Recent literature on the role of transthoracic echocardiography in the management of women with preeclampsia is reviewed with emphasis on recommendations for its use in the life-threatening complications of acute pulmonary edema, chest pain, and hemorrhage. ⋯ The role of transthoracic echocardiography in the management of women with preeclampsia is emphasized by international groups. Research into the hemodynamics in preeclampsia, which demonstrates preserved ejection fraction, and diastolic dysfunction highlights its utility and acceptability by pregnant women with preeclampsia. Training of obstetric anesthesiologists in echocardiography is necessary to enable more widespread implementation of this important technology.

The aim of this review is to discuss recent developments in vascular access technology and to highlight those that are particularly relevant to the practitioner. ⋯ Despite the development of new technical devices, successful venous puncture remains heavily dependent on the skills of the operator.

ReviewPatient-controlled intravenous analgesia remifentanil for labor analgesia: time to stop, think and reconsider.
Remifentanil is a relatively new but commonly used opioid alternative in the management of labor pain relief. The present article evaluates efficacy and safety of patient-controlled intravenous analgesia (PCIA) with remifentanil in the management of labor pain relief. ⋯ Remifentanil PCIA is a valuable analgesic strategy whenever regional analgesia is contraindicated. Using it as first line strategy seems to be contraindicated because of significant respiratory side-effects to the mother. Whenever used advanced and continuous monitoring using capnography, saturation monitoring and one-to-one midwifery care are mandatory!

The term 'safe use of anesthesia in children is ill-defined and requires definition of and focus on the 'safe conduct of pediatric anesthesia'. ⋯ This initiative addresses the well known perioperative risks in young children, perioperative causes for cerebral morbidity as well as gaps in regulations, teaching and research. Defining the 'who', 'where', 'when' and 'how' in this context provides the framework for the safe conduct of pediatric anesthesia.

ReviewThe role of cardiac output monitoring in obstetric anesthesia.
Haemodynamic monitoring in obstetric patients has evolved during the last decade, with the development of minimally invasive and noninvasive continuous cardiac output (CO) monitors. This review focuses on recent articles that improve our understanding of physiology and haemodynamic changes during spinal anaesthesia in healthy pregnant women, and pathophysiology in women with preeclampsia and other cardiovascular disease. ⋯ In healthy women, left lateral tilt remains an important clinical intervention during caesarean delivery, and phenylephrine is an essential early adjunct to fluid therapy. Noradrenaline may have a clinical benefit in selected patients. Carbetocin has similar haemodynamic effects to oxytocin. Haemodynamic changes associated with delivery per se may be minor compared with those due to oxytocin. Uncomplicated severe preeclampsia is usually associated with a normal to raised CO. Early-onset preeclampsia may be associated with more vasoconstriction and lower CO than late-onset disease. Passive leg raising may be useful to judge fluid responsiveness, and lung ultrasound may predict pulmonary oedema in preeclampsia. Further research is warranted to study the area of circulatory changes during delivery and the postpartum period, in healthy and preeclamptic women.
