When diagnosed antenatally placenta accreta has often been managed by cesarean hysterectomy, but recently techniques involving uterine preservation have been developed. Uterine artery embolization has become an adjuvant treatment, although the potential for obstetric hemorrhage still exists. A multidisciplinary approach has permitted the development of anesthetic strategies for these patients. ⋯ In this case series, the expectation of major blood loss at cesarean delivery in the presence of placenta accreta and attempts at uterine conservation surgery initially prompted a conservative approach using general anesthesia. Greater experience has permitted modification of this approach and neuraxial anesthesia is now employed more frequently. When managed appropriately, most patients are able to tolerate both prolonged surgery and significant blood loss under epidural anesthesia.

Assessment of coagulation in the obstetric population using ROTEM® thromboelastometry.
Assessment of maternal coagulation to determine suitability for neuraxial anaesthesia and management of obstetric haemorrhage remains a challenge. Thromboelastography provides point of care patient assessment of the viscoelastic properties of whole blood clotting and can assist the clinician in haemostatic decision-making. The study aim was to determine the ROTEM® thromboelastometer 95% reference limits for third trimester parturients and to compare these with non-pregnant female controls. ⋯ ROTEM® thromboelastometry clearly demonstrates the hypercoagulability of pregnancy. Formal reference ranges for ROTEM® that may be potentially useful in the haemostatic management of the parturient are presented.

Care of pregnant migrants is a considerable challenge for all health care workers and health systems. Maternal mortality and serious morbidity are both greatly increased among migrants in western countries, particularly in Africans and asylum seekers. While in many instances, migrants are healthier than native populations and have better perinatal outcomes, this is inconsistent and poorer outcomes are described in many groups. ⋯ Accordingly, improvement in outcome requires a multifaceted approach with a focus on early access to antenatal services and enhanced medical screening and surveillance for detection and optimisation of comorbid conditions. Provision and/or acceptance of analgesia in labour have not been well researched but existing data are sufficient to suggest that some migrant groups do not receive equivalent pain relief during labour. Provision of information and translation services are important components in improvement of standards of care.
