[Epidural analgesia in obstetrics: is there an effect on labor and delivery?].
Epidural analgesia is routinely used in obstetrics but has been blamed for possible effects on labor that lead to greater use of instruments or conversion to cesarean delivery. We aimed to assess this possibility in a cohort of obstetric patients receiving or not receiving epidural analgesia. ⋯ Although epidural analgesia has traditionally been associated with a higher incidence of difficult labor and delivery, this association was not unequivocally evident in this cohort of patients. The apparent increase seems to be attributable to such obstetric factors as longer duration of stages of labor, higher body mass index, and first delivery.

Practice Guideline[Neuroanesthesia for embolization of a ruptured cerebral aneurysm: clinical practice guidelines].
When the neuroanesthesia working group of the Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor surveyed Spanish anesthesiologists to learn the degree of their involvement in the diagnosis and treatment of spontaneous subarachnoid hemorrhage, a surprising finding was that anesthetists did not participate in endovascular repair of intracranial aneurysms when the procedure was carried out in an interventional radiology department. These interventions, which are considered minimally invasive and are performed outside the operating room, are not risk-free. Based on the survey results and a systematic review of the literature, the working group has provided practice guidelines for the perioperative management of anesthesia for endovascular repair of ruptured cerebral aneurysms. In our opinion, the diversity of practice in the hospitals surveyed calls for the application of practice guidelines based on consensus if we are to reduce variability in clinical and anesthetic approaches as well as lower the rates of morbidity and mortality and shorten the hospital stay of patients undergoing exclusion of an aneurysm.

[Transcranial Doppler ultrasound, bispectral index, and electroencephalographic monitoring of entropy during sevoflurane anesthesia in children].
Transcranial Doppler ultrasound is a noninvasive technique for monitoring the velocity of blood flow in the main intracranial arteries, particularly those in the circle of Willis. Our aim was to assess whether changes in cerebral arterial blood flow in pediatric patients under sevoflurane anesthesia demonstrated by pulsed Doppler ultrasound correlate with changes in the bispectral (BIS) index and electroencephalographic state and response entropy (ES and ER, respectively). ⋯ We show Doppler ultrasound patterns during anesthetic induction with sevoflurane. Systems for monitoring hypnosis could be considered indirect measurements of cerebral blood flow; BIS measurements are more sensitive to change. Transcranial Doppler ultrasound facilitates the observation of changes in blood flow that occur at different levels of hypnosis during anesthesia.
