Retrospective controlled cohort. ⋯ In postoperative PSF for patients with AIS receiving LB through ESPB, those who did not receive a PCA had lower opioid consumption without worse pain scores or mobility and had a lower LOS. Adding LB through ESPB to postoperative pain regimens effectively replaces a PCA by providing the same pain control and reducing overall opioid consumption and LOS.

The traditional management of pregnant patients with Chiari I malformation (CM-I) heavily favors cesarean section and general anesthesia to limit the perceived risk of maternal neurological complications attributed to vaginal delivery and neuraxial anesthesia. The aim of this study was to compare reported neurological symptoms and radiographic presentations before and after childbirth performed by patients with CM-I, with and without associated syrinx. ⋯ Our findings suggest that patients with CM-I may deliver vaginally and receive neuraxial anesthesia with low risk of neurological complications or radiographic worsening. As these patients were not prospectively selected, limitations exist, and it remains important to consider the severity of the patient's clinical and radiographic presentation when selecting anesthetic and delivery modality.

Gut Microbiota Influences Developmental Anesthetic Neurotoxicity in Neonatal Rats.
Anesthetic exposure during childhood is significantly associated with impairment of neurodevelopmental outcomes; however, the causal relationship and detailed mechanism of developmental anesthetic neurotoxicity remain unclear. Gut microbiota produces various metabolites and influences the brain function and development of the host. This relationship is referred to as the gut-brain axis. Gut microbiota may influence developmental anesthetic neurotoxicity caused by sevoflurane exposure. This study investigated the effect of changes in the composition of gut microbiota after fecal microbiota transplantation on spatial learning disability caused by developmental anesthetic neurotoxicity in neonatal rats. ⋯ The alternation of gut microbiota after fecal microbiota transplantation influenced spatial learning ability in neonatal rats with developmental anesthetic neurotoxicity. Modulation of the gut microbiota may be an effective prophylaxis for developmental anesthetic neurotoxicity in children.

ReviewPerioperative management of patients with mediastinal mass syndrome.
The mediastinal mass syndrome (MMS) can occur after induction of anesthesia, intraoperatively or even days after the surgical procedure. The focus of this review is on the management of pediatric and adult patients with a significant mediastinal mass. ⋯ Meticulous planning, implementation of anesthetic management protocols and protocols for emergency situations are essential to guarantee patient safety with a mediastinal mass.

Randomized Controlled TrialRandomized Double-Blind Study of the Effect of Injectate Temperature on Intrathecal Bupivacaine Dose Requirement in Spinal Anesthesia for Cesarean Delivery.
Increasing the temperature of intrathecal local anesthetics has been shown to increase the speed of onset and block height of spinal anesthesia. However, how this influences dose requirement has not been fully quantified. The aim of this study was to determine and compare the effective dose for anesthesia for cesarean delivery in 50% of patients (ED 50 ) of intrathecal bupivacaine given at temperatures of 37 °C (body temperature) or 24 °C (room temperature). ⋯ Warming hyperbaric bupivacaine to body temperature reduced the dose requirement for spinal anesthesia for cesarean delivery by approximately 16% (95% CI, 7%-23%).
