WE have been using 20 mcg of Inj. Fentanyl( Other molecules are not available in India) Sufentanyl is there but very difficult to acquire.
WE give 20 mcg Fentanyl IV and keep the rest of 80 mg diluted in a syringe. We keep giving it IV as 2 or 3 mcg demand dose. I have never connected a syringe pump on a patient in labour, that too a late stage. So we keep giving demand dose only.
It has worked well, though not sufficient experience to present it.
In no case there was foetal dystress. Though we keep Nalox available.
Can any one present their experience.
Gases like Entonox are only heard of over here.
I did read about Sevo for labour. Will try it out.
