Irn# (b)(4)
this incident took place in france (polynésie).An epidural catheter was to be inserted in case additional anesthetic dosing
became necessary and to provide postoperative epidural analgesia.After completion of the spinal anesthesia, an attempt was made to withdraw the spinal needle (sprotte) from the epidural
needle (tuohy).The metallic portion of the spinal needle remained lodged inside the epidural needle while both were
still in the patient's back, with no possibility of grasping it.The plastic hub of the spinal needle, to which the injection
syringe is attached and locked, detached and fell to the floor.As there was no longer any external access point to the metallic portion of the spinal needle, it became necessary to
remove the epidural needle in order to safely withdraw the spinal needle from the patient's back.Consequently, it was no longer possible to use the epidural needle to thread an epidural catheter and administer
additional anesthetic doses should the surgical procedure be prolonged, nor to provide postoperative epidural analgesia.).
