Sodium Bicarbonate Half correction for Metabolic acidosis: Base deficit (mmol/l) x body weight (Kg) x 0.3 = mmol of bicarbonate required 4.2% sodium bicarbonate contains 0.5 mmol bicarbonate / ml. Always try to correct the underlying condition leading to metabolic acidosis. The correction if necessary, should ideally be undertaken over several hours as a slow infusion. This correction will always undercorrect the acidaemia but is usually sufficient. THAM is an alternative base. It has the advantage of being sodium free and shouldn t raise the PaCO 2. Therefore this may be preferred if the baby has very high sodium or PaCO 2. However it stops premature babies breathing so should only be used in babies who are being ventilated. 1 ml of 7.2% THAM is approx equivalent to 1 mmol bicarbonate. Bicarbonate infusion through arterial line in extremely premature babies (<26 weeks gestation): Extremely preterm neonates (<26/40 weeks) can be anticipated to develop a metabolic acidosis. This can be due to renal tubular loss of bicarbonate accompanied by chloride retention leading to a hyperchloremic metabolic acidosis. In the short term, metabolic acidosis is associated with the following abnormalities: Inhibition of surfactant production Increases in pulmonary vascular resistance Reduction in cardiac output Abnormal EEGs (consequences unclear) In the longer term, a ph <7.2 is associated with an abnormal neurodevelopmental outcome in preterm neonates <1000g. Metabolic acidosis is predominantly corrected by identifying its cause. Whether correction of metabolic acidosis improves outcome has not been studied in a randomised trial. 7
However, if bicarbonate treatment is given, it is best administered slowly. Twenty-four hour intravenous infusions are associated with decreased mortality, whereas rapid infusions are associated with an increased incidence of IVH. 5 Hence, prophylactic arterial infusion of low dose bicarbonate in this high risk population is established clinical management in many UK neonatal units. Route: Dose: Preparation: Bicarbonate should be infused through a UA or peripheral arterial line. 0.54mmols of NaHCO 3 administered per 24-hours (or about 1mmol/kg/day for a 500g neonate). 3mls of 4.2% NaHCO 3 (=1.5mmol) 16mls of sterile water for injection 1ml of hepsaline equivalent to 10 iu of heparin Total volume 20 mls with heparin conc. of 0.5 i.u/ml Infusion rate: Run solution at 0.3ml/hr Use a three way tap in between the baby and the transducer to infuse continuous bicarbonate solution as above through the side arm (Transducer set in a normal way with 0.45% hepsaline attached but not infusing from the syringe). During sampling stop bicarbonate infusion, sample in the usual way and flush with hepsaline from the syringe. Once flushed restart bicarbonate solution. 8

-- INSULIN Plastic tubing used for infusion should be flushed with at least 20mls of insulin solution and primed by for at least 20 minutes before use because insulin binds to the tubing resulting in decreased availability to the baby. It is extremely important that any replacement set is also fully primed. Do not use the line to give any other medications e.g. antibiotics as this will result in a bolus of insulin with potentially significant hypoglycaemia. If there is only one peripheral cannula other infusions should be administered at the hub of the cannula. Insulin infusion Add 25 units/kg of insulin to 50 ml of i.v. solution, then infuse at 0.2 ml/hr (which equates to 0.1 units/kg/hr). Infuse at 0.05 0.1units/kg/hr. The following sliding scale is a recommendation, but may need adjusting to suit individual requirements. Blood Glucose Rate of infusion of solution >20 mmol/l 0.2ml/hr (0.1 units/kg/hr) 8 20 mmol/l 0.1 ml/hr (0.05 unit/kg/hr) < 8 mmol/l Stop insulin infusion If fluids are restricted a double strength infusion can be prepared by diluting 50 units/kg to 50 ml i.v. solution where 0.1 ml/hour = 0.1 unit/kg/hour. No more than 0.5 units/kg/hr is usually needed. Some growth retarded and very pre-term babies can be very sensitive to the effects of insulin so monitor blood glucose very frequently at the start of the infusion. Diluents: Sodium chloride (0.45% and 0.9%) and Dextrose 5% and 10%. The infusion should be freshly prepared every 24 hours. Vials of insulin should be stored in a refrigerator at 2 8 o C. Do not use if the solution appears hazy or coloured. Known compatibilities: Can be added (terminally) to a line containing: Dobutamine, Heparin, Midazolam, Milrinone, Morphine, Potassium, TPN (Aqueous), Vancomycin Known incompatibilities: Aminophylline, Phenytoin, Phenobarbitone, Dopamine, sodium bicarbonate 20
Liver medication for babies with conjugated jaundice Babies with neonatal cholestasis where the conjugated bilirubin fraction is greater than 50 umol/l will need additional supplements of fat soluble vitamins. This recommendation is adapted from the King s college, London guidelines 2009 for neonatal cholestatsis. Option 1: Dalavit 0.3 mls BD OR Abidec 0.3mls BD orally Vitamin E 10mg/Kg OD orally Vitamin K 1mg OD orally / intravenously Ursodeoxycholic acid 5-10mg/Kg TDS orally Option 2 (If medications in option 1 are not available): Ketovite liquid 5mls OD orally Ketovite tablet 3tab crushed along with Ketovite liquid Vitamin K 1mg OD orally / intravenously Ursodeoxycholic acid 5-10mg/Kg TDS orally In addition, for both options, you may consider Alfacalcidol 5-10nanogram/kg/day if you have confirmed evidence of Vitamin D deficiency. You will need close monitoring of serum calcium and phosphate levels. 21
