Case ReportsIntrathecal hematoma and arachnoiditis mimicking bacterial meningitis after an epidural blood patch.
We present a case of arachnoiditis and an intrathecal hematoma after an epidural blood patch. A 24-year-old parturient underwent an epidural blood patch three days after an accidental dural puncture during epidural labor analgesia. ⋯ Lumbar magnetic resonance imaging was performed and showed an intrathecal hematoma, with no blood in the epidural space. This report briefly reviews the few cases in the literature of arachnoiditis caused by an intrathecal hematoma and discusses the mechanism which resulted in blood in the subarachnoid space.

Case ReportsEthical and medical management of a pregnant woman with brain stem death resulting in delivery of a healthy child and organ donation.
Maternal brain death during pregnancy remains an exceedingly complex situation that requires not only a well-considered medical management plan, but also careful decision-making in a legally and ethically delicate situation. Management of brain dead pregnant patients needs to adhere to special strategies that support the mother in a way that she can deliver a viable and healthy child. Brain death in pregnant women is very rare, with only a few published cases. ⋯ The patient received continuous hormone substitution therapy, fetal monitoring and extrinsic regulation of maternal homeostasis over 64days. After delivery, the final diagnosis of brain death was established through multi-slice computerized tomography pan-angiography. This challenging case discusses ethical and medical circumstances arising from a diagnosis of maternal brain death, while showing that prolongation of somatic life support in a multidisciplinary setting can result in a successful pregnancy outcome.

Review Meta AnalysisIntrathecal clonidine as an adjuvant for neuraxial anaesthesia during caesarean delivery: a systematic review and meta-analysis of randomised trials.
Clonidine is used as adjuvant to local anaesthetics for spinal anaesthesia. Its potential harm and benefits have not been systematically reviewed in obstetrics, and medical regulatory authorities do not recommend its intrathecal administration. The aim of this study was to assess the safety and efficacy of intrathecal clonidine for caesarean delivery. ⋯ Clonidine is an effective and safe adjuvant to local anaesthetics for spinal anaesthesia for caesarean delivery. This opens the debate as to whether intrathecal clonidine as an "off label" prescription should be reconsidered by medical regulatory authorities.

Each calendar year the Society for Obstetric Anesthesia and Perinatology invites an individual to conduct a review of the medical literature, identifying clinically relevant publications of interest to the obstetric anesthesia provider. This report of that effort covers the publications from 2015 and includes the categories of anesthesia and analgesia, complications of neuraxial procedures, and the effects of anesthesia on the fetus. Neuraxial procedures represent the foundation of obstetric anesthesia; advances in anesthesia and analgesia include novel modes of administration, and refinements in care of the medically complex patient. ⋯ Finally, there are potential effects of anesthesia on the fetal/neonatal brain, much of which remains poorly defined. An analysis of recent papers suggests that epidural fever is not an independent cause of adverse neurologic fetal injury. On the other hand, evidence continues to grow to support the hypothesis that anesthetic drugs impact neonatal neurologic outcome.

Observational StudyIntravenous dexmedetomidine for cesarean delivery and its concentration in colostrum.
Dexmedetomidine is a sedative agent with high α2-adrenoreceptor selectivity. We investigated intravenous dexmedetomidine administration during scheduled cesarean delivery under neuraxial anesthesia; and its concentration in the colostrum. ⋯ The dexmedetomidine milk-to-plasma ratio did not exceed 1 in any participant, and the relative infant dose was very low. Maternal sedation using dexmedetomidine is unlikely to be harmful for the infant.
