Did you ever think you would see a mother and child breast-feeding in an MRI?

I never met a baby I didn't like.

I didn't always appreciate how they behaved in the #NICU but with age I learned not to take it too personally.

In the NICU, time bends — minutes can feel like eternities, and eternities can change in a single breath.

Although darbepoetin for newborns 23-29 weeks increased RBCs and decreased transfusions sadly it didn’t translate into better neurodevelopmental outcome
The silver bullet remains elusive!

Study finds that non-pharmacological care prior to LISA for surfactant administration may be enough without giving fentanyl. No difference between saline or fentanyl on COMFORTNeo score

Is atropine really required in addition to fentanyl & succinylcholine prior to intubation to prevent severe bradycardia in neonates?

We found yes...

Severe bradycardia during the whole procedure was signif > in placebo vs atropine group; RR 6.3(95% CI 1.2 - 34.1)

Pilot study finds diaphragmatic thickness worsens with intubation in infants born < 28 wks but even > when sedation is given.
Pause & consider if sedation is required on the ventilator & ask if non-pharmacological strategies are maximized?

Permissive hypercapnia (60-75 mmHg & pH ≥ 7.20 vs (40-55 mmHg and pH ≥ 7.25) for 28 days from day 7-14 in #preemies may shorten the total days of ventilation but doesn't change the big outcome of survival without moderate to severe BPD

Even if survival is quite unlikely, I see the need of parents to at least try.
You lose 100% who aren’t resuscitated in the 500g range.
Parents may not know what lies ahead but they may be certain they don’t want to spend the rest of their lives asking “what if?”

Pilot study finds that fentanyl as sedation for newborns born < 28 weeks reduces diaphragmatic thickness at both end inspiration and expiration.
Does sedation impact not just drive but respiratory muscle function?
