Randomized Controlled Trial Comparative Study
The analgesic effects of intrathecal morphine in comparison with ultrasound-guided transversus abdominis plane block after caesarean section: a randomised controlled trial at a Ugandan regional referral hospital.
What did they do?
The researchers randomised 130 women to 10 mg intrathecal hyperbaric bupivacaine plus an ultrasound-guided TAP block, or to 10mg intrathecal hyperbaric bupivacaine with 100 mcg morphine, plus a sham TAP block.
And they found
There was no difference between either group for satisfaction, analgesia or adverse effects. They concluded that in the context of intrathecal morphine availability, there is no benefit from TAP block, although TAP block can produce comparable analgesia if IT morphine is not used.
What’s particularly interesting...
Unlike the majority of obstetric anaesthesia research, this study comes from the same environment that also manages the bulk of global deliveries: low and medium income countries.
It is also an important reminder that not only are techniques used in wealthier countries applicable and translatable to lower-resource settings, but so is high quality research – and as with all research, context is everything.
