The webinar (#14) is now available for watching in the Tiny Baby Collaborative website.

We have published our recommended standard concentrations in a position statement last year. While the majority of the statement is in Hebrew, the recommendations are in English and are attached below. The full text can be found here and can be translated using AI/Google Translate as needed (or you can ask me for any clarifications). I also played a bit with Gemini recently and created this "NICU Smart Infusion Tool" (also attached, should work offline from any browser, just download and open in browser - free to use and share). This tool takes as input a medication from a predetermined list of drugs administered continuously in the NICU, infant weight and dosage OR delivery rate, and calculates the pump rate, delivered dose and total volume of fluid per day as output for each of the standard concentrations. These calculations complement the recommendation for using standard concentrations and should help the clinician choose the most appropriate concentration for any individual patient. It should be noted that the various concentrations were originally meant for different weight categories, but with accumulated experience we have found that for e.g. Fentanyl, using the 2.5 mcg/mL for very small babies may actually load them with excess fluids, so in practice we use 5 or 10 mcg/mL (using the tool as a decision supporting system). So while all of the recommendations are evidence-based, some are pending revision, but can still be used at the discretion of the clinician. For other common drugs administered as intermittent infusion, we use the following concentrations: Ampicillin: 25 mg/mL or 50 mg/mL (when higher doses are needed, e.g., for meningitis, or for very large babies). Caffeine: 5 mg/mL or 10 mg/mL (when a loading dose is required) Fluconazole: 2 mg/mL or 1 mg/mL (for very small babies) Darbepoetin: 40 mcg/mL And in general, even for rarely administered drugs with no established standard concentration, we try to prepare them in a concentration that will be easy to calculate, easy to dilute down to and produce a volume that will be easy to administer (i.e., not too small).

Our guidelines (a mid-size hospital in Israel with a 25-bed NICU) also instruct to give 3 mg/kg every 72 hours for eligible infants and decision to treat is based on the presence of a central line of any kind as a primary determinant and on corrected age/birth weight as a secondary determinant. There are other secondary determinants if the above criteria are negative (NEC diagnosis, prolonged treatment with broad-spectrum antibiotics), see the attached diagram.

Hi all, Yesterday, the Tiny Baby Collaborative held a webinar about using hydrocortisone in extremely preterm infants (under 23 weeks of gestational age), which featured Dr. Satoshi Kusuda from the Neonatal Research Network of Japan and Dr. Erik Jensen from Stanford University (the webinar will probably be available in the near future here: https://www.tinybabycollaborative.org/webinars) I was unable to attend the entire event, but was wondering if anyone here also attended and maybe we can discuss this issue. My understanding is that in such extremely preterm infants, adrenal insufficiency is very common (which makes sense) and with the added stress of premature delivery and adaptation, circulatory collapse is a common risk. The two experts presented several papers and reviews, but I am afraid I am not clear on the bottom line (beside the fact that we need more studies, as always). Hydrocortisone was shown to reduce BPD and failure to extubate, as well as in-hospital death, but was shown to increase the risk for hyperglycemia. A comparison with dexamethasone was also shown, where dexamethasone was shown to have a lower risk ratio for failure to extubate (0.61 vs. 0.79 for hydrocortisone). The experts concluded that no robust data inform use of hydrocortisone for respiratory or neurodevelopmental indications in infants born before 23 weeks of gestation. Interested to hear your thoughts about this, as well as your practices. How do YOU use hydrocortisone (or other corticosteroids) in tiny infants? Here are some of the papers that were cited in the webinar: Effect of Prophylaxis for Early Adrenal Insufficiency Using Low-Dose Hydrocortisone in Very Preterm Infants: An Individual Patient Data Meta-Analysis Early (< 7 days) systemic postnatal corticosteroids for prevention of bronchopulmonary dysplasia in preterm infants Postnatal Corticosteroids To Prevent Bronchopulmonary Dysplasia

Thanks. So if I understand correctly, your process is similar to the one depicted in the figure in the original post? Pharmacy prepares a standard concentration for all infants, from which the exact dose is calculated and administered based on specific weight-based dosage?

Interesting. So the infusion pump gets the weight from the medical record automatically? If yes, then this removes another step of "manual" calculation, which surely contributes to less dosing errors. However, you still need to factor in the weight when the nurse connects the syringe to the pump and prepares to deliver the dose. If the drug solution is in mg/mL and the dose is given as a dosing rate (mg/kg*hour), then when dividing the dosing rate by the concentration you get mL/kg*hour, which is a weight-adjusted delivery rate. Is the weight factored in automatically by the pump, i.e., the pump calculates the final delivery rate in mL/hour?

Dear colleagues, I was wondering what your practice is regarding preparation of drugs for intravenous administration in the NICU? Are your units employing an individualized approach, whereby each drug is prepared for each infant in the prescribed dose and thus administered, or a 'standard concentration' approach, whereby a drug solution is prepared in a fixed concentration and the volume to be administered is calculated from that concentration? In our unit we employ the latter approach, as can be observed in the attached figure. The doctor prescribes a weight-based dose, the pharmacist prepares a standard concentration solution in sufficient volume to account for dose and tubing, and the nurse calculates the volume that would provide the precise prescribed dose and sets the syringe pump to deliver that dose. I am interested to know of other units working this way, as well as other approaches. Please share for everyone's benefit!

Hi all, I am a neonatal and pediatric pharmacist from Israel, and I regularly provide consultations on drugs and breastfeeding in our NICU and obstetrics wards. I am delighted to see this discussion and the dyad-centered approach, which strives to take into account both mother and infant considerations and wishes to make an educated decision backed by careful risk management. This is without a doubt the right course of action! I will share the resources I am aware of and often use, and even though some have already been mentioned, perhaps this list may be useful as a convenient and accessible collection for your practices and everyday needs: Lactmed - An American, NIH-sponsored, freely available resource. Comprehensive and regularly updated. E-lactancia - A Spanish resource, available in English and Spanish, freely accessible. It should be noted that it also provides information on exposures other than pharmaceuticals (some food supplements, phytotherapy). MotherToBaby - An American resource powered by The Organization of Teratology Information Specialists (OTIS). They offer a vast collection of fact sheets for various exposures, including pharmaceuticals but many other exposures as well. While this is patient-oriented information, it may still be useful for professionals to observe the approach of OTIS to exposure with scarce evidence. Hale's Medications & Mothers' Milk - a well-known, long-standing American resource by Thomas Hale and Kaytlin Krutsch. Available digitally (to paying subscribers) and in print, this collection provides evidence summaries for many exposures (mostly pharmaceuticals, but not solely). One of its highlights is the pharmacokinetic data table that accompanies each monograph, which is very helpful for a quick observation, before diving into the evidence. It also contains some appendices that are worth checking out (drugs that may alter the taste of human milk and more). InfantRisk Center - This is the teratology information center in Texas Tech University that produces Hale's Medications & Mothers' Milk, and its online website and community offers additional resources and articles that may complement the book. I suggest checking out the forums, where patients and professionals may ask questions on exposures during breastfeeding and the InfantRisk team responds to them, and the breastfeeding page, which contains many articles on all kinds of exposures during breastfeeding. Academy of Breastfeeding Medicine - This American medical society publishes protocols on various topics related to breastfeeding, some include exposure to certain drug groups. Breastfeeding Medicine - This Journal, published by the Academy of Breastfeeding Medicine and Mary Ann Liebert, offers a myriad of peer-reviewed papers, protocols and publications on breastfeeding. Some material is open access, others require subscription access. It is possible to search the journal page for drug name/family and retrieve appropriate publications. This journal also features publications by Philip O. Anderson, who is also involved in Lactmed. His publications include summaries for various drug families in breastfeeding. Guidelines for anaesthesia and sedation for patients who are breastfeeding - This open-access British publication, which was originally published in 2020 and very recently revised and updated, includes a lot of information on many drugs used for analgesia and sedation in breastfeeding women. Be sure to check out the supporting information, the appendices offer much useful information (including more resources), basic terminology and more. SPS (Specialist Pharmacy Service) "Safety in Breastfeeding" topic - This NHS-supported service has a lot to offer about drugs and pharmacy skills in general, and there is a topic about "Safety in Breastfeeding" that serves as a collection of articles about pharmacotherapy during breastfeeding in general, as well as dedicated articles for certain drugs/drug groups (e.g., antihistamines, GLP-1 receptor agonists, contrast agents, oral anticoagulants, and more). Pharmacokinetics sections in drug labels and general drug databases - When all else fails, one may try to make an educated "guess" about the amount of drug that may pass into breastmilk according to PK parameters, e.g., low bioavailability of injectables, high molecular weight of biological products etc. This list is not complete, but provides a collection of trusted resources for healthcare professionals. I was also happy to see the paper @Annika shared, not only because I was a co-author on this paper, but also because I believe this review captures the 'modern' approach to drug exposure during breastfeeding and provides a holistic view of this topic that may allow NICU professionals to provide preterm infants with human milk that is SO important to them. So I do recommend reading it and applying our suggestions in your practices as you see fit. * A word on OpenEvidence - this is an excellent tool, the most trustworthy AI platform for medical information currently available. However, one should note that in questions about drugs, it often relies on information from FDA drug labels, which - as we know - often provide no safety information for exposure during pregnancy and/or breastfeeding, or even recommend against use of the drug in question. Therefore, always check the sources for OE answer, and if it relies on the label, do check in any of the other sources I listed above. Thank you for raising this topic, and I do hope this will contribute to better care for breastfeeding mothers and infants.
