title: Prevalence of low back pain experienced after delivery with and without epidural analgesia: A non-randomised prospective direct and telephonic survey.
abstract: OBJECTIVE
  The most frequent concern of patients receiving epidural analgesia for labour pain relief is post-partum back pain. This survey was designed to assess the prevalence of post-partum backache with and without epidural analgesia among post-partum women.
  
  
  METHODS
  The study was conducted at a university teaching hospital and women presenting to labour room for labour and delivery formed the target population. A total of 482 women were recruited during the study period. Response rate was 95.4% and these cases were included in our statistical analysis. Two forms were designed for data collection before and after delivery; form I was filled by one of the investigators while form II was filled by a research assistant to prevent bias which included follow-up of back pain. The primary outcome variable was backache quantified with visual analogue scale score. Out of 460 women, 230 women received epidural analgesia for labour and 230 women had not.
  
  
  RESULTS
  The prevalence of post-partum back pain in epidural analgesia versus non epidural analgesia groups was 40.9% versus 40% on day one and 32.2% versus 35.2% after 1 week. However, after one and 3(rd) months follow-up, backache prevalence was less in epidural analgesia group (unadjusted odds ratio [OR]: 0.63; 95% confidence interval [CI]: 0.39-0.99) and (unadjustedd OR: 0.32; 95% CI: 0.15-0.69) respectively. The adjusted odd ratio was 0.59 at 1st month and 0.25 at 3rd month. There was no significant difference between the two groups in pain scores.
  
  
  CONCLUSIONS
  There was no association between the epidural analgesia and post-partum back pain.
