      Cystic fibrosis affects 1 in 1600-2500 live births and is inherited in an autosomal recessive manner. It primarily involves the respiratory, gastrointestinal and reproductive tracts, with impaired clearance of, and obstruction by, increasingly viscous secretions. Severe respiratory disease, diabetes and gastro-oesophageal reflux may result. Improvements in medical management and survival of cystic fibrosis patients means more are committing to pregnancies. Although guidance for anaesthesia in this patient group is available, management and outcome data associated with more severe cases are sparse. Patients with severe cystic fibrosis require multidisciplinary input and should be managed in a tertiary referral centre. Close monitoring of respiratory function and preoperative optimisation during pregnancy are mandatory. The risk of preterm labour and delivery is increased. Pregnancy and delivery can be managed successfully, even in patients with FEV1 <40% predicted. Neuraxial anaesthesia and analgesia should be the technique of choice for delivery. Postoperative care should be carried out in a critical care setting with the provision of postoperative ventilation if necessary.
    • A randomised controlled trial using the Epidrum for labour epidurals.

      The aim of our study was to determine if using the Epidrum to site epidurals improves success and reduces morbidity. Three hundred parturients requesting epidural analgesia for labour were enrolled. 150 subjects had their epidural sited using Epidrum and 150 using standard technique. We recorded subject demographics, operator experience, number of attempts, Accidental Dural Puncture rate, rate of failure to site epidural catheter, rate of failure of analgesia, Post Dural Puncture Headache and Epidural Blood Patch rates. Failure rate in Epidrum group was 9/150 (6%) vs 0 (0%) in the Control group (P = 0.003). There were four (2.66%) accidental dural punctures in the Epidrum group and none in the Control group (P = 0.060), and 2 epidurals out of 150 (1.33%) in Epidrum group were re-sited, versus 3/150 (2%) in the control group (P = 1.000). The results of our study do not suggest that using Epidrum improves success or reduces morbidity.
