A prospective cohort study was conducted among subjects who underwent elective caesarean section under spinal anaesthesia, with morphine patient-controlled analgesia administered for 24 hours postoperatively. Perioperative, surgical and obstetric factors were investigated prospectively. Phone surveys were conducted to identify risk factors associated with chronic pain.<\/jats:p>\n                  <jats:p>A total of 857 subjects completed both the perioperative study and phone survey. The incidence of wound scar pain for three months after surgery was 9.2% (79). Of the 51 subjects with persistent pain at the time of subsequent survey, 9.8% (n=5) had constant pain, 9.8% (n=5) had daily pain and 23.5% (n=12) had pain intermittently, at an interval of days. The independent risk factors for development of chronic pain were higher pain scores recalled in the immediate postoperative period (odds ratio [OR, 95% confidence interval] 1.348 [1.219 to 1.490], P=0.0001), pain present elsewhere (OR 2.471 [1.485 to 4.112], P=0.001) and non-private insurance status (OR 1.679 [1.034 to 2.727], P=0.036). The two most common sites of pain other than wound pain were back pain (n=316) and migraine (n=87).<\/jats:p>","DOI":"10.1177\/0310057x0903700513","type":"journal-article","created":{"date-parts":[[2019,1,14]],"date-time":"2019-01-14T17:38:17Z","timestamp":1547487497000},"page":"748-752","source":"Crossref","is-referenced-by-count":97,"title":["Incidence and Risk Factors for Chronic Pain after Caesarean Section under Spinal Anaesthesia"],"prefix":"10.1177","volume":"37","author":[{"given":"B.
