    Abstract:
    BACKGROUND: Dural mater is punctured by using a spinal needle without drugs administrated into intrathecal space directly in dural puncture epidural (DPE) analgesia. OBJECTIVE: This study aimed to summarize the evidence of benefits and risks of DPE analgesia with 25-G spinal needles for labor pain relief. METHODS: DPE analgesia with EP analgesia for labor pain relief were systematically searched. The Embase, MEDLINE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science databases were systematically searched till 6th November 2022 to find out randomized controlled trials (RCTs) comparing DPE (using 25-G spinal needles) with conventional epidural (EP) analgesia. The risk of bias was assessed with the Cochrane tool. Risk ratio, mean difference, and 95% confidence intervals were calculated. RESULTS: Seven RCTs with 761 parturients were identified. Pool data showed that DPE technique was associated with shorter time to pain score ⩽ 3/10, higher percentage with pain score ⩽ 3/10 at 10 min and 20 min, lower incidence of epidural top-up bolus and no S2 block, higher incidence of bilateral S2 blockade at 10 min and during labor, lower incidence of epidural top-up bolus and incidence of asymmetric block. No statistical difference in side effect and parturient satisfaction between DPE and EP technique. CONCLUSION: DPE technique with 25-G spinal needles was associated with faster analgesia onset and sacral coverage, greater sacral spread, lesser requirement of epidural top-up and lower incidence of asymmetric block. DPE technique with 25-G spinal needles showed a greater benefit to parturients.
