Heart rate versus age?
Good question! This systematic review on heart rates in children clearly shows the decline: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3789232/ To be honest, I don't know exactly the underlying mechanisms behind, but I suppose it may be related to both the autonomic drive (symp/parasymp), and that HR is a more important factor for cardiac output during infancy than later in life. Anyone else knowing more of basic physiology than I do ?

Priming Insulin infusions
@ChantalNICU I suppose there could be variations, this is the Stockholm version

Priming Insulin infusions
@ChantalNICU Sorry for the delay... (yes, I had forgotten ) this is the written guideline: after preparation, the pumpsyringe and tubings are filled and kept for 20min. Then the tubings are flushed with the solution and then connected to the patient.

Erythropoietin role for neuroprotection in neonates with hypoxic ischemic encephalopathy
Check out this blog post by @AllThingsNeonatal Myself, I must admit I have no experience at all of erythropoetin

Respiratory distress in neonates of smoker mothers
Same here - although maternal smoking is less prevalent nowadays, we have/do not managed infants differently. Although smoking is related to preterm birth as such (see for example https://www.ncbi.nlm.nih.gov/pubmed/15901269) - my personal experience is not that maternal smoking would (as such) relate to severity of respiratory morbidity.

Thanks I feel much grateful
Thanks so much for your feedback And, it is really all members, like you @tarek that "create" the content and the athmosphere by sharing expertise and experiences. Without that, the would be no community.

ET tube fixation methods
I got the advice on this device some years ago from a US-based RT. It is very easy to adjust the tube position as the tube is secured with velcro over metal "nabs". Don't know if it MR-safe though (manufacturer would know). For smaller preterms (like <1000g) the "tape plates" are too big. And care in high incubator humidity works less well, the tape gets loose. But overall and especially for term infants needing short-term invasive ventilation, this device works really well IMHO. The Karolinska level-3 NICU use tape in a new fashion, I think there is a video clip on Vimeo - will check out next week at work if I can share it here

Premedication before INSURE
We use it to reduce cardiovasc instability. See ref's below: https://www.ncbi.nlm.nih.gov/pubmed/6747766/ https://www.ncbi.nlm.nih.gov/pubmed/15470200

Priming Insulin infusions
@ChantalNICU thanks for posting! Wished I could share my own experience but it is very small... and now I work in a level-2 context. Just wanted to share 1) the video from the 2019 Meetup (below), 2) the hyperglycemia protocol from Sydney (https://www.slhd.nsw.gov.au/RPA/neonatal/protocols.html) and 3) the Auckland insulin guideline (http://www.adhb.govt.nz/newborn/DrugProtocols/InsulinPharmacology.htm) I can check with my level-3 colleagues in Stockholm after the summer vacation, if they have their own local guideline.

Premedication before INSURE
We practise pre-med for INSURE (atropin+fentanyl+pento and some use celo) - my experience is good with regards to cardiovasc and respiratory stability. But as @Nathan Sundgren says, we don't premed if we need to do INSURE right after delivery. Around here, the INSURE procedure also means pre-med, while LISA/MIST is the term used when surfactant is given without pre-med. Originally, when LISA/MIST was first done and studied by Angela Kribs and co-workers (https://www.ncbi.nlm.nih.gov/pubmed/17359406; https://www.ncbi.nlm.nih.gov/pubmed/18298776; https://www.ncbi.nlm.nih.gov/pubmed/18298776) I think their idea was to minimize any drug-related impact on the breathing drive. So they tested with no drugs and it worked well for them. I know many share this experience, that surfactant can be instilled without any pre-med. I personally feel concerned about the laryngoscopy as such, I believe atropine and analgesics would still have a place also in LISA/MIST. And for younger colleagues less experienced with laryngoscopy and intubation, I think the procedure may also be more uncomfortable for infants not given analgesia.

What really constitutes Extrauterine growth restriction(EUGR)
@bimalc Yes, we use the Miris milk analyzer. Our hospital runs the Milk Bank for the Stockholm region , so we have all this inhouse (and do milk analyses for all other hospitals as well). Mothers start pumping usually day.1 so after a week or so, most preterm infants get their own mother's milk. Until then, from the milk bank. All milk bank batches are analysed, and mother's own milk is analysed after ~10 days and then weekly or bi-weekly. A small amount of each pumping (1-2 ml I think) is collected during 24h and this selection is analysed. With the software Nutrium (https://www.nutrium.se/, also a small Swe company BTW, started by a neonatologist in Umeå) we input the milk spec's and then "add" the fortifications in the software, to tailor it per baby. We are directed by the growth curve and also the recommendations (ESPGHAN etc). The software gives a very detailed feedback, all macro and micro-nutrients are marked red, yellow and green depending if ("too little/much", "close", and "within recommendations"). If milk is not analysed, we use a "sham" specification, one for "immature/early" and one for "mature/late" breast milk until we have data on the actual batch of breast milk. So, we spend a some time and resources on nutrition although it sometimes feel we over-engineer, we really aim to optimize nutrition on an individual basis. And the whole setup has become integrated in our daily routines, so it works smoothly. There are some publications where this detailed nutrition data (extracted from this software) has been used, the second ref also showing that many extrem preterm infants get malnourished during the first weeks of life. https://www.ncbi.nlm.nih.gov/pubmed/26690864 https://www.ncbi.nlm.nih.gov/pubmed/23855971

What really constitutes Extrauterine growth restriction(EUGR)
Dear @Akash Sharma, thanks for posting about this! We spend much time on nutrition, but personally, I tend to feel confused on this higher level. Some infants grow well, while some infants grow poorly whatever we do... We use a computerized program (https://www.nutrium.se/) and make individual fortification to every preterm infant. Weights are plotted on a growth curve (starting at 24 wks) and we aim to achieve a "normal growth velocity". For SGA infants we tend to think about the patophysiology, if it is IUGR due to placental reasons (like pre-eclampsia), we think there is a potential for this baby to be AGA. So we expect catch-up growth and (if needed) try to promote that with fortifications. We don't use the term EUGR in our unit, but we strive to get all infant withn the "normal" weight range, for us that means that we want infants within +/- 2 SD on the growth chart. Coming to your question... we tend to use the growth-chart-definition of poor growth rather than body-composition analyses or clinical endpoints (which are also more like outcomes of growth)

Parental Transport Feedback
To my knowledge: around here, parental feedback is not collected in a structured way. However, we have a strategy for cross-checking with parents after arrival to us. Our experience is that it takes some time for parents to "overcome" a transfer, even when their infant is well and doing fine and transferred to a lower-level NICU.

Review on ethics around decision-making - compulsary reading for all NICU staff
If you are to read one paper on neonatal ethics this year, I'd argue that this is the one. Late last year, John Lantos, pediatrician and a leading medical ethicist, published a review in NEJM on the ethics around decision-making in the NICU. The paper is not open-access... but you can surely get it from within your hospital intranet or your university/hospital library. We have a fantastic toolbox in the NICU. We can provide live-saving treatments and support. Most newborns in the NICU survive to good long-term health. However, we also operate in a high-risk environment where some infant may suffer, some infants will die, and some infants will survive with difficult sequele. Which raises the question, by staff and by parents, what is the "right" thing to do in complex situations. When withholding and withdrawing life-sustaining therapies becomes a option to decide upon. How could we navigate in this landscape? IMHO, the review by Lantos is a good starting point on how to form a local practise. Lantos shares his reasoning about we cannot "solve" these discussion with "information" as such. Despite how hard we try, data alone does not lead the whole way. Outcomes is hard to measure, they change over time and we all percieve risks differently. Therefore, information is difficult to standardize. Furthermore, those of us sharing the information will filter our presentation through our subjective selves, coping with opinions, experiences and our expertise in different ways. The better alternative around ethical questions is shared decision-making. Two central quotes of the review is that and that Certainly, the future of neonatal care will bring more ethical questions to us. Refined prenatal diagnostics, the down-shifting boundary of viability and new treatment technologies in the future (like the artificial placenta) will impact how we think about fetal life and postnatal life, what is the "periviable grey zone" and what our fantastic toolbox can do. While improving our skills, from a medical/technical viewpoint, we also need to improve how we cope with the ethics around decision-making processes. Besides reading the review by John Lantos, I can recommend you to see this lecture from theh #99nicuMeetup in Copenhagen 2019, by Eduard Verhagen.

Neonatal hyperbili/phototherapy and long-term risks?
Just read this editorial in JAMA Peds - about screening/tx against neonatal hyperbili phototherapy and reported long-term risks (excess risk of childhood epilepsy, at least in boys) Although confounding (factor X related to both risk of phototherapy and risk of epilepsy) may well be operating, the First Do No Harm-argument is valid IMHO. Of course, highly elevated s-bili is also something that we fear. Anyone discussing/handling these questions in clinical practise and how to balance? https://jamanetwork.com/journals/jamapediatrics/fullarticle/2733861

3rd Future of Neonatal Care Conference In April 2019, we met up at the Future of Neonatal Care conference, AKA the #99nicuMeetup, in Copenhagen, DK. More than 200 people from 32 countries had four intensive days together. Our sincere Thank You to all delegates, faculty members and Partners for making the #99nicuMeetup the event it has become. Without You coming to "share and care", there would be no dynamics, no laughter, and no conference. We share the conference over Twitter (see hashtag #99nicuMeetup). And now we also publish (most) video-recorded lectures, in the playlist below. How to navigate in the playlist? See screen shots below: click the playlist symbol in the top left corner. And close the panel of videos but clicking on the "X".
