Technique for intraoperative cerebrospinal fluid drainage ROBERTS. HOOD, M.D., ANDHARRYR. BOYD, M.D. Section of Neurosurgery, Saint Joseph Hospital, Denver, Colorado
ERTAINintracranial surgical procedures are facilitated technically by drainage of cerebrospinal fluid. For intraoperative cerebrospinal fluid drainage, one can employ a system of closed drainage via lumbar puncture. For these procedures we use the Cuatico myelography needle,* because of its relatively safe inner cannula with multiple small openings. When secured in place, the cannula is connected by sterile intravenous tubing to an empty bottle. This system provides a simple, reliable method of intraoperative cerebrospinal fluid drainage.
