Factors associated with failed epidural blood patch after accidental dural puncture in obstetrics: a prospective, multicentre, international cohort study.

Background: Epidural blood patch is commonly used for management of post-dural puncture headache after accidental dural puncture. The primary aim was to determine factors associated with failed epidural blood patch.

Methods: In this prospective, multicentre, international cohort study, parturients ≥18 yr receiving an epidural blood patch for treatment of post-dural puncture headache were included.

Management practices for postdural puncture headache in obstetrics: a prospective, international, cohort study.

Background: Accidental dural puncture is an uncommon complication of epidural analgesia and can cause postdural puncture headache (PDPH). We aimed to describe management practices and outcomes after PDPH treated by epidural blood patch (EBP) or no EBP.

Methods: Following ethics committee approval, patients who developed PDPH after accidental dural puncture were recruited from participating countries and divided into two groups, those receiving EBP or no EBP.

Current use of ultrasound for central vascular access in children and infants in the Nordic countries--a cross-sectional study.

Purpose: The use of ultrasound (US) guidance for central vascular access in children has been advocated as a safer approach compared to traditional landmark techniques. We therefore collected data on the current use of US for central vascular access in children and infants in the Nordic countries.

Methods: A cross-sectional survey using an online questionnaire was distributed to one anaesthesiologist at every hospital in the Nordic countries; a total of 177 anaesthesiologists were contacted from July till August 2012.
