Combined spinal Epidural anesthesia for anorectal surgery

ABSTRACT

This study presented the experience with a new combined spinal epidural system through which regional anesthesia was performed in 40 male patients undergoing anorectal surgery [hemorrhoids and fissure or perianal fistula]. The technique consists of two needles, a 16 G Touhy needle with a hole in its distal curve [backeys] and 26 G spinal needle which is passed through the back eye before being introduced into the subarachinoid space. The study found the back eye combined spinal-epidural system effective and simple to use. The Touhy needles with its back eye did not impede insertion of the epidural catheter and was suitable introducer for the 26 G spinal needle
