The Arrow® SureBlock® Spinal Anesthesia Collection features the Sprotte® spinal needle, which has been proven to minimize the incidence of postdural puncture headaches. Also, the spinal anesthesia procedure time can be significantly reduced by way of the Sprotte® needle's uniquely polished inner lumen and optimal hub design, which provide for rapid cerebrospinal fluid return after insertion. The results are enhanced comfort and safety for the patient and greater ease of use and reliability for the anesthesia provider
