Gluteal biopolymer injections can migrate unpredictably into the lumbosacral region, creating potential barriers to neuraxial anesthesia and risking contamination of neuraxial structures. We report a case of successful epidural anesthesia in a 32-year-old primigravida with magnetic resonance imaging (MRI)-confirmed biopolymer migration to L5-S1. An epidural was placed at L1-L2 under ultrasound guidance during labor and subsequently used uneventfully for cesarean delivery. This case demonstrates that neuraxial anesthesia may be feasible when imaging is used to identify safe procedural sites and highlights the importance of preprocedural planning to optimize maternal and neonatal outcomes in patients with migrated biopolymers.

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
