Abstract

The impact of fibromyalgia on the course of pregnancy is not clearly defined. We evaluate the frequency of FMS symptoms among full-term healthy pregnant women and the impact on the course of delivery. The 2011 modification of the ACR 2010 criteria for FMS diagnosis was used as well as the FIQ, SF-36 and AIMS questionnaires. The 1990 ACR classification criteria were documented. Data were collected relating to course of the delivery, induction, length of stage 1, 2 and 3 of delivery, epidural anesthesia, artificial rupture of membranes, instrumental delivery and cesarean section. A VAS recording pain intensity during delivery was documented. Out of 100 women recruited, 27 (27 %) fulfilled Modified FMS criteria. Only one of these women fulfilled ACR 1990 criteria, women who fulfilled the ACR criteria differed significantly from women who did not fulfill these criteria on a broad range of parameters including widespread pain and fatigue, social functioning, emotional well-being, role limitation and physical functioning. A significant correlation was found between length of stage 2 and results of the FIQ as well as with components of the SF-36. The intensity of pain during birth however was not correlated with the presence of FMS criteria. FMS symptoms were highly prevalent among healthy pregnant women at term. The presence of such symptoms may impact on the course of delivery and the need for anesthesia. Evaluating for features of centrally mediated pain may be of clinical relevance for physicians involved in the treatment of pregnant women.
