(Not Resuscitation) UHL Paediatric Intensive
               Care Guideline
1.Introduction and to whom guideline applies

Calcium is one of the most abundant elements in the human body and has a wide
range of physiological roles including acting as enzyme co-factors, facilitating
neurotransmitter release, muscle contraction and in forming structural parts of the
body.
The majority of the body’s calcium is within the teeth and bones, with smaller
amounts in either intracellular stores or circulating in the blood. Of the fraction
circulating in the blood approximately 55% is bound to albumin or held in other
complexes; only 45% is free ionised calcium, which is the most physiologically
important component and gives the best indication of clinically significant
hypocalcaemia.
Calcium is normally absorbed from the diet and may be excreted from the kidneys.
Low levels may result from inadequate intake, poor absorption, excessive losses or
abnormal bone turnover. Homeostatic control of calcium levels is usually under the
control of parathyroid hormone and calcitonin. Abnormally low levels may need
intervention to correct them, for which this guideline intends to provide some
guidance.

The policy applies to all healthcare professionals involved in the prescribing and
administration of oral and injectable calcium supplements to patients within the
childrens’ hospital.
The guideline for the management of hypocalcaemia is only applicable paediatric
wards including intensive care areas.

2.Treatment regimens & monitoring

                                      Hypocalcaemia

                                      Requires correction if:
                         1. Ionized calcium 1.5 mmol/L consider stopping treatment

                                         Access:
           Where possible administer calcium gluconate via a central line
 Check that the central venous line bleeds back, or that the peripheral line flushes
                              easily, before administering
           Look for evidence of leakage around cannula site
    If administered centrally use the most distal lumen available
        If using peripheral access check for extravasation every 15 minutes.

                                      Compatibility:
                              Compatible with potassium
                              Compatible with inotropes
     Children requiring calcium infusions should be monitored in an HDU or ICU
                                     environment

Non-acute Hypocalcaemia

                      Consider calcium boluses via oral route in form of
                        Alliance Calcium Syrup (0.51mmols/ml)
                                 (Full feeds not essential)

                                            NIL BY MOUTH

                                   Consider maintenance IV fluids.
                                   or
                                   IV calcium gluconate 1mmol/kg/day

                                     Acute Hypocalcaemia

Calcium gluconate                                                   Calcium chloride
(1st line) intermittent infusion                    or              (2nd line) intermittent
peripherally or centrally                                           infusion centrally
0.11mmol/kg/dose (over 10                                           0.11mmol/kg/dose (over 10
minutes)                                                            minutes)

Check ionised calcium level following each intermittent infusion

If requiring multiple intermittent infusions to maintain calcium level, or for inotropic
use, a continuous central infusion of calcium gluconate 0.1-1mmol/kg/day can be
commenced (see IV monograph)

Ensure ionised calcium level is checked every 2- to 3- hours on blood gas samples
while the infusion is running, and periodically thereafter
