Complementary to a previous publication related to pediatric extremity and trunk blockade, the authors present a comprehensive narrative review of the literature pertaining to techniques described and outcomes evaluated for ultrasound imaging in pediatric neuraxial anesthesia. The sonoanatomy related to each block is also described and illustrated to serve as a foundation for better understanding the block techniques described. ⋯ Particularly, in young infants, direct visualization of the needle and catheter tip may be possible, whereas in older children surrogate markers including the displacement of dura mater by the injection of fluid may be necessary for confirming needle and catheter placement. More outcome-based, prospective, randomized, controlled trials are required to prove the benefits of ultrasound when compared with conventional methods.

Multicenter Study
Incidence and root cause analysis of wrong-site pain management procedures: a multicenter study.
Medical errors exact an inordinate toll on healthcare costs. One of the most publicized and analyzed type of medical error is wrong-site surgery. Yet, despite the burgeoning number of procedures performed, no literature exists on wrong-site pain management injections. The purpose of this study was to estimate the relative incidence and determine the causes of wrong-site pain management procedures. ⋯ Wrong-site nerve blocks occur more frequently in pain management centers than has previously been acknowledged. Adaptation of the universal protocol to nerve blocks and strict adherence to widely accepted guidelines may prevent wrong-site interventional pain procedures.

We tested the hypothesis that in newborn rats, sevoflurane may cause seizures, neurotoxicity, and impairment in synaptic plasticity-effects that may be diminished by the Na-K-2Cl cotransporter 1 inhibitor, bumetanide. ⋯ These results support the possibility that excitatory output of sevoflurane-potentiated gamma-aminobutyric acid type A/glycine systems may contribute to epileptogenic and neurotoxic effects in early postnatal rats.
