HILTON HEAD ISLAND, S.C. -- Women who receive walking or "mobile" epidurals are more likely to void spontaneously during labor and are less dependent on urinary catheterization than women on traditional epidural regimens, Dr. Matt Wilson said at the annual meeting of the Society for Obstetric Anesthesia and Perinatology.
Preserved bladder function may help explain why women given walking epidurals have higher rates of spontaneous vaginal births and lower rates of instrumental delivery, compared with traditional epidural, said Dr. Wilson, who conducted the study at the University of Birmingham (England).
The effect of epiclurals on bladder function is still controversial. Some studies have shown that bladder function remains abnormal up to 8 hours after epidural use. During this period, the bladder is vulnerable to over-distension injury Also it is not clear whether this injury has a long-term effect on urinary incontinence.
The current analysis was based on data from the Comparative Obstetric Mobile Epidural Trial (COMET). In that study, 1,054 nulliparous women were randomized to receive either traditional epidural analgesia or one of two mobile regimens: combined spinal epidural (CSE) or low-dose infusion (LDI).
Overall, the rates of women in all three groups requiring intermittent catheterization at some point during labor were similar: traditional (79%), CSE (68%), and LDI (62%).
But even when a catheter was required during labor, women ...
