Sr. Furst et Ls. Reisner, RISK OF HIGH SPINAL-ANESTHESIA FOLLOWING FAILED EPIDURAL BLOCK FOR CESAREAN DELIVERY, Journal of clinical anesthesia, 7(1), 1995, pp. 71-74
Recent case reports suggest there may be an increased risk of abnormal
ly high blockade (''high spinal'') from subarachnoid anesthesia if it
is performed immediately after epidural anesthesia. We describe two ca
ses of high spinal anesthesia following failed epidural block in obste
tric patients scheduled for cesarean delivery. Using a retrospective c
hart review, we estimate the incidence of high spinal anesthesia to be
11% in patients after prior failed epidural blockade versus fewer tha
n 1% in patients undergoing spinal anesthesia alone.
