Painless labour

Is it possible?
yes
so many studies has been done on this topic.
meta analysis says painless labour is quite possible in centres where anaesthetist, gynecologist, patient ,nurse ,paediatrician work as a team round the clock .
nitrous oxide plus oxygen combination -patient controlled/doctor decided dose anaesthesia
ketamine
fortwin plus phenargan
tramadol
some GA drugs
epidural top ups with bupivacaine
many options are available.
risks complications must be outweighed with advantages then only it becomes popularise.
