Why the study?
Does maintaining selective extradural analgesia throughout labour improve pain and obstetric outcomes in parturients compared to allowing the block to wear off for the second stage?

Maintaining extradural analgesia throughout the second stage of labor provides better pain relief and improves obstetric outcomes compared to letting the block wear off.
Selective analgesia maintenance was associated with better pain and obstetric outcomes; hypothesis-generating and should not yet change practice.
Two groups of parturients who had received selective extradural analgesia were studied. In Group A patients the regional block was allowed to wear off for the second stage of labour whereas in Group B patients' analgesia was maintained throughout labour. The maintenance of selective analgesia was of positive benefit to the mothers. They experienced much less pain, labour was not prolonged, dosage of bupivacaine was not increased, the forceps delivery rate was lower and there were fewer persistent malrotations.
