Details and patient eligibility
About
* The objective of the study: to assess the impact of a proactive policy of offering EA at the start of labour as compared to a restrictive policy or care as usual.
* Study design: It concerns a multicentre randomised open label trial.
* Study population: Term nulliparous and multiparous women with a child in cephalic presentation, and without contraindications for vaginal labour or EA.
* Intervention: Women will be allocated to the EA group or the care-as-usual group. In the EA group, women are given an EA as soon as they are in labour. In the care-as-usual (restrictive) group, women receive pain relief only on their explicit request.
Full description
Labour pain can be regarded as one of the most serious kinds of pain.In many countries labour pain is effectively treated on request of the labouring woman. In The Netherlands, labour pain has been traditionally approached conservatively. However, this policy is rapidly changing into effective treatments on request.Epidural analgesia (EA) has been proven to be one of the most effective methods of pain relief during labour.In addition, EA leads to increased patient satisfaction. Compared with other (or no) methods of pain relief, however, EA is associated with more use of oxytocin, a longer second stage of labour, and more instrumental vaginal deliveries. Other possible adverse effects in labouring women during EA are hypotension, motor block, urine retention, and fever. These complications and adverse effects are possible reasons, why EA is still not widely advised and accepted in The Netherlands.However, the question whether these adverse effects are caused by the EA, or that the observations are biased is still unanswered. The studies that have been performed to address these items are not applicable to the general population of women delivering a child, as they were all performed in women in strong need of pain relief.Generally, the need for pain relief is increased when progression of labour is difficult, for example in case of a relatively great child or ineffective contractions, especially in nulliparous women. It is well known that in this group of labouring women, also without EA, obstetrical problems are increased. On the other hand, a multivariable analysis of factors that are associated with an arrest of labour indicates, that women with EA have a decreased risk of arrest of labour. At present, randomized controlled trials that study the obstetrical consequences of EA in nulliparous women without strong need of pain relief are lacking. Besides that, only a few studies have extensively looked at the preference of women for EA. It seems that parity status, the fear of the side effects of EA, pain catastrophizing, the desire to have a pain-free childbirth, positive experiences with EA of family and friends influence the odds of choosing EA. So, based on the international literature, the ongoing increase in The Netherlands of EA's on maternal request during delivery may result in more obstetrical problems and increased health costs. Of course a change in pain treatment surrounding birth will have an impact for the women in labour, as well as for the society. On the one hand the costs of care are likely to increase due to EA, as EA is more expensive and might lead to an augmentation of medical complications, on the other hand in the EA-group women will have less pain while in labour as compared to the non-EA group. The question remains, whether this can be counteracted by a proactive policy of offering EA before explicit maternal request for pain relief in the absence of obstetrical problems. It is assumed, that a proactive policy might result in effective pain reduction and increased patient satisfaction without increased obstetrical problems and without increased health costs.
