Combined Spinal and Epidural Kit

1. Needle-through-needle design – Allows sequential epidural placement and spinal injection through a single interspace, minimizing dural trauma and reducing the risk of post-dural puncture headache (PDPH) compared to separate-site techniques. 2. Pre-assembled components for procedural efficiency – Includes epidural needle, spinal needle (typically 25G–27G pencil point or Quincke type), epidural catheter, low-loss syringe, filter, and adhesive patch, all sterile and ready for immediate use, reducing setup time and contamination risk. 3. Back-eye or hole-at-the-tip epidural needle – Facilitates smooth passage of the long spinal needle while keeping the epidural needle in place; some designs feature a dedicated spinal needle exit port that directs the needle away from the epidural catheter pathway, preventing catheter damage or shearing.
