFetal heart rate mirrors maternal temperature during posterior fossa craniotomy: a case report.
While it is well known that maternal temperature affects fetal heart rate, the exact relationship is not well described. The circumstances accompanying most cases of maternal hypothermia and rewarming (e.g. a drowning event) have precluded a precise quantitative description of this relationship. ⋯ Continuous electronic fetal heart rate and core temperature monitoring demonstrated a near linear relationship during the development of hypothermia and rewarming. Recognition of the close relationship between maternal temperature and fetal heart rate can help safeguard maternal and fetal health, and prevent unnecessary delivery during non-obstetric surgery in pregnancy.
