Although there remains much conflicting evidence, largely of a low-quality observational nature, the highest quality evidence to date refutes assertions that epidural fentanyl reduces breastfeeding rates.
Notably Lee et al.’s 2017 RCT of over 300 women showed no effect of epidural fentanyl up to 2 mcg/mL and successful maternal breastfeeding up to 6 weeks.summary
An extensive collection of research debunking a range of myths and misconceptions regarding the way we use neuromuscular blocking drugs.
- Myth 1: Modern relaxants are so reliable and predictable that monitoring is unnecessary.
- Myth 2: Post-op residual paralysis is neither common or important.
- Myth 3: Post-op residual paralysis is easy to identify.
- Myth 4: Sugammadex makes residual paralysis a non-issue. (it might, but only if it is routinely available and used!)
- Myth 5: Using propofol and remifentanil we can avoid relaxants for intubation all together.
- Myth 6: Neuromuscular blockade has no effect on BIS.
And bonus myth: deep relaxation is necessary for improving surgical access during laparoscopy.summary

Possibly... but with some important caveats.
“Sugammadex is likely the most exciting drug in clinical neuromuscular pharmacology since the introduction of atracurium and vecuronium in the middle 1980s.” – RD Miller (2007).
Sugammadex (Bridion®) is a remarkable drug – and the anaesthesia community has moved very quickly to embrace the potential of this first ‘selective relaxant binding agent’ (SRBA), despite it’s considerable cost.
Sugammadex offers a new and improved way of reversing aminosteroid muscle relaxation, in particular from rocuronium. The speed at which it reverses even profound neuromuscular blockade is incredible and potentially life saving. Sugammadex’s onset is 10 times faster than neostigmine and three times faster than edrophonium.
Though beyond the parlour-trick of speedy action, or the possibility of rescuing a cannot-intubate-cannot-ventilate crisis – the biggest benefit of sugammadex for our patients may be in the dramatic reduction of post-operative residual paralysis. A common problem with serious consequences that the anaesthetic community has ignored for far too long.summary
