Case Reports[Epidural anesthesia in obstetrics: an accidentally placed intrathecal catheter--remove it or use it?].
Epidural anesthesia is an established method in obstetrics. Despite constant practical experiences and established techniques, accidental penetrations of the dura and therefore malpositioning of the catheter in the intrathecal space are still present. This can result in post spinal headaches, a higher dispersion of the local anesthetic followed by life-threatening respiratory insufficiency and loss of overall conscious delivery. ⋯ There was no change in tonicity. It resulted in a normal unproblematic vaginal birth. After an initial irritation due to the high dispersion the patient described a noticeable alleviation of pain during the adequate controlled labor.

Review[Thromboprophylaxis during pregnancy and the puerperium: highlights from current guidelines].
Venous thromboembolism (VTE) is one of the leading causes of maternal deaths worldwide. Mortality and morbidity of VTE are potentially preventable, since two-thirds of these women have identifiable risk factors and may benefit from appropriate thromboprophylaxis. Individual and careful assessment of the personal and family history as well as the assessment of pre-existing and new-onset/transient risk factors during pregnancy and after delivery are mandatory for an effective prevention of VTE. ⋯ At the onset of labour, in case of any vaginal bleeding, prior to induction of labour or 12 h before an elective Caesarean section, antenatal LMWH prophylaxis should be discontinued, LMWH prophylaxis can be continued for 4-6 h after vaginal and for 6-12 h after Caesarean delivery when the women do not have an increased risk of haemorrhage. Current guidelines recommend than LMWH are the agents of choice for antenatal thromboprophylaxis; in comparison to unfractionated heparin, LMWH are associated with a substantially lower risk of heparin-induced thrombocytopenia and osteoporosis. Both oral anticoagulants and heparin are safe when breast-feeding.
