Epidural blockade, spinal blockade,
pudendal nerve blockade, infiltration of the perineum, no pain relief. Results. In
all, 32.4% primiparas and 51.4% multiparas who had a vacuum-assisted delivery
had this without potent pain relief such as epidural blockade, spinal blockade or
pudendal nerve block. When infiltration was added as a method for pain relief,
18% were still delivered without pain relief. Multiparas were more likely than
primiparas to be delivered without potent pain relief, odds ratio (OR) 2.29 95%
confidence interval (CI) (2.20–2.38). Compared with women delivered by
vacuum extraction due to prolonged labor, those with signs of fetal distress
were more likely to be delivered without potent pain relief
