Ultrasound-guided regional anesthesia for peripheral nerve blocks: an evidence-based outcome review.

Ultrasound-guided regional anesthesia (UGRA) has increased in popularity over the past 5 years. This interest is reflected by the plethora of publications devoted to technique development, as well as randomized and controlled trials. Despite the excitement around ultrasonography, skeptics argue that there is a lack of evidence-based medicine to support the unequivocal adoption of UGRA as a "standard of care.

Local anesthetic resistance in a pregnant patient with lumbosacral plexopathy.

BACKGROUND: We report a case of a patient with apparent resistance to local anesthetics. While similar cases of failure of regional anesthetics are often attributed to technical failure, the overall clinical presentation and history of this patient suggests a true resistance to local anesthetics. CASE PRESENTATION: This patient presented for elective cesarean section and the decision for regional anesthesia was made.
