"Can the baby be given pain relief? No. Current research shows that the sensory structures are not developed enough or specialized enough to respond to pain in a fetus of less than 24 weeks. See question on ‘Will the fetus/baby feel pain?’ In later pregnancy, when the fetus/baby is over 24 weeks, we do not yet have enough knowledge to know if providing pain relief would be beneficial. This means that it is extremely difficult to know what kind of pain relief should be used, how any pain relief should be given and whether it would be safe and effective. If pain relief was to reach the baby inside the womb, this would mean giving the mother larger and potentially dangerous doses to try and make sure enough crossed the placenta to the baby. This may cause more harm than benefit. Injecting pain relief drugs directly into the baby would increase the risk of miscarriage."
