Ultrasound-assisted neuraxial techniques have been used with increasing frequency to facilitate central neuraxial blockade. Advocates of the technique believe the use of ultrasound can enhance the safety and efficacy of neuraxial procedures by improving identification of the correct interspace and decreasing unnecessary needle movements. A recent review also found improved safety with ultrasound-assisted neuraxial procedures. However, it is still unclear as to which subpopulation benefits the most from the use of ultrasound. This randomized controlled trial aimed to determine the efficacy of performing preprocedural neuraxial ultrasound in women undergoing cesarean section with combined spinal-epidural (CSE) anesthesia. It also sought to identify factors associated with technical success of CSE.
