BACKGROUND: Reported rates of unintended dural puncture during performance of continuous epidural anesthesia (CEA) or combined spinal-epidural anesthesia (CSEA) have remained steady at approximately 0.5% to 1% since the 1970s.
METHODS: A modified method of inserting the Tuohy epidural catheterization needle was used during performance of CSEA in 393 parturients. A single staff/faculty anesthesiologist performed or supervised resident use of a flush-measure-check-advance Tuohy needle insertion algorithm.
RESULTS: The rate of evident Tuohy needle dural puncture during the series was 0%. One parturient experienced a post-dural puncture headache possibly because of intentional subarachnoid puncture with a very small diameter (25 gauge) needle during 2 CSEAs. In 19 parturients, the initial spinal anesthesia portion of CSEA failed, prompting conversion to CEA in 18 parturients and to spinal anesthesia in 1 parturient.
CONCLUSION: The use of a flush-measure-check-advance Tuohy needle insertion algorithm to reduce the likelihood of unintended dural puncture during performance of CSEA in parturients deserves further study.
