    Abstract:
    OBJECTIVE: The aim of this meta-analysis was to evaluate the postdural puncture headache after spinal anesthesia with Whitacre spinal needles compared with Quincke spine needles. METHODS: We searched several databases, including PubMed, Embase, ISI Web of Knowledge, and Cochrane Central Register of Controlled Trials until October 10th, 2014, for randomized controlled trials that compared spinal anesthesia with Whitacre spinal needles or Quincke spine needles for postdural puncture headache. Two reviewers independently screened the literature, assessed the risk for bias and extracted data. We used RevMan 5.3 software to perform the meta-analysis. Studies were included for the main end points if they addressed the following: frequency of postdural puncture headache, severity of postdural puncture headache as assessed by limitation of activities, and frequency of epidural blood patch. RESULTS: Nine randomized controlled trials were included for meta-analysis. The meta-analysis showed that spinal anesthesia with Whitacre spinal needles achieved lower incidence of postdural puncture headache(RR 0.34; 95% CI [0.22, 0.52]; P < .00001); in addition, the severity of postdural puncture headache was lower in the Whitacre spinal needle group (RR 0.32; 95% CI [0.16, 0.66]; P = .002). Furthermore, the frequency of an epidural blood patch in the Whitacre spinal needle group was lower compared with that in the Quincke spine needle group (RR 0.15; 95% CI [0.04, 0.51]; P = .002). CONCLUSION: We suggest the Whitacre spinal needles as a superior choice for spinal anesthesia compared with Quincke spine needles.
