OBJECTIVE: To determine whether epidural anaesthesia during labour and delivery is a risk factor for postpartum back pain. DESIGN: Prospective cohort study with follow up at one day, seven days, and six weeks after delivery. SETTING: Teaching hospital in Montreal. SUBJECTS: 329 women who delivered a live infant(s) during the study period. Exclusion criteria were back pain before pregnancy and delivery by elective caesarean section. INTERVENTION: Epidural anaesthesia during labour and delivery. MAIN OUTCOME MEASURES AND RESULTS: The primary outcome variable was development of postpartum low back pain. Back pain was quantified with self reports (yes/no), a pain score (numeric rating scale), and degree of interference with daily activities. Of the 329 women, 164 received epidural anaesthesia during labour and 165 did not. The incidence of low back pain in epidural v non-epidural group was 53% v 43% on day one; 21% on day seven; and 14% v 7% at six weeks. The relative risk for low back pain (epidural v non-epidural) adjusted for parity, delivery, ethnicity, and weight was 1.76 (95% confidence interval 1.06 to 2.92) on day one; 1.00 (0.54 to 1.86) on day seven; and 2.22 (0.89 to 5.53) at six weeks. There were no differences between the two groups in pain scores or the frequency of interference with daily activities. Similar results were obtained in the subgroup of women with low back pain of new onset--that is, those women with no back pain during their pregnancy. CONCLUSIONS: Postpartum low back pain was common but decreased considerably over the short term. The association between epidural anaesthesia and postpartum low back pain was inconsistent over time with a significantly increased risk of low back pain (epidural v non-epidural) noted only on the first day after delivery.

We present an unusual case of postoperative headache in a child after an epidural block. A seven-year-old girl (ASA 1) was scheduled to undergo a urological procedure under general anaesthesia combined with an epidural technique for intra- and postoperative analgesia. Although there was no evidence of dural puncture when the block was performed, the patient developed a headache postoperatively. The headache, which was accompanied by neck pain, appeared in the sitting or standing position and was relieved by decubitus. According to the mother, her child had never complained of those symptoms in the past. After independent evaluation by an anaesthetist and a neurologist, a postdural puncture headache (PDPH) was considered the most likely diagnosis. As oral analgesics failed to provide relief, and epidural blood patch (EBP) using 10 ml autologous blood was performed under light sedation. This was followed by resolution of the symptoms. Epidural injections of opioids and local anaesthetics are becoming increasingly popular for pain management in children. This implies that there may be an increasing number of unintentional dural punctures that may result in more PDPHs in children. Epidural blood patches are effective in treating PDPHs in adults but their use has been reported very rarely in children. Resolution of the patient's symptoms following EBP supported the diagnosis while illustrating that EBP can be useful in the treatment of PDPH in children.
