Combined spinal-epidural anesthesia [CSEA] single space technique [SST]

ABSTRACT

Combined spinal-epidural anaesthesia in a single space has been used since 1981 on 14816 patients. Lumbar [L] 2-3 or L3-4 space was punctured by tuohy needle. Spinal needle [25 or 26G] was then passed through epidural needle while its bevel was in caudal position in the epidural space. After injecting local anaesthetic [3.5 ml bupivacain] through spinal needle once it has pierced the subarachnoid space, spinal needle was taken out. Epidural catheter was passed after turning the bevel of epidural needle cephalad. Segmental spread was assessed by pinprick. Advantages of both spinal-epidural anaesthesia has been obtained by this technique apart from post operative pain relief
