FEED NOW AND RECHECK - DO NOT WAIT FOR THE REFERRAL [1st line] Adult Source Neonatal Hypoglycemia - StatPearls (NCBI Bookshelf NBK537105) - https://www.ncbi.nlm.nih.gov/books/NBK537105/ Why The first action is a feed and a repeat glucose, not a telephone call. Feeding works within minutes, referral does not, and the harm here is done by the hours a baby spends low while transport is arranged. Screen the babies who are at risk before they are symptomatic, because most of them look well. Caution FEED FIRST - where the baby has a low sugar but no symptoms, the best thing to do is feed more often. Getting breastfeeding started early matters for every newborn. Re-check the blood glucose an hour after the feed. WHICH BABIES TO SCREEN, AND WHEN - the latest AAP guidance screens a late preterm or term baby who shows symptoms of a low sugar, and screens the highest-risk babies without symptoms too, across the first 12 to 24 hours after birth. The at-risk group it names: late preterm babies of 34 to 36.6 weeks' gestation, term babies small for their gestational age, babies born to diabetic mothers, and babies large for their gestational age. For those, the AAP wants feeding begun inside the first hour after birth, and the first glucose measured 30 minutes after that first feed. AND WHICH BABIES NOT TO - a healthy term baby, after an uncomplicated pregnancy and birth, does NOT need the sugar screened or watched as a routine. Sticking every well newborn produces false alarms and separates mothers from babies for nothing. THE NUMBERS TO ACT ON - the AAP aims for a blood glucose at or above 45 mg/dL before each routine feed, and intervenes below 40 mg/dL during the first 4 hours after birth, and below 45 mg/dL from 4 hours to 24 hours. A different society sets a higher target: the PES wants above 50 mg/dL in an at-risk baby with no congenital disorder suspected, over the first 48 hours, and above 60 mg/dL after that. The two guidelines genuinely disagree and the article says so; treat the lower thresholds as the floor, not as the aim. WHO NEEDS A DRIP AND A NEONATAL UNIT - three groups. Any baby with symptoms whose glucose is under 40 mg/dL. Any baby whose hypoglycaemia persists despite feeding more often. And an at-risk baby without symptoms whose glucose is extremely low: under 25 mg/dL during the first 4 hours after birth, or under 35 mg/dL from 4 hours to 24 hours. Those three go to the neonatal unit. A LOW SUGAR IS NOT A DIAGNOSIS ON ITS OWN - what a hypoglycaemic newborn shows is non- specific, and it overlaps with prematurity, with sepsis, with hypoxic-ischaemic encephalopathy and with a low sodium. Treat the sugar, then look for the sepsis. THE BABY WHO WILL NOT STAY UP IS A DIFFERENT PROBLEM - a baby needing intravenous dextrose at a high rate, above 12 to 16 mg/kg/minute, or needing it beyond 5 days, more often has a persistent cause behind the hypoglycaemia. Where a baby cannot hold those glucose targets on a regular feeding schedule, look for that persistent cause before sending them home. The recommendation is to bring endocrinology or genetics in early. WHY IT IS WORTH THE FUSS - a hypoglycaemia that is severe and goes on can end badly indeed: lasting neurodevelopmental disability, cerebral palsy, death. The article is honest that the evidence on mild, brief, asymptomatic dips is weak, and that is a reason to avoid over-treating a well baby, not a reason to leave a symptomatic one. DO NOT COST THE MOTHER HER MILK SUPPLY TO CHASE A NUMBER - giving formula risks the establishment of breastfeeding, and it changes the newborn's microbiome, which may raise the risk of infection and of allergy later. The approach that works best is the one that keeps mother and baby together and gets breastfeeding going early. 2. GLUCOSE (DEXTROSE) [1st line] Adult Peds 200 mg/kg/dose (200 mg/kg IS 2 mL/kg OF 10% GLUCOSE - a 3 kg baby gets 6 mL. Give the bolus and move the baby; the infusion that follows it, 5 to 8 mg/kg per minute, needs a pump and hourly glucose measurements and belongs in a neonatal unit. Do not give 25% or 50% glucose to a newborn - the article's regimen is 10% throughout. There is no adult indication here, so no adult dose is printed. Neonatal hypoglycaemia is a newborn problem; the babies in question weigh 2 to 5 kg.) 3kg -> 600 mg/dose 4kg -> 800 mg/dose 5kg -> 1000 mg/dose This mg/kg figure applies up to 5 kg only - above that, dose on specialist advice Source Neonatal Hypoglycemia - StatPearls (NCBI Bookshelf NBK537105) - https://www.ncbi.nlm.nih.gov/books/NBK537105/ Why For the baby who is symptomatic, or who stays low after feeding. Indication: the article puts any symptomatic infant whose glucose is below 40 mg/dL, and any infant still hypoglycaemic despite more frequent feeds, among those needing the neonatal intensive care unit and intravenous dextrose. Amount: a bolus of 200 mg/kg - which is 2 mL/kg of dextrose 10% - and then a continuous dextrose 10% infusion, 5 to 8 mg/kg/min, which comes to 80 to 100 mL/kg/day, aiming to hold the blood glucose between 40 and 50 mg/dL. Caution MONITOR HOURLY ONCE THE DRIP IS RUNNING - a baby on an intravenous dextrose infusion is watched closely, with the blood glucose measured as often as hourly through the first 12 hours, and less often once the target is being held. THE BABY OF A DIABETIC MOTHER TAKES LESS, NOT MORE - where the mother is diabetic, a reduced glucose infusion rate of 3 to 5 mg/kg/minute is an option, so as to stimulate the pancreas as little as possible and hold down the baby's own insulin. Pushing glucose at a hyperinsulinaemic baby drives the insulin that caused the problem. BUCCAL DEXTROSE GEL IS THE ALTERNATIVE WHERE IT IS AVAILABLE - dextrose gel at 200 mg/kg, rubbed into the inside of the cheek, works as an alternative treatment in a late preterm or term baby without symptoms. The article adds that it cuts admissions to intensive care for intravenous dextrose, and that it helps breastfeeding and the bond between mother and baby. It is for the ASYMPTOMATIC baby; a symptomatic one needs the drip. No dextrose gel product was found in the Egyptian register, so it is named here rather than offered as a row. SECOND-LINE DRUGS ARE NOT PRIMARY-CARE DRUGS - the article names corticosteroids, glucagon and diazoxide with amounts for persistent hypoglycaemia. Every one of them is given after a cause has been sought, under endocrine supervision, and none is printed as a row here. Glucagon in particular rests on the baby having enough glycogen stored, which a small or preterm baby does not. THE POINT OF THE BOLUS IS TO BUY TIME, NOT TO FINISH THE JOB - a single bolus without an infusion behind it is followed by a rebound fall. Give it while transport is being arranged, not instead of arranging transport. Egypt GLUCOSE 40% (MOTTAHEDOON) I.V. INF. 25 ML AL MOTTAHEDOON PHARMA 1.00 EGP DEXTROSE 50% (OTSUKA) I.V.
