[Evaluation of the demand for access to peridural obstetrical anesthesia in maternity units]

This prospective study was initiated by a multicentric work. Each participating hospital, was asked to give data about 20 patients. Because of the importance of these informations for our practice, we decided to continue the evaluation, using the same inquiry, until 200 patients were enrolled.

An independent student (resident pharmacist), using a preprinted inquiry from interviewed two hundred consecutive in the, 48 hours after delivery in order to evaluate the following aspects: reasons to wish an epidural analgesia (EA) or not, modalities of achievement of EA. Statistical study: Chi-square and logistic regression.

Among 199 analyzable files, 137 women wished for an EA (68.5%) but in only 90 the procedure was performed. Reasons for non-achievement of EA were the following: labour too advanced (43/47), obstetrical contraindication (2/47), anaesthesiologist non available (2/47). Delay between arrival at hospital and EA performance was 5 h 30 during daytime and 4 h 40 during nighttime. Delay and rate of EA achievement were not different between day and night time. Logistic regression analysis found following criteria related to: Wish for an EA analgesia: anaesthesiology consultation (OR = 193, p < 0.001), nulliparity (OR = 4, p < 0.002) and satisfactory information about EA (OR 35, p = 0.051). Achievement of EA: nulliparity (OR 38, p < 0.002), length of labour (OR = 1.01/min, p < 0.001).

This study underlined the fact that one third of parturients do not wish for an epidural analgesia, mainly out of fear for neurological complications. When the obstetrician indicated an EA, our organisation allowed its achievement in 98% of cases. The latency between arrival and EA should be shortened.
