Lower incidence of post-dural puncture headache with spinal catheterization after accidental dural puncture in obstetric patients

摘要: Background Accidental dural puncture (ADP) and post-dural headache (PDPH) are important complications of obstetric regional anesthesia. Inserting the catheter intrathecally after ADP to prevent PDPH has gained popularity. Nonetheless, data on effect an intrathecal epidural blood patch (EBP) rates mixed. Our primary objective was examine if spinal catheterization reduces incidence in patients. Methods Anesthetic records 29,749 blocks performed between January 1997 July 2013 were analyzed retrospectively. In all containing component, 18-gauge needles used. All patients who experienced a witnessed or without identified. Data from with prolonged compared. Results There 128 events (0.43%). Following known ADP, 39 women had placed at different level 89 (20-gauge) for least 24 h. Sixty-one developed observed (48%). Prolonged placement significantly reduced 42% compared 62% those have re-sited epidurally [odds ratio = 2.3 (95% confidence interval 1.04–4.86); P = 0.04]. Conclusions The patching is similar previously published studies. After inserting PDPH.
