Neuraxial anesthesia is the gold standard approach for cesarean delivery, offering surgical anesthesia while optimizing maternal and fetal outcomes. This video provides a stepwise demonstration of a combined spinal-epidural (CSE) technique for cesarean delivery. This technique covers patient positioning, identification of the appropriate interspace, sterile preparation, infiltration of local anesthetic, and spinal/epidural needle placement. For single-shot spinal (SSS), a spinal needle is advanced into the subarachnoid space, cerebrospinal fluid return is confirmed with aspiration, and intrathecal medication is administered. For CSE, an epidural needle is advanced into the epidural space using a loss-of-resistance technique, followed by spinal needle insertion through the epidural needle for intrathecal medication administration. This needle-through-needle technique concludes with epidural catheter insertion and securement. Indications and medication dosing for cesarean delivery are discussed for each technique.
Spinal Anesthesia for Ambulatory Hip and Knee Arthroplasty Procedures
Bruna Castro de Oliveira, MD

This educational video article details the technique of spinal anesthesia administration for total hip and knee arthroplasty. The presentation details key procedural elements, including anatomical landmarks, midline and paramedian techniques for spinal placement, equipment for spinal anesthesia, patient positioning and preparation, and local anesthetic selection. Spinal anesthesia offers distinct advantages for outpatient arthroplasty, including rapid onset, favorable operative conditions, and facilitation of same-day discharge. The video serves as a practical educational tool that reinforces evidence-based anesthetic practice and supports the continued advancement of safe, efficient care in ambulatory joint replacement surgery.

This video provides a step-by-step demonstration of preprocedural neuraxial ultrasound for lumbar neuraxial procedures. The film shows probe selection and orientation, sonoanatomy landmarks (sagittal and transverse views), measurement of skin-to-posterior complex depth, and skin marking. Indications and evidence for improved procedural accuracy and reduced needle passes are discussed. The technique is applicable to routine obstetric neuraxial procedures and is especially useful in patients with challenging surface landmarks or a history of difficult neuraxial placement.
