ABSTRACT
BACKGROUND: Various interventions have shown promise in reducing complications following accidental dural puncture. However, these have yet to be studied as a single, comprehensive protocol. The aim of this study is to compare outcomes associated with the use of a continuous spinal protocol for labor pain relief versus resiting the epidural catheter following accidental dural puncture. METHODS: We reviewed the charts of patients managed via our continuous spinal protocol and compared this group with patients for whom the epidural was resited following accidental dural puncture during the 5-year period prior to implementing our protocol. We assessed incidence of postdural puncture headache, epidural blood patch, frequency of catheter replacement, use of pressors, verbal pain scores at 0, 1, 2, 3, 4 hours following catheter placement, infection rates (meningitis/epidural abscess) and mode of delivery. RESULTS: There were 129 women in the continuous spinal protocol group and 52 in the resited epidural group. The incidence of postdural puncture headache was lower in the continuous spinal group versus the resited epidural group (21.7% vs 67.3%, p<0.001), and the incidence of epidural blood patch was lower in the continuous spinal group versus the resited epidural group (12.4% vs 50.0%, p<0.001). Verbal pain scores were consistently lower in the continuous spinal group compared with the resited epidural group at all time intervals studied. CONCLUSION: Patients managed via this continuous spinal protocol had significantly lower incidence of postdural puncture headache and epidural blood patch with more effective labor analgesia following accidental dural puncture.
