Weight

  • ​It is important to know the weight of the child being admitted, as this determines rate of fluid administration and drug dosing.  All medications should be clearly prescribed as amount/weight/time.  E.g. mcg/kg/min, mg/kg/dose.  This will be checked by the bedside nurse prior to any dose being administered.
  • The recommended source for medication dosing in children is the book "drug doses" by Frank Shann, available on the paediatric trolley.  There is also a BNF for children available.
